True hermaphroditism, otherwise referred to as ovotesticular disorder of sexual differentiation, is an uncommon genetic ailment in which an individual possesses both female and male internal reproductive organs, namely ovaries and testes.
Presentation
Patients with true hermaphroditism may be diagnosed during infancy or adolescence, depending on the extent of the deviation from the normal male or female phenotype that they exhibit. The spectrum of clinical presentation, focusing on the genital areas, varies greatly. Some individuals may manifest as normally female or male, but the vast majority display aberrantly shaped genitalia that cannot be easily categorized under one of the two sex categories [1] [2].
Newborns affected by true hermaphroditism have labioscrotal folds, which may contain a palpable mass, either testis or ovotestis; such a clinical finding is relevant to the disorder. An ovotestis is present in more than 60% of the cases and constitutes a combination of ovarian and testicular tissue, with the latter situated centrally and the former in a polar location [3].
True hermaphroditism is primarily diagnosed during adolescence, as the physical development process renders genital irregularities more prominent. Specifically, a male adolescent is expected to evince feminization, such as a feminine sexual hair pattern. Female patients manifest with virilization during puberty, including excessive facial hair, small-sized breasts, loss of female fat distribution and abnormal genitalia [4]; a vagina exists in a small number of patients and has a common urogenital sinus with the urethra. In female patients, if a uterus exists (a possibility that cannot be accurately defined), it is usually accompanied by complications, such as uterine hypoplasia, cervical atresia or hemiuterus. The patient may menstruate or have symptoms related to an outflow blockage. In the case of male victims, hypospadias with bifid scrotal folds is a frequent finding; chordee can also be encountered. Individuals who have undergone a male sex assignment surgery during infancy may manifest with abnormally large breasts during adolescence [5].

Workup
The complete workup involved in diagnosing true hermaphroditism entails cytogenetic studies, hormonal laboratory evaluation, imaging studies and laparotomy or laparoscopy.
Cytogenetics
The karyotype most commonly associated with true hermaphroditism is 46 XX, followed by 46 XY. Other, rarely occurring karyotypes include a 46 XY/46 XY mosaicism. Cytogenetic studies are further completed by fluorescent in situ hybridization for occult Y-DNA. The 46 XX karyotype is the predominant one in up to 9 out of 10 patients [6].
Laboratory studies
Patients with true hermaphroditism exhibit normal values of serum 17-hydroxyprogesterone; abnormal concentrations can direct the diagnosis towards congenital adrenal hyperplasia (CAH). Basal levels of testosterone, androstenedione, dehydroepiandrosterone sulfate and dihydrotestosterone (DHT) are also measured in order to reveal occult testicular tissue. After a 5-day administration of human chorionic gonadotropin, the aforementioned hormones are again measured; elevated testosterone levels indicate that testicular tissue is present. An equivalent test is carried out in order to discover ovarian tissue, in which elevated levels of estradiol following the administration of clomiphene citrate or gonadotrophin reveals the presence of female reproductive tissue. A genital skin biopsy can illustrate a potential androgen insensitivity.
The presence of gonads which cannot be decided from the clinical examination can be detected with the use of genital ultrasonography (US). A genitogram will help to define the margins of a potential uterus (should it exist). Presently, the abdominal US, a computerized tomography scan (CT) and magnetic resonance imaging (MRI) are powerful tools to discover internal reproductive organs.
True hermaphroditism can be diagnosed before birth, with the help of amniocentesis, if the fetus features a 46 XX/46 XY or 46 XX/47 XXY or a 46 XX karyotype [7]. Any patient affected by the disorder is considered male or female, depending on penile length [8].
Treatment

The treatment of patients is therefore becoming more individualized and less standardized. Hermaphroditism is a complex issue and the ideal treatment of the condition is not clear. [news-medical.net]

Prognosis
Prognosis With appropriate corrective surgery, the appearance of external genitalia may appear normal. However, other problems such as virilization may appear later in life. [encyclopedia.com]
The prognosis depends on the specific cause of intersex. With understanding, support, and appropriate treatment, overall outlook is excellent. [medlineplus.gov]
Etiology
The exact etiology of ODSD is unknown but is largely believed to be genetic based. Sex determining region on the Y chromosome (SRY) is responsible for testicular development in the male fetus. [lecturio.com]
The etiology and pathogenesis of the true hermaphroditism is completely unknown. This disease is not hereditary, as in all cases, brothers and sisters patients developed normally. [medicalency.com]
True hermaphroditism is a rare condition both in North American and Europe, but one of the more common etiologies of male sexual ambiguity. It is, in contrast, common in Africa, especially in South Africa. [humpath.com]

The high testosterone production did not prevent the appearance of a positive oestrogen-LH feedback. The relative peripheral insensitivity to testosterone, is, in some ways, inconsistent with the presence of receptors for androgens. [ncbi.nlm.nih.gov]
Its management involves surgical correction of the external genitalia and treatment with appropriate glucocorticoids to prevent the consequences of its deficiency and arrest rapid virilization. [sonoworld.com]
