Surgical Sperm Recovery is a microsurgery to collect sperms from the male partner in case of very poor sperm count or no sperms in the sample. This is usually performed as a day care procedure on the same day as the egg recovery.
TESE/ MESA/ PESA
They are different sperm retrieval procedures, tailored to the specific couple’s need. The procedure involves the use of minimal invasive techniques to obtain sperms when sperm is not present in ejaculate. This procedure is suitable in case of:
- Azoospermic man; Obstructive azoospermia or Non obstructive azoospermia (when sperm production is low)
- Vasectomised man, where vasectomy reversal is failed.
- Absence of vas deferens
Percutaneous Epididymal Sperm Aspiration (PESA) uses a needle to penetrate the scrotal skin and draw a small amount of sperm from the epididymis where as Percutaneous Testicular Biopsy removes small cores of testes tissue.
The procedures are either performed through the skin (percutaneous) or through a small opening in the skin about 1/2 inch in size. In Testicular Sperm Extraction (TESE) small samples of testis tissue is removed for processing and eventual extraction of sperm. In Microscopic Epididymal Sperm Aspiration (MESA) process, microsurgical techniques are applied to gather sperm from epididymis – a sperm rich tube at the back of the testis. Microscopic TESE is a very exacting search for sperm under high magnification in cases of extremely low sperm production.
