The male hormone testosterone plays an important role in our health and wellbeing. The levels of testosterone in the body can be affected by many factors, which can sometimes lead to a deficiency of this essential hormone.
 
Testosterone Deficiency
 
Puberty
Testosterone levels rise during adolescence. It is the presence of testosterone that causes the male genitalia to mature. This hormone also stimulates the development of other masculine features, such as the growth of facial and body hair. A lack of testosterone at this age due to a medical or genetic condition such as Klinefelter’s syndrome could prevent the body from developing normally. Early testosterone deficiency treatment may be able to help.
 
Adulthood and Middle Age
The levels of testosterone in the body remain high in early adulthood, but they can begin to drop once we pass the age of 30 as part of the natural ageing process. The decline is usually slow, so it is rare to experience any symptoms before you are in your 40s or 50s. However, the decline can be faster if you are overweight, you have other health problems or unhealthy lifestyle habits, or if you are just unlucky.
A lack of testosterone can have a negative impact on your sex drive, sexual function, mood, and physical health. Your doctor will be able to check the hormone levels in your blood and prescribe testosterone deficiency treatment if necessary.
 
Other Causes of Testosterone Deficiency
Although the ageing process is the most common cause of low testosterone, there are other issues that can affect your hormone levels:
 
1. Some genetic disorders and medical conditions can affect hormone production.
 
2. Injuries, surgery or infections involving the testes can prevent them from producing enough testosterone.
 
3. Injuries or illnesses affecting the pituitary gland can also reduce testosterone production, because the pituitary controls hormone production by the testes.
 
4. Alcohol, drugs and smoking can also adversely affect testicular function in later life.
 
If you have low testosterone levels for any reason, it may be possible to restore them to normal with testosterone deficiency treatment. Replacing the lacking hormone should help to ease your symptoms, although any underlying cause of the deficiency should be identified and treated too.
