Symptoms of the condition in males consist of loss of libido, impotence, infertility, shrinkage of the testicles, penis, and prostate, diminished masculinization (e.g., decreased facial and body hair growth), low muscle mass, anxiety, depression, fatigue, vasomotor symptoms (hot flashes), insomnia, headaches, and osteoporosis. In addition, symptoms of hyperestrogenism, such as gynecomastia and feminization, may be concurrently present in males.

In females, hypoandrogenism consist of loss of libido, decreased body hair growth, depression, fatigue, vaginal vasocongestion (which can result in cramps), vasomotor symptoms (e.g., hot flashes and palpitations), insomnia, headaches, osteoporosis and reduced muscle mass. Symptoms of hypoestrogenism may be present in both sexes in cases of severe androgen deficiency (as estrogens are synthesized from androgens).

Hyperandrogenism affects 5-10% of females of reproductive age. Hyperandrogenism can affect both males and females, but is more noticeable in females due to the fact that elevated levels of androgens in females often facilitates virilization. Due to the fact that hyperandrogenism is characterized by the elevation of male sex hormone levels, symptoms of hyperandrogenism in men are often negligible. Hyperandrogenism in females is typically diagnosed in late adolescence with a medical evaluation. The medical evaluation tends to consist of a pelvic exam, observation of external symptoms, and a blood test measuring androgen levels.

Hyperandrogenism, especially high levels of testosterone, can cause serious adverse effects on women’s bodies if left untreated. High testosterone levels have been seen to be associated with obesity, hypertension, amenorrhea(stop of menstrual cycles), and ovulatory dysfunction, which can lead to infertility. The more prominent signs of hyperandrogenism are hirsutism (unwanted growth of hair especially in the abdominal region and places on the back), acne after adolescence, deepening of voice, and alopecia(balding). Hyperandrogenism has also been seen to cause individuals to have a high tolerance to insulin, which can lead to type two diabetes, and dyslipidemia, such as high cholesterol. These effects have also been seen to have a large psychological impact on the individual, sometimes often leading to societal anxiety and depression, especially in adolescent girls and young women. Paired with obesity and hirsutism, it can cause the individual to have low self-esteem, and a poor view of oneself.

The deficiency causes the virilization of XX fetuses. Although they will have normal female internal genitalia, clitoromegaly often results from the high androgen levels in utero, along with ambiguous external genitalia upon birth.

Testosterone may be normal or elevated.

Later, the lack of estrogen results in the presentation of primary amenorrhea and tall stature. The taller than expected height occurs because estrogen normally causes fusion of the epiphyseal growth plates in the bones, and in its absence, the girl will keep growing longer. The gonadotropins LH and FSH will both be elevated and patients present with polycystic ovaries. Furthermore, the low estrogen will predispose those with the condition to osteoporosis.

Observed physiological abnormalities of the condition include a dramatic overexpression of aromatase and, accordingly, excessive levels of estrogens including estrone and estradiol and a very high rate of peripheral conversion of androgens to estrogens. In one study, cellular aromatase mRNA expression was found to be at least 10 times higher in a female patient compared to the control, and the estradiol/testosterone ratio after an injection of testosterone in a male patient was found to be 100 times greater than the control. Additionally, in another study, androstenedione, testosterone, and dihydrotestosterone (DHT) were found to be either low or normal in males, and follicle-stimulating hormone (FSH) levels were very low (likely due to suppression by estrogen, which has antigonadotropic effects as a form of negative feedback inhibition on sex steroid production in sufficiently high amounts), whereas luteinizing hormone (LH) levels were normal.

According to a recent review, estrone levels have been elevated in 17 of 18 patients (94%), while estradiol levels have been elevated only in 13 of 27 patients (48%). As such, estrone is the main estrogen elevated in the condition. In more than half of patients, circulating androstenedione and testosterone levels are low to subnormal. The ratio of circulating estradiol to testosterone is >10 in 75% of cases. FSH levels are said to be consistently low in the condition, while LH levels are in the low to normal range.

It is notable that gynecomastia has been observed in patients in whom estradiol levels are within the normal range. This has been suggested to be due to "in situ" conversion of adrenal androgens into estrone and then estradiol (via local 17β-HSD) in breast tissue (where aromatase activity may be particularly high).

