Hormone replacement therapy was advertised first to women in the 1990s as a way of increasing their youthfulness. Hormone replacement therapy today is usually taking pills to increase someone's estrogen or testosterone supply. Pick either estrogen or testosterone.
For either one:
1) How does your chosen sex hormone work at the cellular and at the molecular level?
2) How do these hormones improve the reproductive system as a whole?
3) What are the benefits of doing hormone replacement therapy?
4) What are the harms of doing hormone replacement therapy?
5) Who would be an ideal candidate for hormone replacement therapy?
The figure shows that many male powerlifters had testosterone levels below the 10 nmol/L threshold, (lower than average testosterone levels of male athletes in other sports). Do lower testosterone levels result from some aspect of powerlifting training or do men with lower testosterone levels have an advantage in powerlifting? What does this have to do with effects of testosterone, skeletal muscle, lung capacity, energy storage and consumption?
Select the two different ways that chemicals that might cause problems with sexual development and reproduction work
- Estrogen mimics disrupt the endocrine system by attaching to molecules that except the hormone estrogen
- estrogen prevents testosterone from developing.
- hormone blockers keep certain hormones from attaching to their receptors.
- hormone blockers help certain hormones attach to their receptors.

More recently, experiments with hormone replacement therapy revealed that women on HRT have an increased risk of breast cancer. What studies should we believing they are telling us the truth about the efficacy and / or risk of replacement therapy hormonal? Please provide an explanation of why there was a difference.arrow_forward
- Give the rationale behind the hormonal ingredients used in the formulation of the female contraceptive pill. What are the side-effects of the use of such pills, and how does modern pharmacology address these issues?arrow_forwardResearchers designed an observational study to investigate the effects of hormone replacement therapy investigating whether hormone replacements caused heart disease or cancer. In this experiment, which would NOT be a possible confounding variable? a) History of breast cancer in the family b) The use of birth control pills c) The wealth of women (wealthier more able to afford health insurance) d) Whether women were put into a group taking the medication vs. a group taking a placeboarrow_forwardThere is considerable advertising directed at men in their 50s and older suggesting that they can reverse the effects of aging by taking supplemental testosterone ( "maybe you have low T!") . Surprisingly, their doctors often comply with requests for supplemental testosterone with little or no testing to find out if their levels are actually abnormal. It turns out abnormally low testosterone levels are fairly rare in men, so not surprisingly, most men derive little benefit from the supplements. Often these patients, when they don't get the desired results, being guys, think increasing their dosage by 3 or 4 times would be better. What would be the effects of increasing the testosterone dosage on the following hormone levels? A. Low FSH; high GnRH, LH and estradiol B. Low LH, FSH and estradiol; high GnRH C. Low GnRH, FSH, and LH; high estradiol D. Low GnRH and LH; high FSH and estradiol E. Low estradiol; high GnRH, FSH and LHarrow_forward
