Columbia Laboratories, Inc. Release: Ongoing Pregnancy Rates Among Infertility Patients With Luteal Phase Bleeding No Different With Vaginal Gel or Injectable Progesterone, Brigham and Women's Hospital Study

LIVINGSTON, N.J. & SAN FRANCISCO--(BUSINESS WIRE)--Researchers from Brigham & Women’s Hospital in Boston today presented data demonstrating that women undergoing In Vitro Fertilization (IVF) and using either vaginally-administered progesterone gel (CRINONE® 8%) or progesterone injected intramuscularly for luteal phase supplementation, reported no difference in ongoing pregnancy rates when they experienced luteal phase bleeding (LPB). LPB is defined as any bleeding or spotting between embryo transfer and first pregnancy test. LPB occurred with both CRINONE and intramuscular (IM) progesterone injections. These data were presented by Elena H. Yanushpolsky, MD, at the American Society for Reproductive Medicine annual meeting in San Francisco.
