Abstract
PROBLEM: We report on a successful ovarian stimulation and pregnancy in a patient with 'resistant ovary syndrome' (ROS) and antigonadotrophin antibodies. ROS is characterized by high endogenous gonadotrophins, low estradiol, normal ovarian antral follicle counts and normal antimuellerian hormone values. METHOD OF STUDY: After cyclical hormone treatment, downregulation with GnRH analogue and ICSI procedure followed. Granulosa cells were treated with LH, FSH or hMG and expression of receptors for FSH, LH, oestrogen receptor beta (ERb) and progesterone receptor A (PR-A) was determined. Serum of the patient was analysed for antibodies directed against hMG. RESULTS: After fertilization of ten metaphase II oocytes and transfer of two blastocysts, a singleton pregnancy was established. Stimulation of granulosa cells with FSH, LH and hMG upregulated ERb and PR-A. Dot blot analysis showed strong reactivity with hMG but not with recFSH. CONCLUSION: This patient with normal expression of gonadotrophin receptors showed antibodies directed to hMG but not to recFSH.
