Persistent oligonecrozoospermia after asymptomatic SARS-CoV-2 infection. A case report and literature review.

COVID-19 is known to have deleterious effects on different systems such as the respiratory, cardiovascular, central nervous, and gastrointestinal. However, conflicting data about the possible implications for male reproductive health and fertility have been reported. In addition, the long-term consequences of SARS-CoV-2 infection remain unclear. Herein, we report a case of a 42-year-old man with no known co-morbidities and normal baseline semen quality, who subsequently suffered an asymptomatic SARS-CoV-2 infection. Shortly after, the patient developed sudden oligoasthenozoospermia, even reaching azoospermia, which gradually evolved into persistent severe oligonecrozoospermia, accompanied by semen inflammation and oxidative stress. Remarkably, the latter occurred in the absence of urogenital infections, hormonal imbalances, tissue/organ obstruction/damage, medication or drug treatment, smoking, or exposure to toxins/pollutants, radiation, or high temperature. This case constitutes valuable clinical evidence that adds to the current knowledge in the field and highlights the need for further and longer follow-up studies to better understand the putative long-term consequences of SARS-CoV-2 infection on male fertility.

[Clinical and evolutionary characteristics of incidental pituitary adenomas: retrospective multicenter study]. / Características clínicas y evolutivas de adenomas hipofisarios incidentales: estudio multicéntrico retrospectivo.

INTRODUCTION: Pituitary incidentalomas (PIs) are lesions found incidentally in the pituitary on imaging performed for reasons unrelated to pituitary disease. METHODS: A cross-sectional, retrospective and descriptive study was carried out with the aim of analyzing the clinical and evolutionary characteristics of a population of patients with PIs in the city of Córdoba. RESULTS: A total of 67 patients were included, 67% female, with a median age at diagnosis of 44 years. Among the reasons that led to requesting the first image, chronic or recurrent headache was the most prevalent (34%). The median tumor size was 12 mm. Fifty-eight percent were macroincidentalomas. Men had significantly larger lesions (p = 0.04). At diagnosis, including both sexes, 30% showed extrasellar extension and 45% invasion of the cavernous sinuses. Neuro-ophthalmological compromise was detected in 21%. A positive correlation was found between age at diagnosis and tumor size (r= +0.31, p = 0.001). Ninety-one percent were non-functioning tumors and at presentation, 21% of patients had one or more hormonal deficiencies. Of the total, 26% required surgery. Most of those who continued without treatment showed no change in tumor size at the end of follow-up (median 42 months). CONCLUSION: We highlight the high frequency of macroincidentalomas in our series, with visual field defects and hypopituitarism being frequent at diagnosis. Although most non-operated PIs remained stable, there was a high frequency of clinically significant lesions.

Introducción: Los incidentalomas hipofisarios (IH) son lesiones halladas fortuitamente en la hipófisis mediante imágenes realizadas por motivos no relacionados con enfermedad hipofisaria. Métodos: Se realizó un estudio transversal, retrospectivo y descriptivo con el objetivo de analizar las características clínicas y evolutivas de una población de pacientes portadores de IH en la ciudad de Córdoba. Resultados: Se incluyeron 67 pacientes, 67% del sexo femenino, con una mediana de edad al diagnóstico de 44 años. Entre los motivos que llevaron a solicitar la primera imagen, la cefalea crónica o recurrente fue el más prevalente (34%). La mediana del tamaño tumoral fue de 12 mm. El 58% fueron macroincidentalomas. Los hombres tuvieron lesiones significativamente más grandes (p = 0.04). Al diagnóstico, considerando ambos sexos, el 30% evidenció extensión extraselar y el 45% invasión a senos cavernosos. Se detectó compromiso neurooftalmológico en el 21%. Se halló correlación positiva entre la edad al momento del diagnóstico y el tamaño tumoral (r = +0.31, p = 0.001). El 91% fueron tumores no funcionantes y en su presentación, el 21% de los pacientes presentaron una o más deficiencias hormonales. El 26% del total requirió cirugía. La mayoría de aquellos que continuaron sin tratamiento no evidenciaron cambios en el tamaño tumoral al final del seguimiento (mediana 42 meses). Conclusión: Destacamos la elevada frecuencia de macroincidentalomas en nuestra serie, siendo los defectos del campo visual y el hipopituitarismo frecuentes al diagnóstico. Si bien la mayoría de los IH no operados permanecieron estables, existió una alta frecuencia de lesiones clínicamente significativas.

