Synopsis: Testosterone level charts for males and females showing average readings of total, bioavailable, and free testosterone. In males, the testes produce testosterone, while the ovaries produce testosterone in females. Additionally, both sexes produce small amounts of testosterone in the adrenal glands.

Introduction

Testosterone, an androgen hormone, is essential for both males and females. While commonly recognized as a primary male sex hormone, females also require certain levels of testosterone. In females, a significant portion of testosterone converts into the sex hormone estradiol.

Main Item

Measuring Testosterone

Males and Testosterone

In males, the testes produce testosterone, while the ovaries produce testosterone in females. Additionally, both sexes produce small amounts of testosterone in the adrenal glands.

Typically, adult males have a testosterone concentration between 265 and 923 nanograms per deciliter in their blood, whereas adult females have considerably lower levels. Testosterone levels can vary widely between individuals and throughout a person's life. Generally, males have substantially higher testosterone levels than females.

Testosterone serves as the primary male sex hormone and anabolic steroid in males. In humans, it plays a crucial role in the development of male reproductive tissues, such as the testes and prostate. Additionally, testosterone promotes secondary sexual characteristics like increased muscle and bone mass and the growth of body hair. It is associated with increased aggression, violence, criminal behavior, sex drive, and courtship behaviors aimed at impressing partners.

Females and Testosterone

In women, testosterone levels are higher before and after intercourse compared to before and after cuddling. Administration of testosterone has a time lag effect on genital arousal in women. Furthermore, a continuous increase in vaginal sexual arousal can result in heightened genital sensations and sexual appetitive behaviors.

When females have a higher baseline level of testosterone, they experience greater increases in sexual arousal levels but smaller increases in testosterone, suggesting a ceiling effect on testosterone levels in females. Sexual thoughts can influence testosterone levels but not cortisol levels in the female body. Additionally, hormonal contraceptives may impact the variation in testosterone response to sexual thoughts.

Health and Well-being

In both sexes, testosterone contributes to overall health and well-being. It significantly affects mood, cognition, social and sexual behavior, metabolism, energy output, the cardiovascular system, and the prevention of osteoporosis. Insufficient testosterone levels in men can lead to abnormalities, including frailty, adipose fat accumulation, anxiety, depression, sexual performance issues, and bone loss.
