What is Testosterone?
Testosterone is a key male sex hormone primarily produced in the testes. It performs several critical roles in the body, including regulating bone density and strength, distributing body fat, maintaining libido, and supporting red blood cell production. Its multiple functions highlight how vital testosterone is for overall health.
Role of Testosterone in Men
In men, testosterone is essential for:
-
Development and growth of the reproductive system
-
Deepening of the voice during puberty
-
Facial, chest, underarm, and pubic hair growth, as well as hair on arms and legs
-
Sperm production
-
Fat metabolism
-
Mood regulation
A small portion of testosterone is converted into estradiol, a type of estrogen that aids sperm maturation and maintains sexual health. Testosterone levels rise during puberty, peak in late adolescence, and gradually decline after the age of 30.
Role of Testosterone in Women
Though present in smaller amounts, testosterone in women plays an important role in:
-
Regulating menstruation
-
Supporting fertility
-
Maintaining sexual function
Low Testosterone in Men
Insufficient testosterone can lead to:
-
Reduced muscle mass and strength
-
Lower bone density, increasing fracture risk
-
Hair thinning or loss
-
Increased body fat
-
Reduced libido and erectile issues
-
Infertility and low sperm count
-
Enlarged breasts (gynecomastia)
-
Difficulty concentrating and depression
High Testosterone in Men
Excess testosterone may cause:
-
Increased risk of heart and cardiovascular problems
-
Enlarged prostate causing urination difficulties
-
Liver damage
-
High blood pressure and elevated cholesterol
-
Acne and oily skin
-
Fluid retention leading to swollen legs and feet
-
Weight gain from increased appetite
-
Blood clot risks
-
Mood swings, headaches, and irritability
-
Increased muscle mass
Both low and high testosterone levels show the importance of maintaining a healthy hormonal balance.
How to Maintain Healthy Testosterone Levels
Doctors may recommend hormone therapy, medications, lifestyle changes, or exercise programs to regulate testosterone. Maintaining a proper diet, regular physical activity, and periodic testing can help ensure levels stay within the optimal range.
If you notice symptoms of low or high testosterone, it is important to get your testosterone levels checked for proper diagnosis and treatment.
