Solution
The correct option is B GnRH
- GnRH is a peptide hormone synthesized and released from GnRH neurons within the hypothalamus. It stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary.
- Follicle-stimulating hormone (FSH) stimulates the ovarian production of estrogens by the granulosa cells of the ovarian follicles and corpora lutea.
- Estrogens produce wide-ranging actions such as stimulation of growth and activities of female secondary sex organs, development of growing ovarian follicles, the appearance of female secondary sex characters (e.g., high the pitch of voice, etc.), mammary gland development. Estrogens also regulate female sexual behaviour.
- Hence GnRH hormone initiates the development of secondary sexual characters in the female.
- So, the correct answer is 'GnRH'.
