Testosterone makes us less cooperative and more egocentric


Posted by Dr. Michael White, Updated on January 24th, 2018

Reading Time: 4 minutesScienceDaily (Jan. 31, 2012) — Testosterone makes us overvalue our own opinions at the expense of cooperation, research from the Wellcome Trust Centre for Neuroimaging at UCL (University College London) has found. The findings may have implications for how group decisions are affected by dominant individuals. Problem solving in groups can provide benefits over individual decisions as we are able to share our information and expertise. However, there is a tension between cooperation and self-orientated behaviour: although groups might benefit from a collective intelligence, collaborating too closely can lead to an uncritical groupthink, ending in decisions that are bad for … Read more »

Androgen – Wikipedia, the free encyclopedia


Posted by Dr. Michael White, Updated on January 24th, 2018

Reading Time: 3 minutesAndrogen, also called androgenic hormone or testoid, is the generic term for any natural or synthetic compound, usually a steroid hormone, that stimulates or controls the development and maintenance of male characteristics in vertebrates by binding to androgen receptors.[1] This includes the activity of the accessory male sex organs and development of male secondary sex characteristics. Androgens were first discovered in 1936. Androgens are also the original anabolic steroids and the precursor of all estrogens. The primary and most well-known androgen is testosterone. Dihydrotestosterone (DHT) and androstenedione are less known generally, but are of equal importance in male development. DHT … Read more »

Reading Time: < 1 minuteHypogonadotropic hypogonadism (HH), also known as secondary or central hypogonadism, as well as gonadotropin-releasing hormone deficiency or gonadotropin deficiency (GD), is a condition which is characterized by hypogonadism due to an impaired secretion of gonadotropins, including follicle-stimulating hormone (FSH) and luteinizing hormone (LH), by the pituitary gland in the brain, and in turn decreased gonadotropin levels and a resultant lack of sex steroid production.[1] The type of HH, based on its cause, may be classified as either primary or secondary. Primary HH, also called isolated HH, is responsible for only a small subset of cases of HH, and is characterized … Read more »

Male testosterone levels increase after winning competition with rivals, but not friends

Reading Time: 1 minuteWashington, May 15 (ANI): A new University of Missouri study has found that testosterone levels during group competition are modulated depending on the relationships among the competitors and may be related to the formation of alliances in warfare.

"Our hormonal reactions while competing are part of how we evolved as a cooperative species. What we found in our study is that although male's testosterone levels increase when men are victorious against strangers or rivals, levels of … Read more »

Testosterone – HowStuffWorks

This unfortunate trend has overshadowed the beneficial side of these hormones. Testosterone is a messenger for the body. Like most hormones, it is involved in several different body processes both directly and indirectly. Testosterone levels naturally begin a slow decline around age 30, but several factors can alter this rate. Obesity, for instance, … Read more »
