Objective: Luteinizing hormone (LH) surge is important in the final maturation of the oocyte and in oocyte retrieval. The structural similarity of human chorionic gonadotropin (HCG) and LH allow its binding to HCG/LH receptor. So, we aimed to compare the efficacy of urinary HCG (uHCG) and recombinant HCG (rHCG) for induction of oocyte maturation, triggering ovulation and incidence of pregnancy through assessing the serum levels of estrogen, progesterone, and βHCG in infertile women undergoing intracytoplasmic sperm injection (ICSI) cycles.
Subjects and Methods: Eighty-one Egyptian females were recruited in this study including 71 infertile females undergoing ICSI and 10 apparently healthy females as a control group. The infertile female patients were classified based on the treatment used for triggering of mature follicles into 35 infertile females received 1000 IU uHCG and 36 infertile females received 500 g rHCG. Serum levels of basal follicle stimulating hormone (FSH) and LH, estrogen (E2), progesterone (P) and βHCG were measured at different times of menstrual cycle by ELISA methods.
Results: serum FSH and LH were similar in all the studied groups. Serum P level at day 5 embryo transfer and number of retrieved and mature oocytes were comparable in the rHCG and uHCG groups. While Serum P level at day oocyte pick up was significantly higher in rHCG group than in uHCG group. The successful pregnancy was higher in uHCG group than in rHCG group.
Conclusion: the uHCG more effective biochemical pregnancy rate more than rHCG. However, rHCG showed equivalent efficacy to uHCG in terms of serum P level at day 5 embryo transfer, the number of retrieved oocytes and mature oocytes in female patients undergoing ICSI. While rHCG increases the serum P level at day oocyte pick up to abnormal high level which may reduce the incidence of pregnancy in females received rHCG.

Key words: HCG; ICSI; Pregnancy; Progesterone; Recombinant; Urinary.
