As far as infertility is concerned, males are equally affected by it. Infertility in men is often related to inability to produce sperm in their semen or a low number of motile sperms in ejaculate which are not sufficient to carry out with the IVF process. If the cause of low sperm production is physical rather than genetical like blocked testicles or irreversible vasectomy the micro surgical techniques helps in retrieving the sperms.
All the three techniques PESA, MESA AND TESA are carried out on outpatient surgery centre and doesn’t require any overnight stay. The techniques involve aspiring sperms using needles and tubes placed through the skin under testes under local anesthesia.
PESA stands for epididymal sperm aspiration – A needle and syringe are used to suck the fluid by placing a needle directly into the epididymis through scrotum skin.
MESA stands for microsurgical epididymal sperm aspiration – It’s an open surgical sperm retrieval procedure which involves microscopy to locate the tubules of the epididymis in order to extract a large number of sperms.
TESA stands for testicular sperm aspiration – Same needle and syringe technique as in PESA is used to suck the fluid inside testicles through the skin of the scrotum.
The procedure would be carried out usually the day when eggs would be retrieved or a day in advance and you are free to carry on with the routine desk type job in a day or two after the procedure.
