Males with elevated levels of testosterone lead shorter lives but have more success siring offspring

Comparative studies have studied testosterone levels and related them to mating systems and aggression, but very few studies have attempted to relate testosterone to fitness, that is, the combination of lifetime reproductive success and survival, in the wild or experimentally. Over nine breeding seasons, Wendy Reed (North Dakota State University) and her colleagues followed a group of dark-eyed j...

Sleep quantity affects morning testosterone levels in older men

The testosterone levels of healthy men decline as they get older. As sleep quality and quantity typically decrease with age, objectively measured differences in the amount of sleep a healthy older man gets can affect his level of testosterone in the morning, according to a study published in the April 1st issue of the journal SLEEP. The study, conducted by Plamen Penev, MD, PhD, of the Un...

ASU research shows connection between testosterone, dietary antioxidants and bird coloration

In a new physiological study of birds, a researcher at Arizona State University has found that carotenoids, the pigments that color carrots orange and corn yellow, have even deeper health benefits than originally thought. They appear to fight off the negati...

Low testosterone levels lead to eating disorders

The researchers suspect low testosterone levels in men suffering from eating disorders. Men who suffer from eating disorders can be affected more than women with the same problems, researchers say.// Eating disorders are associated with a weakening of the bones, which become dangerously thin and brittle. This is linked to severe weight loss and lack of essential nutrients, particula...

Decrease in testosterone levels lead to Alzheimer's

Suppression of testosterone levels in men with testicular cancer may inadvertently increase the risk of Alzheimer’s disease, warn US researchers.A research team from North Carolina University has found that when circulating testosterone levels go down, a high rise in levels of amyloid – the protein implicated in Alzheimer’s disease – occurs. They suggest that this phenomenon might explain why...

Testosterone Replacement Therapy Safe If Monitored Appropriately

About 2 million to 4 million men in the United States have low levels of testosterone. Symptoms of the condition // may include erectile dysfunction, reduced muscle mass, reduced bone density, depression, and anemia. Testosterone replacement therapy is designed to increase testosterone levels for men with the condition. The therapy may be offered as an injection, patch, gel, or tablet. N...

Low Testosterone Levels the Cause Of Depression In Men

Testosterone deficiency, or hypogonadism, is a common problem among men as they age. About 30 percent of // all males over age 50 suffer from the condition to some degree, with symptoms ranging from diminished appetite, fatigue, and decreased libido to irritability, decreased muscle mass and strength, and decreased bone mineral density. Many of these symptoms also play a role in depression, but s...

The Use Of Testosterone Replacement Therapy Questioned

Symptoms of low levels of testosterone include erectile dysfunction, reduced muscle mass, reduced bone density, depression, and anemia.// Testosterone replacement therapy is designed to increase testosterone levels for men with the condition. The therapy may be offered as an injection, patch, gel, or tablet. New research shows testosterone replacement therapy does not increase a man’s risk of dev...

Testosterone EIA Reproductive Markers 020-DR-1559

Description:Testosterone is the most important androgen secreted into the blood. In males, testosterone is secretedprimarily by the Leydig cells of the testes; in females ca. 50% of circulating testosterone is derived fromperipheral conversion of androstenedione, ca. 25% from the ovary and ca. 25% from the adrenal glands. The Testosterone ELISA KIT is based on the competition principle and the micropla...

Free Testosterone EIA Test

Description:Only 1-2% of circulating testosterone exists as unbound or free testosterone. The majority, approximately 60%, is bound to SHBG with high affinity [1], while the remainder is loosely bound to albumin. Both the albumin-bound and free fractions may be biologically active, while SHBG effectively inhibits testosterone action. Measurement of the free or unbound fraction of serum testosterone has been...

Testosterone EIA Test

Description:Testosterone, (17-Hydroxy-4-androstene-3-one), a C19 steroid, is one of the most potent naturally secreted androgens [1]. In postpubertal males, testosterone is secreted primarily by the testes with only a small amount derived from peripheral conversion of androstenedione [2]. In adult women, it has been estimated that over 50% of serum testosterone is derived from peripheral conversion of andros...
