For example, problem with function of pituitary gland or adrenal glands may lead to reduced testosterone production. The testes produces less testosterone, there are fewer signals from the pituitary telling the testes to make testosterone. In recent years, researchers (and pharmaceutical companies) have focused on the effects of testosterone deficiency, especially among men. One treatment available for many of these problems is spironolactone, a special type of diuretic (water pill) that blocks the action of male sex hormones. The ovaries of women with PCOS contain multiple cysts. Having too much naturally-occurring testosterone is not a common problem among men. Testosterone levels are too carefully controlled by the brain for that to occur. Testosterone is a major influence on bodily and behavioral features seen as male and/or masculine. However, our experiment demonstrates that gender-related social factors also matter, even for biological measures. But the way it’s being promoted to healthy men is highly misleading. Overwhelmingly now, when it comes to health and wellness, people are there to sell you things, and they’ll say, do and look however they need to." Influencers are now an established part of medical marketing and Nickel urges consumers to be sceptical. Some men and women experience immediate side effects of testosterone treatment, such as acne, disturbed breathing while sleeping, breast swelling or tenderness, or swelling in the ankles. However, the wisdom and effectiveness of testosterone treatment to improve sexual function or cognitive function among postmenopausal women is unclear. As surprising as it may be, women can also be bothered by symptoms of testosterone deficiency. For example, a man with osteoporosis and low testosterone can increase bone strength and reduce his fracture risk with testosterone replacement. Mean gender self-ratings on femininity and masculinity subscales (41, 42) by condition (neutral control, masculine, and feminine), with SE bars. Because gender norms encourage more competition for men and less for women (10, 24), men could actually show dampened testosterone responses to individual competitive events because of their higher rate of engagement in them. Recent theory predicts that competition and holding power, rather than masculinity per se, increases testosterone (3). Using a novel experimental design, participants (trained actors) performed a specific type of competition (wielding power) in stereotypically masculine vs. feminine ways. Historically known as an age-related condition that affects older men, the social media posts included in the study repeatedly rebranded low testosterone as a problem affecting younger men, particularly those engaged in fitness and body optimisation. The study shows how these narratives closely mirror those promoted within the manosphere, where hormone levels are presented as a measure of manhood and testosterone is positioned as a way for men to reclaim power, status and control. Young men are being encouraged to undergo testosterone testing and start hormone therapy through Instagram and TikTok content that promotes unproven health claims while downplaying medical risks, a new international study has found.
