Yes, a varicocele can directly impact male fertility by affecting sperm quality. This occurs because the dilation of veins in the scrotum raises the temperature of the testicles, impairing their proper function.
Consequently, sperm count may decrease, and sperm motility (the ability to move correctly) and shape may be affected, making it difficult to achieve a pregnancy.
In more advanced cases, if left untreated, a varicocele can even lead to permanent fertility issues. Therefore, early diagnosis and treatment by a specialist—such as Dr. Rodrigo España at Andrología Málaga—are crucial for protecting your reproductive health.
