Male & Female HRT Risks, Successes, the Future?
Teresa Bailey, PharmD, BCPS, BCACP, FCCP
June 2015
Objectives
 Explain the association of testosterone therapy with mortality, myocardial infarction,
and stroke in men with low testosterone levels.
 Discuss the potential benefits of hormone replacement therapy in women
 Discuss the pros and cons of dehydroepiandrosterone for peri- and postmenopausal
women.
Pathophysiology
 Menopause
o Loss of ovarian function leading to a state of permanent amenorrhea
o Ovaries no longer able to respond to pituitary stimulating hormones, so estrogen levels
are low and production of FSH and LH increases dramatically.
o Average age of onset-51.4 years
o Onset unaffected by: race, socioeconomic status, alcohol consumption, age of
menarche, or age of last pregnancy. Cigarette smoking may accelerate onset up to 2
years because of gametotoxic effects of cigarette smoke on steroid hormone
metabolism by liver.
o Premature menopause-loss of ovarian function before the age of 35 years due to
ovarian surgery, endocrinologic, autoimmune disorders

Estrogen and Progestin Therapy
Benefits and Risks of Estrogen and Progestin Therapy (Ann Intern Med 1992;117(12):10381041)
Benefits
Estrogen
1. Relieves genitourinary atrophy
Thinning of hair of the mons and
shrinkage of the labia minora
Atrophy of vulva leads to pruritus and pain
Vaginal pH 4.55  68 creating a
favorable environment for bacterial
colonization
Loss of lubrication  dyspareunia
Recurrent episodes of urinary frequency
and urgency with dysuria
2. Relieves vasomotor instability
Occurs in 75%–85% of women.
Occurs usually within 12–24 months after
the last menstrual period.
Increased skin temperature, nausea,
dizziness, headache, palpitations,
diaphoresis, night sweats.
3. Osteoporosis-Reduction of hip fractures by
25%. Reduction of vertebral fractures by
50%. Estrogen reduces rate of resorption
but does not restore bone loss.
Progestin
1. Decrease risk of estrogen-induced
irregular bleeding, endometrial
hyperplasia, and carcinoma
2. Protection against breast carcinoma
3. Enhancement of estrogen prophylaxis
of osteoporosis
4. Lowers LDL cholesterol by 11% and
increases HDL cholesterol by 10%.
However, was not shown to lower
coronary heart disease based on HERS
trial.
5. Increase in life expectancy
6. Insomnia and fatigue
7. Mood changes
8. Sexual function
Risks
Estrogen
1. Endometrial cancer by unopposed estrogen.
Duration of estrogen use dependent; eightfold for 10–20 years of use.
Recommended not to use in women with a
history of endometrial cancer.
2. Breast cancer with unopposed estrogenuncertain. May increase slightly (25%)
among women who take estrogen for
1020 years. Recommended not to use in
women with a history of breast cancer.
3. Increased risk of cardiovascular outcomes.
(See WHI trial).
4. Adverse effects: bloating, headache, breast
tenderness (5–10%)
5. Unpredictable uterine bleeding with
unopposed estrogen (35–40%)
Progestin
1. Adverse effects: bloating, weight gain,
irritability, depression. (Dose related)
2. Unpredictable endometrial bleeding with
continuous estrogen/progestin during
first 8–12 months (30–50%)

Low Testosterone Levels. JAMA 2013:310:1829-1836
o Retrospective, cohort study
o 23,173 male veterans underwent coronary angiography and had testosterone level checked

o Association between TT with all-cause mortality, myocardial infarction, stroke
o N = 8,709 men with Testosterone level < 300 ng/dL with or without CAD

o
Primary endpoint
 Combined end point of time to all-cause mortality or to hospitalization for MI or
ischemic stroke
 HR = 1.29 (CI, 1.05-1.58)
 Regardless of presence of CAD
•
AUA Position Statement
o Potential for misuse of testosterone for non-medical indications, such as body building or
performance enhancement
o Testosterone therapy appropriate treatment for hypogonadism after full discussion of potential
adverse effects
o Testosterone therapy in the absence of hypogonadism not appropriate
•

practice guideline. J Clin Endocrinol Metab. 2010 Jun;95(6):2536-59
o Treatment of androgen deficiency with testosterone
o Men with sexual dysfunction
o Patients with chronic illness and low testosterone levels
o Glucocorticoid-treated men
o Older men with low serum testosterone concentration-not recommended
•
Conclusion
o Risks may outweigh the benefits for
 Estrogen/progestin therapy
 Testosterone replacement therapy
 DHEA
o Studies lacking
 Bioidentical hormones
