Menopause is the permanent cessation of menses resulting from diminishing ovarian follicular function.
It is defined as 12 consecutive months of amenorrhea.
What is the median age of onset in the US for menopause?
Median age of onset is 51 years of age (range 40-55).
Perimenopause, also called the menopausal transition, is the time before menopause and the first year following menopause.
Ovarian function and production of estrogen decline during this time, and menstrual cycles may be irregular.
Symptoms of perimenopause related to declining estrogen
- Abnormal uterine bleeding
- Extended menstrual cycle intervals
- Anovulation is a condition in which the ovary does not release a ripened egg each month as part of a woman's normal cycle in her reproductive years.
- Naturally, with no egg available for sperm, a woman cannot become pregnant.
- Oligomenorrhea (or oligomenorrhoea) is infrequent or very light menstruation.
- More strictly, it is menstrual periods occurring at intervals of greater than 35 days, with only four to nine periods in a year.
What are the three (3) V's symptoms of menopause directly related to lack of estrogen
- Vaginal dryness
- Vaginal atrophy (atrophic vaginitis) - is thinning and inflammation of the vaginal walls due to a decline in estrogen
- Vasomotor symptoms - night sweats, hot flashes
Symptoms associated with menopause, but without link to estrogen deficiency
- mood swings
- urinary frequency
- cognitive changes (memory & concentration loss)
Pathophysiology of menopause
- 1. Loss of ovarian follicular activity
- 2. Ovarian production of estradiol & progesterone diminishes
- 3. FSH & LH concentrations increase
- 4. Primary estrogen available is now estrone (which is converted peripherally from androstenedione & is less potent), not estradiol

What is the most effective therapy for moderate to severe vasomotor symptoms related to menopause?

- Estrace® (Estradiol)
What are the common side effects of estrogen derivatives?
- Breast tenderness
- Heavy/irregular bleeding

Patient instructions & counseling on the uses of estrogen & progestin
- Patients should be instructed to immediately report any unusual vaginal bleeding
- Patients should be instructed to contact their PCP promptly for any ACHES symptoms
Which method can be used to diminish the hypertriglyceride effect caused by estrogen?
Switch to a transdermal product
What are the precursor hormones to estrogen production by the ovaries & peripheral site?
Ovarian testosterone production declines with menopause.
When can testosterone therapy be initiated in postmenopausal women?
women who are receiving concurrent estrogen therapy
What are the three (3) contraindications to androgens therapy?
- androgenic alopecia
What are the SEs of androgens?
- fluid retention
