प्रश्न
Briefly mention the mechanism of action of FSH.
उत्तर
- Follicle-stimulating hormone (FSH) is secreted by the pars distalis region of the anterior pituitary. It regulates the development, growth, and reproductive processes of the human body. In the ovary, FSH stimulates the growth and maturation of ovarian follicles.
- As the follicle grows and matures, it releases an inhibitory hormone known as inhibin that ends the process of FSH production.
- Follicle-stimulating hormone produces its effect by binding to its specific receptors present on the ovarian cell membrane.
- The binding of FSH hormone to its receptor leads to the formation of a hormone receptor complex. The formation of this complex leads to biochemical changes in the ovarian follicle. The ovarian follicles mature and release a mature ovum in the fallopian tube for fertilization.

You have learnt that a characteristic feature of endocrine system is the presence of feed back loops. By this what is meant if hormone A stimulates gland ‘X’ to secrete hormone B, the production of ‘A’ could be modified when the level of B changes in our blood. An example is the relation between hormones LH and estrogen (E2). An old woman exhibits the following features. High levels of LH in blood but low levels of E2 in the blood. Another woman exhibits high level of LH in blood and also high level of E2 in the blood. Where is the defect in both these women? Provide suitable diagram to support this answer.
