Objectives: In 2008, Gat et al. wrote the hypothesis that benign prostatic hypertrophy (BPH) was caused by reflux from high free testosterone containing blood from varicocele. The purpose of this study is to measure testosterone at the prostatic veins in patients operated for large BPH, confirming Gat's theory.
Material And Methods: In 13 patients, operated by Millin technique, the periprostatic plexus was punctured in 45° tilted position in order to the measure total and free testosterone and dihydrotestosterone. Brachial blood was taken simultaneously for similar measurements. Seven patients had a clinical varicocele.
Results: High testosterone levels, in comparison with the brachial blood, were detected in only two patients. Dihydrotestosterone was at least doubled in all cases, demonstrating that the puncture was done in prostatic drainage area.
Conclusion: Gat's theory, concerning the role of varicocele in the origin of BPH, could not be confirmed in this study. Technical limitations can be responsible for this.

Background: Surgical repair can be offered to patients with scrotal pain of suspected varicocele origin. The estimated success rate of pain resolution is approximately 80%, although recent publications have been inconsistent. Predictive variables for successful outcomes remain contested.

Purpose: To describe the varicocelectomy model using bull testicles and to evaluate microsurgical practice using the surgical microscope and video magnification system.
Methods: Bovine testicles and spermatic cords were used, with the medial portion of the cord left free for the microsurgical varicocelectomy technique. Twenty 3rd-year medical students were divided into two groups, the video magnification system group (VSMG) and the surgical microscope group (SMG), to simulate varicocelectomy in the proposed model.

Nutcracker syndrome (NCS) is a relatively uncommon vascular condition characterized by compression of the left renal vein (LRV), resulting in a variable spectrum of nonspecific symptoms, including hematuria, flank pain, varicocele, and pelvic congestion syndrome. NCS can be classified into anterior and posterior types regarding the origin of LRV compression: anterior NCS occurs when LRV is compressed between the aorta and superior mesenteric artery, whereas posterior NCS involves LRV compression between the aorta and the spine. Despite advancements in diagnostic modalities, including Doppler ultrasound, computed tomography, magnetic resonance imaging, and invasive techniques like phlebography, there is still no globally accepted diagnostic algorithm, leading to inconsistencies in diagnosis.

Infertility affects 15% of couples in developed countries, 50% accounting for male origin. In 2021, sperm DNA fragmentation (SDF) testing was incorporated into male fertility evaluations as an evidence-based functional test. We aimed to assess the effect of interventions that could potentially improve SDF.

Variations of the left renal vein can be in the form of circumaortic vein or renal collar, retro-aortic vein, additional renal vein, or multiple primary tributaries. We report a unique complex venous pattern of concomitant circumaortic and retro-aortic left renal veins associated with a fenestrated left renal artery. Two renal veins, anterior and posterior to the renal artery, originated from the renal hilum.
