Comparison of surgical effect and postoperative patient experience between laparoendoscopic single-site and conventional laparoscopic varicocelectomy: a systematic review and meta-analysis

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.

Evaluation of clinical effects of microsurgical subinguinal varicocelectomy with and without testicular delivery

The aim of this study was to access whether microsurgical subinguinal varicocelectomy (MSV) with testicular delivery has a better therapeutic effect than MSV without testicular delivery, including semen quality, serum testosterone (T) level and International Index of Erectile Function (IIEF)-5 score in infertility male patients with varicocele. In this prospective study, 181 patients were included and they chose the treatment by themselves. A total of 114 patients who received MSV without testicular delivery (TD) and 67 patients who received MSV with TD were followed-up 6 months after the operation. Semen parameters, serum T level and IIEF-5 scores were recorded before and 6 months after the operation. Results showed that MSV with or without TD could improve semen quality, serum T level and IIEF-5 score. For semen quality 6 months after the operation, there was no significant difference between patients received MSV with or without TD. But in patients with varicocele of grade III, MSV without testicular delivery improved the sperm concentration and motility more. And patients received MSV without TD have a higher T level 6 months after the operation, especially in patients ≤27 years. MSV with TD is not superior to that without, but this should be verified in more samples and a better designed randomised controlled study in the future.
