Which of the following statements accurately describes the pathogenesis of polycystic ovarian syndrome?
Question 28 options:
a)
Excessive androgens that affect follicular decline by suppressing apoptosis, enabling follicles, which normally disintegrate to survive
b)
A decrease in leptin levels that reduces the hypothalamic pulsatility of GnRH, which reduces the number of follicles that mature
c)
A disorder of the anterior pituitary that increases the release of FSH, which reduces the release of LH
d)
Testosterone that stimulates androgen secretion by the ovarian stroma and reduces SHBG indirectly
What happens if an oocyte combines with sperm? Describe the processes involved in implantation. Mention what is occurring, where it is occurring, and any significant hormones involved. How does the zygote make its way through the uterine tube? Women who smoke cigarettes have an increased risk of ectopic pregnancy because the chemicals they absorb paralyze cilia all through the body. Explain.
At the end of the uterine cycle, there is a significant drop in the levels of LH, estrogen, and progesterone.This causes all of the following EXCEPT
Select one:
a. an increase in smooth muscle contractions of the uterus
b. the start of menstruation, which breaks down the blood vessels and tissues formed during the follicular stage
c. the maintenance of the corpus luteum to continue producing low levels of progesterone and estrogen
d. a negative feedback loop to the pituitary to secrete more FSH and LH

If not treated, it can cause pelvic inflammatory disease (PID) in women and epididymitis in men. PID can cause scar tissues in the structure responsible for transporting the fertilized egg and in the tissue that is maintained by progesterone during a menstrual cycle, leading to infertility. In the diagram above, the structures associated with PID for the effects described above are numbered Select one: a. 1, which is the Fallopian tube, and 3, which is the endometrium, respectively b. 1, which is the Fallopian tube, and 4, which is the endometrium, respectively c. 4, which is the uterus, and 6, which is the cervix, respectively d. 3, which is the uterus, and 7, which is the cervix, respectivelyarrow_forward

A spermatozoon can survive for more than five days in a female reproductive tract. C) The proliferative endometrial phase is promoted by progesterone. Synthetic estrogens act as contraceptives by preventing the ovarian luteal phase. The hormonal basis of stress-induced amenorrhea is due to the influence of the limbic system on GNRH secretion.arrow_forwardSloughing of the functional layer of the endometrium occurs because of: A) Increasing estrogen C ) Decreasing progesterone levels D ) Increasing progesterone levelsarrow_forward

- One of the common unfortunate consequences of a vasectomy is that the proximal ends of the ductus deferens rupture and spermatozoa are exposed to the immune system. The person with the testes then produces antibodies against their own sperm. This has consequences for the effectiveness of a vasectomy reversal. In the situation described above, why are the spermatozoa considered foreign even though they are being produced within the person’s own seminiferous tubules? This immune response is not normal, and so describe how the testes’ structure prevents this immune reaction from occurring.arrow_forwardMumps is a viral infection. The primary symptom of mumps is visible swelling of the parotid gland on either side of the face. However, the virus can also infiltrate the male reproductive system, causing the testes to atrophy.
