Efficacy of varicocelectomy in primary infertile patients with isolated teratozoospermia. A retrospective analysis

The present study assessed the results of varicocelectomy in patients with isolated teratozoospermia. Sixty-two infertile men with isolated teratozoospermia were evaluated retrospectively. There were significant improvements between preoperative and postoperative mean percentages of spermatozoa with normal morphology (1.15 +/- 1.1% versus 2.3 +/- 1.8%, p < .001) and spermatozoa with head abnormalities (92.9 +/- 4.5% versus 88.6 +/- 7.4%, p < .001). Nineteen (31%) patients had children through natural conception, 4 (6%) patients had children with assisted reproductive techniques and 39 (63%) patients had got no children within a mean follow-up period of 31.3 months. In patients who had children with natural conception, significant improvements were detected in postoperative mean percentages of spermatozoa with normal morphology (p < .001), head abnormalities (p < .001), neck/midpiece abnormalities (p = .003) and tail abnormalities (p = .007). When semen parameters of men who had children via natural conception was compared with the men with no children, we found that the percentage of spermatozoa with normal morphology was significantly higher (p = .008) and percentage of spermaztozoa with head anomalies was significantly lower (p = .019) in men who had children via natural conception. We believe that varicocelectomy is a beneficial surgical method for the treatment of isolated teratozoospermia and better postoperative rates of spermatozoa having normal morphology and head abnormalities are related with natural conception.
