MESA, Microscopic Epididymal Sperm Extraction
At Innovative Fertility Center, we consider MESA (microsurgical epididymal sperm aspiration) to be the best way to obtain sperm in men that have a blockage in the delivery of the sperm into the ejaculate. In these cases, sperm is still being produced in adequate amounts, but cannot move from the epididymis to the testicle and into the ejaculate.
Causes of no sperm in ejaculate:
- unsuccessful vasectomy reversals
- cystic fibrosis
- trauma to the testicular area
With MESA, a urologist, using a specialized microscope, removes the sperm directly from the epididymal tubes. First, the urologist or surgeon will make a small incision in the scrotum. The surgeon then identifies the epididymal tubes and aspirates the fluid, which typically results in a high number of motile sperm to be used immediately or frozen for future IVF cycles.
Cryopreserved (frozen) sperm samples will eliminate the need for future sperm retrieval procedures and decrease the damage to the epididymis.
The MESA procedure requires general or spinal anesthesia. Your urologist will discuss recovery time and restrictions involved for patients undergoing a MESA procedure.
