Objective: To review the evolution in indications for treatment and treatment modalities for adolescent varicocele at our centre, and evaluate the impact of varicocelectomy on final outcome.
Patients And Methods: Between 1995 and 2006, we treated 242 left varicoceles. Preoperative assessment included clinical evaluation, measurement of testicular volumes, and colour-Doppler ultrasound (CDUS). A subinguinal varicocelectomy was performed in 124 patients (group A), and a laparoscopic non-artery-sparing Palomo procedure in the remaining 118 (group B). In group B patients, CDUS was also used to investigate the functional anatomy of varicocele, and all the veins found to be refluxing were divided during surgery. The two groups were compared with regard to indications for surgery and outcome.
Results: Over time the proportion of patients operated on because of testicular growth retardation increased. Persistence/recurrence rate was comparable between the two groups. In 13% of group B patients, the deferential vein was found to be refluxing on preoperative CDUS and was divided at surgery. Hydrocele rate was higher in group A, unless the vaginalis was excised and everted during varicocelectomy. About 75% of patients with preoperative left testicular growth failure experienced postoperative catch-up growth, irrespective of treatment.
Conclusion: Indications for treatment are still evolving. Varicocele can successfully be treated in the majority of cases by either a laparoscopic or subinguinal approach. Both techniques require care, and CDUS can aid in the decision making. Most patients with preoperative testicular growth failure experience postoperative catch-up growth.

To identify candidate genes and pathways involved in testicular development in Takifugu rubripes, a comparative transcription analysis was conducted across the various developmental stages of the testis (stages II to V). A total of 9520 differentially expressed genes (DEGs) were identified among the different stages, and they were significantly clustered into six clusters (P < 0.05).

Diquat (DQ) is a pro-oxidant that generates free radicals in cells through redox reactions, leading to the induction of oxidative stress. During the processes of growth and reproduction, poultry are particularly vulnerable to oxidative stress. Selenium yeast (SeY) serves as an organic selenium source characterized by high activity and low toxicity, imparting antioxidant effects.

During avian germ cell formation, primordial germ cells (PGCs) differentiate into prospermatogonia in testicular seminiferous tubules or into oogonia in the ovarian cortex in late-stage embryos. Although estrogenic endocrine-disrupting chemicals (EDCs) have been suggested to affect the differential fate of avian germ cells, there is currently no established method to examine the effects of EDCs on the differentiation potential of germline cells due to large amount of unidentified proteins present in avian germ cells. Regarding reliable molecular probes for the detection of germ cells that differentiated from the PGCs of Japanese quail, the prospermatogonium and oogonium, respectively, integrin beta1 (ITGB1), insulin-like growth factor 2-binding protein 1 (IGF2BP1), and stimulated by retinoic acid 8 (STRA8) were identified as marker proteins by RNA-seq and liquid chromatography tandem mass spectrometry analyses.

Background: The Hezuo (HZ) pig, a famous indigenous breed in China, is characterized by precocious puberty compared with foreign-introduced pig breeds. Sexual maturation is a complex physiological process, and in recent years, circular RNAs (circRNAs), a new class of noncoding RNAs with endogenous regulatory functions, have been shown to play important roles in regulating sexual maturation. However, the dynamic expression and regulatory mechanism of circRNAs during sexual maturation in HZ pigs remain unclear.

Undescended testis and testicular torsion represent two frequent andrological diseases that affect the pediatric age. Despite these testicular disorders having different causes, they both negatively influence fertility in adulthood mainly due to the accumulation of reactive oxygen species (ROS), which represents the primary molecular damage underlying their long-term effects. The gold standard of treatment for both pathologies is surgery; however, it cannot guarantee an optimal fertility outcome in all clinical cases, underscoring the need to identify effective adjuvant therapies that may target the augmented ROS levels.
