Estrogen production from the Graafian Follicle gradually reduces FSH release from the Anterior Pituitary via negative feedback.
Follicle-stimulating hormone (FSH) secretion is primarily regulated by gonadotropin-releasing hormone (GnRH) from the hypothalamus. GnRH stimulates the release of FSH from the anterior pituitary gland. Additionally, negative feedback from sex steroids such as estrogen and testosterone can also influence FSH secretion.
The pituitary gland receives feedback signals from the target organs it influences through hormones. These signals help regulate the pituitary's secretion of hormones to maintain balance in the body. Thus, the pituitary takes orders indirectly by responding to the needs of the target organs.
High levels of testosterone will inhibit the A hypothalamus and B anterior pituitary gland through a negative feedback loop. Testosterone signals to the hypothalamus and anterior pituitary gland to reduce the production of gonadotropin-releasing hormone (GnRH) and luteinizing hormone (LH), which in turn decreases testosterone production.
The hypothalamus regulates the Pituitary gland, and the Pituitary gland regulates the rest of the endocrine system.
hypothalamus of the brain secretes neural hormone which controls the pituitary gland, secretions of pituitary gland are popularly called as trophic hormones which control all other endocrine glands of human body
LH triggers the interstitial cells of the testes to produce testosterone. Testosterone levels are are measured by the pituitary gland and if the levels are high enough, the pituitary gland shuts off the secretion of LH. Its a process called negative feedback.
The pituitary gland (anterior) is responsible for secretion of GH. Regulation is via the negative feedback system's Hypothalamus, running through the hypothalamic nerve, at the top of the gland.

Gonadotropin-releasing hormone (GnRH) is a neurohormone secreted by the preoptic nuclei of the hypothalamus. This hormone causes leuteinizing hormone to be released by the anterior pituitary. LH works its way through the bloodstream to the ovaries, which produce estrogen. Estrogen has a feedback loop with both the hypothalamus and the anterior pituitary. Whether the mechanism is positive or negative depends. In ovulation, this mechanism is positive, so high estrogen levels will induce even higher LH levels.
