Testosterone is a vital male sex hormone that plays a key role in reproductive and sexual function. Testosterone is an androgen, meaning it stimulates the development and maintenance of male characteristics. This hormone has wide-ranging impacts on a man's physical and emotional health throughout his life.
Some key functions of testosterone include:
- Promoting muscle growth and strength
- Regulating sex drive and erectile function
- Stimulating sperm production
- Contributing to bone density and strength
- Influencing fat distribution and metabolism
- Impacting mood, focus, motivation, and energy levels
Testosterone is naturally produced by the testes and the adrenal glands. Production peaks during adolescence and early adulthood when levels of this hormone drive growth and changes associated with puberty, such as increased body hair, muscular development, and deepening of the voice.
As men age, their bodies gradually make less testosterone. Signs this natural decline may include low energy, changes in body composition, low sex drive, and erectile dysfunction. However, testing is required to determine if
low testosterone is causing symptoms.
If a test confirms clinically low testosterone, also called hypogonadism,
testosterone replacement therapy may be an effective treatment option. When appropriately prescribed and monitored by a physician, research shows testosterone supplementation can help restore normal hormone ranges and alleviate associated effects on mood, energy, sexual function, and body composition.
There are several delivery methods for testosterone replacement therapy, including injections, transdermal gels and patches, pellets placed under the skin, and other options still being developed and tested. Each approach has pros and cons to weigh with your healthcare provider to choose the optimal testosterone treatment based on your health profile, lifestyle, preferences, and goals for therapy.
Monitoring health via regular bloodwork is important for all men, especially as testosterone naturally wanes later in life. Detecting and addressing a possible testosterone deficiency sooner rather than later can help alleviate frustrating symptoms and improve one's overall well-being.
