Abstract  
Purpose: The aim of the study was to assess the effect of the addition of low-dose human chorionic gonadotropin (hCG) to ovarian stimulation with recombinant follicle stimulating hormone (rFSH) on in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcome. Materials and Methods: This retrospective clinical study was conducted on 141 women undergoing ICSI through a short GnRH-agonist protocol with rFSH and the addition of low-dose (100 IU/day) hCG. The control group consisted of 124 women undergoing ovarian stimulation with a similar protocol devoid of hCG. Statistical analysis in the study population along with a subgroup analysis for age ≥ 35 years and ≥ 36 years was performed. Results: Women in hCG group were statistically significant older and with higher basal FSH compared to control group. This can be attributed to the Centre’s latent tendency to add hCG in the stimulation protocol in poor prognosis patients. Despite this fact and the fact that several ovarian stimulation parameters, such as peak estradiol levels, number of oocytes retrieved, number of mature oocytes, and fertilization rates were in favor of the control group, the quality of transferred embryos and pregnancy rates were in favor of hCG group. Similar results were obtained in the subgroup analyses apart from peak estradiol levels, which did not differ among the study groups. Conclusions: The addition of hCG to rFSH may be associated with better quality embryos and higher pregnancy rates, even in women of advanced reproductive age with higher basal FSH levels, which are often considered to have poorer ovarian reserve.
