    Study Notes

    Reproductive System Overview

    • Male and female reproductive systems consist of primary sex organs (gonads) that produce gametes and secrete steroid sex hormones.
    • Male gonads: testes produce sperm and androgens.
    • Female gonads: ovaries produce ova and secrete estrogens and progesterone.
    • Accessory reproductive organs include ducts, glands, and external genitalia.

    Male Reproductive System Anatomy

    • Testes are sperm-producing gonads located within the scrotum.
    • Sperm travels through ducts: epididymis, ductus deferens, ejaculatory duct, and urethra.
    • Accessory glands include seminal vesicles, prostate, and bulbourethral glands.

    Spermatogenesis

    • Defined as the production of sperm in seminiferous tubules.
    • Most body cells are diploid with 46 chromosomes; gametes are haploid with 23 chromosomes.
    • Meiosis involves two cell divisions, resulting in four genetically diverse daughter cells.

    Meiosis vs. Mitosis

    • Meiosis: two rounds of division (meiosis I & II) with one DNA replication.
    • Involves genetic diversity as daughter cells are different from the original cell.
    • During mitosis, daughter cells remain diploid, while meiosis results in haploid cells.

    Female Reproductive System Anatomy

    • Includes structures such as ovaries, uterine tubes (fallopian tubes), uterus, and vagina.
    • Ovaries are connected by suspensory ligaments and produce eggs and hormones.
    • Uterus comprises three layers: endometrium (inner), myometrium (middle), and perimetrium (outer).

    Uterine (Menstrual) Cycle

    • Days 1-5: Menstrual phase, shedding of the functional layer of the endometrium.
    • Days 6-14: Proliferative phase where estrogen levels rise, thickening the endometrial lining.
    • Days 15-28: Secretory phase, endometrium prepares for embryo implantation following ovulation.
    • If no fertilization occurs, the corpus luteum degenerates, leading to the next menstrual cycle.

    Hormonal Regulation

    • Rising estrogen levels stimulate endometrial growth and the synthesis of progesterone receptors.
    • Progesterone from the corpus luteum maintains uterine lining for potential implantation.
    • Cervical mucus changes consistency to facilitate sperm passage during ovulation.
