Question

question 1 (1 point) listen the initiation of female puberty is primarily driven by: a decrease in hypothalamic sensitivity to negative feedback from gonadal steroids. an increase in adrenal androgen production (adrenarche). the pulsatile release of gnrh from the hypothalamus. the direct stimulation of the ovaries by the pituitary gland.

Explanation:

The initiation of female puberty is mainly triggered by the pulsatile release of gonadotropin - releasing hormone (GnRH) from the hypothalamus. This stimulates the pituitary - gonadal axis. A decrease in hypothalamic sensitivity to negative feedback from gonadal steroids is part of the long - term regulation but not the primary initiator. Adrenarche, the increase in adrenal androgen production, is related to pubarche (appearance of pubic hair) but not the primary trigger of puberty. The direct stimulation of the ovaries by the pituitary gland occurs after the hypothalamus initiates the process by releasing GnRH.

Answer:

C. The pulsatile release of GnRH from the hypothalamus.
