Study Notes
Female Reproductive System
- The female reproductive system includes ovaries, uterine tubes, uterus, vagina, and external genitalia.
- Ovaries produce oocytes and hormones.
- Uterine tubes transport fertilized eggs to the uterus.
- The uterus is where fetal development occurs.
- The vagina is the birth canal and organ of copulation.
- External genitalia are the vulva, including the mons pubis, labia majora, labia minora, clitoris, and vestibular glands.
Ovaries
- Paired organs, almond-shaped, located in the upper pelvic region.
- Held in place by ligaments (ovarian, suspensory, mesovarium).
- Contains ovarian follicles (structures containing oocytes in various developmental stages).
- Oocytes are immature eggs.
- Tunica albuginea is a capsule of dense connective tissue.
- Cortex contains follicles, follicles contain oocytes in various stages of development, surrounded by supporting cells.
- Medulla is deeper region composed of connective tissue, blood vessels and lymphatics.
- Germinal epithelium covers the ovary (visceral peritoneum).
Uterine Tubes (Fallopian Tubes)
- Narrow, 10cm tubes extending from ovaries to uterus.
- Composed of isthmus (narrow), ampulla (wide), and infundibulum.
- Fimbriae (finger-like processes) sweep oocytes into the uterine tubes.
- Zygote (fertilized egg) moves towards uterus.
- Implantation occurs approximately 6 days after fertilization.
Uterus
- Central organ for fetal development, composed of fundus, body, and cervix.
- Has uterine cavity, connected to vagina via cervical canal.
- Supported by mesosalpinx, mesovarium, mesometrium, utero-sacral ligaments, lateral cervical ligaments.
Vagina and External Genitalia (Vulva)
- Birth canal and organ of copulation, extending between bladder and rectum from cervix to exterior.
- Vulva includes mons pubis (fatty area), labia majora (hair-covered fatty folds), labia minora (skin folds), clitoris, and vestibular glands (erectile tissues).
Hormonal Control
- Hormonal control of the cycles involves gonadotropin-releasing hormone (GnRH) from the hypothalamus, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) from the anterior pituitary, estrogen, and progesterone.
- GnRH stimulates FSH & LH release.
- FSH drives follicle development, granulosa cells produce estrogen & inhibin.
- LH stimulates thecal cells to produce androgens, converted to estrogen.
- Estrogen affects uterine regeneration.
- LH stimulates ovulation & corpus luteum formation, progesterone produced (ovary).
- Progesterone prepares uterus for implantation.
Oogenesis & Folliculogenesis
- Oogenesis is the production of oocytes (immature eggs). Occurs before birth (2n = 4 chromosomes). Primary oocytes arrest during prophase I (2n). Continues monthly from puberty to menopause.
- Folliculogenesis is the overall development of ovarian follicles.
Ovarian Cycle
- Monthly cycle of changes in the ovary.
- Development of follicles culminates in ovulation.
- Follicular phase: development & maturation of follicles, increasing estrogen.
- Ovulation: release of mature egg from follicle.
- Luteal phase: formation of corpus luteum, progesterone & estrogen production.
Uterine Cycle
- Monthly cycle of changes in the uterine lining (endometrium).
- Preparing for potential pregnancy.
- Menstrual phase: uterine lining sheds (no pregnancy).
- Proliferative phase: uterine lining builds up under estrogen influence.
- Secretory phase: uterine lining is prepared for implantation (progesterone from corpus luteum).
Fertilization
- Ovulation occurs ~14 days after menstruation.
- Egg survives approximately 1 day.
- Sperm can survive ~3 days in the female reproductive tract.