The symptoms of AES, in males, include heterosexual precocity (precocious puberty with phenotypically-inappropriate secondary sexual characteristics; i.e., a fully or mostly feminized appearance), severe prepubertal or peripubertal gynecomastia (development of breasts in males before or around puberty), high-pitched voice, sparse facial hair, hypogonadism (dysfunctional gonads), oligozoospermia (low sperm count), small testes, micropenis (an ususually small penis), advanced bone maturation, an earlier peak height velocity (an accelerated rate of growth in regards to height), and short final stature due to early epiphyseal closure. The incidence of gynecomastia appears to be 100%, with 20 of 30 male cases opting for mastectomy according to a review.

In females, symptoms of AES include isosexual precocity (precocious puberty with phenotypically-appropriate secondary sexual characteristics), macromastia (excessively large breasts), an enlarged uterus, menstrual irregularities, and, similarly to males, accelerated bone maturation and short final height. Of seven females described in one report, three had macromastia (rate of ~43%). A 10-year-old girl with gigantomastia has subsequently also been described.

Fertility, though usually affected to one degree or another—especially in males—is not always impaired significantly enough to prevent sexual reproduction, as evidenced by vertical transmission of the condition by both sexes.

Hypoandrogenism is caused primarily by either dysfunction, failure, or absence of the gonads ("hypergonadotropic") or impairment of the hypothalamus or pituitary gland ("hypogonadotropic"), which in turn can be caused by a multitude of different stimuli, including genetic conditions (e.g., GnRH/gonadotropin insensitivity and enzymatic defects of steroidogenesis), tumors, trauma, surgery, autoimmunity, radiation, infections, toxins, drugs, and many others. Alternatively, it may be the result of conditions such as androgen insensitivity syndrome or hyperestrogenism. More simply, old age may also be a factor in the development of hypoandrogenism, as androgen levels decline with age.

Aromatase deficiency in the baby can also affect the mother during gestation, with cystic acne, hirsutism, deepening of the voice, and clitoromegaly. Increased circulating testosterone levels are the cause. The mother's symptoms resolve after she gives birth.

The symptoms of isolated 17,20-lyase deficiency, in males, include pseudohermaphroditism (i.e., feminized, ambiguous, or mildly underdeveloped (e.g., micropenis, perineal hypospadias, and/or cryptorchidism (undescended testes)) external genitalia), female gender identity, and, in non-complete cases of deficiency where partial virilization occurs, gynecomastia up to Tanner stage V (due to low androgen levels, which results in a lack of suppression of estrogen); in females, amenorrhoea or, in cases of only partial deficiency, merely irregular menses, and enlarged cystic ovaries (due to excessive stimulation by high levels of gonadotropins); and in both sexes, hypergonadotropic hypogonadism (hypogonadism despite high levels of gonadotropins), delayed, impaired, or fully absent adrenarche and puberty with an associated reduction in or complete lack of development of secondary sexual characteristics (sexual infantilism), impaired fertility or complete sterility, tall stature (due to delayed epiphyseal closure), eunuchoid skeletal proportions, delayed or absent bone maturation, and osteoporosis.

Aromatase excess syndrome (AES or AEXS), also sometimes referred to as familial hyperestrogenism or familial gynecomastia, is a rare genetic and endocrine syndrome which is characterized by an overexpression of aromatase, the enzyme responsible for the biosynthesis of the estrogen sex hormones from the androgens, in turn resulting in excessive levels of circulating estrogens and, accordingly, symptoms of hyperestrogenism. It affects both sexes, manifesting itself in males as marked or complete phenotypical feminization (with the exception of the genitalia; i.e., no pseudohermaphroditism) and in females as hyperfeminization.

To date, 30 males and 8 females with AES among 15 and 7 families, respectively, have been described in the medical literature.

If the cause can be traced to the hypothalamus or pituitary, the cause is considered central. Other names for this type are "complete" or "true precocious" puberty.

Causes of central precocious puberty can include:

- damage to the inhibitory system of the brain (due to infection, trauma, or irradiation),

- hypothalamic hamartoma produces pulsatile gonadotropin-releasing hormone (GnRH),

- Langerhans cell histiocytosis, or

- McCune–Albright syndrome.

