A suspected poor responder to controlled ovarian stimulation (COS), with menopausal levels of follicular phase serum FSH, required coasting due to an excessive ovarian response. A 27 year old woman was referred to our Fertility Centre for ovum donation following repeated elevated, early follicular phase FSH levels (34.3, 27.1, 20.3 IU/l). Further investigations revealed the presence of antiovarian antibodies and a trial of COS, with the additional use of prednisolone, was proposed in view of her regular 28 day cycle. As 23 follicles were noted and an oestradiol level of 10 461 pmol/l following 7 days of stimulation with 450 IU of recombinant FSH per day, gonadotrophins were withheld for 9 days. Ten oocytes were retrieved and two grade I embryos were transferred. Pregnancy did not occur and she developed mild ovarian hyperstimulation syndrome. During a second cycle, multiple follicular development was again observed with an oestradiol level >13 200 pmol/l, despite a lower dose of gonadotrophin, and coasting was required for 4 days. Nineteen oocytes were collected, of which nine fertilized and cleaved. Two grade I embryos were replaced, leading to a singleton pregnancy. This patient subsequently had a vaginal delivery of a normal male baby at term. Young women with regular menstrual cycles and grossly elevated FSH levels may benefit from further investigation of autoantibodies and their ovarian response to exogenous gonadotrophins.
