NEET BIOLOGY

Detailed explanation-1: -FSH stimulates the production and maturation of sex cells, sperm in males, and ova in females. It also promotes follicular maturation in females during the ovarian cycle; these follicles then release estrogen in the female ovaries.

Detailed explanation-2: -GnRH stimulates the pituitary gland to produce follicle stimulating hormone (FSH), the hormone responsible for starting follicle (egg) development and causing the level of estrogen, the primary female hormone, to rise.

Detailed explanation-3: -The hypothalamus produces GnRH, and it is released into the hypophyseal portal circulation to act on G-protein-coupled receptors at gonadotropic cells of the anterior pituitary. Those gonadotropic cells produce FSH and luteinizing hormone (LH) and release them into the peripheral circulation.

Detailed explanation-4: -Prolactin: Prolactin stimulates breast milk production (lactation) after giving birth. It can affect fertility and sexual functions in adults. Thyroid-stimulating hormone (TSH): TSH stimulates your thyroid to produce thyroid hormones that manage your metabolism, energy levels and your nervous system.

Detailed explanation-5: -FSH secretion is suppressed by negative feedback of the ovarian hormones estradiol, inhibin, and progesterone during the early and midluteal phase.
