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
O. Hovatta et al., 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, Human reproduction, 8(10), 1993, pp. 1692-1695
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.
