From Gynecological Endocrine Disorders to Cardiovascular Risk: Insights from Rat Models

Gynecological endocrine disorders, including polycystic ovary syndrome (PCOS), endometriosis as well as primary ovarian insufficiency (POI)/premature ovarian failure (POF), significantly impact women's reproductive health and overall well-being. While these conditions are primarily driven by disturbances of the hypothalamic-pituitary-gonadal axis, yet growing evidence indicates that oxidative stress plays a crucial role in their development and progression. The combined impact of hormonal imbalance and impaired redox homeostasis contributes to infertility, metabolic dysfunction, and other co-morbidities, such as increased cardiovascular risk. Given that women may live for many years with these chronic conditions, investigating their pathophysiology and associated complications is of particular importance. This narrative review summarizes current knowledge on PCOS, endometriosis, and POI/PMF, emphasizing the contribution of oxidative stress and also highlights the association between these disorders and cardiovascular risk. Furthermore, the utility of rat models is presented to support the advancement of preventive and therapeutic research.
