Summary:In men with obstructive azoospermia, bypass surgery would obviously be the most acceptable form of treatment as it gives the couple an opportunity to conceive naturally. However, when this has failed to restore patency or when surgery is not feasible (congenital absence of vas), fertility treatment using spermatozoa aspirated from the epididymis should be considered. Percutaneous epididymal sperm aspiration (PESA) is more acceptable to patients than micro epididymal sperm aspiration (MESA) because it eliminates the requirement for a general anaesthetic, post-operative pain, and the risk of haematoma formation, thus allowing a rapid return to normal activity of the husband. To our knowledge, this is the first reported case in Thailand where a pregnancy resulted in a couple whose infertility was due to azoospermia from the congenital absence of vas deferens. Spermatozoa collected through PESA were used in ICSI to achieve fertilization. The PESA technique, due to its simplicity is the choice of treatment for obstructive azoospermia.
