Abstract

Infertility is common among couples, about one third of cases are the result of solely male factors, and rarely abnormalities of genetic karyotypes are the root cause. Individuals with a 45X,/46,XY mosaiscism are rare in the literature and very few have fertile potential. We discuss a case of a 27-year-old male with known mixed gonadal dysgenesis, 50:50 split mosaiscism of 45,X/46,XY, presenting for evaluation of 1.5 year history of infertility. He demonstrated low volume non-obstructive azoospermia. Upon testicular biopsy, spermatozoa were extracted. These sperm were subjected to aneuploidy studies demonstrating 95.95% euploidy. The sperm were further assessed and placed in cryopreservation after being deemed sufficient for potential intracytoplasmic sperm injection. This is a unique case of viable sperm in a man with mixed gonadal dysgenesis, 45,X/46,XY mosaiscism.
