Summary

This trial is a dose-response study of Endometrin, a progesterone supplement, during in vitro fertilization (IVF). The usual dose of Endometrin is 100 mg two to three times per day. The purpose of this research project is to evaluate the dose response of the Endometrin when determined based on the blood level of progesterone on the day of the FET. The hypothesis is that a woman with low progesterone levels would benefit from a higher dose of Endometrin. PIBF (Progesterone Induced Blocking Factor) levels, a protein found in the blood that could also predict

Who is the study for?
This trial is for women aged 18-42 undergoing their first or second frozen embryo transfer (FET) with a normal uterine cavity and adequate endometrial thickness. It's not for those with uterine abnormalities, cancer, certain drug use, gastrointestinal issues, thromboembolism history, severe organ disease, allergies to NSAIDs or progesterone components.
What is being tested?
The study tests if adjusting the dose of Endometrin based on blood progesterone levels improves pregnancy chances in IVF. Women with low progesterone may receive a higher dose (600 mg), while others continue the standard (300 mg). The research also examines PIBF levels as potential predictors of IVF success.
What are the potential side effects?
Possible side effects from Endometrin include local irritation or inflammation at the site of insertion, headaches, breast tenderness, mood swings and cramping. Some individuals might experience allergic reactions if sensitive to the medication's ingredients.
