Abstract
There is no doubt that presence of varicocele contributes to testicular atrophy and decreased fertility in men [1]. There is also evidence that varicocelectomy improved quality of sperm and improve chances of pregnancy although some randomized controlled study were less impressive [2]. Obviously not every man with a significant varicocele has fertility issues or will benefit from varicocelectomy, but the odds favours performing surgery in these patients. It is still unclear through which mechanism varicocelectomy improves fertility. The possible options include decrease in hydrostatic pressure and venous reflex to the testis. There are also data indicating normalization of the testicular temperature and reduction in venous volume stabilize intratesticular testosterone metabolism (testicular proteins exhibit a reduced thermal stability) and improve spermatogenesis [3]. The present study of Bryniarski et al. [4] showed significant benefit of varicocelectomy for testicular growth with the initial hypotrophic testis using laparoscopic approach and confirming previous results in literature. The main advantage of this technique is optical magnification allowing preservation of lymphatics and testicular artery. The authors did not reported any complications with this technique, but it has to be remembered that although it is so called “minimal invasive”, it has its own complications and consequences. It increases cost of instrumentation and has infrequent but more serious complication including injury to the bowel or other organs, peritonitis or air embolism [5]. For that reason, microsurgical subinguinal technique which combines optical magnification for better exposure with easy and simple access, gains popularity [6]. It is also associated with less postoperative pain. It is still difficult to directly correlate improvement in testicular size to the improved sperm function or pregnancy rate. The present study would be more interesting if sperm quality and hormonal status was correlated to the grade of varicocele and tested after varicocelectomy. Indirectly, there were reports in literature, indicating that the sperm quality is inferior in a lot of patients with hypotrophic testis and with higher grade of varicocele. This improves after varicocelectomy [7]. The pregnancy rate increases only up to 50% after varicocelectomy, indicating that even with improved testicular size and/or sperm quality the pregnancy rate are far from optimal. It should be taken into consideration however that there are other factors influencing pregnancy rate equally on men and women site. There is also a question of possible beneficial effect of varicocelectomy on preventing development of late onset of hypogonadal state [8]. Confirmation of that statement obviously will require lengthy longitudinal population study. Varicocelectomy has its place in management of infertile men; however more studies are still required to fine tune evaluation, indication and technique of this intervention.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
