    Study Notes

    Reproductive System - Advanced

    • Question 1: Spermatogonium produces 4 spermatozoa.

    • Question 2: Progesterone's main role during the luteal phase is preparing the endometrium for embryo implantation.

    • Question 3: Cholesterol is the precursor for all sex hormones.

    • Question 4: Sertoli cells (sustentacular cells) do not secrete androgens. They maintain the blood-testis barrier and secrete inhibin and androgen-binding protein.

    • Question 5: Testosterone levels are highest during puberty.

    • Question 6: The main stimulus for ovulation is release of luteinizing hormone (LH) from the pituitary gland.

    • Question 7: The correct order of follicle development is primary oocyte – primary follicle – mature follicle – corpus luteum – ovulation.

    • Question 8: During menstruation, both estrogen and progesterone levels fall.

    • Question 9: Inhibin inhibits the release of follicle-stimulating hormone (FSH) from the pituitary gland.

    • Question 10: Testosterone has a significant effect on skeletal muscle growth.

    • Question 11: During the early stages of pregnancy, the corpus luteum secretes human chorionic gonadotropin (hCG).

    • Question 12: In the follicular phase, the ovary is maturing a follicle.

    • Question 13: The luteal phase of a 30-day ovarian cycle is 14 days long.

    • Question 14: Blocking progesterone receptors in the uterus will likely inhibit endometrial development.

    • Question 15: Home-use fertility kits measure human chorionic gonadotropin (hCG).

    • Question 16: Testosterone is primarily produced by Leydig cells in human males.

    • Question 17: A key difference between male and female gamete production is that males produce many gametes continually, females produce only one gamete at a time.

    • Question 18: The acidic pH of the vagina helps prevent infections.

    • Question 19: Blockage of both uterine tubes leads to sterility.

    • Question 20: A deep voice is a male secondary sexual characteristic, not an increased incidence of acne.
