Testosterone

Hormones

Testosterone plays a crucial role as a sex hormone in both males and females. In males, it originates primarily in the testicles, while in females, it’s produced in smaller quantities in the ovaries.

In males, testosterone is pivotal for the typical development of male sexual characteristics. Throughout puberty, testosterone facilitates the emergence of traits such as body and facial hair, a deeper voice, and enhanced muscle strength. However, an excess of testosterone in males can lead to adverse effects such as testicular shrinkage, impotence, heightened risk of heart ailments, and prostate enlargement resulting in urinary difficulties. Conversely, insufficient testosterone levels can manifest as symptoms like fatigue, irritability, depression, erectile dysfunction, and decreased muscle mass.

In females, in conjunction with estrogen, testosterone contributes to the growth, maintenance, and repair of reproductive tissues and bone density. Excessive levels of testosterone in females may induce acne, increased facial and body hair, irregular menstrual cycles, and mood fluctuations. Conversely, inadequate testosterone levels may lead to diminished libido and weight gain.