Central precocious puberty can be caused by intracranial neoplasm, infection (most commonly central nervous system tuberculosis especially in developing countries), trauma, hydrocephalus, and Angelman syndrome. Precocious puberty is associated with advancement in bone age, which leads to early fusion of epiphyses, thus resulting in reduced final height and short stature.

Precocious puberty can make a child fertile when very young, with the youngest mother on record being Lina Medina, who gave birth at the age of 5 years, 7 months and 17 days, in one report and at 6 years 5 months in another.

"Central precocious puberty (CPP) was reported in some patients with suprasellar arachnoid cysts (SAC), and SCFE (slipped capital femoral epiphysis) occurs in patients with CPP because of rapid growth and changes of growth hormone secretion."

If no cause can be identified, it is considered idiopathic or constitutional.

Individuals with mild (or minimal) androgen insensitivity syndrome (grade 1 on the Quigley scale) are born phenotypically male, with fully masculinized genitalia; this category of androgen insensitivity is diagnosed when the degree of androgen insensitivity in an individual with a 46,XY karyotype is great enough to impair virilization or spermatogenesis, but is not great enough to impair normal male genital development. MAIS is the mildest and least known form of androgen insensitivity syndrome.

The existence of a variant of androgen insensitivity that solely affected spermatogenesis was theoretical at first. Cases of phenotypically normal males with isolated spermatogenic defect due to AR mutation were first detected as the result of male infertility evaluations. Until then, early evidence in support of the existence of MAIS was limited to cases involving a mild defect in virilization, although some of these early cases made allowances for some degree of impairment of genital masculinization, such as hypospadias or micropenis. It is estimated that 2-3% of infertile men have AR gene mutations.

Examples of MAIS phenotypes include isolated infertility (oligospermia or azoospermia), mild gynecomastia in young adulthood, decreased secondary terminal hair, high pitched voice, or minor hypospadias repair in childhood. The external male genitalia (penis, scrotum, and urethra) are otherwise normal in individuals with MAIS. Internal genitalia, including Wolffian structures (the epididymides, vasa deferentia, and seminal vesicles) and the prostate, is also normal, although the bitesticular volume of infertile men (both with and without MAIS) is diminished; male infertility is associated with reduced bitesticular volume, varicocele, retractile testes, low ejaculate volume, male accessory gland infections (MAGI), and mumps orchitis. The incidence of these features in infertile men with MAIS is similar to that of infertile men without MAIS. MAIS is not associated with Müllerian remnants.

Mutations that result in some residual 21-hydroxylase activity cause milder disease, traditionally termed simple virilizing CAH (SVCAH). In these children the mineralocorticoid deficiency is less significant and salt-wasting does not occur. However, genital ambiguities are possible.

Isolated 17,20-lyase deficiency (ILD), also called isolated 17,20-desmolase deficiency, is a rare endocrine and autosomal recessive genetic disorder which is characterized by a complete or partial loss of 17,20-lyase activity and, in turn, impaired production of the androgen and estrogen sex steroids. The condition manifests itself as pseudohermaphroditism (partially or fully underdeveloped genitalia) in males, in whom it is considered to be a form of intersex, and, in both sexes, as a reduced or absent puberty/lack of development of secondary sexual characteristics, resulting in a somewhat childlike appearance in adulthood (if left untreated).

Unlike the case of combined 17α-hydroxylase/17,20-lyase deficiency, isolated 17,20-lyase deficiency does not affect glucocorticoid production (or mineralocorticoid levels), and for that reason, does not result in adrenal hyperplasia or hypertension.

In medicine, precocious puberty is puberty occurring at an unusually early age. In most cases, the process is normal in every aspect except the unusually early age, and simply represents a variation of normal development. In a minority of children, the early development is triggered by a disease such as a tumor or injury of the brain. Even when there is no disease, unusually early puberty can have adverse effects on social behavior and psychological development, can reduce adult height potential, and may shift some lifelong health risks. Central precocious puberty can be treated by suppressing the pituitary hormones that induce sex steroid production. The opposite condition is delayed puberty.

The term is used with several slightly different meanings that are usually apparent from the context. In its broadest sense, and often simplified as early puberty, "precocious puberty" sometimes refers to any physical sex hormone effect, due to any cause, occurring earlier than the usual age, especially when it is being considered as a medical problem. Stricter definitions of "precocity" may refer only to central puberty starting before a statistically specified age based on percentile in the population (e.g., 2.5 standard deviations below the population mean), on expert recommendations of ages at which there is more than a negligible chance of discovering an abnormal cause, or based on opinion as to the age at which early puberty may have adverse effects. A common definition for medical purposes is onset before 8 years in girls or 9 years in boys.

