Objective: To compare the clinical effects of inguinal varicocelectomy, Palomo varicocelectomy,laparoscopic varicocelectomy, and microscopic varicocelectomy in the treatment of varicocele.
Methods: We retrospectively analyzed the pre- and post-operative clinical data about 318 cases of varicocele,108 treated by inguinal varicocelectomy,84 by Palomo varicocelectomy,68 by laparoscopic varicocelectomy, and 58 by microscopic varicocelectomy. We compared the operation time, hospital stay, pre- and post-operative sperm concentration and progressive motility, incidence of complications, rate of recurrence, and rate of sperm quality improvement among the four groups.
Results: The operation times for the inguinal, Palomo, laparoscopic, and microscopic varicocelectomy procedures were(50. 3 ± 13. 9),(70. 4 ± 14. 3),(35. 1 ± 11. 1),and(65. 3 ± 13. 2) min, respectively, significantly shorter for the laparoscopic strategy than for the other three( P < 0. 05). The lengths of hospital stay of the four groups of patients were(6. 3 ± 1. 6),(5. 7 ± 1. 5),(4. 3 ± 1. 4),and(3. 4 ± 1. 3) d, respectively, remarkably shorter in the microscopic group than in the other three( P < 0. 05). The microscopic group also showed a significantly lower rate of postoperative complications, incidence of spermatic vein reflux, and recurrence( P < 0. 05) and higher rates of improvement in postoperative sperm concentration and progressive motility than the other three groups( P < 0. 05).
Conclusion: Microscopic varicocelectomy is superior to inguinal,Palomo and laparoscopic varicocelectomy procedures in the treatment of varicocele for its lower incidence of complications, higher rate of sperm quality improvement,and shorter length of hospital stay. It is therefore more suitable to be applied in community hospitals.

Purpose: To investigate the effects of varicocelectomy on premature ejaculation (PE) in patients with varicocele and infertility.
Methods: A total of 82 sexually active patients aged 18 years or over who had undergone microscopic subinguinal varicocelectomy with a clinical diagnosis of varicocele in 14 urology clinics between October 2021 and March 2023 with primary infertility were evaluated prospectively Patients were evaluated using the Turkish validated form of the 'Premature Ejaculation Diagnostic Tool' (PEDT) scale. A PEDT score of 11 or above was taken to indicate the presence of PE.
Assessing the outcomes of subinguinal microsurgical varicocelectomy: pulling technique compared to the conventional method.

Introduction: The positive effect of varicocelectomy on sperm parameters (sperm morphology, concentration, motility) and fertility and pregnancy rates has been proven. Although various techniques have been defined for varicocele treatment, varicocelectomy with the pulling technique was first defined in 2017. The aim of this retrospective study is to compare the effectiveness and reliability of subinguinal microsurgical varicocelectomy with the "pulling" technique and conventional subinguinal varicocelectomy.

This condition may disrupt normal neuroregulation, blood supply, and temperature regulation in the testicles, thereby impacting sperm count, quality (morphology, fragmentation rate), and functionality (motility). It may even induce symptoms such as pain and testicular atrophy.

Article Synopsis
- * A study involving 96 patients who underwent microscopic subinguinal varicocelectomy (MSV) found significant increases in testicular arterial blood flow volume (TABFV) post-surgery, particularly for the left testis, which was more than double the preoperative level.
- * Researchers developed a diagnostic model using preoperative TABFV and the presence of subclinical right-sided varicocele to predict semen improvement after MSV, achieving a strong performance with an area under the curve (AUC) of 0.824,

Background & Objectives: Notably, 17-hydroxy progesterone (17-OHP) (17-OHP) is a precursor for testosterone (T) synthesis, and intratesticular testosterone (ITT) is essential for spermatogenesis. Varicocele (Vx) has an estimated prevalence of 15% in the general population and 35% in those with primary infertility. We aimed to evaluate the correlation between changes of serum 17-OHP after sub-inguinal micro-varicocelectomy and improvement of semen parameters.
