Male Infertility::
Percutaneous Epididymal Sperm Aspiration (PESA):
This is the procedure used to aspirate sperm from the
collection system of the testis (epididymis) in men with obstruction
in the vas deferens (the tube that transports sperm to the seminal
vesicles) from where it is ejaculated. This procedure requires
either local, sedation, or short general anaesthesia. The sperm
collected can then be used for Intra Cytoplasmic Sperm Injected (ICSI), whereby a single sperm is injected directly into an egg, on the same day, and/or frozen for later use.
