Testosterone is a crucial androgen hormone produced primarily in the testes in men and in small amounts by the adrenal glands in both sexes. In women, the ovaries also produce small amounts of testosterone. This hormone plays a significant role in male fertility, influencing sperm production and sexual development, and also contributes to female fertility, though in different ways.
Testosterone's Role in Men
In men, testosterone is vital for spermatogenesis (sperm production) and the development of male characteristics such as muscle mass, voice changes, and libido. Low testosterone levels can lead to fertility issues such as low sperm count, reduced libido, and erectile dysfunction. As men age, testosterone levels naturally decrease, but other factors such as chronic illnesses, testicular damage, or genetic conditions can also contribute to low levels.
Testosterone's Role in Women
Though testosterone is present in much lower amounts in women, it still plays an important role in reproductive health. In women, testosterone acts as a precursor to estradiol, the primary female sex hormone. It also affects bone metabolism, sexual desire, and cognitive function. Abnormally high levels of testosterone in women, such as in cases of polycystic ovary syndrome (PCOS), can negatively affect fertility by disrupting follicle development.
Testosterone Levels and Fertility
Normal testosterone levels are essential for healthy reproductive function. In men, normal levels range between 300-1000 ng/dL, while in women, the range is between 30-70 ng/dL. Decreased testosterone can result in fertility issues, and its restoration, when necessary, can be achieved through various methods like gels, injections, or patches under medical supervision.
Testosterone and IVF Treatment
In assisted reproductive treatments such as IVF, testosterone may be used to enhance ovarian response in women with low ovarian reserve. By improving follicular response, testosterone may lead to better IVF outcomes, although more research is needed to confirm this approach's effectiveness. It is important that the use of testosterone during fertility treatment be closely monitored by specialists.
