- What conclusion can you draw regarding the relationship between the thickness of the endometrium and the hormone level of progesterone?Describe the hormonal control of spermatogenesis in terms of the hypothalamic-pituitarygonadal axis (HPG axis) – in this case, the hypothalamic-pituitary-testes axisList the anabolic and androgenic effects of testosteroneUnlike male gonadotropins, female gonadotropins are able to promote the development of a single optimal dominant follicle during most cycles with the release of a single gamete from an LH surge and then optimization of the uterine environment for implantation. To understand pathologies in this complex system, one must understand the ideal steps within the normal menstrual cycle. Which of the following statements best describes the role of FSH in menstruation? O FSH induces granulosa cell LH receptors within the dominant follicle. O FSH stimulates follicular growth only in the early preantral stage. ( ) FSH stimulates granulosa cell androgen production. O FSH increases its own receptor numbers on theca cells. O FSH induces theca cell aromatase.
- The release of FSH and LH from gonadotropes in the anterior pituitary is separately controlled by the same hypothalamic releasing hormone, GNRH. How is it possible to organize their secretion during the menstrual cycle?Sildenafil citrate (marketed under the name ‘Viagra’) causes increased blood flow into the penis, thus allowing for erection to occur. Explain the mechanism by which this drug accomplishes this? What hormone is primarily responsible for the Graafian follicle rupturing to release the oocyte at ovulation?What role does pituitary gonadotrophins play during follicular and ovulatory phases of menstrual cycle and also explain the shift steroidal secretions.
- hCG, estrogen and progesterone are hormones that are secreted throughout pregnancy. Answer the following questions about these hormones. 1) What structure initially secretes estrogen & progesterone? 2)What structure takes over the role of secreting hCG, estrogen & progesterone in the second and third trimesters?Which of the following statement does NOT describe the role of progesterone in the female reproductive system? Select one: A. Prevent the shedding of the endometrium B. Ensures that the endometrium is thick enough to support a fertilized egg C. Trigger the thickening of the endometrium D. Prevent smooth muscle construction, thereby preventing premature birthWhat are the organizing effects of sex hormones? Compare the negative feedback loops in the male reproductive system with those of the female’s reproductive cycle. Describe an example of positive feedback involving estrogen that leads to ovulation. What are the hormonal changes during the luteal phase of the menstrual cycle?
- Describe how the hypothalamic-pituitary-gonadal axis regulates gamete production in males and females. Give the hormones from each gland that are secreted in this process.Clomiphene Citrate is a fertility drug that stimulates hypothalamic secretion of Gonadotropin releasing Hormone (GnRH) in females and induces ovulation. Explain how increased GnRH with Clomiphene Citrate treatment would affect follicle maturation and ovulation in women (explain how increased GnRH would affect FSH, LH, Estrogen, and ovulation).Use the following information to answer the following question.The onset of labour both at term and preterm is associated with a functional withdrawl of progesterone activity at the level of the uterus. One method that can be used to reduce preterm labour is to supplement with synthetic progesterone.(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3218546/)Progesterone supplementation may help to prevent preterm delivery by Select one: a. increasing levels of FSH b. decreasing the endometrium c. calming uterine contractions d. decreasing levels of estrogen
