Conditions

Premature Luteinization

Brief summary

Previous studies have suggested that premature luteinization (PL)during controlled ovarian stimulation (COS) decreases the implantation rate due to a negative effect on the endometrium receptivity. This study aims to describe the impact on endometrial gene expression of PL in GnRH antagonist and GnRH agonist cycles.
