Effects of E2 (Estradiol), P4 (Progesterone) and LH Levels on the Day of Transfer and Endometrial Cavity Thickness on Implantation Success in Patients With Frozen-thawed Embryo Transfer Cycle: Prospective Data Analysis
In Brief
A clinical study evaluating Normal Progesterone group and Low Progesterone group for Infertility and 2 related conditions. Completed, enrolled 238 participants across 2 sites.
Detailed Summary
Thanks to recent advances in clinical practice and laboratory, embryo cryopreservation has become the first-line procedure in assisted reproductive technology. Embryo freezing process; Prevention of ovarian hyperstimulation syndrome is becoming an accepted practice for a growing number of indications, including preimplantation genetic testing (PGT), late follicular phase progesterone elevation, and embryo-endometrial asynchrony. Progesterone; plays a key role in the preparation of the endometrial cavity for embryo attachment. Supplementary progesterone preparations can be used to prevent luteal phase defects and provide progesterone support during cycle preparations for frozen-thawed embryo transfer. Our aim in this study is to show the effect of serum progesterone level on pregnancy outcomes on the day of embryo transfer.
Study Details
Timeline
Interventions
Progesteron supplementation was initiated by the use of 100 mg of a vaginal progesterone tablet two times daily (Lutinus, Ferring Pharmaceuticals) plus 250 mg of intramuscular hydroxyprogesterone caproate in oil twice a week (IMHPC) as luteal phase support (referred to as day 0 of progesterone administration).
Progesterone level \<10 ng/mL on ET day. If serum progesterone levels were \<10 ng/ml at ET day, 25 mg/d of SC progesterone daily (Prolutex) was given to patients and ET was performed on the same day and the blood sample was taken 2 days later to check serum progesterone levels.
