No-scalpel vasal sperm aspiration and in vitro fertilization for the treatment of anejaculation.
OBJECTIVE
To evaluate the utility of no-scalpel vasal sperm aspiration and in vitro fertilization for the treatment of male infertility due to anejaculation.


METHODS
Vasal aspiration was performed using a no-scalpel technique, and the sperm were used for conventional in vitro fertilization in 1 patient and intracytoplasmic sperm injection in 6 patients.


RESULTS
The average total sperm count was 6 x 10(6), with the motility between 20% and 95%. No complications have been observed to date. A high fertilization rate (74.6%) and pregnancy rate (5 of 7) was achieved with subsequent intracytoplasmic sperm injection or in vitro fertilization.


CONCLUSIONS
No-scalpel vasal sperm aspiration is a simple, effective alternative to sperm retrieval, especially for anejaculatory males.
