Introducing the Evolutionary Phenomenon of Gısır: Stress-Induced Infertility as an Adaptive Reproductive Suppression Mechanism

Introducing Gısır: A New Evolutionary Framework for Understanding Stress-Induced Infertility What if infertility is not always a disease, but sometimes an adaptive response—a biological signal that the body does not feel safe enough to reproduce? This paper introduces Gısır (pronounced /ɡɯˈsɯɾ/), a new conceptual term for the evolutionary phenomenon in which perceived environmental insecurity and psychological stress suppress reproductive processes. Drawing on a real-world observational case—a female bird that ceased egg-laying in an unsafe environment and resumed normal reproduction once safety was restored—the paper argues that stress-induced infertility is not a malfunction to be cured, but an ancient survival strategy shaped by natural selection. The authors propose that this mechanism may exist not only in birds but also in mammals, including humans. If confirmed, this idea could transform the way we understand and treat infertility—shifting the focus from pharmaceutical and surgical interventions alone toward environment-based, psychologically informed approaches that restore a patient's sense of safety. Rather than claiming definitive proof, this paper offers a testable hypothesis and invites the scientific community to validate, challenge, and extend the Gısır framework. It is a call to rethink infertility—not as a failure of the body, but as a message from it.
