Información del artículo

Stress, as a general mechanism of sympathetic response, produces marked changes in the homeostasis of the body. It is well known that stress produces profound changes in sexual behavior and reproductive performance. In the present study we discuss stress-induced sympathetic nerve-mediated ovarian disturbance, which causes the most frequent ovarian disorder in women of reproductive age: polycystic ovary syndrome. We review central and peripheral mechanisms of regulation of sympathetic nerve activity and their role in polycystic ovary syndrome and provide a succinct outline of our findings in this area. The use of animal models to study the role of stress as an etiological factor in ovarian disorders and to translate this knowledge to patients with polycystic ovary syndrome provides strong support for the involvement of sympathetic nerves in normal and abnormal ovarian function.

Key words:
Stress
Polycystic ovary
Sympathetic innervation
Hyperandrogenemia
Palabras clave:
Estrés
Ovario poliquístico
Inervación simpática
Hiperandrogenemia

El estrés, como un mecanismo general de respuesta simpática exagerada, involucra grandes cambios en la homeostasis del organismo. No existen dudas acerca de las alteraciones que provoca el estrés, tanto en el comportamiento sexual como en la capacidad reproductiva. En este trabajo discutiremos los cambios en la actividad nerviosa simpática que induce el estrés y su participación en la enfermedad ovárica de mayor frecuencia en mujeres durante su vida reproductiva, el síndrome del ovario poliquístico. Presentamos una revisión de los mecanismos centrales y periféricos de regulación de la actividad nerviosa simpática y su participación en el síndrome del ovario poliquístico. Se discuten los resultados de nuestro grupo en esta área. El uso de modelos animales para estudiar la participación del estrés en la enfermedad ovárica y trasladar este conocimiento hacia pacientes con síndrome del ovario poliquístico apoya fuertemente la participación de los nervios simpáticos en la función ovárica en condiciones normales y patológicas.
