Dm. Nudell et al., THE MINI-MICRO-EPIDIDYMAL SPERM ASPIRATION FOR SPERM RETRIEVAL - A STUDY OF UROLOGICAL OUTCOMES, Human reproduction, 13(5), 1998, pp. 1260-1265
Epididymal sperm aspiration and in-vitro fertilization (IVF) with intr
acytoplasmic sperm injection is an established treatment for obstructi
ve azoospermia. Sperm aspiration is performed with either an incision
or percutaneously, To control costs, minimize morbidity and retain the
advantages of both approaches, we developed a mini-incision technique
for epididymal aspiration and here report sperm retrieval and procedu
re-related outcomes. Twenty-six consecutive patients with obstructive
azoospermia underwent epididymal sperm retrieval through a 1 cm incisi
on with local anaesthesia to provide spermatozoa for concurrent IVF cy
cles. The quality of retrieved spermatozoa, the quantity of spermatozo
a cryopreserved as well as anaesthetic requirement, recovery time and
patient satisfaction were evaluated. Fresh epididymal spermatozoa were
retrieved in 25 of 26 (96%) patients. In one patient, testicular sper
m extraction was necessary. Excess motile spermatozoa were cryopreserv
ed in 24 of 26 (92%) patients; a mean total motile count of 4.8 x 10(6
) motile spermatozoa were banked. The procedure was performed with 62%
of patients receiving minimal i.v. sedation. Post-procedure recovery
was rapid, with a median time to return to work of 2.0 days with a med
ian of 2.0 pain pills taken. Procedure-related satisfaction was high.
The mini-micro-epididymal sperm aspiration achieves the goals of relia
ble retrieval of abundant epididymal spermatozoa with a single, minima
lly morbid procedure. It appears to combine the advantages of the inci
sion and percutaneous approaches.
