A new study published in Nature Aging shows that fecal microbiota transplants from older female mice improved ovarian function and fertility in younger mice. (USC Leonard Davis School of Gerontology)
The research was led by Dr. Bérénice Benayoun (senior author) at the USC Leonard Davis School of Gerontology, with Dr. Min Hoo Kim as first author.
Key findings from the study:
- Young mice receiving microbiota from older “estropausal” mice showed improved ovarian health markers, including hormone levels and follicle counts.
- Reproductive outcomes improved: all mice receiving the older microbiome produced offspring.
- Molecular analysis suggested reduced inflammation and ovarian gene expression patterns resembling younger tissue profiles. (USC Leonard Davis School of Gerontology)
The findings highlight a potential two-way communication between the gut microbiome and the ovaries, raising the possibility that microbiome modulation could eventually influence fertility or reproductive aging.
Important caveat: these results are currently limited to mouse models.
During ISM 2026 we will discuss about this hot topic.

The surprising findings shed light on the little-known relationship between the microbiome and the reproductive system. Greater understanding could lead to better treatment options not only for fertility but also for overall health as women age.
