Questions and Answers

What is the function of luteinizing hormone (LH) in the female reproductive system?

LH causes ovulation, which is the release of an egg from the ovary. It also results in the formation of a corpus luteum.

Which of the following hormones is responsible for stimulating the production of estrogen in the female reproductive system?

  • LH (correct)
  • GnRH
  • Estrogen
  • FSH (correct)

    • The corpus luteum continues to function even if fertilization does not occur.

    False

    What is the primary function of the hormone progesterone in the female reproductive system?

    <p>Progesterone thickens the uterine lining (endometrium), providing a suitable environment for a fertilized egg to implant and grow.</p> Signup and view all the answers

    What is the function of GnRH in the male reproductive system?

    <p>GnRH signals the Pituitary gland to release FSH and LH.</p> Signup and view all the answers

    What is the difference between the ovarian cycle and the menstrual cycle?

    <p>The ovarian cycle refers to the events occurring in the ovaries, including the development and release of eggs. The menstrual cycle refers to the changes in the uterine lining, starting with menstruation (shedding of the lining) and ending with the thickening of the lining in preparation for a potential pregnancy.</p> Signup and view all the answers

    Why is it not advisable for women nearing menopause to get pregnant?

    <p>Women nearing menopause have a higher risk of complications during pregnancy, such as miscarriage, premature birth, or health problems for both the mother and the baby.</p> Signup and view all the answers

    Why is an ectopic pregnancy, where a fertilized egg implants in the fallopian tube, dangerous for the mother?

    <p>An ectopic pregnancy is dangerous because the fallopian tube cannot support a growing fetus. The fertilized egg can cause the fallopian tube to rupture, leading to severe internal bleeding and potentially life-threatening complications for the mother.</p> Signup and view all the answers

    Study Notes

    Coordinated Functions of Reproductive, Endocrine, and Nervous Systems

    • The reproductive, endocrine, and nervous systems work together to regulate male reproductive functions.
    • GnRH (gonadotropin-releasing hormone) is secreted by the hypothalamus.
    • GnRH stimulates the pituitary gland to release FSH (follicle-stimulating hormone) and LH (luteinizing hormone).
    • LH stimulates testicular cells to secrete testosterone.
    • FSH, along with testosterone, stimulates sperm production in the seminiferous tubules.
    • High testosterone levels inhibit GnRH secretion.

    Hormones in Male Reproductive System

    • Gonadotropin-releasing hormone (GnRH) is released by the hypothalamus.
    • The hypothalamus signals the pituitary gland to release FSH and LH.
    • FSH and LH affect the testes.
    • LH stimulates testosterone production.
    • FSH and testosterone stimulate sperm production in the seminiferous tubules.
    • High testosterone levels inhibit GnRH release.

    Hormones in Female Reproductive System

    • The hypothalamus releases GnRH, which signals the pituitary gland to release FSH and LH.
    • FSH stimulates follicular growth in the ovaries, which causes estrogen secretion.
    • LH causes ovulation and the formation of a corpus luteum, resulting in progesterone production.
    • Estrogen thickens the uterine lining (endometrium) and inhibits FSH and LH release for most of the cycle.
    • Progesterone also thickens the uterine lining and inhibits FSH and LH.

    Menstrual Cycle

    • The cycle typically lasts 28 days, but lengths vary.
    • The menstrual cycle involves phases like menstruation, the proliferative phase (uterine lining thickens), ovulation, and the secretory phase (further uterine lining thickening).
    • Ovulation usually occurs around day 14.
    • The cycle includes the ovarian cycle and uterine cycle.

    Ovarian Cycle

    • The ovarian cycle involves the growth and release of an egg (ovum).
    • The cycle involves the phases of follicular phase, ovulation, and luteal phase, where the corpus luteum develops.
    • Hormonal changes, like estrogen and progesterone, drive the ovarian cycle.

    Feedback Mechanisms

    • Feedback mechanisms regulate processes in the reproductive system.
    • High estrogen levels in the bloodstream can inhibit GnRH production.
