Testosterone replacement therapy (TRT) is a medical treatment for men that restores low testosterone levels to their normal range. Testosterone is a hormone that helps develop male reproductive tissues and maintain secondary sexual characteristics, including muscle bulk, body and facial hair patterns, and bone density.
TRT may be needed when the body does not produce enough testosterone to maintain normal hormonal function. Having a low testosterone reading does not automatically mean that treatment is necessary. Doctors generally consider TRT when testosterone deficiency has been confirmed through appropriate assessment and is associated with relevant symptoms.
The purpose of TRT is therefore to address the underlying testosterone deficiency by replacing the hormone the body is no longer producing in sufficient amounts. This may improve the symptoms that a person is experiencing due to testosterone deficiency.
Testosterone deficiency syndrome, also known as hypogonadism, is a condition characterized by insufficient production of testosterone in men. It can occur due to factors such as ageing or certain medical conditions such as type 2 diabetes, obesity, infections and autoimmune disease.
Testosterone deficiency is relatively common among older men. In Singapore, the Society for Men’s Health estimates that about one in four men aged 45 and above have some degree of testosterone deficiency.
Low testosterone can have several possible causes, including changes with age, underlying health conditions and certain lifestyle or treatment-related factors. These may include:
Testosterone deficiency can affect sexual health, physical function and general well-being. Common signs and symptoms may include:
For men with confirmed testosterone deficiency, TRT may help improve symptoms associated with low testosterone by restoring hormone levels to an appropriate range. Potential benefits of testosterone replacement therapy may include:
The effects of TRT vary between individuals and may depend on factors such as the severity of testosterone deficiency, overall health and lifestyle habits. Maintaining regular exercise, a balanced diet, adequate sleep and other healthy habits can complement treatment and support overall health.
You may want to consider a testosterone test to assess for low testosterone if you:
Do Any of These Apply to You?
If you recognize some of these symptoms or risk factors, a men’s health consultation can help determine whether testosterone testing may be appropriate.
There are several types of testosterone replacement therapy available in Singapore. These include:
Your doctor will advise you on the method that is best suited for your needs, as well as the instructions, dosage and frequency of use.
TRT may have effects and potential risks that vary between individuals. It is often prescribed with ongoing medical supervision by a doctor. Possible side effects and considerations may include:
These risks do not affect everyone, and whether TRT is appropriate depends on your health, testosterone levels and individual risk factors.
A structured clinical approach includes assessing your suitability before treatment and monitoring your response and relevant health markers after TRT has started. This allows the treatment plan to be adjusted when necessary.
At Dr Tan Medical Center, Dr Tan Kok Kuan provides testosterone assessment and replacement therapy as part of his work in men’s health. His approach considers each patient’s circumstances independently, from determining whether TRT is appropriate to selecting a suitable treatment plan and monitoring their response over time.
If you are concerned about low testosterone or would like to understand whether TRT may be suitable for you, book an appointment at our clinic for an assessment.
