A varicocele means that the veins draining the testes become dilated and incompetent. It similar to varicose veins which affect the legs but this affects the testes.
Varicoceles affect fertility by several mechanisms including elevation of the scrotal temperature and increased sperm DNA fragmentation.
Varicocele repair has been shown to improve semen parameters, improve natural fertility as well as IVF outcomes. Furthermore men who have non obstructive azoospermia (NOA) and a varicocele may start showing sperm in the ejaculate after varicocele repair and those who still have zero sperm count will have a higher chance of finding sperm compared to men with varicoceles that are not repaired.
At CRGH we offer sub-inguinal microsurgical varicocelectomy which is the treatment of choice for varicoceles. It is a minimally invasive surgery which allows identification and division of all the dilated veins while sparing the arteries and lymphatic vessels.
