- 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.arrow_forwardWhich of the following is correct pairing of concepts? * A. Male sex hormones: androgens B. Pregnancy hormones: progestins C. Female sex hormone: estrogen D. After menopause hormones: estriolarrow_forwardThe 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?arrow_forward
- A 38-year-old male is upset about his low sperm count and visits a “practitioner” who commonly advertises his miracle cures for sterility. In fact, the practitioner is a quack who treats conditions of low sperm count with megadoses of testosterone.

The practitioner is a quack who treats conditions of low sperm count with megadoses of testosterone. Although his patients experience a huge surge in libido, their sperm count is even lower after hormone treatment. a) Which two glands would be responsive to the megadose of testosterone? b) Identify the two hormones that would be affected by the megadose of testosterone. Would their levels increase or decrease? c) What role, if any, would either of the affected hormones have on the man's reduced sperm count?arrow_forwardWhat is the purpose of androgen binding protein by Sertoli cells of the testes? a. Potentiates the actions of testosterone at target cells b. Prevents testosterone from diffusing out the testes c. Regulates level of testosterone via negative feedback control at the level of the anterior pituitary d. To stimulate testosterone productionarrow_forward
- Which of the following statements does NOT describe the role of progesterone in the female reproductive system? a. Triggers the release of the ovum b. Prevents smooth muscle contraction, thereby preventing premature birth c. Prevents the shedding of the endometrium d. Ensures that the endometrium is thick enough to support a fetilized eggarrow_forwardFigure 18.17 Which of the following statements about hormone regulation of the female reproductive cycle is false?a. LH and FSH are produced in the pituitary, and estrogen and progesterone are produced in the ovaries.b. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken.c. Both progesterone and estrogen are produced by the follicles.d. Secretion of GnRH by the hypothalamus is inhibited by low levels of estrogen but stimulated by high levels of estrogen.arrow_forwardExplain Briefly Compare and contrast the role of hormones that causes changes to the male and female reproductive system when a male and a female reaches puberty stage.arrow_forward
