Step by step
Solved in 2 steps
- Match each hormone with its effect. oxytocin a. growth of facial hair testosterone b. uterus contracts LH c. LH, FSH are released GnRH d. surge causes ovulation FSH e. follicle develops HCG f. milk is produced prolactin g. corpus luteum is maintainedFigure 43.15 Which of the following statements about hormone regulation of the female reproductive cycle is false? LH and FSH are produced in the pituitary, and estradiol and progesterone are produced in the ovaries. Estradiol and progesterone secreted from the corpus luteum cause the endometrium to thicken. Both progesterone and estradiol are produced by the follicles. Secretion of GnRH by the hypothalamus is inhibited by low levels of estradiol but stimulated by high levels of estradiol.How is testosterone produced in human males and what are the normal physiological effects of this hormone?
- Which of the significant adverse effects of estrogen-only administration is significantly reduced if a progestin is combined with an estrogen?what is the importance of the female hormone oxytocin? how important is the hormone testosterone for male during puberty age?Name the hormone secreting cells in testis.
- What are the Principal Actions of Estrogen?Equipped with the knowledge about the effects of endocrine disruptors and estrogen, would you recommend hormone replacement therapy for individuals seeking to relieve the symptoms of menopause? Why or why not?estrogen is produced by: hypothalamus, anterior pituitary, the egg, the uterus, or the follicles.?
- What is the relationship between luteinizing hormone (LH), follicle stimulating hormone (FSH) and estrogen.What are the endocrineglands that regulate sexualactivity in males? How doesthis regulation work and whatare the involved hormones?Describe the conversion of testosterone to otherhormones in the sustentacular cells.
