Introduction::
Varicocele disease is well-known cause of infertility in men. The presence of spermatic varices veins create a hostile environment to spermatogenesis. It results in reduced quality of the sperm production and in some cases can determine a total absence of sperm. The varicocelectomy procedure in patients with non-obstructive azoospermia (NOA) can raise the rates of sperm in the semen analysis. A positive rate for sperm, even if very low, may be sufficient to enable the capture of sperm intended for in-vitro fertilization without the use of donor sperm.
Objetive::
To evaluate the raise of sperm in NOA patients with varicocele disease who were submitted to a bilateral procedure to recovery sperm production.
Method::
We analized the sperm results of 25 NOA patients who undergone to a bilateral varicocelectomy procedure.
Results::
From a total of 25 patients, three (12%) recovered sperm count four months after procedure. One year after the procedure, five (20%) patients recovered sperm production.
Conclusion::
Patients with varicocele disease and azoospermia, without genetic changes or obstruction of the spermatic tract, should undergo surgical procedure to recover sperm.
