Follicle-stimulating hormone (FSH) is a gonadotropin, a glycoprotein polypeptide hormone. [1] FSH is synthesized and secreted by the gonadotropic cells of the anterior pituitary gland [ 2 ] and regulates the development, growth, pubertal maturation , and reproductive processes of the body.
By contrast, the hormones of the anterior pituitary gland (the adenohypophysis) are secreted from endocrine cells that, in mammals, are not directly innervated, yet the secretion of these hormones (adrenocorticotrophic hormone, luteinizing hormone, follicle-stimulating hormone, thyroid-stimulating hormone, prolactin, and growth hormone) remains ...
Proper hormone secretion is crucial for the growth of the developing fetus.In order to allow a controlled hormone secretion in the developing organs of the fetus, stimulating hormones must be exchanged in the regulating structures in the brain in early stages of the development.
The anterior portion of the pituitary gland produces luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and the gonads produce estrogen and testosterone. In oviparous organisms (e.g. fish, reptiles, amphibians, birds), the HPG axis is commonly referred to as the hypothalamus-pituitary-gonadal-liver axis (HPGL-axis) in females ...
These brain cells control reproduction by secreting GnRH into the hypophyseal portal capillary bloodstream, so are sometimes referred to as "sex neurons". This small capillary network carries GnRH to the anterior pituitary, causing release of luteinizing hormone (LH) and follicle stimulating hormone (FSH) into the wider bloodstream. When GnRH ...
Gonadotropic cells (also known as gonadotropes, gonadotrophs, delta cells, or delta basophils) are endocrine cells in the anterior pituitary that produce gonadotropins.More specifically, gonadotrophs produce and secrete glycoprotein polypeptide hormones, such as the follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are released due to the positive input of gonadotropin ...
The blood vessels carry the peptides to the anterior pituitary gland, where they regulate the secretion of hormones into the systemic circulation. The parvocellular neurosecretory cells include those that make: Corticotropin-releasing hormone (CRH), which regulates ACTH secretion from the anterior pituitary gland
The ability of Sertoli cells to change the immune response in the tubule is needed for successful sperm cell maturation. Sperm cells express neo-epitopes on their surface as they progress through different stages of maturation, which can trigger a strong immune response if placed in a different part of the body.
