The primary management of cryptorchidism is watchful waiting, due to the high likelihood of self-resolution. Where this fails, a surgery, called orchiopexy, is effective if inguinal testes have not descended after 4–6 months. Surgery is often performed by a pediatric urologist or pediatric surgeon, but in many communities still by a general urologist or surgeon.

When the undescended testis is in the inguinal canal, hormonal therapy is sometimes attempted and very occasionally successful. The most commonly used hormone therapy is human chorionic gonadotropin (HCG). A series of hCG injections (10 injections over 5 weeks is common) is given and the status of the testis/testes is reassessed at the end. Although many trials have been published, the reported success rates range widely, from roughly 5 to 50%, probably reflecting the varying criteria for distinguishing retractile testes from low inguinal testes. Hormone treatment does have the occasional incidental benefits of allowing confirmation of Leydig cell responsiveness (proven by a rise of the testosterone by the end of the injections) or inducing additional growth of a small penis (via the testosterone rise). Some surgeons have reported facilitation of surgery, perhaps by enhancing the size, vascularity, or healing of the tissue. A newer hormonal intervention used in Europe is the use of GnRH analogs such as nafarelin or buserelin; the success rates and putative mechanism of action are similar to hCG, but some surgeons have combined the two treatments and reported higher descent rates. Limited evidence suggests that germ cell count is slightly better after hormone treatment; whether this translates into better sperm counts and fertility rates at maturity has not been established. The cost of either type of hormone treatment is less than that of surgery and the chance of complications at appropriate doses is minimal. Nevertheless, despite the potential advantages of a trial of hormonal therapy, many surgeons do not consider the success rates high enough to be worth the trouble since the surgery itself is usually simple and uncomplicated.

In cases where the testes are identified preoperatively in the inguinal canal, orchiopexy is often performed as an outpatient and has a very low complication rate. An incision is made over the inguinal canal. The testis with accompanying cord structure and blood supply is exposed, partially separated from the surrounding tissues ("mobilized"), and brought into the scrotum. It is sutured to the scrotal tissue or enclosed in a "subdartos pouch." The associated passage back into the inguinal canal, an inguinal hernia, is closed to prevent re-ascent.

In patients with intraabdominal maldescended testis, laparoscopy is useful to see for oneself the pelvic structures, position of the testis and decide upon surgery ( single or staged procedure ).

Surgery becomes more complicated if the blood supply is not ample and elastic enough to be stretched into the scrotum. In these cases, the supply may be divided, some vessels sacrificed with expectation of adequate collateral circulation. In the worst case, the testis must be "auto-transplanted" into the scrotum, with all connecting blood vessels cut and reconnected ("anastomosed").

When the testis is in the abdomen, the first stage of surgery is exploration to locate it, assess its viability, and determine the safest way to maintain or establish the blood supply. Multi-stage surgeries, or autotransplantation and anastomosis, are more often necessary in these situations. Just as often, intra-abdominal exploration discovers that the testis is non-existent ("vanished"), or dysplastic and not salvageable.

The principal major complication of all types of orchiopexy is a loss of the blood supply to the testis, resulting in loss of the testis due to ischemic atrophy or fibrosis.

Cryptorchidism is seen in all domestic animals, most commonly in stallions, boars and canines . The prevalence of this condition can vary depending on species and breed. Evidence of this condition is more likely in companion animals and swine than ruminants. The cause of this condition can vary from a combination of genetics, environment and epigenetics.

Treatment includes androgen (testosterone) supplementation to artificially initiate puberty, testicular prosthetic implantation, and psychological support. Gender Dysphoria may result in anorchic individuals who are assigned male at birth and raised as male despite lacking the necessary masculinizing hormones during prenatal, childhood, and adolescent development. Anorchic individuals who have a female identity may be administered estrogen alone in place of testosterone as no androgen blockers are necessary due to the lack of gonads.

