Sexuality and fertility desire in a large cohort of individuals with 46, XY differences in sex development

Abstract Objective: To analyze aspects of sexual life and fertility desire among 46, XY DSD people, including those who changed their gender. Methods: It is a cross-sectional study including 127 adults (> 16 years of age) with 46, XY DSD (83 females; 44 males) from a Single Brazilian Tertiary-Care Medical Center. Results: Sexual fantasies and masturbation were more frequent in 46, XY DSD males, whereas orgasm and sexual life satisfaction were similar in both genders. More 46, XY DSD men than women had a long-term romantic relationship. 46, XY DSD women with prenatal androgen exposure reported more fear of being romantically rejected. External genitalia appearance at birth did not impact the sexuality of 46, XY DSD women after surgical genital treatment had been completed. Overall, the sexual life was similar between 46, XY men assigned as males and those who changed to the male gender. Regarding sexual orientation, most self-reported as heterosexual (91% and 92% of women and men, respectively). The desire for fertility had a similar prevalence in both genders, but more women than men considered infertility a barrier to a long-term romantic relationship. Twelve individuals (7 males) had children; 10 out of 12 have adopted children. Conclusion: Fertility desire was shared among 46, XY DSD people, regardless of gender. Prenatal androgen exposure reduced the desire for motherhood in 46, XY women. 46, XY DSD people who changed from female to male gender presented similar sexual parameters as those assigned as males. Among females, virilized genitalia at birth did not affect sexuality once the surgical treatment is completed.

Clinical and genetic analysis of 46, XY partial gonadal dysgenesis caused by DHX37 mutation: One case report and literature review / 中华内分泌代谢杂志

One case of 46, XY partial gonadal dysgenesis due to a congenital defect of DEAH-box RNA helicase 37(DHX37) was reported. The clinical and genetic data of a boy who was admitted to the Department of Endocrinology and Metabolism, the First Affiliated Hospital of Henan University of Science and Technology due to ambiguous external genitalia in September 2020 were collected and analyzed. This 3-month-old male patient showed a micropenis, bilateral cryptorchidism, 46, XY karyotype, a decrease in testosterone, anti-Müllerian hormone, inhibin B, an increase in follicle stimulating hormone. Testis biopsy indicated gonadal dysgenesis. The proband harbored a de novo heterozygous mutation in the DHX37 gene c. 923G>A(p.Arg308Gln). DHX37 variants need to be considered for 46, XY gonadal dysgenesis.
