Administration of inhibin would not result in an FSH surge such as that described in the scenario above.Ĭhoice D: Prolonged administration of progesterone inhibits GnRH-induced FSH secretion from the anterior pituitary.Ĭhoice E: Testosterone normally provides the negative feedback for LH and does not directly affect FSH, although very high nonphysiologic levels of testosterone will reduce plasma FSH due to suppression of GnRH release. Family issues are also gradually revealed as the series progresses. Inhibins are produced in response to FSH and once released, inhibit FSH secretion. Watch Hormones Season 2 Episode 1 English Subbed on Myasiantv, Features experiences and. A pulsatile infusion that mimics the normal pattern of GnRH release from the hypothalamus would promote a sustained increase in LH through GnRH receptor upregulation and gonadotroph sensitization.Ĭhoice C: Inhibins are peptide hormones produced by follicular granulosa cells that create a negative feedback control pathway regulating FSH secretion by the anterior pituitary. GnRH administration would initially stimulate FSH and LH secretion, but levels of both hormones would then fall due to downregulation of the GnRH receptors. Why the other answers are wrong Why the other answers are wrongĬhoice B: Gonadotropin-releasing hormone (GnRH) is produced by the hypothalamus and targets gonadotropes in the anterior pituitary.
