What does testosterone do, and how do you increase low testosterone?

Therefore, understanding the dynamics of testosterone in females, particularly in response to physical activity, is essential for designing effective, sex-specific exercise interventions. In adult men, low testosterone may lead foods to help with low testosterone (macromicro.it) a reduction in muscle bulk, loss of body hair and a wrinkled ‘parchment-like’ appearance of the skin. Current research suggests that this effect occurs in only a minority (about 2%) of ageing men. However, there is a lot of research currently in progress to find out more about the effects of testosterone in older men and also whether the use of testosterone replacement therapy would have any benefits. While many scientific studies and huge amounts of data show the safety of supplemental testosterone in postmenopausal women, only about 50% of women who take it experience a significant increase in sex drive.

The existence and direction of the behavioural differences may be due to ‘deep-seated, biological factors’, but culture heavily influences how those differences play out. That’s why the question of whether male promiscuity, risk-taking and competitiveness were sexually selected adaptations for reproductive success simply doesn’t have the implications for now and the future that we usually assume they do. Nor does it necessarily mean that a hormonal endowment prefigures the male brain for these traits (although that’s not to deny the likelihood of sex-differentiated initial ‘tilts’). So, while a gendered culture influences how these traditional roles play out, I don’t see the evidence that it imposes them.

The fact that Carole and I agree on these things isn’t surprising. I appreciate that contemporary evolutionary biologists recognise the diversity of mating systems, and don’t think of sex as an essence that underpins a ‘natural law’ across the animal kingdom of coy females and competitive males. My objection is with the T-Rex view, in which essentialist thinking creeps in via the back door. And then there are what we might call the ‘sex-reversed’ species, which Charles Darwin discussed in The Descent of Man and Selection in Relation to Sex (1871).

And just as happens for men, women’s testosterone levels drop as they age. Testosterone levels in the blood are controlled by the hypothalamus and pituitary gland. The hypothalamus produces a hormone called gonadotropin-releasing hormone which tells the pituitary gland to release a hormone called luteinizing hormone (LH). When LH reaches the testis, it causes the production of testosterone. Speaking with a healthcare provider before changing your lifestyle or beginning any medical treatment for low testosterone levels is essential. Hormone replacement therapy can have potential risks and side effects, and it is essential to monitor testosterone levels regularly to ensure safety and effectiveness.

Testosterone levels can be influenced by various factors, including age, genetics, lifestyle, and overall health. Certain medical conditions, such as hypogonadism, can also lead to low testosterone levels. On the other hand, factors like regular exercise, healthy diet, and adequate sleep may positively impact testosterone levels. This decline can lead to changes in sexual function, mood, energy levels, and body composition. However, it’s important to note that these changes can also be influenced by other factors, such as lifestyle and overall health.

You acknowledge that sex is an important variable for understanding mating, and you don’t endorse radical sex-neutral theories. But then you take T-Rex (and me along with him) head-first into straw-man territory. This is where maleness is described as ‘a sort of “essence” that determines … predispositions of the male sex role.’ What serious biologist thinks this? My view is that the sexes are born (on average, as always) with different predispositions, leading to what are called ‘traditional sex roles’, which T-Rex gets right. This pattern, of females being more nurturing and males being more competitive, applies to our own species. We do agree on some things – such as the value of reproductive autonomy, a world free of the threat of male violence, and flexibility of gender expression.

In female adults, high levels of testosterone may be a sign of polycystic ovary syndrome (PCOS). This condition is very common — up to 15% of females of reproductive age have it. There’s a wide range of normal or healthy levels of testosterone circulating in the bloodstream.

This hormonal disparity plays a key role in the distinct physiological characteristics observed between the sexes, particularly in terms of muscle mass, strength, and metabolic functions46. Adequate testosterone levels are essential for optimizing physical performance and muscle strength, regardless of sex12. Testosterone is pivotal in protein synthesis, facilitating muscle growth and repair processes.

A nutritionist provided dietary guidance to ensure participants followed these recommendations for 48 h before each session, minimizing potential nutritional influences on the study’s primary outcomes. Furthermore, participants had a standardized breakfast before each session, regardless of their menstrual cycle phase, and all blood samples were taken within 15 min after the protocol to avoid hormonal surges throughout the day. In females, testosterone is needed for bone and muscle strength and sex drive. “The standard of care for prostate cancer is androgen deprivation—or ‘chemical castration’—in which you reduce testosterone levels almost to zero,” says Dr. Reina-Campos.
