Which of the following is NOT characteristic of menopause?

Menopause begins at age 45 to 50 years old. It is a gradual process which concludes with the cessation of menstruation. Cessation of menstrual flow for a period of one year is considered completion of menopause. Menopause is associated with a marked decline in ovarian estrogen secretion, but adrenal coical estrogens continue to be secreted but are not of sufficient quantity to maintain secondary sexual characteristics. There is a loss of breast tissue, subcutaneous fat, skin elasticity, and body hair as a result of decrease in estrogen supply. There is also systemic vaso instability leading to hot flashes, dizziness, and headaches. The pituitary gland responds to the decrease in estrogen by increasing FSH secretions.
