Male Hormone Conditions
A lack of testosterone can be found during investigation into a lack of libido, general lack of energy, or fertility problems. More recently low testosterone levels have been associated with Type 2 diabetes.
The lack of testosterone may be primary- that is caused by testicular problems, or secondary- say to pituitary disease or genetic problems.
Testosterone replacement may be appropriate depending on the circumstances and the assessment of the problem.
To investigate these problems, blood tests are performed to determine both the pituitary hormone production of stimulating hormones as well as the testosterone level. Further investigations may require scans of the pituitary, an ultrasound of the testis, or genetic assessment.
If treatment is required this is commonly offered as either gels to be applied to the skin or injections to be administered intermittently. There are other forms of administration which are used less frequently. Your doctor will discuss with you the pros and cons of the various methods of administration
During treatment with testosterone it is necessary to monitor the blood count, the prostate and the liver as all of these can become upset during long term treatment.