Enfermedad de Cushing en el embarazo y uso de cabergolina.

Introducción: La enfermedad de Cushing (EC) es rara durante el embarazo y se asocia con complicaciones maternas y fetales significativas. El objetivo fue reportar el caso de una paciente con EC que logró embarazo y parto sin complicaciones tras el tratamiento con dosis bajas de cabergolina. Métodos: Mujer de 29 años con diagnóstico de EC (macroadenoma secretor de ACTH que produce desplazamiento del quiasma óptico, infiltra el seno cavernoso derecho y engloba la arteria carótida interna). Se somete a cirugía transesfenoidal con resección tumoral incompleta. Luego de un año de estabilidad clínica, reaparecen los síntomas por lo que se instaura tratamiento médico con cabergolina. Durante el tratamiento la paciente concibe embarazo y se suspende la medicación. Resultados: En el primer trimestre, los parámetros clínicos y bioquímicos indican EC activa, por lo que se decide reinstaurar Cabergolina a dosis bajas durante el resto de la gestación. Con el agonista dopaminérgico se alcanza normalizar parámetros clínicos y de laboratorio y la paciente dio a luz una niña sana a las 38 semanas, dentro de percentiles normales y sin complicaciones. Conclusión: El embarazo es un evento raro en pacientes con EC. Sin embargo, las consecuencias de la exposición materno-fetal al hipercortisolismo pueden ser graves. Nuestra experiencia con el uso de cabergolina a dosis bajas en una embarazada con EC, aporta datos favorables a los escasos reportes bibliográficos existentes, sumando evidencia sobre el perfil de seguridad del fármaco en esta población de pacientes.

Principales disruptores endocrinos vinculados con salud reproductiva femenina: bases biológicas de su asociación / Main endocrine disruptors related to female reproductive health: biological basis of their association

Resumen Se denominan disruptores endocrinos (DEs) a aquellas sustancias químicas capaces de interferir con la homeostasis hormonal, alterando la síntesis, función, almacenamiento y/o metabolismo de las hormonas. Estas sustancias se encuentran en el ambiente y en una amplia variedad de productos de uso diario, por lo que la exposición humana es permanente. Experimentos con animales han confirmado la capacidad de los DEs para inducir desórdenes reproductivos, por lo que se ha sugerido que podrían ser un factor importante como causa de subfertilidad humana. El bisfenol A, los ftalatos y los compuestos orgánicos persistentes son tres tipos de DEs presentes en el medio ambiente y asociados con alteraciones reproductivas. Consultando las bases de datos MEDLINE y PubMed, en la presente revisión, se reúne bibliografía de los últimos 20 años donde se evalúan los efectos provocados por la exposición a los DEs mencionados en mujeres durante la vida adulta. Se resumen los efectos sobre marcadores de reserva ovárica y los resultados de tratamientos de fertilización in vitro. Por otro lado, se evalúa la evidencia a nivel molecular de los efectos provocados por los DEs sobre la fisiología reproductiva en estudios in vitro e in vivo.

Abstract Endocrine disruptors (EDs) are those chemical substances capable of interfering with hormonal homeostasis, altering the synthesis, function, storage and / or metabolism of hormones. These substances are found in the environment and in a wide variety of products for daily use, so human exposure is permanent. Animal experiments have confirmed the capacity of EDs to induce reproductive disorders, which is why it has been suggested that they could be an important factor in causing human subfertility. Bisphenol A, phthalates and persistent organic compounds are three types of EDs present in the environment and associated with reproductive disorders. Consulting the MEDLINE and PubMed databases, in this review, a bibliography of the last 20 years is gathered where the effects caused by exposure to the mentioned EDs in women during adult life are evaluated. The effects on ovarian reserve markers and the results of in vitro fertilization treatments are summarized. On the other hand, the evidence at the molecular level of the effects caused by EDs on reproductive physiology is evaluated in in vitro and in vivo studies.

Clitoromegaly due to an epidermal inclusion cyst: A case report.

