Question

question 5 (1 point) the gradual increase in estrogen and testosterone levels during puberty eventually leads to: decreased gnrh pulse frequency. increased sensitivity of the pituitary to gnrh. negative feedback on the hypothalamus, but positive feedback on the pituitary. positive feedback on the hypothalamus, but negative feedback on the pituitary.

Explanation:

During puberty, the rise in estrogen and testosterone levels exerts negative - feedback on the hypothalamus, reducing the secretion of Gonadotropin - releasing hormone (GnRH). This leads to decreased GnRH pulse frequency. There is no positive feedback on the pituitary in this context. The pituitary's sensitivity to GnRH does not increase in the described manner due to the increase in sex - hormone levels.

Answer:

Decreased GnRH pulse frequency.
