Add MORE Progestin for Progestin BTB? (New Data)
Manage episode 503631843 series 2280622
Traditionally, we have learned that any imbalance in the estrogen: progesterone relationship can trigger irregular uterine bleeding. That makes sense, right? During anovulation, prolonged unopposed estrogen can result in HMB. In such a case, we give progesterone as both a therapeutic as well as diagnostic intervention. On the contrary, with progestin only contraception, we consider estrogen predominant products when progesterone breakthrough bleeding (BTB) occurs to restore endometrial stabilization. But a new RCT (AJOG) adds credence to adding MORE progesterone in cases of progesterone associated BTB. Listen in for details.