Background: Clitoromegaly is often a sign of androgen excess; however, non-hormonal causes must be ruled out. We report the case of an adolescent with isolated clitoromegaly without clinical or biochemical evidence of hyperandrogenism. Case: A 16-year-old female was referred due to a clitoromegaly of 12 months of evolution. Examination of the pubic region revealed normal female genitalia with an enlarged clitoris, 4 cm long and 2.5 cm wide. The clitoris was painless, soft on palpation, and mobile over deeper layers. There were no signs of virilization, and the patient did not report dysuria or difficulties with sexual intercourse. Her medical record was also unremarkable, with no female circumcision, family history of birth defects, or genital abnormalities. Hormone profile blood tests were normal. Pelvic ultrasound examination was normal, but a high-resolution scan with a linear transducer confirmed the presence of a cyst, lying anterior to the clitoral body and glans. The cyst was surgically removed with special care to preserve the clitoral neurovasculature. The pathological report disclosed an epidermoid clitoral cyst. The patient described emotional well-being, satisfactory sexual function, and no discomfort after a year of follow-up. Conclusion: Epidermal clitoral cysts represent an unusual cause of clitoromegaly. These cysts should be ruled out as a differential diagnosis after an exhaustive semiological and endocrinological examination.

Favorable outcome of SARS-CoV-2 infection in a patient with pituitary insufficiency.

BACKGROUND: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) outbreak originated in Wuhan (China) rapidly turned into a pandemic. Due to a national compulsive decree of quarantine, office visits for chronic disease control were delay. Hypopituitarism includes all clinical conditions that result in partial or complete failure of the pituitary gland's ability to secrete hormones. Pituitary insufficiency per se has been associated with an increase in both morbidity and mortality, particularly due to cardiovascular disease, which is an important risk factor for COVID-19 disease severity. OBJECTIVE: To report the first case of SARS-CoV-2 infection in a patient with hypopituitarism, discuss the implications of the treatments the patient was taking and grade up the value of telemedicine in the present scenario. METHODS: Report of the clinical record of a patient with hypopituitarism and infection with SARS-CoV-2. RESULTS: During the span of the infection, the patient remained on the same hormonal therapeutic scheme (thyroid, gonadal and adrenal axis). The dose of hydrocortisone was not changed during the course of the infection as she was asymptomatic. We use telemedicine to control and advise her on the treatment. CONCLUSION: Health care professionals should carefully follow up on the evolution of patients with hypopituitarism to provide them a safer outcome. The use of telemedicine as a methodology for selected patients acquires relevance in the present epidemiological context.

[Surgical treatment in acromegaly: experience in Córdoba]. / Tratamiento quirúrgico en acromegalia: experiencia en Córdoba

Introduction: Acromegaly prevalence is 35-70 / million. Transsphenoidal surgery is the first-line treatment, with a remission rate of 80% for microadenomas and 50% for macroadenomas. Our aim was to evaluate the surgical results in Córdoba and determine predictive remission factors due to the lack of records. Methods: Retrospective-descriptive study of patients with surgery as the first therapeutic line. Remission criteria: IGF1 normalization for age/sex, with GH ≤1.0 g/L. Test X2 and Fisher's exact test with p<0.05. Results: 38 patients were included: 61% women and 39% men; Average age 45 years. Most frequent chief complaint: headache and acral growth (26%), visual disturbances (20%). Macroadenomas were the 84% of the tumors. Of 37 patients, 54% underwent microscopic surgery, 38% endoscopic and 8% transcranial. The 29% of patients showed post-operative complications and diabetes insipidus was the most frequent (10%). The percentage of them was: 33% transcranial surgery, 29% endoscopic and 25% microscopic (p = 0.557). The biochemical remission at 6 months was 34% and at 12 months 55% (p= 0.0001). No significant differences between the endoscopic and microscopic approach (p = 0.071). Of 36 patients, 31% showed complete tumor resection. The subjective clinical improvement was 88%. There weren´t predictive remission factors with significant differences. Conclusion: The surgical biochemical remission was similar to the bibliography. We didn´t find predictive remission factors but a larger number of patients could modify these results.

