claimGonadotropin-releasing hormone (GnRH), produced by the hypothalamus, regulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary gland.
claimThe onset of male puberty is stimulated by a rise in gonadotropin-releasing hormone (GnRH) from the hypothalamus, which triggers the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary.
claimThe hypothalamus secretes the peptide hormone GnRH (gonadotropin-releasing hormone) in a pulsatile fashion into the hypothalamo-hypophyseal portal system to stimulate the anterior pituitary.
claimGnRH stimulates the anterior pituitary by binding to and activating a G protein receptor on gonadotrophs, which triggers inositol 1,4,5-triphosphate (IP3) activation and increases intracellular calcium, leading to the release of FSH (follicle-stimulating hormone) and LH (luteinizing hormone).
claimThe hypothalamus releases corticotrophin-releasing hormone (CRH), which stimulates the anterior pituitary to release adrenocorticotropic hormone (ACTH).
claimThe anterior pituitary secretes LH and FSH into the blood, which act on membrane receptors in the Leydig and Sertoli cells of the testes, respectively.
claimThe hypothalamic-pituitary-adrenal axis is controlled by the hypothalamus and anterior pituitary, functioning similarly to the hypothalamic-pituitary-gonadal axis.
claimEstradiol and estrogen play roles in bone resorption, epiphyseal closure, gynecomastia, and vascular effects, and they exert an inhibitory effect on the hypothalamus and anterior pituitary.
claimTestosterone acts on the hypothalamus and anterior pituitary via negative feedback to decrease the secretion of LH and FSH.

claimThe anterior pituitary produces hormones that stimulate the thyroid, adrenal cortex, ovaries, testicles, and mammary glands to increase their own hormone production.
claimThe anterior pituitary produces growth hormone, a protein that influences metabolic activity by causing the body to store carbohydrates, synthesize proteins for growth, and use fat for energy.

claimGonadotropins are secreted in a pulsatile fashion from the anterior pituitary, with pulse frequency and amplitude varying according to the phase of the menstrual cycle.

claimFollicle-stimulating hormone (FSH) and luteinizing hormone (LH) are released from the anterior pituitary gland and modulate the production of hormones in the testes.
Physiology, Menstrual Cycle - StatPearls - NCBI Bookshelf ncbi.nlm.nih.gov Sep 27, 2024 1 fact
claimGonadotropin-releasing hormone (GnRH) travels to the anterior pituitary gland, where it activates G protein–coupled receptors, signaling the pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
