Infertility is the major symptom of TFI and is generally defined as a woman under 35 who has not become pregnant after 12 months without the use of contraception. Twelve months is the lower reference limit for "Time to Pregnancy" (TTP) by the World Health Organization. When the inability to conceive is accompanied by signs and symptoms of pelvic inflammatory disease such as lower abdominal pain, TFI may be present. A history of pelvic inflammatory disease, the laproscopic evidence of scarring and a diagnosis of salpingitis supports the diagnosis.

Tubal factor infertility (TFI) is female infertility caused by diseases, obstructions, damage, scarring, congenital malformations or other factors which impede the descent of a fertilized or unfertilized ovum into the uterus through the Fallopian tubes and prevents a normal pregnancy and full term birth. Tubal factors cause 25-30% of infertility cases. Tubal factor is one complication of Chlamydia trachomatis infection in women.

Sexually transmitted Chlamydia and genital mycoplasma infections are preventable causes of infertility and negative pregnancy outcomes. When the infections progress and ascend, they can result in TFI. Infertility can have multiple possible causes and may not be recognized for years after a gonorrhea, Chlamydia or Mycoplasma infection has caused tubal damage, as the affected woman may not have attempted to become pregnant until years later.

Unexplained infertility is infertility that is idiopathic in the sense that its cause remains unknown even after an infertility work-up, usually including semen analysis in the man and assessment of ovulation and fallopian tubes in the woman.

Symptoms and signs in the newborn can be sepsis, abdominal mass, and respiratory distress. Other abdominopelvic or perineal congenital anomalies frequently prompt radiographic evaluation in the newborn, resulting in a diagnosis of coincident vaginal atresia. Symptoms for vaginal atresia include cyclical abdominal pain, the inability to start having menstrual cycles, a small pouch or dimple where a vaginal opening should be, and pelvic mass when the upper vagina becomes filled with menstrual blood. Signs and symptoms of vaginal atresia or vaginal agenesis can often go unnoticed in females until they reach the age of menstruation. Women may also experience some form of abdominal pain or cramping.

Vaginal atresia can sometimes be diagnosed by physical examination soon after birth. A child with vaginal atresia often has other congenital abnormalities and other tests such as x-ray and tests to evaluate the kidney are done. Findings in adolescents may include abdominal pain, difficulty voiding, and backache, but most present with amenorrhea. Difficulties with sexual intercourse can suggest atresia. In the event that the condition is not caught shortly after birth, vaginal atresia becomes more evident when no menstrual cycle is occurs. If vaginal atresia is suspected by the doctor, a blood test may also be request for any of the previously mentioned syndromes, a magnetic resonance imaging (MRI) test, or an ultrasound. A regular evaluation of children born with an imperforate anus or anorectal malformation should be paired with the assessment of the results from these tests.

The symptoms of pseudocyesis are similar to the symptoms of true pregnancy and are often hard to distinguish from it. Such natural signs as amenorrhoea, morning sickness, tender breasts, and weight gain may all be present. Many health care professionals can be deceived by the symptoms associated with pseudocyesis. Research shows that 18% of women with pseudocyesis were at one time diagnosed as pregnant by medical professionals.

The hallmark sign of pseudocyesis that is common to all cases is that the affected patient is convinced that she is pregnant.

Abdominal distension is the most common physical symptom of pseudocyesis (60–90%). The abdomen expands in the same manner as it does during pregnancy so that the affected woman looks pregnant. These symptoms often resolve under general anesthesia and the woman's abdomen returns to its normal size.

The second most common physical sign of pseudocyesis is menstrual irregularity (50–90%). Women are also reported to experience the sensation of fetal movements known as quickening, even though there is no fetus present (50–75%). Other common signs and symptoms include gastrointestinal symptoms, breast changes or secretions, labor pains, uterine enlargement, and softening of the cervix. One percent of women eventually experience false labor.

To be diagnosed as true pseudocyesis, the woman must actually believe that she is pregnant. When a woman intentionally and consciously feigns pregnancy, it is termed a simulated pregnancy.

Symptoms of pseudocyesis can also occur in men who have couvade syndrome.

