What this trial studies

This clinical trial aims to compare clinical pregnancy rates between two groups of women undergoing frozen embryo transfer who have progesterone levels below 10 ng/mL on transfer day. One group will receive vaginal micronized progesterone supplemented with intramuscular progesterone, while the other group will receive vaginal micronized progesterone without additional supplementation. The study is a single-center, randomized, controlled trial that will monitor various diagnostic and clinical outcomes throughout the process. Participants will be women aged 18-45 with normal BMI undergoing assisted reproductive technology.

Who should consider this trial

Good fit: Ideal candidates are women aged 18-45 with low progesterone levels undergoing frozen embryo transfer.

Not a fit: Patients with conditions such as uterine abnormalities, history of recurrent implantation failure, or those undergoing oocyte donation or surrogacy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve clinical pregnancy rates for women with low progesterone levels during embryo transfer.

How similar studies have performed: Previous studies have shown varying success with progesterone supplementation in similar contexts, but this specific approach is being evaluated in a controlled setting.
