Study Notes
Hormonal Regulation of the Female Reproductive System
- GnRH initiates the release of LH and FSH from the anterior pituitary gland.
- FSH promotes the development of ovarian follicles.
- LH triggers ovulation.
- Progesterone is responsible for thickening the endometrium.
- hCG maintains the corpus luteum to ensure progesterone production during early pregnancy.
Menstrual Cycle
- The functional layer of the endometrium sloughs off during menstruation.
- The proliferative phase involves the proliferation of the functional layer in response to estrogen.
- The secretory phase is characterized by the maturation and secretion of uterine glands, stimulated by progesterone.
- Progesterone is at its highest level during the secretory phase.
- The LH surge occurs before ovulation, stimulated by increasing estrogen levels.
Female Reproductive Physiology
- Menarche, the onset of puberty in females, is marked by increased GnRH levels.
- Inhibin's primary function is inhibiting FSH secretion.
- The typical menstrual cycle lasts 28 days.
Fertilization and Early Pregnancy
- Fertilization typically occurs in the ampulla of the uterine tube.
- hCG is secreted by the trophoblast after implantation.
Pregnancy and Hormonal Changes
- Progesterone increases rapidly during the latter stages of pregnancy.
- The placenta produces progesterone during the second trimester of pregnancy.
Menopause and Aging
- Menopause is caused by the follicles becoming insensitive to LH and FSH.
- Estrogen and FSH are elevated during menopause.
- Common symptoms of menopause include hot flashes and irritability.
- The uterus shrinks by approximately 25% within 15 years after menopause.
Female Sexual Response
- Both the sympathetic and parasympathetic nervous systems are involved in the female sexual response.
- The physiological changes during the sexual response include clitoral and nipple erection.
- Sperm penetrates the oocyte through capacitation.
Additional Questions
- Progesterone prevents ovulation during pregnancy.
- Progesterone contributes to endometrium hypertrophy during the luteal phase.
