Gonadal dysfunction and infertility in kidney transplant patients receiving sirolimus.

Abstract:

:Sirolimus is an immunosupressor of the mammalian target of rapamycin inhibitors (mTOR-I) group. Recent studies have emphasized a potential impact of sirolimus on male gonadal function. We report our clinical experience with sirolimus-induced gonadal dysfunction and infertility in both male and female kidney transplant patients. Of the 170 kidney transplant patients, nine (5.3%) patients (six males and three females) were receiving sirolimus. Follow-up data for two male patients were not available. The one unmarried female patient developed amenorrhea post-transplantation and had resumption of her menstrual cycles after discontinuation of sirolimus. The remaining six married patients (four males and two females), who all had fathered or conceived children in the pre-transplantation period, developed gonadal dysfunction and infertility on average 5-12 months after transplantation. Sirolimus was discontinued in all four male patients with full recovery of the oligo/azospermia and restoration of fertility. Both married female patients developed amenorrhea post-transplantation. Sirolimus was discontinued in one female patient with resumption of her menstrual cycles. In this small population of patients treated with sirolimus, the prevalence rate of reversible gonadal dysfunction and infertility was significant in both males and females. Infertility secondary to sirolimus is under-diagnosed and should be studied further.
