NCT ID NCT04670393
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a special supplement containing antioxidants and probiotics could improve egg quality in women with polycystic ovary syndrome (PCOS) undergoing IVF. Twenty women took either the supplement or a placebo (just folic acid) during their IVF cycle. Researchers measured the number of mature eggs and markers of oxidative stress and gut health.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- antioxidant food supplement with probiotics (FertyBiotic Woman Plus)
- What this could lead to
- If it works, this could point toward a way to improve egg quality and IVF success for women with PCOS.
- What could go wrong
- This is a very small, early study with only 20 participants. The supplement may not show a clear benefit, and results may not apply to all women with PCOS.
