What this trial studies

This study evaluates the effectiveness of the progestin-primed ovarian stimulation (PPOS) protocol against the standard GnRH antagonist protocol in women undergoing in-vitro fertilization (IVF). Conducted as an open-label, randomized controlled trial, it aims to determine the difference in the number of retrieved oocytes between the two protocols. The study will involve 200 participants, with 100 women receiving each treatment, and will take place at the Assisted Reproduction Center of Tam Anh General Hospital and Hanoi Medical University. The trial is designed to provide insights into optimizing IVF protocols for better outcomes.

Who should consider this trial

Good fit: Ideal candidates are women aged 20 to 45 experiencing infertility due to male factors, fallopian tube issues, or unknown causes.

Not a fit: Patients with contraindications to ovarian stimulation, systemic diseases, or those who have taken hormone drugs recently may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved IVF success rates for women undergoing treatment.

How similar studies have performed: Previous studies have shown varying success with different ovarian stimulation protocols, making this approach both relevant and necessary for further exploration.