Management of AIS is currently limited to symptomatic management; methods to correct a malfunctioning androgen receptor protein that result from an AR gene mutation are not currently available. Areas of management include sex assignment, genitoplasty, gonadectomy in relation to tumor risk, hormone replacement therapy, and genetic and psychological counseling.

The decision of whether to raise an individual with PAIS as a boy or a girl may not be obvious; grades 3 and 4 in particular present with a phenotype that may be difficult to classify as primarily male or female, and some will be incapable of virilization at puberty. Parents of an affected newborn should seek immediate help at a center with an experienced multidisciplinary team, and should avoid gender assignment beforehand. Gender assignment should thereafter be expeditiously decided; current guidelines advise against waiting for the child to decide for his / herself. Key considerations involved in assigning gender include the appearance of the genitalia, the extent to which the child can virilize at puberty, surgical options and the postoperative sexual function of the genitalia, genitoplasty complexity, potential for fertility, and the projected gender identity of the child. The majority of individuals with PAIS are raised male.

Virilization capacity can be assessed by measuring the response to a trial of exogenous androgens; some studies have measured the growth of the phallus in response to exogenous testosterone or dihydrotestosterone, while others have measured the change in sex hormone binding globulin (SHBG) in response to the artificial androgen stanozolol to assess androgen sensitivity. Some experts have cautioned that it remains to be proved that a good response to exogenous androgens in neonates is a good predictor of androgen response at puberty. If a mutation in the AR gene is found, it is important to determine whether the mutation is inherited or de novo (i.e. a somatic mutation); a certain amount of the wild-type androgen receptor will be present in cases of somatic mutation, which can induce virilization at puberty. A genital skin fibroblast study and a human chorionic gonadotropin (hCG) stimulation test may also provide information helpful in the assessment of virilization capacity.

Psychosexual development is influenced by many factors, including the timing, amount, and type of androgen exposure, receptor functionality, and environment, and is thus difficult to predict. Gender identity begins to develop before 3 years of age, although the earliest age at which it can be reliably assessed has yet to be determined. Approximately 25% of individuals with PAIS are dissatisfied with their assigned gender, regardless of being raised as male or female. One study reports that 46,XY individuals born with micropenis and no hypospadias are better off being raised male, despite the success of some being raised female. Studies involving the more ambiguous phenotypic forms of PAIS are less decisive. Homosexuality with respect to assigned gender and atypical gender role behavior are known to occur more frequently in individual with PAIS, and may occur with or without gender dysphoria; neither should be interpreted as an indication of incorrect gender assignment. If an affected child does express feelings of gender dysphoria, the opportunity to explore such feelings with a psychologist experienced in treating intersex conditions should be accommodated. If feelings of gender dysphoria persist, gender reassignment should be initiated, possibly with the aid of a specialist in the field.

Anorchia (or anorchism) is an XY disorder of sex development in which individuals have both testes absent at birth. Within a few weeks of fertilization, the embryo develops rudimentary gonads (testes), which produce hormones responsible for the development of the reproductive system. If the testes fail to develop within eight weeks, the baby will develop female genitalia (see Swyer syndrome). If the testes begin to develop but are lost or cease to function between eight and 10 weeks, the baby will have ambiguous genitalia when it is born. However, if the testes are lost after 14 weeks, the baby will have partial male genitalia with the notable absence of gonads.

Tests include observable lack of testes, low testosterone levels (typical female levels), elevated follicle stimulating hormone and luteinizing hormone levels, XY karyotype, ultrasound or magnetic resonance imaging showing absent gonadal tissue, low bone density, low anti-Müllerian hormone levels, and surgical exploration for evidence of male gonadal tissue.

Treatment of HH is usually with hormone replacement therapy, consisting of androgen and estrogen administration in males and females, respectively.

Hypergonadotropic hypogonadism (HH), also known as primary or peripheral/gonadal hypogonadism, is a condition which is characterized by hypogonadism due to an impaired response of the gonads to the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and in turn a lack of sex steroid production and elevated gonadotropin levels (as an attempt of compensation by the body). HH may present as either "congenital" or "acquired", but the majority of cases are of the former nature.
