What this trial studies

This clinical trial investigates the use of GnRH agonists to provide additional support for the endometrium during in vitro fertilization (IVF) cycles. The study aims to determine whether a single administration of GnRH around the time of embryo transfer can enhance implantation and live birth rates compared to a placebo. Women under 40 undergoing IVF or frozen embryo transfers will be eligible to participate. The trial will assess the effectiveness of this intervention in improving reproductive outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are women under 40 years old who are undergoing IVF, ICSI, or frozen embryo transfers.

Not a fit: Patients who are undergoing day 3 embryo transfers may not receive benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve implantation rates and live birth outcomes for women undergoing IVF.

How similar studies have performed: Other studies have shown promising results with similar approaches, indicating potential for success in this trial.
