We compared the efficiency of progesterone vaginal gel (PVG) with intramuscular progesterone (IMP) supplementation for luteal phase support after in vitro fertilization and embryo transfer in gonadotropin-releasing hormone (GnRH) antagonist cycles. The treatment outcomes were similar for PVG and IMP for luteal support in GnRH-antagonist protocols. With its ease of use, high tolerability by patients, and fewer side effects, PVG can be a successful alternative to IMP.
