Somatostatin, for instance, inhibits the release of growth hormone, while dopamine acts as a prolactin-inhibiting factor. Similarly, gonadotropin-releasing hormone (GnRH) controls the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH).

Anatomy and Structure of the Hypophyseal Portal System The system is anatomically divided into two capillary beds connected in series by hypophyseal portal veins. The hypophyseal portal veins form a critical component of the endocrine system, serving as the vascular bridge between the hypothalamus and the anterior pituitary.
Physiological Function and Hormonal Regulation The primary function of the hypophyseal portal veins is to convey hypothalamic tropic hormones to the anterior pituitary without significant dilution in the systemic circulation. This ensures a high concentration of regulatory hormones at the target cells.

The first capillary plexus, known as the primary or hypothalamic plexus, is located in the median eminence, a protrusion of the hypothalamus into the pituitary stalk. From this plexus, blood drains into the hypophyseal portal veins, which travel through the pituitary stalk.
