Abstract
This study was conducted to assess the outcomes of TESA in women undergoing oocyte donation. Descriptive reports from a university IVF practice were reviewed to evaluate the outcomes of women (n = 10) who underwent 12 cycles of ovum donation and required testicular sperm aspiration due to obstructive azoospermia (n = 6) and nonobstructive azoospermia (n = 4). Percutaneous needle aspiration of the testes was performed prior to oocyte retrieval to recover sperm, and intracytoplasmic sperm injection was subsequently performed on the donated oocytes. Fertilization was documented 16-18 h later and transcervical embryo transfer performed 72 h postretrieval. Successful retrieval of testicular spermatozoa utilizing the percutaneous technique was achieved in all 12 cycles. All cycles resulted in an ET with the achievement of 7 (58%) pregnancies, of which 5 (42%) are ongoing or delivered. The individual embryo implantation rate was 18.4% (9/49). Two cycles (16.6%) produced supernumerary embryos for cryopreservation. TESA represents a simple procurement technique associated with minimal morbidity. It may be offered even in cases of nondestructive azoospermia.
