Abstract: (81 Views)
Introduction: The mammalian Y chromosome is a vital sex-determining factor in mammals by encoding gonadal genes. However, there are some discordant conditions with the XY female chromosome, which can lead to their inclusion in the disorders of sex development group.
Case Report: The person under study is a 22-year-old woman for whom written consent was obtained, and all ethical procedures were followed. Herein, we report an extraordinarily fertile adolescent phenotypic mother with congenital XY abnormality who reared as female, spontaneous puberty with regular menstruation and two gestations. This condition was initially diagnosed using the karyotype technique and finally confirmed with the specialized Fluorescence in-situ hybridization technique. Finally, the quantitative fluorescent polymerase chain reaction technique was used for more certainty. Usually, the male genotype cannot be fertile; since this case is unique, various reasons are involved in its occurrence. One of these cases can be a bone marrow or blood transplant, but according to the study, the possible development of this disorder can be caused by the fetal period.
Conclusion: As the prior clinical history of the case report revealed that her twin brother died during her mother’s expectancies, it can be assumed that the blood supply between the two fetuses has been shared unevenly or that feto-fetal transfusion has occurred. This incident has caused her to become a chimera with XY karyotype.
