Symptoms and causes

What is it?

With andrology, we mean all problems related to the male sex hormone (testosterone). In order to examine these problems, a blood sample is usually taken (early in the morning). Sometimes imaging or sperm analysis is also required to further treat an andrological problem. If necessary, the patient is referred to the urologist.

What problems could arise?


In hypogonadism, there is a shortage of the male hormone (testosterone). The cause may be at the level of the testes (primary hypogonadism or hypergonadotropic hypogonadism) or at the level of the pituitary gland (secondary hypogonadism or hypogonadotropic hypogonadism). The symptoms of hypogonadism are fatigue, increased sweating, reduced muscle strength, decreased libido (desire to have sex), erection problems, symptoms of depression and less body hair.

Treatment of hypogonadism usually involves a testicular exam. Sometimes, an additional ultrasound scan of the testicles or an MRI scan of the pituitary gland is necessary. Depending on the cause, hypogonadism can be treated with medication (taken orally or injected).


Men with gynecomastia have an increased volume of one or both breasts. In gynaecomastia, we make a distinction between increased adipose tissue and increased glandular tissue.

Treating this problem usually requires an ultrasound and/or radiography of the breast. This allow us to check whether there is a malignant tumour in the breast. In addition, a blood sample is needed to determine the male and female hormones.