The mineralocorticoid aspect of severe 3β-HSD CAH is similar to those of 21-hydroxylase deficiency. Like other enzymes involved in early stages of both aldosterone and cortisol synthesis, the severe form of 3β-HSD deficiency can result in life-threatening salt-wasting in early infancy. Salt-wasting is managed acutely with saline and high-dose hydrocortisone, and long-term fludrocortisone.

The sex steroid consequences of severe 3β-HSD CAH are unique among the congenital adrenal hyperplasias: it is the only form of CAH that can produce ambiguity in both sexes. As with 21-hydroxylase deficient CAH, the degree of severity can determine the magnitude of over- or undervirilization.

In an XX (genetically female) fetus, elevated amounts of DHEA can produce moderate virilization by conversion in the liver to testosterone. Virilization of genetic females is partial, often mild, and rarely raises assignment questions. The issues surrounding corrective surgery of the virilized female genitalia are the same as for moderate 21-hydroxylase deficiency but surgery is rarely considered desirable.

The extent to which mild 3β-HSD CAH can cause early appearance of pubic hair and other aspects of hyperandrogenism in later childhood or adolescence is unsettled. Early reports about 20 years ago suggesting that mild forms of 3β-HSD CAH comprised significant proportions of girls with premature pubic hair or older women with hirsutism have not been confirmed and it now appears that premature pubarche in childhood and hirsutism after adolescence are not common manifestations of 3β-HSD CAH.

Undervirilization of genetic males with 3β-HSD CAH occurs because synthesis of testosterone is impaired in both adrenals and testes. Although DHEA is elevated, it is a weak androgen and too little testosterone is produced in the liver to offset the deficiency of testicular testosterone. The degree of undervirilization is more variable, from mild to severe. Management issues are those of an undervirilized male with normal sensitivity to testosterone.

If the infant boy is only mildly undervirilized, the hypospadias can be surgically repaired, testes brought into the scrotum, and testosterone supplied at puberty.

Management decisions are more difficult for a moderately or severely undervirilized genetic male whose testes are in the abdomen and whose genitalia look at least as much female as male. Male sex can assigned and major reconstructive surgery done to close the midline of the perineum and move the testes into a constructed scrotum. Female sex can be assigned and the testes removed and vagina enlarged surgically. A recently advocated third choice would be to assign either sex and defer surgery to adolescence. Each approach carries its own disadvantages and risks. Children and their families are different enough that none of the courses is appropriate for all.

Signs of hyperestrogenism may include heightened levels of one or more of the estrogen sex hormones (usually estradiol and/or estrone), lowered levels of follicle-stimulating hormone and/or luteinizing hormone (due to suppression of the hypothalamic–pituitary–gonadal axis by estrogen), and lowered levels of androgens such as testosterone (generally only relevant to males). Symptoms of the condition in women may consist of menstrual irregularities, amenorrhea, abnormal vaginal bleeding, and enlargement of the uterus and breasts. It may also present as isosexual precocity in children and as hypogonadism, gynecomastia, feminization, impotence, and loss of libido in males. If left untreated, hyperestrogenism may increase the risk of estrogen-sensitive cancers such as breast cancer later in life.

Estrogen insensitivity syndrome (EIS), or estrogen resistance, is a form of congenital estrogen deficiency or hypoestrogenism which is caused by a defective estrogen receptor (ER) – specifically, the estrogen receptor alpha (ERα) – that results in an inability of estrogen to mediate its biological effects in the body. Congenital estrogen deficiency can alternatively be caused by a defect in aromatase, the enzyme responsible for the biosynthesis of estrogens, a condition which is referred to as aromatase deficiency and is similar in symptomatology to EIS.

EIS is an extremely rare occurrence. As of 2016, there have been three published reports of EIS, involving a total of five individuals. The reports include a male case published in 1994, a female case published in 2013, and a familial case involving two sisters and a brother which was published in 2016.

EIS is analogous to androgen insensitivity syndrome (AIS), a condition in which the androgen receptor (AR) is defective and insensitive to androgens, such as testosterone and dihydrotestosterone (DHT). The functional opposite of EIS is hyperestrogenism, for instance that seen in aromatase excess syndrome.

