OBJECTIVE: To report a case of Turner mosaicism with low oocyte maturity during ICSI.
DESIGN: Retrospective case report.
SETTING: Academic tertiary medical center.
PATIENT(S): A 28-year-old patient with 7-year history of primary unexplained infertility.
INTERVENTION(S): Four cycles of ICSI.
MAIN OUTCOME MEASURE(S): Oocyte quality; fertilization, cleavage, and implantation rates; and live births during ICSI cycles; as well as patient karyotype were obtained.
RESULT(S): Over four cycles of ICSI, 111 oocytes were harvested, a high follicular response, but 68% were immature (germinal vesicles or metaphase I). Additionally, seven embryos were transfered, but none implanted. Owing to this unusual response in a young healthy woman, maternal karyotype was performed, which demonstrated 17% Turner mosaicism.
CONCLUSION(S): This is, to our knowledge, the first reported case of excellent ovarian response but marked oocyte immaturity in a young woman with Turner mosaicism. The implications of sex chromosome aneuploidy on fertility and the significance of low oocyte maturity are discussed.