Examples of functional problems of the reproductive system include:

- Impotence - The inability of a male to produce or maintain an erection.

- Hypogonadism - A lack of function of the gonads, in regards to either hormones or gamete production.

- Ectopic pregnancy - When a fertilized ovum is implanted in any tissue other than the uterine wall.

- Hypoactive sexual desire disorder - A low level of sexual desire and interest.

- Female sexual arousal disorder - A condition of decreased, insufficient, or absent lubrication in females during sexual activity

- Premature ejaculation - A lack of voluntary control over ejaculation.

- Dysmenorrhea - Is a medical condition of pain during menstruation that interferes with daily activities

False pregnancy, phantom pregnancy, or hysterical pregnancy—officially called pseudocyesis in humans and pseudopregnancy in other mammals—is the appearance of clinical or subclinical signs and symptoms associated with pregnancy when the organism is not actually pregnant. Clinically, false pregnancy is most common in veterinary medicine (particularly in dogs and mice). False pregnancy in humans is less common, and may sometimes be purely psychological. It is generally believed that false pregnancy is caused by changes in the endocrine system of the body, leading to the secretion of hormones that cause physical changes similar to those during pregnancy. Some men experience the same illnesses as a woman would experience while pregnant when their partner is pregnant (see Couvade syndrome), possibly caused by pheromones that increase estrogen, prolactin, and cortisol levels.

Symptoms in PID range from none to severe. If there are symptoms, then fever, cervical motion tenderness, lower abdominal pain, new or different discharge, painful intercourse, uterine tenderness, adnexal tenderness, or irregular menstruation may be noted.

Other complications include endometritis, salpingitis, tubo-ovarian abscess, pelvic peritonitis, periappendicitis, and perihepatitis.

Reproductive tract infection (RTI) areinfections that affect the reproductive tract, which is part of the Reproductive System. For females, reproductive tract infections can be in either the upper reproductive tract (fallopian tubes, ovary and uterus), and the lower reproductive tract (vagina, cervix and vulva); for males these infections are at the penis, testicles, urethra or the vas deferens. The three types of reproductive tract infections are endogenous infections, iatrogenic infections and the more commonly known sexually transmitted infections. Each has its own specific causes and symptoms, caused by a bacterium, virus, fungus or other organism. Some infections are easily treatable and can be cured, some are more difficult, and some are non curable such as AIDS and herpes.

PPSH usually consists of:

- a phallus midway in size between penis and clitoris,

- a chordee tethering it to the perineum,

- a urethral opening usually on the perineum (the hypospadias),

- and an incompletely closed urogenital opening, which resembles a small and shallow vagina.

Testes are often palpable in the scrotum or inguinal canals, and the karyotype is XY. In most cases there are no internal female structures such as a uterus or other Müllerian duct derivatives.

In unexplained infertility abnormalities are likely to be present but not detected by current methods. Possible problems could be that the egg is not released at the optimum time for fertilization, that it may not enter the fallopian tube, sperm may not be able to reach the egg, fertilization may fail to occur, transport of the zygote may be disturbed, or implantation fails. It is increasingly recognized that egg quality is of critical importance and women of advanced maternal age have eggs of reduced capacity for normal and successful fertilization. Also, polymorphisms in folate pathway genes could be one reason for fertility complications in some women with unexplained infertility. Aberrant reproductive immunology such as decreased maternal immune tolerance towards the embryo may also be a possible explanation. However, a growing body of evidence suggests that epigenetic modifications in sperm may be partially responsible.

Signs of a miscarriage include vaginal spotting, abdominal pain or cramping, and fluid or tissue passing from the vagina. Bleeding can be a symptom of miscarriage, but many women also have bleeding in early pregnancy and don't miscarry. Bleeding during pregnancy may be referred to as a threatened miscarriage. Of those who seek clinical treatment for bleeding during pregnancy, about half will miscarry. Miscarriage may be detected during an ultrasound exam, or through serial human chorionic gonadotropin (HCG) testing.

