Study Notes
Menopause
- Occurs due to decreased estrogen production and loss of ovarian activity
- Identified by absence of menstruation for six months
- Premature menopause occurs before the age of 40
- Hysterectomy does not affect menopause
- Perimenopause is the period before and after menopause with fluctuating hormones
- Perimenopause usually occurs between 45-55 years old
- Perimenopause causes fluctuating hormones, decreased fertility, mood swings, vasomotor flushes, sleep disturbances
- Increased gonadotropins (LH, FSH) occur due to decreased estrogen and inhibin levels
- Hot flashes are the most common physical complaint of menopausal women
- Estrogen deficiency leads to vaginal dryness, irritation, and dyspareunia
- Osteoporosis in postmenopausal women is caused by decreased estrogen levels, loss of bone matrix and minerals
- Recommended preventative measures for osteoporosis in menopausal women include adequate calcium and protein intake along with physical activity
- Prolonged estrogen intake for more than 10 years is associated with an increased risk of breast cancer
- Excessive estrogen intake can cause endometrial hyperplasia and cancer
Andropause
- Gradual decline in testosterone levels with age in men
- Testosterone declines at a rate of 1% per year after 40
- Low testosterone levels can cause shrinking of the penis and scrotum, decreased facial hair growth, reduced muscle mass and bone density
- DHEAS administration in middle-aged men is associated with prostate enlargement and limited sperm production
- Andropause causes a decrease in muscle mass and strength
Cell Division
- Mitosis is the process of producing two identical diploid cells, for growth and replacement
- Meiosis is the process of cell division that produces four unique haploid cells for sexual reproduction
Spermatogenesis
- Process of forming sperm in the seminiferous tubules of the testes
- Meiosis I results in two haploid secondary spermatocytes
- Spermiogenesis is the transformation of spermatids into mature sperm
Oogenesis
- Process of forming eggs in ovaries
- Resumption of meiosis in primary oocyte is triggered by a surge in LH before ovulation
- One oogonium produces one mature ovum