Introducción: La acromegalia tiene una prevalencia de 35-70/millón. La cirugía transesfenoidal es el tratamiento de elección, siendo la tasa de remisión del 80% en microadenomas y 50% en macroadenomas. Debido a la falta de registros, nos propusimos evaluar los resultados quirúrgicos en Córdoba y determinar factores predictivos de remisión. Métodos: Estudio retrospectivo-descriptivo de pacientes con cirugía como primera línea terapéutica. Criterios de remisión: normalización de IGF1 para edad/sexo, con GH ≤1,0 g/L.Test X2 y test exacto de Fisher y p<0,05. Resultados: Se incluyeron 38 pacientes: 61% mujeres y 39% hombres; edad promedio 45 años. Motivos de consulta más frecuentes: cefalea y crecimiento acral (26%), alteraciones visuales (20%). El 84% de los tumores fueron macroadenomas. De 37 pacientes, 54% se sometieron a cirugía microscópica, 38% endoscópica y 8% transcraneal. El 29% evidenció complicaciones postquirúrgicas, siendo la diabetes insípida la más frecuente (10%). El porcentaje de las mismas fue: cirugía transcraneal el 33%, endoscópica 29% y microscópica 25% (p= 0,557). La remisión bioquímica a los 6 meses fue de 34% y a los 12 meses 55% (p=0,0001). Sin diferencias significativas entre la vía endoscópica y microscópica (p=0,071). De 36 pacientes el 31% evidenció resección tumoral completa. La mejoría clínica subjetiva fue del 88%. No hubo factores predictivos de remisión bioquímica estadísticamente significativos. Conclusión: La remisión bioquímica con la cirugía fue similar a la bibliografía. No encontramos factores predictivos de remisión pero un número mayor de casos podría modificar estos resultados.

Pregnancy outcomes in women with polycystic ovary syndrome in two Latin American populations.

Pregnancy complications and obstetric outcomes were compared in 80 Chilean (PPCOSCh) and 70 Argentinian (PPCOSAr) pregnant women. Reference groups of Chilean and Argentinian normal pregnant women from the same antenatal care units were also compared. PPCOSCh showed a higher prevalence of gestational diabetes mellitus (GDM) (OR, 2.28, 95% CI: 1.08-4.77, p = .030) and a lower prevalence of pregnancy-induced hypertension (PIH) (OR, 0.20, 95% CI: 0.07-0.54, p = .001) compared to PPCOSAr. In the normal pregnant groups, the prevalence of PIH was lower in Chilean women compared to Argentinian women (OR, 0.24, 95% CI: 0.10-0.62, p = .001). Similar to the pattern observed in the normal populations, newborns from PPCOSCh had higher birth weight and length compared with the newborns of PPCOSAr (p = .006 and .014, respectively). In conclusion, differences in pregnancy complications and obstetric outcomes between Chilean and Argentinian pregnant women with PCOS could be determined by ethnic diversity together with environmental factors of both populations. Impact Statement What is already known on this subject: The reproductive and metabolic phenotypes of women with polycystic ovary syndrome vary between different populations, which could significantly influence the obstetric and neonatal outcomes in this syndrome. What the results of this study add: Pregnant women with PCOS from two Latin American countries (Chile and Argentina) exhibit differences in the prevalence of gestational diabetes and pregnancy-induced hypertension, and in the birth weight of their newborns. What the implications are of these findings for clinical practice and/or further research: Ethnic diversity together with environmental factors are fundamental elements that must be considered in the management of pregnant women with PCOS.

[Polycystic ovary sindrome: impact on reproductive and maternal fetal health]. / Síndrome de ovario poliquistico: impacto en la salud reproductiva y materno infantil.

UNLABELLED: Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism (H), oligo-anovulation (O) and / or polycystic ovaries (P). There is currently little information on perinatal complications. OBJECTIVE: to investigate obstetric and neonatal characteristics of women with PCOS in our population. MATERIAL AND METHODS: we studied 87 pregnant women with PCOS (categorized in four phenotypes according Rotterdam Consensus: A (H + O + P) n = 53; B (H + O) n = 9; C (H + P) n = 16 and D (O + P) n = 9) and 96 without PCOS (control). We analyzed clinical and biochemical features (age, anthropometry hirsutism, acanthosis nigricans, OGTT, insulin, lipid profile, androgen and gonadotropins) during preconception, (weight gain, blood pressure, OGTT) through gestation and occurrence of perinatal complications. RESULTS: we found no differences in age (29.4 ± 4 and 28.7 ± 5 years) and body mass index (28.2 ± 6 and 27.8 ± 6 kg / m2) in both groups; while patients with PCOS had higher waist circumference, blood pressure and acanthosis nigricans versus control. Despite similar weight gain, patients with PCOS had higher percentage of perinatal complications. In the A phenotype RR for perinatal adverse outcomes was 2.37 (95%CI: 1.67-3.36, p <0.001). The HOMA-IR index preconception and fasting glucose during pregnancy were the predictors for these complications (p=0.01). CONCLUSION: patients with PCOS have a higher risk for complications during pregnancy and newborns more frequently have low weight or macrosomy. A careful history can recognize patients with higher perinatal risk to develop complications.