An individual with this condition is hormonally normal; that is, the person will enter puberty with development of secondary sexual characteristics including thelarche and adrenarche (pubic hair). The person's chromosome constellation will be 46,XX. At least one ovary is intact, if not both, and ovulation usually occurs. Typically, the vagina is shortened and intercourse may, in some cases, be difficult and painful. Medical examination supported by gynecologic ultrasonography demonstrates a complete or partial absence of the cervix, uterus, and vagina.

If there is no uterus, a person with MRKH cannot carry a pregnancy without intervention. It is possible for the person to have genetic offspring by in vitro fertilization (IVF) and surrogacy. Successful uterine transplant has been performed in limited numbers of patients, resulting in several live births, but the technique is not widespread or accessible to many women.

A person with MRKH typically discovers the condition when, during puberty years, the menstrual cycle does not start (primary amenorrhoea). Some find out earlier through surgeries for other conditions, such as a hernia.

The infection usually has its origin in the vagina and ascends to the Fallopian tube from there. Because the infection can spread via the lymph vessels, infection in one Fallopian tube usually leads to infection of the other.

Pelvic inflammatory disease or pelvic inflammatory disorder (PID) is an infection of the upper part of the female reproductive system namely the uterus, fallopian tubes, and ovaries, and inside of the pelvis. Often there may be no symptoms. Signs and symptoms, when present may include lower abdominal pain, vaginal discharge, fever, burning with urination, pain with sex, or irregular menstruation. Untreated PID can result in long term complications including infertility, ectopic pregnancy, chronic pelvic pain, and cancer.

The disease is caused by bacteria that spread from the vagina and cervix. Infections by "Neisseria gonorrhoeae" or "Chlamydia trachomatis" are present in 75 to 90 percent of cases. Often multiple different bacteria are involved. Without treatment about 10 percent of those with a chlamydial infection and 40 percent of those with a gonorrhea infection will develop PID. Risk factors are similar to those of sexually transmitted infections generally and include a high number of sexual partners and drug use. Vaginal douching may also increase the risk. The diagnosis is typically based on the presenting signs and symptoms. It is recommended that the disease be considered in all women of childbearing age who have lower abdominal pain. A definitive diagnosis of PID is made by finding pus involving the fallopian tubes during surgery. Ultrasound may also be useful in diagnosis.

Efforts to prevent the disease include not having sex or having few sexual partners and using condoms. Screening women at risk for chlamydial infection followed by treatment decreases the risk of PID. If the diagnosis is suspected, treatment is typically advised. Treating a woman's sexual partners should also occur. In those with mild or moderate symptoms a single injection of the antibiotic ceftriaxone along with two weeks of doxycycline and possibly metronidazole by mouth is recommended. For those who do not improve after three days or who have severe disease intravenous antibiotics should be used.

Globally about 106 million cases of chlamydia and 106 million cases of gonorrhea occurred in 2008. The number of cases of PID however, is not clear. It is estimated to affect about 1.5 percent of young women yearly. In the United States PID is estimated to affect about one million people yearly. A type of intrauterine device (IUD) known as the Dalkon shield led to increased rates of PID in the 1970s. Current IUDs are not associated with this problem after the first month.

Women with a luteoma of pregnancy typically don't show any symptoms. Only 36% of women actually show signs of masculinization. These signs include acne, the growth of dark hair (especially on the face), deepening of the voice, temporal balding, and clitoromegaly. An increase in testosterone levels in the mother doesn't necessarily mean masculinization will occur. During a normal pregnancy, the testosterone level will increase slightly in the first and second trimester, but doubles in the third trimester. The testosterone level also depends on the sex of the fetus; male fetuses cause a bigger increase in testosterone levels than female fetuses.

The symptoms and discomforts of pregnancy are those presentations and conditions that result from pregnancy but do not significantly interfere with activities of daily living or pose a threat to the health of the mother or baby. This is in contrast to pregnancy complications. Sometimes a symptom that is considered a discomfort can be considered a complication when it is more severe. For example, nausea (morning sickness) can be a discomfort, but if, in combination with significant vomiting it causes a water-electrolyte imbalance, it is a complication known as hyperemesis gravidarum.

Common symptoms and discomforts of pregnancy include:

- Tiredness.

- Constipation

- Pelvic girdle pain

- Back pain

- Braxton Hicks contractions. Occasional, irregular, and often painless contractions that occur several times per day.