The classic feature of gynecomastia is male breast enlargement with soft, compressible, and mobile subcutaneous chest tissue palpated under the areola of the nipple in contrast to softer fatty tissue. This enlargement may occur on one side or both. Dimpling of the skin and nipple retraction are not typical features of gynecomastia. Milky discharge from the nipple is also not a typical finding, but may be seen in a gynecomastic individual with a prolactin secreting tumor. An increase in the diameter of the areola and asymmetry of chest tissue are other possible signs of gynecomastia.

Males with gynecomastia may appear anxious or stressed due to concerns about the possibility of having breast cancer.

Hyperestrogenism, hyperestrogenic state, or estrogen excess, is a medical condition characterized by an excessive amount of estrogenic activity in the body.

Spinal and bulbar muscular atrophy (SBMA), also known as Kennedy's disease, is a severe neurodegenerative syndrome that is associated with a particular mutation of the androgen receptor's polyglutamine tract called a trinucleotide repeat expansion. SBMA results when the length of the polyglutamine tract exceeds 40 repetitions.

Although technically a variant of MAIS, SBMA's presentation is not typical of androgen insensitivity; symptoms do not occur until adulthood and include neuromuscular defects as well as signs of androgen inaction. Neuromuscular symptoms include progressive proximal muscle weakness, atrophy, and fasciculations. Symptoms of androgen insensitivity experienced by men with SBMA are also progressive and include testicular atrophy, severe oligospermia or azoospermia, gynecomastia, and feminized skin changes despite elevated androgen levels. Disease onset, which usually affects the proximal musculature first, occurs in the third to fifth decades of life, and is often preceded by muscular cramps on exertion, tremor of the hands, and elevated muscle creatine kinase. SBMA is often misdiagnosed as amyotrophic lateral sclerosis (ALS) (also known as Lou Gehrig's disease).

The symptoms of SBMA are thought to be brought about by two simultaneous pathways involving the toxic misfolding of proteins and loss of AR functionality. The polyglutamine tract in affected pedigrees tends to increase in length over generations, a phenomenon known as "anticipation", leading to an increase in the severity of the disease as well as a decrease in the age of onset for each subsequent generation of a family affected by SBMA.

The symptoms of Leydig cell hypoplasia include pseudohermaphroditism (i.e., feminized, ambiguous, or relatively mildly underdeveloped (e.g., micropenis, severe hypospadias, and/or cryptorchidism (undescended testes)) external genitalia), a female gender identity or gender variance, hypergonadotropic hypogonadism (hypogonadism despite high levels of gonadotropins), delayed, impaired, or fully absent puberty with an associated reduction in or complete lack of development of secondary sexual characteristics (sexual infantilism), impaired fertility or complete sterility, tall stature (due to delayed epiphyseal closure), eunuchoid skeletal proportions, delayed or absent bone maturation, and osteoporosis.

The androgen excess is mild enough that virilization is not apparent or goes unrecognized at birth and in early childhood. However, androgen levels are above normal and slowly rise during childhood, producing noticeable effects between 2 and 9 years of age.

Appearance of pubic hair in mid-childhood is the most common feature that leads to evaluation and diagnosis. Other accompanying features are likely to be tall stature and accelerated bone age (often 3–5 years ahead). Often present are increased muscle mass, acne, and adult body odor. In boys the penis will be enlarged. Mild clitoral enlargement may occur in girls, and sometimes a degree of prenatal virilization is recognized that may have gone unnoticed in infancy.

The principal goals of treatment of non-classical CAH are to preserve as much growth as possible and to prevent central precocious puberty if it has not already been triggered. These are more difficult challenges than in CAH detected in infancy because moderate levels of androgens will have had several years to advance bone maturation and to trigger central puberty before the disease is detected.

A diagnosis of non-classical CAH is usually confirmed by discovering extreme elevations of 17α-hydroxyprogesterone along with moderately high testosterone levels. A cosyntropin stimulation test may be needed in mild cases, but usually the random levels of 17OHP are high enough to confirm the diagnosis.

The mainstay of treatment is suppression of adrenal testosterone production by a glucocorticoid such as hydrocortisone. Mineralocorticoid is only added in cases where the plasma renin activity is high.

