Outcomes of Fertility Preservation Consults for Women at Risk for Primary Ovarian Insufficiency Due to History of Cancer Treatment or Mosaic Turner Syndrome.

Adolescents and young adults (AYAs) at risk of primary ovarian insufficiency (POI) often request fertility preservation consultation. We report consult/treatment outcomes for 21 cancer survivors and 3 mosaic Turner syndrome (TS) patients (mean age 21.6 at consult, 3 with POI). Ten AYAs (9 survivors, 1 mosaic TS) attempted ovarian stimulation; 4 cancelled for poor response. Of completed cycles, mean 3.8 mature oocytes were retrieved, with mean anti-Müllerian hormone 0.653 ng/mL. Ovarian stimulation for mosaic TS AYA and survivors is possible, even with diminished ovarian reserve. Further study is needed to establish guidelines for patient selection, treatment timing, and stimulation protocols. [ABSTRACT FROM AUTHOR]
