EPIDIDYMAL SPERM ASPIRATION AND USE OF DONOR SPERMATOZOA WHEN NECESSARY FOR IN-VITRO FERTILIZATION, AND VASOEPIDIDYMOSTOMY - AN ACCEPTABLE COMBINATION IN THE TREATMENT OF OBSTRUCTIVE AZOOSPERMIA

Infertility due to obstructive azoospermia in 24 men was treated with a combination of scrotal exploration, microsurgical sperm aspiration a nd vasoepididymostomy, at the same operation. In-vitro fertilization ( IVF) and embryo transfer were performed using epididymal spermatozoa. Donor spermatozoa were used if no motile epididymal spermatozoa were o btained. With this combination, emotionally and economically acceptabl e pregnancy rates were achieved: 24% per aspiration, 43% per embryo tr ansfer, and 25% per couple. One twin pregnancy resulting in the birth of two healthy female infants and one ongoing twin pregnancy were achi eved with epididymal spermatozoa; four pregnancies (one twin, two sing letons, one abortion) were achieved with donor spermatozoa.
