BACKGROUND: The 45,X/46,XY karyotype has been associated with mixed gonadal dysgenesis (MGD) and ovotesticular disorder of sex development (DSD). Our aim was to revise the diagnosis of ovotesticular DSD in two patients in the context of a retrospective study of 45,X/46,XY subjects with genital ambiguity. CASE PRESENTATION: Patient 1 had a left streak gonad; the right one was considered an ovotestis. Patient 2 had a right testis; the left gonad was considered an ovary...

46,XX disorders of sexual development (DSDs) occur rarely and result from disruptions of the genetic pathways underlying gonadal development and differentiation. We present a case of a young phenotypic male with 46,XX SRY-negative ovotesticular DSD resulting from a duplication upstream of SOX9 presenting with a painful testicular mass resulting from ovulation into an ovotestis. We present a literature review of ovulation in phenotypic men and discuss the role of SRY and SOX9 in testicular development, including the role of SOX9 upstream enhancer region duplication in female-to-male sex reversal...

Approximately 15% of couples are infertile. Male factors contribute to infertility in over 50% of cases. Identifiable genetic abnormalities contribute to 15%-20% of the most severe forms of male infertility, azoospermia. In this chapter, we explore known genetic causes of male infertility such as Klinefelter syndrome, XYY men, Kallmann syndrome, y-microdeletions, Robertsonian translocations, autosomal inversions, mixed gonadal dysgenesis, x-linked and autosomal gene mutations, and cystic fibrosis transmembrane conductance regulator abnormalities...

A case of a 45,X/46,XY boy with gonadal dysgenesis is presented. The patient showed hypospadias and right undescended testis. He underwent underwent repair surgery for hypospadias, right orchidopexy, and bilateral testicular biopsy. Testicular biopsy revealed no malignant finding. He was followed-up annually by scrotum palpation. When the patient grew up to 24 years old, he was diagnosed to have right testicular tumor. High orchiectomy revealed pT1 seminoma. The management of undescended testis in men with gonadal dysgenesis and disordered sexual development is discussed...

OBJECTIVE: Rare congenital conditions with incongruence of chromosomal, gonadal and phenotypic sex have been classified as differences/disorders of sex development (DSD). Included in DSD are conditions with diverse genetic aetiology, varying levels of prenatal androgen effects, phenotypes and, subsequently, different medical treatments. Quality of life (QoL) and psychological well-being are indicators of successful psychosocial adaptation to the conditions. We sought to investigate the HRQoL and psychological well-being in this population...

Mixed gonadal dysgenesis is a rare disorder of sex development associated with sex chromosome aneuploidy and mosaicism of the Y chromosome. It is characterized by a unilateral non-palpable (usually intra-abdominal) testis, a contralateral streak gonad and persistent mullerian structures. The clinical presentation can vary from a typical male to female phenotype including all degrees of cryptorchidism, labial fusion, clitoromegaly, epispadias and hypospadias. It is the second most common cause of ambiguous genitalia in the neonatal period...

INTRODUCTION: Disorders of sex development (DSD) are a heterogeneous group of complex conditions that can affect chromosomal, gonadal, and/or phenotypical sex. In addition to impacts on internal and external genitalia,these conditions can affect fertility potentialto various degrees. In this review we discuss fertility issues including gonadalpreservation and reproductive outcomes based on specific DSD conditions. METHODS AND MATERIALS: A systematic literature review was performed on Embase(™), PubMed(®), and Google Scholar(™) for disordersof sex development and infertility...

Transverse testicular ectopia (TTE) is a rare form of ectopic testis observed in boys with a normal 46, XY karyotype. TTE can be associated with persistent Müllerian duct syndrome or other genital anomalies such as hypospadias. However, TTE concomitant with both persistent Müllerian duct remnants and hypospadias has never been reported in the literature. A case of chromosomal disorders of sex development with TTE and persistent Müllerian duct remnants, which was initially presumed to represent mixed gonadal dysgenesis, is presented...

UNLABELLED: Mixed gonadal dysgenesis is characterised by unilateral chromosomal abnormality, which is probably the result of anaphase lag during mitosis. The 45, XO/46, XY karyotype is the most common form of mosaicism involving the Y chromosome. It is a rare clinical entity with a worldwide incidence of 1.5/10,000 live births. Its epidemiology in Sub-Saharan Africa is not known. This study reports experience in the management of 3 cases at the Yaounde Gynecologic-Obstetric and Paediatric Hospital...

Mixed gonadal dysgenesis (MGD) is a rare disorder of sexual development (DSD). A seven-year-old child with vagina and an elongated clitoris looking like a penile part of male external genitalia, presented in the Paediatric Surgery Department. Ultrasound of pelvis revealed a streak ovary on the right side and ovotestis on the left side. Uterus was not visualized. Karyotyping revealed 46, XY/45, XO genotype. Laparoscopic gonadectomy with vaginoplasty and the clitoral reduction was performed. A thorough histopathological examination of the specimen revealed structure of ovotestis-consisting of the ovary with Graafian follicles, fallopian tube, infantile testis with Leydig and Sertoli cells, epididymis, vas deference, and pampiniform plexus...

Swyer syndrome or pure gonadal dysgenesis 46, XY is a medical condition associated with 46 XY karyotype and primary amenorrhea in a phenotypic female. In this syndrome, there is an abnormality in testicular differentiation. Patients with disorders in sexual differentiation have an increased risk for development of genital malignancies. A 14-year-old female admitted with abdominal pain was diagnosed to have Swyer syndrome and a pelvic tumor after clinical and laboratory investigations. She underwent surgery, and the histology report revealed a mixed germ cell tumor in a dysgenetic gonad...

Turner syndrome is the most common chromosomal disorder in girls. Various phenotypic features show depending upon karyotype from normal female through ambiguous genitalia to male. Usually, Turner girls containing 45,X/46,XY mosaicism, or sex-determining region Y (SRY) gene may have mixed gonadal dysgenesis with various external sexual differentiation. We experienced a short statured 45,X Turner girl with normal external genitalia. Because SRY gene was positive, laparoscopic gonadectomy was performed. The dysgenetic gonads revealed bilateral ovotesticular tissues...