[Update on endocrinology: management of prolactinomas during pregnancy]. / Actualización en endocrinología: manejo de las prolactinomas durante la gestación.

UNLABELLED: The prolactinomas are the most common functioning pituitary tumors. The hyperprolactinemia is associated with anovulation and infertility. OBJECTIVES: a) describe the relationship between hyperprolactinemia and fertility, b) review the results of the use of dopamine agonists during pregnancy and embryo-fetal development and c) review the therapeutic management in micro and macroprolactinomas during pregnancy. CONTENT: Medical therapy with dopamine agonists is the best treatment for prolactinomas of any size or invasiveness and restores ovulatory cycles in 80-90 % of patients. Cabergoline currently suggested rather than bromocriptine due to their excellent tolerability and long half-life. In general, it is recommended that fetal exposure to all drugs be limited to as short a period as possible. In the absence of menstrual period, the drug should be discontinued and confirm pregnancy. CONCLUSION: Both, bromocriptine and cabergoline, showed no evidence of obstetric and neonatal complications; however, experience with bromocriptine is higher. The patients with macroprolactinomas should be monitored clinically and evaluate the symptoms related to increased tumor size. If growth in the adenoma is suspected, nuclear magnetic resonance and neuro-ophthalmologic examination should be performed. In microprolactinomas the ophthalmologic examination is no formal indication. There is evidence that breastfeeding no increased risk for tumor growth.

Los prolactinomas son los tumores hipofisarios funcionantes más comunes. La hiperprolactinemia que generan se asocia con anovulación e infertilidad. OBJETIVOS: a) describir la relación entre hiperprolactinemia y fertilidad, b) revisar los resultados del uso de agonistas dopaminérgicos durante el embarazo y el desarrollo embriofetal y c) actualizar el manejo terapéutiterapéutico en micro y macroprolactinomas durante la gestación. CONTENIDO: Los agonistas dopaminérgicos son el tratamiento de primera línea para prolactinomas de cualquier tamaño o grado de invasión y restauran los ciclos ovulatorios en el 80 a 90 % de las pacientes. La cabergolina se sugiere actualmente en lugar de bromocriptina, debido a su excelente tolerabilidad y prolongada vida media. Se aconseja que la exposición fetal a todos los medicamentos sea lo más limitada posible. Ante la ausencia del período menstrual debe suspenderse el fármaco y confirmar el embarazo. CONCLUSION: Tanto bromocriptina como cabergolina no mostraron evidencia de complicaciones obstétricas ni neonatales, sin embargo, la experiencia con bromocriptina es mayor. Las pacientes con macroprolactinomas deben ser controladas clínicamente y evaluar sintomatología relacionada con el aumento del tamaño tumoral. Si se sospecha crecimiento del adenoma, debe solicitarse resonancia magnética nuclear y examen neuro-oftalmológico. En microprolactinomas la campimetría no es una indicación formal. Hay evidencia de que la lactancia materna no presenta mayor riesgo para el crecimiento tumoral.

Hyperandrogenism produced by ovarian tumors in women at different life stages.

OBJECTIVE: to evaluate the different presentations of hyperandrogenism produced by ovarian tumors in women at different life stages DESIGN: case report. SETTING: academic institutions. PATIENT(S): 3 patients at different life stages, with increased androgen levels. INTERVENTION(S): review of hospital records. MAIN OUTCOME MEASURE(S): clinical and biochemical features, treatment and follow-up. RESULT(S): a 10 year-old girl with Leydig cell tumor presented with hyperandrogenemia, virilization and changes in social behavior. Another patient, at reproductive age, with a tumor>10 cm, presented with signs of virilization and abdominal mass, whose pathologic analysis disclosed a carcinoid tumor of the ovary associated with stromal hyperplasia. The third patient was a postmenopausal woman with severe alopecia, who presented a steroid cell tumor, rare at that age. CONCLUSION(S): the evaluation of women with signs and symptoms of virilization should include a detailed clinical record, thorough physical examination and an appropriate hormonal dosage, especially when images are inconclusive.

