Abstract

PURPOSE:

This analysis was performed to evaluate the effects of intrauterine injection of human chorionic gonadotropin (hCG) before fresh embryo transfer (ET) on the outcomes of in vitro fertilization and intracytoplasmic sperm injection.

METHODS:

Randomized controlled trials (RCTs) were identified by searching electronic databases. The outcomes of live birth, clinical pregnancy, implantation, biochemical pregnancy, ongoing pregnancy, ectopic pregnancy, and miscarriage between groups with and without hCG injections were analyzed. Summary measures were reported as risk ratios (RR) with 95% confidence intervals.

RESULTS:

Six RCTs on fresh embryo transfer (ET) were included in the meta-analysis. A total of 2759 women undergoing fresh ET were enrolled (hCG group n = 1429; control group n = 1330). Intrauterine injection of hCG significantly increased rates of biochemical pregnancy (RR 1.61) and ongoing pregnancy (RR 1.58) compared to controls. However, there were no significant differences in clinical pregnancy (RR 1.11), implantation (RR 1.17), miscarriage (RR 0.91), ectopic (RR 1.65) or live birth rates (RR 1.13) between the hCG group and control group.

CONCLUSION:

The current evidence for intrauterine injection of hCG before fresh ET does not support its use in an assisted reproduction cycle.