- Edema (swelling). Common complaint in advancing pregnancy. Caused by compression of the inferior vena cava and pelvic veins by the uterus leads to increased hydrostatic pressure in lower extremities.

- Increased urinary frequency. A common complaint, caused by increased intravascular volume, elevated glomerular filtration rate, and compression of the bladder by the expanding uterus.

- Urinary tract infection

- Varicose veins. Common complaint caused by relaxation of the venous smooth muscle and increased intravascular pressure.

- Haemorrhoids (piles). Swollen veins at or inside the anal area. Caused by impaired venous return, straining associated with constipation, or increased intra-abdominal pressure in later pregnancy.

- Regurgitation, heartburn, and nausea.

- Stretch marks

- Breast tenderness is common during the first trimester, and is more common in women who are pregnant at a young age.

In addition, pregnancy may result in pregnancy complication such as deep vein thrombosis or worsening of an intercurrent disease in pregnancy.

The symptoms usually appear after a menstrual period. The most common are:

- Abnormal smell and colour of vaginal discharge

- Pain during ovulation

- Pain during sexual intercourse

- Pain coming and going during periods

- Abdominal pain

- Lower back pain

- Fever

- Nausea

- Vomiting

- Bloating

Pseudovaginal perineoscrotal hypospadias (PPSH) refers to a configuration of the external genitalia of an infant. In a sense, this configuration is roughly midway between normal male genitalia and normal female genitalia in structure and appearance. It is a relatively common form of genital ambiguity caused by undervirilization of genetic males due to several different intersex conditions.

Uterine prolapse is a form of female genital prolapse. It is also called pelvic organ prolapse or prolapse of the uterus (womb).

Risk factors for uterine prolapse include pregnancy, childbirth, chronic increases in intra-abdominal pressure such as lifting, coughing or straining, connective tissue conditions, and damage to or weakness of the muscles.

Treatment may be conservative or surgical and should be based upon patient symptoms and preference.

A luteoma is a tumor that occurs in the ovaries during pregnancy.

It is associated with an increase of sex hormones, primarily progesterone and testosterone. The size of the tumor can range from 1 to 25 cm in diameter, but is usually 6 to 10 cm in diameter and can grow throughout the duration of the pregnancy. However, luteomas are benign and resolve themselves after delivery. This type of tumor is rare with only about 200 documented cases; many of these cases were detected accidentally, so the actual rate of occurrence may be higher. The most obvious symptom of a luteoma is masculinization of the mother and the possible masculinization of the fetus. This occurs because of the release of testosterone by the luteoma. Testosterone is a sex hormone most abundant in men although small amounts are naturally present in women. Testosterone is responsible for the male characteristics such as deepening of the voice, growth of dark hair, and acne. While not life-threatening, the development of male characteristics associated with luteomas can cause visible changes in the mother and can have drastic effects on the formation of the fetus. Luteomas can cause the fetus to be born with an ambiguous sex, which, depending on how the parents prefer to raise the infant, may result in the parents choosing a sex for the fetus.

Luteomas can be associated with female pseudohermaphroditism.

Female infertility refers to infertility in female humans. It affects an estimated 48 million women with the highest prevalence of infertility affecting people in South Asia, Sub-Saharan Africa, North Africa/Middle East, and Central/Eastern Europe and Central Asia. Infertility is caused by many sources, including nutrition, diseases, and other malformations of the uterus. Infertility affects women from around the world, and the cultural and social stigma surrounding it varies.

Hyperemesis gravidarum is the presence of severe and persistent vomiting, causing dehydration and weight loss. It is more severe than the more common morning sickness and is estimated to affect 0.5–2.0% of pregnant women.

Miscarriage may occur for many reasons, not all of which can be identified. Risk factors are those things that increase the likelihood of having a miscarriage but don't necessarily cause a miscarriage. Up to 70 conditions, infections, medical procedures, lifestyle factors, occupational exposures, chemical exposure, and shift work are associated with increased risk for miscarriage. Some of these risks include endocrine, genetic, uterine, or hormonal abnormalities, reproductive tract infections, and tissue rejection caused by an autoimmune disorder.
