Summary

This study investigates whether injecting a woman's own platelet-rich plasma (PRP) into her ovaries can restart regular menstrual cycles and improve hormone levels. The trial includes perimenopausal women aged 40 and older who have irregular cycles or elevated FSH. Participants receive either PRP or a placebo injection, and researchers track menstrual regularity and hormone changes over three months.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Platelet Rich Plasma (PRP)
What this could lead to
If it works, this could offer a way to restore menstrual cycles and improve fertility in perimenopausal women without hormone therapy.
What could go wrong
This is an early-phase trial with a small number of participants. The effects may be temporary, and not all women may respond. Risks include infection or discomfort from the injection procedure.
