Building on previous findings, Brigham and Women’s Hospital researchers report that the immunity imbalance predisposing to herpes simplex virus-2 (HSV-2) isn’t limited to the cervix but rather extends to the systemic circulation. HSV-2 may alter both mucosal and peripheral innate immunity to contribute to HIV-1 risk.

Minimally invasive surgery is often promoted as a way to reduce postoperative pain after benign gynecological surgery. However, Brigham researchers found vaginal and laparoscopic hysterectomy for treatment of pelvic organ prolapse appear to be similar with regard to postoperative pain medication requirements.

Elevated Estradiol on Day of Progesterone Initiation Is Detrimental After Frozen Embryo Transfer

Close up of green tray with researcher removing embryo frozen in liquid nitrogen for IVF procedure

Many IVF programs freeze embryos to mitigate risk of elevated estradiol levels that can negatively affect conception and live birth. However, Brigham researchers determined elevated estradiol levels at the time of progesterone initiation have similarly negative effects on outcomes after frozen embryo transfer cycles.