A third key aspect of management is suppression of central precocious puberty if it has begun. The usual clues to central puberty in boys are that the testes are pubertal in size, or that testosterone remains elevated even when the 17OHP has been reduced toward normal. In girls central puberty is less often a problem, but breast development would be the main clue. Central precocious puberty is suppressed when appropriate by leuprolide.

As outlined above, recent additions to treatment to preserve growth include aromatase inhibition to slow bone maturation by reducing the amount of testosterone converted to estradiol, and use of blockers of estrogen for the same purpose.

Once adrenal suppression has been achieved, the patient needs stress steroid coverage as described above for significant illness or injury.

Other alleles result in even milder degrees of hyperandrogenism that may not even cause problems in males and may not be recognized until adolescence or later in females. Mild androgen effects in young women may include hirsutism, acne, or anovulation (which in turn can cause infertility). Testosterone levels in these women may be mildly elevated, or simply above average. These clinical features, of course, are those of polycystic ovary syndrome, and a small percentage of women with Polycystic Ovary Syndrome (PCOS) are found to have late-onset CAH when investigated.

Diagnosis of late-onset CAH may be suspected from a high 17α-hydroxyprogesterone level, but some cases are so mild that the elevation is only demonstrable after cosyntropin stimulation. Treatment may involve a combination of very low dose glucocorticoid to reduce adrenal androgen production and any of various agents to block the androgen effects and/or induce ovulation.

It was characterized in 1979 by Dr. Maria New. Prevalence has been described as 1 in 100 in certain populations.

In 1994, a 28-year-old man with EIS was reported. He was fully masculinized. At 204 cm, he had tall stature. His epiphyses were unfused, and there was evidence of still-occurring slow linear growth (for comparison, his height at 16 years of age was 178 cm). He also had markedly delayed skeletal maturation (bone age 15 years), a severely undermineralized skeleton, evidence of increased bone resorption, and very early-onset osteoporosis. The genitalia, testes, and prostate of the patient were all normal and of normal size/volume. The sperm count of the patient was normal (25 million/mL; normal, >20 million/mL), but his sperm viability was low (18%; normal, >50%), indicating some degree of infertility. The patient also had early-onset temporal hair loss. He reported no history of gender identity disorder, considered himself to have strong heterosexual interests, and had normal sexual function, including morning erections and nocturnal emissions.

Follicle-stimulating hormone and luteinizing hormone levels were considerably elevated (30–33 mIU/mL and 34–37 mIU/mL, respectively) and estradiol and estrone levels were markedly elevated (145 pg/mL and 119–272 pg/mL, respectively), while testosterone levels were normal (445 ng/dL). Sex hormone-binding globulin levels were mildly elevated (6.0–10.0 nmol/L), while thyroxine-binding globulin, corticosteroid-binding globulin, and prolactin levels were all normal. Osteocalcin and bone-specific alkaline phosphatase levels were both substantially elevated (18.7–21.6 ng/mL and 33.3–35.9 ng/mL, respectively).

Treatment with up to extremely high doses of ethinylestradiol (fourteen 100-µg patches per week) had no effect on any of his symptoms of hypoestrogenism, did not produce any estrogenic effects such as gynecomastia, and had no effect on any of his physiological parameters (e.g., hormone levels or bone parameters), suggesting a profile of complete estrogen insensitivity syndrome.

The symptoms of CAH vary depending upon the form of CAH and the sex of the patient. Symptoms can include:

Due to inadequate mineralocorticoids:

- vomiting due to salt-wasting leading to dehydration and death

Due to excess androgens:

- functional and average sized penis in cases involving extreme virilization (but no sperm)

- ambiguous genitalia, in some females, such that it can be initially difficult to identify external genitalia as "male" or "female".

- early pubic hair and rapid growth in childhood

- precocious puberty or failure of puberty to occur (sexual infantilism: absent or delayed puberty)

- excessive facial hair, virilization, and/or menstrual irregularity in adolescence

- infertility due to anovulation

- clitoromegaly, enlarged clitoris and shallow vagina

Due to insufficient androgens and estrogens:

- Undervirilization in XY males, which can result in apparently female external genitalia

- In females, hypogonadism can cause sexual infantilism or abnormal pubertal development, infertility, and other reproductive system abnormalities
