Osteoporosis in Men

Testosterone and Estradiol Deficiency
Researchers writing in the Journal of Clinical Endocrinology & Metabolism say that: Older men with total testosterone or estradiol deficiency were more likely to be osteoporotic. Those with osteoporosis were more likely to be total testosterone or estradiol deficient. Rapid hip bone loss was more likely in men with total testosterone deficiency.

Fink HA, Ewing SK, Ensrud KE, Barrett-Connor E, Taylor BC, Cauley JA, Orwoll ES. Association of Testosterone and Estradiol Deficiency with Osteoporosis and Rapid Bone Loss in Older Men. J Clin Endocrinol Metab. 2006 Jul 18

From the article abstract:
Context: The clinical value of measuring testosterone and estradiol in older men with osteoporosis and of measuring bone mineral density (BMD) in older men with testosterone or estradiol deficiency is uncertain.

Objective: To examine the association of testosterone and estradiol deficiency with osteoporosis and rapid bone loss in older men.

Participants: 2447 community-dwelling men aged >/=65.

Main Outcome Measures: Total testosterone deficiency defined as <200 ng/dl.

Total estradiol deficiency defined as <10 pg/ml.

Results: Prevalence of osteoporosis in men with deficient and normal total testosterone was 12.3% and 6.0% (P = 0.003), and in those with deficient and normal total estradiol was 15.4% and 2.8% (P < 0.0001).

Among osteoporotic men and those with normal BMD, prevalence of total testosterone deficiency was 6.9% and 3.2% (P = 0.01) and prevalence of total estradiol deficiency was 9.2% and 2.4% (P = 0.0001). Incidence of rapid hip bone loss in men with deficient and normal total testosterone was 22.5% and 8.6% (P = 0.007), and in those with deficient and normal total estradiol was 14.3% and 6.3% (P = 0.08).

Conclusions: Older men with total testosterone or estradiol deficiency were more likely to be osteoporotic. Those with osteoporosis were more likely to be total testosterone or estradiol deficient. Rapid hip bone loss was more likely in men with total testosterone deficiency. BMD testing of older men with sex steroid deficiency may be clinically warranted.

Bone Loss

Estradiol, Testosterone, and Hip Fractures in Men
Researchers writing in The American Journal of Medicine say “Men with low estradiol levels are at an increased risk for future hip fracture. Men with both low estradiol and low testosterone levels seem to be at greatest risk for hip fracture.”

The Importance of Strength Training Exercises in Aging
Researchers writing in the medical journal Aging Clinical and Experimental Research say that “although aerobic exercise is important in maintaining overall health, the resistance type of muscle training may be more applicable to the basic rules of bone adaptation and site-specific effects of exercise, have more favorable effects in maintaining or improving bone mass and architecture, and be safe and feasible for older people.”

DHEA, Bone Mineral Density, Older Adults
Researchers writing in the medical journal The Journal of Clinical Endocrinology & Metabolism, say that DHEA replacement therapy for one year improved hip Bone Mineral Density in older adults and spine Bone Mineral Density in older women.

Lifelong risk factors for osteoporosis and fractures in elderly women with low body mass index
Researchers writing in the medical journal Bone, evaluated the association between lifelong lifestyle factors and bone density, falls and postmenopausal fractures in elderly women with low body mass index.

Osteoporosis in Men Testosterone and Estradiol Deficiency
Researchers writing in the Journal of Clinical Endocrinology & Metabolism say that: Older men with total testosterone or estradiol deficiency were more likely to be osteoporotic. Those with osteoporosis were more likely to be total testosterone or estradiol deficient. Rapid hip bone loss was more likely in men with total testosterone deficiency.

Hip Fracture in High Risk Groups
Researchers writing in the Journal of Postgraduate Medicine say “prevention of hip fracture is still inadequate in high risk patients. Discrepancy seemed to exist in treatment frequency among different high risk groups suggesting that emphasis on prevention of osteoporosis has not been reinforced in all people at risk.”

Sleep and Risk of Fractures
Researchers writing in the Journal of the American Geriatrics Society say that long sleep and daily napping are associated with greater risk of falls and fractures in older women

Postmenopause and Periodontal Disease

A recent study in the Journal of Periodontology says that in an 11.7 year follow up, 57.5 percent of women lost at least one tooth after menopause.

Bone loss is to blame!

The American Academy of Periodontology’s press release on this study says “Estrogen deficiency after menopause and consequent loss of bone mineral density have been shown to be associated with increased rate of tooth loss. These relationships may be explained by increased severity of periodontal disease in estrogen deficiency.”

Low Testosterone and the Pro-Inflammatory State in Aging Men

Researchers writing in the Journal of Endocrinological Investigation “suggest that a close relationship exists between the development of a pro-inflammatory state and the decline in Testosterone levels” and that “observational and interventional studies suggest that Testosterone supplementation reduces inflammatory markers in both young and old hypogonadal men. ”

Testosterone’s Favorable Effects on an Important Metabolic Component of Chronic Heart Failure

Researchers writing in the European Journal of Heart Failure say that testosterone improves fasting insulin sensitivity in men with chronic heart failure and may also increase lean body mass, these data suggest a favorable effect of testosterone on an important metabolic component of CHF.

Researchers in Sweden writing in the Journal of Bone and Mineral Research, say “not only estrogens but also androgens are of importance for bone health in elderly men.”

Older Men and Testosterone
From the study abstract: “Male hypogonadism is a clinical situation characterized by a low serum testosterone level in combination with a diversity of symptoms and signs such as reduced libido and vitality, decreased muscle mass, increased fat mass and depression.

Testosterone replacement therapy and the risk of prostate cancer
The article says “The belief that testosterone increases the risk of prostate cancer is so widely accepted that study after study that tries to show it and can’t keeps getting repeated over and over,” says Dr. Abraham Morgentaler, a Boston urologist and author of the 2004 review. “People don’t believe it.”
