Question

question 2 (1 point) listen adrenarche, the increased production of adrenal androgens, is a crucial developmental stage preceding gonadarche in females. what is its primary role in sexual maturation? it directly stimulates thelarche (breast development). it initiates the pulsatile secretion of gonadotropin - releasing hormone (gnrh). it contributes to the development of pubic and axillary hair. it causes uterine growth that leads to menarche.

Explanation:

Adrenarche involves increased adrenal androgen production. These androgens are responsible for the development of pubic and axillary hair in females during sexual maturation. Breast development (thelarche) is mainly due to estrogens. The pulsatile secretion of GnRH is part of the hypothalamic - pituitary - gonadal axis activation which is not directly initiated by adrenarche. Uterine growth leading to menarche is also mainly regulated by estrogens and other factors in the reproductive hormonal cascade.

Answer:

It contributes to the development of pubic and axillary hair.
