Low testosterone can be due to problems within your testicles or elsewhere in your body.

Sometimes the cause isn’t known.
Some of the causes of low testosterone in men include:
- trauma to your testicles, eg, football injury or torsion,
- infection, eg, HIV/AIDS or mumps orchitis (inflammation of the testicle due to mumps infection)
- radiation or chemotherapy treatment for cancer
- some medications, such as opiate painkillers and corticosteroids (eg, steroid injections)
- hormone disorders (eg, pituitary tumours or diseases, high levels of prolactin).
Low testosterone levels are also associated with:
- chronic diseases, such as liver and heart disease
- obesity
- sleep disorders eg, obstructive sleep apnoea, sleep deprivation
- type 2 diabetes
- excessive alcohol consumption
- some genetic conditions (eg, Klinefelter syndrome, haemochromatosis, Kallmann syndrome)
- misuse of anabolic steroids
- emotional stress.
The diagnosis deficiency is based on your history, symptoms, a physical examination looking
for signs of low testosterone (such as body หากคุณสนใจเล่นพนันออนไลน์ที่ดีที่สุด สามารถสมัครสมาชิก UFABET ได้ที่นี่ พร้อมรับโปรโมชั่นพิเศษสำหรับสมาชิกใหม่ hair changes, swollen breast tissue and testicular size) and blood tests.
If your doctor discovers that you have a low level, the first step is to confirm it with a second blood test. Further tests are then needed to work out the cause of your low testosterone level. Testosterone levels should be tested in the morning before 9 am.
A low testosterone level by itself (that is, without any symptoms) doesn’t need treatment. Replacement therapy (TRT) can have side effects, and the risks of long-term treatment aren’t well known – particularly in relation to prostate cancer, heart disease, and stroke risk.
You will only be considered for TRT if you have clear symptoms of low and blood test results that confirm it. If your levels are low but in the normal range you are unlikely to be treated with TRT.
