MESA is a microsurgical epididymal sperm aspiration.
The procedure for aspiration of sperm is usually carried out by a specialist (urologist) who specializes in male fertility issues. In some cases, she may have a reproductive endocrinologist, i.e. a doctor who specializes in the treatment of infertility.
If the sperm gets the same day, then the egg, it can be used immediately. If not, it can be frozen and used later. However, before you expect it, you must defrost it. Usually, spermatozoa obtained by the aspiration method are absent during numerous IVF attempts.
Spermatozoa released from the seminiferous tubules during the MESA procedure are usually less mature and motile compared to the spermatozoa that are found in the ejaculate.
