Masculine infertility


Around 50% of couples cannot achieve a pregnancy after a year of sexual relations without contraceptive methods.

Change in life habits and the decision of having children at a more advanced age result in seminal alterations that make achieving a pregnancy more difficult.

Masculine infertility may be due to several causes. Some of them can be identified and reversible. Some others can be identified but do not have a solution. Aetiology is not possible for many patients, which means there are idiopathic causes.


An andrologist can identify the causes of masculine infertility through an evaluation consisting of a clinical examination and some diagnostic tests, such as spermiogram, used to make an in depth-study on the patient’s reproductive capability. It can also be complemented with hormonal evaluation, testicular ultrasound, karyotype blood and other specific tests depending on the clinical suspicions.

Once the infertility cause has been detected, the andrologist may suggest a specific treatment to increase the patient’s fertility with a view to achieving pregnancy with sexual relations.

If there is not any treatment available for the patient, he can avoid the stress and frustration that useless options would trigger. The evaluation can also detect genetic causes for infertility that the patient himself or his progeny may suffer.

In cases where there are not available treatments, assisted reproduction may still be considered. We can recur to the collection of testicular or epididymal sperm to perform an intracytoplasmic sperm injection (ICSI).

Our aim is to identify the causes of infertility. In case there is not a solution to it, we try to provide a better fertilization ability.

Is the end of vasectomy coming?

Recently, there has been a relentless colloquium related to new contraceptive techniques for men in round-table discussions celebrated in Korea.

Other ways, such as hormonal treatments, […]
