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.

Research shows that men with higher ratios of total testosterone have a reduced incidence of Alzheimer’s disease. There’s also evidence for a strong correlation between testosterone and thinking abilities such as verbal memory and faster processing speed. Testosterone treatment for men 34 to 70 years old has shown an improvement in spatial memory. Deciding to pursue a course of TRT involves deciding between the perceived benefit of the therapy on the symptoms of a particular individual and the risks of the treatment.

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.

The discussion of the key results is appended below under different subsections. It acts on the male body and brain during critical developmental periods – in utero, around birth, and during puberty – with effects on behaviour that often show up down the road. Boys tend to play more roughly than girls, even though young children’s testosterone levels don’t differ very much. Scientists believe that higher testosterone in fetal males drives this preference, as it does in other mammals. Violent crime, which is overwhelmingly committed by men, doesn’t peak when will saw palmetto lower testosterone peaks in the late teens; instead, it peaks in men’s 20s, the phase of life when size, strength and competition for mates are at their highest. The existence of the paternal California mouse, as well as emotionally sensitive, high-testosterone human roughnecks, is entirely compatible with the hormone driving sex differences in aggression.

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).

Life expectancy has increased, and many men now live beyond the age of 60 years. Testosterone is the hormone responsible for the development of male sexual characteristics. Hormones are chemical messengers that trigger necessary changes in the body.
