Male partners will be asked to provide fresh sperm at about the same time their partner’s eggs are collected. The healthiest sperm are selected following a special process that is carried out in the laboratory.
In certain cases, surgical sperm retrieval is recommended. These include a low sperm count, testicular tubal blockage/damage/absentee. Surgical sperm retrieval is done through PESA and TeSA techniques and done under local anaesthesia
- PESA (percutaneous epididymal sperm aspiration) – sperm are collected from the epididymis using a fine needle
- TeSE (testicular sperm extraction) – a biopsy is taken from the testicular tissue in order to remove some sperm.
