Briefings

A major international study published in 2026 challenges the long-held view that cortisol is a reproductive enemy. The research suggests cortisol may actually promote healthy reproduction rather than hindering it, potentially acting as a beneficial signal for fertility. This finding represents a significant shift in understanding the complex hormonal interactions within the reproductive system, offering new insights into how stress hormones influence reproductive success.
