Testosterone Therapy: What Men Need to Know About Low T and TRT Treatment Los Angeles Times
I see unambiguous evidence that it can account for some of the large and extremely impactful differences between men and women, particularly when it comes to sexual psychology and aggression. Its starting point is what the anthropologist Sarah Blaffer Hrdy has called the ‘coy female’ paradigm – the idea that asymmetries in what it costs females versus males to have babies make males more motivated by mating success. Males potentially invest as little as a sperm, while females contribute a nice plump egg and, in mammals, full bed-and-board in utero and lactation. Over evolutionary time, this means males will develop traits that help them fight for access to females, and appear more appealing to females browsing for their next mate. This case study belongs to a robust body of evidence that makes me sceptical of the significance of testosterone.
Yes, TRT has been said to lower sperm count, especially if taken without precautions. That is one reason why some men are prescribed hCG (human chorionic gonadotropin) alongside TRT to maintain testicular function and fertility potential. Let’s look at the main functions of testosterone and get an overview of what testosterone imbalances can look like.
Hormonal balance, including optimal testosterone levels, is pivotal in preserving overall health and well-being across various physiological systems. Testosterone, predominantly recognized as a male sex hormone, is also present in females, albeit in smaller quantities, exerting multifaceted effects on both genders6. In males, testosterone is integral to the development of secondary sexual characteristics, such as facial hair growth and deepening of the voice, as well as supporting reproductive function. Moreover, testosterone influences mood regulation, cognitive function, and bone density, contributing to psychological and skeletal health7,8. In females, while estrogen and progesterone are primary sex hormones, testosterone contributes to libido, energy levels, and overall vitality9.
A man’s testosterone levels will typically peak somewhere between age 20 and 30. After this time, they will gradually decrease for the rest of his life. Testosterone levels are estimated to decrease by 1 percent annually after age 30 to 40.
But even in nonhuman animals, testosterone is just one variable in a complex system, one of many factors that feeds into an animal’s decision-making. Social context and experience can override T’s influence on behaviour, or even stand in for T’s absence. Moreover, T responds to contexts and situations, helping us adapt to them. This means that how much T a body has, and how it reacts to it, are inextricably intertwined with the individual’s history and experience – including, in our own case, the influence of gender norms. Generally, total testosterone levels below 300 ng/dL (nanograms per deciliter) may indicate low T, but it’s nuanced.
LJI Assistant Professor Miguel Reina-Campos, Ph.D., specializes in using spatial transcriptomics tools to advance the field of tissue immunology. Spatial transcriptomics gives scientists a way to track where immune cells are located (the "spatial" part) and exactly how those immune cells are trying to protect the body (the "transcriptomics" part). In this dialogue, Carole has denied that she thinks that testosterone ‘makes men what they are’. Yet in her recent TED talk, she stated that prenatal testosterone ‘made my son who he is today’. Testosterone’s impacts are not pre-programmed by evolution but guided by the meanings humans attach to behaviours, dynamically tuning behaviour within a cultural framework.
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 is a hormone found in humans, as well as in other animals. Women’s ovaries also make testosterone, though in much smaller amounts. Men and women need the proper amount of testosterone to develop and function normally. Formal informed consent was obtained from all individual participants included in the study. All the individuals who participated in this study were adults, and they willingly participated in this study. They were assured that their information would be kept anonymous and that the obtained results would only be used for the research.

Testosterone is one of over sixty chemical messengers (hormones) in the body that regulate all our critical functions. Hormones such as testosterone enter the bloodstream and seek out their receptor cells for binding to engage their actions. While testosterone plays a role in sperm production, supplementing with testosterone actually decreases sperm production and can impact fertility, Dr. Patel says. So, it’s important to talk to your doctor before using testosterone therapies. Testosterone plays a role in bone density and maintaining bone mass effect 3 health boost wikia - https://mcmia.org/,.
They compete intensely for control of beaches where females come to give birth and mate. To establish dominance, they will bite and ram each other with their huge bodies, which can weigh up to 4 tonnes (around four times the average weight of females). The battles can go on for hours, but successful dominant bulls, identifiable by the cuts and scars on their chests, will mate with dozens of females who will bear their pups.
