Based on discrepancy between high follicle stimulating hormone (FSH) level and normal ovarian reserve parameters, follicle stimulating hormone receptor (FSHR) mutation was screened. The patient was homozygous in exon 6 of the FSHR gene for the new variant c.479T > C and predicted to result in an aminoacid substitution p.Ile160Thr. One year later, her anti-müllerian hormone (AMH) level inexplicably decreased. Oocyte vitrification was thus offered for fertility preservation. After 17 days of recombinant follicle stimulating hormone (recFSH) (900 IU daily), no follicular growth was seen and estradiol levels remained low. In vitro maturation (IVM) was then suggested. Ten oocytes were successfully vitrified.展开更多
