Many men with varicoceles are able to conceive, but it may impair fertility in some. Varicoceles can be treated with an operation to tie off these dilated veins, in an attempt to improve semen parameters. However, this may not always result in increased conception rates. In NUH, we offer microsurgical varicocelectomy to enable better visualisation of these small abnormal vessels, with higher success rates.
These are the risks associated with the operation:
If the sperm counts are extremely low, or if there is no sperm in the ejaculate due to blocked ejaculatory ducts, there are several techniques that can be used to extract sperm directly from the testis:
The viable sperm that is harvested from any of these approaches can then be used in Assisted Reproductive Technologies (ART) such as in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI), to achieve pregnancy.
These are relatively simple procedures which are usually done under general anaesthesia for your comfort. Potential risks include pain, bleeding, infection, damage to the testis and failure to retrieve viable sperm.
