Which ones stimulate production of oestrogen at puberty?

Question

Accepted Answer

The correct option is 1:

At puberty, the body undergoes significant hormonal changes that lead to sexual maturation. In females, the primary sex hormones involved are estrogen and progesterone. The production of estrogen is stimulated by gonadotropins, which are hormones secreted by the anterior pituitary gland. These gonadotropins are Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH). FSH plays a crucial role in stimulating the growth and development of ovarian follicles, which are structures in the ovaries that contain immature eggs. As these follicles mature, they produce and secrete increasing amounts of estrogen. LH, on the other hand, triggers ovulation and also stimulates the remaining follicular cells to transform into the corpus luteum, which then produces both estrogen and progesterone. Thus, the coordinated action of FSH and LH is essential for initiating and maintaining estrogen production during puberty and throughout the reproductive years.

The incorrect option is 2: ACTH (Adrenocorticotropic Hormone) is produced by the pituitary gland but primarily stimulates the adrenal glands to produce cortisol and other adrenal hormones. It is not directly involved in the stimulation of estrogen production by the ovaries.

The incorrect option is 3: TSH (Thyroid-Stimulating Hormone) is also produced by the pituitary gland but its main function is to stimulate the thyroid gland to produce thyroid hormones, which regulate metabolism. TSH does not have a direct role in stimulating estrogen production.

The incorrect option is 4: GH (Growth Hormone) is produced by the pituitary gland and is responsible for promoting general body growth and development. While it plays a role in overall development during puberty, it does not directly stimulate the production of estrogen.