Objetivo: evaluar las diferentes manifestaciones del hiperandrogenismo tumoral de origen ovárico en distintos grupos etarios. Diseño: reporte de casos.Lugar de trabajo: centros académicos.Pacientes: son reportadas tres pacientes con exceso de andrógenos. Resultados: describimos una paciente de 10 años con hiperandrogenemia y signos de masculinización secundarios a un tumor de células de Leydig; otra paciente, en edad fértil, con un tumor carcinoide de ovario asociado a hiperplasia estromal que se manifestó con signos de masa abdominal y de virilización. El tercer caso una mujer, en etapa postmenopáusica con alopecia severa, tenía un tumor de células esteroideas, raro en este grupo etario. onclusión: la evaluación de una mujer con signos y síntomas de virilización debe incluir una detallada historia clínica, examen físico y apropiados dosajes hormonales, especialmente si existe dificultad en establecer su origen cuando los estudios imagenológicos son normales.

Metabolic profile of the different phenotypes of polycystic ovary syndrome in two Latin American populations.

OBJECTIVE: To evaluate the metabolic profile of Chilean and Argentinian women with polycystic ovary syndrome (PCOS) according to the Rotterdam criteria. DESIGN: Observational cross-sectional study. SETTING: Academic centers. PATIENT(S): Women with PCOS, aged 18-39 years: 220 Chilean (PCOSCh) and 206 Argentinian (PCOSAr). INTERVENTION(S): Physical examination, fasting blood samples for androgens, gonadotropins, metabolic parameters, and a transvaginal ultrasound. MAIN OUTCOME MEASURE(S): Comparative analysis of the metabolic profile in both populations divided into four phenotypes. RESULT(S): The distribution of the different phenotypes was different in both populations. PCOSCh women showed a higher body mass index and a higher percentage of metabolic syndrome in all phenotypes compared with the PCOSAr women. The PCOSAr women exhibited a statistically significantly higher diastolic blood pressure in phenotypes A, B, and C and a higher percentage of hypertension in phenotypes A and D compared with the PCOSCh women. CONCLUSION(S): The data show differences in the metabolic profile of both populations. PCOSCh women presented with greater metabolic alterations such as dysglycemia and dyslipidemia and a higher prevalence of metabolic syndrome, independent of the phenotype. The PCOSAr patients showed more elevated blood pressure. Ethnic diversity associated with environmental factors are fundamental elements in the analysis of the PCOS phenotypes.

[Polycystic ovary syndrome: physiopathology review]. / Síndrome de ovario poliquístico: revisión de su fisiopatogenia.

Polycystic ovary syndrome (PCOS), the most common gynecological endocrinopathy in women of reproductive age, is characterized by hyperandrogenism, chronic anovulation and /or polycystic ovaries. Although the cause of PCOS is still unknown, there are several hypotheses attempting to explain the primary defect; the most commonly accepted is insulin resistance. Due to its high prevalence, the patients have increased risk of developing metabolic and cardiovascular alterations. The compensatory hyperinsulinemia contributes to hyperandrogenism in different ways: by stimulating ovarian androgen synthesis and inhibiting hepatic production of sex hormone binding globulin. From the study of the intrauterine environment in recent years it has been suggested that PCOS may have an origin in utero associated with prenatal exposure to androgens. The aim of this paper is to review the main mechanisms proposed to cause the syndrome.

Although the cause of PCOS is still unknown, there are several hypotheses attempting to explain the primary defect; the most commonly accepted is insulin resistance. Due to its high prevalence, the patients have increased risk of developing metabolic and cardiovascular alterations. The compensatory hyperinsulinemia contributes to hyperandrogenism in different ways: by stimulating ovarian androgen synthesis and inhibiting hepatic production of sex hormone binding globulin. From the study of the intrauterine environment in recent years it has been suggested that PCOS may have an origin in utero associated with prenatal exposure to androgens. The aim of this paper is to review the main mechanisms proposed to cause the syndrome.
