Prospective randomized study.
The Egyptian IVF-ET Center.
Infertility patients younger than 40 years undergoing their first in?vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI).
The study group (n = 167) received either 100 IU of hCG (n = 83), or 200 IU of hCG (n = 84) via intrauterine administration before ET. The control group (n = 93) underwent ET without hCG. After the interim analysis, the modified study group (n = 107) received intrauterine injection of 500 IU of hCG, and the control group (n = 105) underwent ET without hCG.
Clinical pregnancy rate (PR) and implantation rate (IR).
The IR and PR were statistically significantly higher in the 500 hCG group (41.6 % and 75 % , respectively) as compared with the control group (29.5 % and 60 % , respectively). The IR and PR were 26.6 % and 54 % in the 100 hCG group, 28.3 % and 57 % in the 200 IU hCG group, and 29.4 % and 60 % in the control group, respectively, with no statistically significant difference.
Intrauterine injection of 500 IU of hCG before ET statistically significantly improved the implantation and pregnancy rates in IVF/ICSI.
