Anteroventral Periventricular Nucleus

Meaning

The Anteroventral Periventricular Nucleus (AVPV) is a specialized, sexually dimorphic cluster of neurons situated in the anterior region of the hypothalamus near the third ventricle. This nucleus serves as a pivotal central nervous system integrator for the endocrine system, primarily controlling the pulsatile release of key reproductive hormones. Its structure and function exhibit significant differences between sexes, making it central to the distinct hormonal cycles of males and females. The AVPV’s role in governing reproductive neuroendocrine function is indispensable for fertility and hormonal homeostasis.
