A condition manifested by abnormal dilation of the veins of the spermatic cord, caused by incompetent valves in the internal spermatic vein and resulting in impaired drainage of blood into the spermatic cord veins when the person assumes an upright position. This can also cause an increase of the temperature of the local area, which can further damage the sperm.


Varicocele is the most common cause affecting the number, mobility and morphology of the sperm (oligo-astheno-teratozoospermia). It most commonly occurs on the left side of the male patient and is classified as Asymptomatic, thus preliminary examination of adolescent males, is important.


Its treatment is exclusively surgical. During the surgery, all the defective veins of the testicle (varices) are dissected and ligated, without affecting any arteries and lymph vessels in the area.


By applying the microsurgical technique we can avoid the side effects of the older methods, such as ‘Palomo’ and ‘Ivanisevitsh’, which are still widely applied and may lead to a new operation, due to post-operational implications. With the microsurgical technique, the results of the operation present 65-70% improvement of the sperm and 40-45% pregnancy.
