Could a blood injection revive aging ovaries?
NCT ID NCT03951194
First seen Jul 08, 2026 · Last updated Jul 09, 2026 · Updated 1 time
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.
