Oocyte cryopreservation in mosaic Turner syndrome with polycystic ovaries

Abstract

Objective

To report a case of a patient with Turner syndrome (TS) mosaicism and polycystic ovarian syndrome (PCOS), who underwent successful ovarian stimulation, oocyte retrieval, and cryopreservation.

Design

Case report.

Subject(s)

A female patient with mosaic TS (45,X [24%]/46,XX [76%]) and a paternally inherited balanced reciprocal translocation t(2:6) diagnosed with PCOS.

Intervention(s)

Controlled ovarian stimulation, oocyte retrieval, and cryopreservation.

Main outcome measure(s)

Successful oocyte retrieval and cryopreservation.

Result(s)

We report an interesting case of a patient with TS mosaicism 45,X [24%]/46,XX [76%] and a paternally inherited t(2:6) balanced reciprocal translocation, who was diagnosed with PCOS on the basis of oligomenorrhea and ultrasound polycystic ovary morphology (antral follicle count of 17 and >20, left and right ovaries, respectively), underwent 2 cycles of ovarian stimulation, oocyte retrieval, and cryopreservation, resulting in 19 cryopreserved oocytes.

Conclusion(s)

Our case highlights the importance of early counseling regarding fertility options in patients with mosaic TS and the need for careful monitoring of ovarian reserve during this process, which could be done by measuring the anti-müllerian hormone or antral follicle count. It also underscores the possibility of women with mosaic TS being affected by PCOS.
