Explain why steroids are responsible fr the secondary sex characteristics
Step by step
Solved in 3 steps
- The sex response is an inborn reflex. What stimuli trigger the reflex? What two physiological mechanisms (other than the brain) are responsible for the physical changes that appear during the sexual response? [Hint: One begins with “va” and the other with “my.”] Give examples of the effects of both these two physiological mechanisms.Explain briefly what is lethal sexExplain sex determination in humans?
- Describe the phases of the human sexual response.The sex steroids include: estrogen, progesterone, testosterone, FSH and LH estrogen, progesterone, testosterone, FSH, LH, and GnRH O estrogen, progesterone, and testosterone O FSH and LHList three different menopausal symptoms that can be counteracted by HRT (hormone replacement therapy). What is the reason why both estrogen and progestin are often included in these preparations?
