Luteal Support in Artificial Vitrified/Warmed Cycles With Low Progesterone (PROTECTA)
February 2, 2024 updated by: University Hospital, Ghent
Randomized Controlled Trial Comparing Micronized Progesterone (Amelgen ®) 400 mg BID Versus 400 mg TID for Luteal Support in Artificial Vitrified/Warmed Single Blastocyst Transfer Cycles With Low Progesterone on Day of Embryo Transfer
The study aims to evaluate the effect of an increased dose of vaginal progesterone supplementation on the incidence of ongoing pregnancy for patients with a suboptimal serum progesterone level (defined as < 10 mcg/l) on the day of blastocyst transfer.
