Study Notes
Sexual Hormones and Human Sexuality
- Hormones connect the nervous system and reproductive system.
- Hormones are released by endocrine glands and travel via blood.
- Feedback signals measure hormone levels and compare them to expected levels.
- Organs send feedback signals, including the brain.
Sex Hormones
- Androgens: Develop and maintain masculine characteristics (more prevalent in males).
- Estrogens: Work with progestogens for female sexual and reproductive health (more prevalent in females).
- Progestogens: Create a healthy uterine lining to support a fertilized egg. Synthetic forms are progesterone.
- Oxytocin and vasopressin: Can be considered sex hormones.
Gonadotropic Hormones (Females)
- Follicle Stimulating Hormone (FSH): Important for egg development and stimulating androgens and estrogen. Estrogen inhibits FSH.
- Luteinizing Hormone (LH): Maturing ova, ovulation, stimulating androgens and estrogen. Estrogen stimulates LH.
Gonadotropic Hormones (Males)
- Follicle stimulating hormone (FSH): Helps control sperm production.
- Luteinizing hormone (LH): Binds to cells in testes, causing testosterone secretion.
Hypothalamus and Pituitary
- Hypothalamus: Connects the nervous system to the endocrine system via the pituitary. Highly responsive to sex hormones, influencing individual's perception of sexuality.
- Pituitary: Pea-sized structure, controls other pituitary glands ("master gland").
Menstrual Cycle
- Four phases:
- Follicular: Ovarian follicle matures; estrogen stimulates endometrial growth.
- Ovulation: Mature egg released from ovary.
- Luteal: Endometrium development.
- Menstruation: Endometrial shedding if no conception.
Menopause
- Perimenopause: Years before menopause (late 40s).
- Menopause: Women haven't menstruated in 12 months.
- Symptoms: Hot flashes, sleep disruptions, decreased libido.
