Answer from: Raúl Olivares, MD
TESA can take up to 15 minutes or 45 minutes. This will depend on the structure of the testicles and how easy it is for the lab to identify sperm. In general, what we usually do is take a sample of the testicle or an aspiration depending on whether we are doing a TESA or a TESE, and we send that sample to the lab. If the lab identifies a sperm, and they consider that the amount is enough to carry out the treatment, we finish the process. If not, we just keep taking parts of the testicle and small portions of the testicle until we either decide that it’s very unlikely to get any sperm or the lab considers that we have enough sperm to carry out the treatment.
As I’ve said, depending on each case, it could be really fast, for example, in cases of vasectomies in which there is usually a lot of sperm in the testicle, or it can take really long in cases of real secretory azoospermia with small testicles where it could be really hard or sometimes even impossible to get sperm.
What is the timeframe for TESA procedure for patient?
Does TESA procedure take a long time to perform? What is the recovery time? How does it work?
