Updated PPOS evidence: benefit and study quality

What was investigated and what was found?

A meta-analysis of 20 trials reported higher live-birth probability with PPOS than antagonists. Bias and trustworthiness concerns require interpreting the result within the relevant protocols and patient groups.

Interpreting the findings

Patient groups, methods and bias risks can differ across studies. A pooled estimate is not a personal treatment recommendation or a guarantee of benefit.

How can you prepare for a consultation?

Planning involves previous response, medication burden and hyperstimulation risk as well as egg yield. Review your previous protocol with Prof. Dr. Mehmet Çolakoğlu to clarify questions about a future cycle.
