Varicocele can reduce male fertility potential through various oxidative stress mechanisms. Excessive production of reactive oxygen species may overwhelm the sperm's defenses against oxidative stress, damaging the sperm chromatin. Sperm DNA fragmentation, in the form of DNA strand breaks, is recognized as a consequence of the oxidative stress cascade and is commonly found in the ejaculates of men with varicocele and fertility issues. This paper reviews the current knowledge regarding the association between varicocele, oxidative stress, sperm DNA fragmentation, and male infertility, and examines the role of varicocele repair in alleviating oxidative-sperm DNA fragmentation in these patients. Additionally, we highlight areas for further research to address knowledge gaps relevant to clinical practice.

Purpose “Omics” techniques have been used to understand and to identify biomarkers of male infertility. We report on the first metabonomics models created to diagnose varicocele and infertility among men with varicocele. Methods We recruited 35 infertile men with varicocele (VI group), 21 fertile men with varicocele (VF group) and 24 fertile men without varicocele (C group). All men underwent standard semen analysis, scrotal duplex ultrasonography, and sexual hormone level measurement. Hydrogen-1 nuclear magnetic resonance (¹H NMR) spectra of seminal plasma were used to create metabonomics models to discriminate between men with and without varicocele, and between fertile and infertile men with varicocele. Results Using the statistical formalisms partial least square discriminants analysis and genetic algorithm–based linear discriminant analysis (GA-LDA), we created two models that discriminated the three groups from each other with accuracy of 92.17%. We also created metabonomics models using orthogonal partial least square discriminants analysis and GA-LDA that discriminated VF group from VI group, with an accuracy of 94.64% and 100% respectively. We identified 19 metabolites that were important in group segregation: caprate, 2-hydroxy-3-methylvalerate, leucine, valine, 3-hydroxybutyrate, lactate, alanine, 4-aminobutyrate, isoleucine, citrate, methanol, glucose, glycosides, glycerol-3-phosphocoline, n-acetyltyrosine, glutamine, tyrosine, arginine, and uridine. Conclusions ¹HNMR-based metabonomics of seminal plasma can be used to create metabonomics models to discriminate between men with varicocele from those without varicocele, and between fertile men with varicocele from those infertile with varicocele. Furthermore, the most important metabolites for group segregation are involved in the oxidative stress caused by varicocele.

Ejaculatory duct obstruction is a rare condition identified in up to 5% of infertile men. Patients with ejaculatory duct obstruction can present with aspermia, azoospermia or oligoasthenospermia, painful ejaculation, hematospermia, prostatic pain, or male infertility. Semen analysis, transrectal ultrasonography, pelvic computerized tomography and magnetic resonance imaging are often used in the diagnostic work up, but with limited accuracy. While transurethral resection of the ejaculatory ducts has good efficacy for distal duct obstruction, results for proximal obstruction are less impressive, and it might cause severe complications, such as rectal injury and urinary incontinence. Recently, the use of high quality endourological devices and an improved understanding of ejaculatory ducts anatomy gleaned through the use of sophisticated imaging tools have led to the development of novel minimally invasive treatment options for this condition. The present study aims to report an index case of ejaculatory ducts obstruction managed with seminal vesiculoscopy, and review the current literature regarding this topic.

Background: Human fertility has always been a topic of curiosity and devotion. Many cultures consider fertility to be a necessity for the survival and perpetuation of mankind and since early times, myths were created to explain this fabulous process. Fertility gods were ubiquitous in numerous ancient human cultures and were used both to understand fertility and to cope with infertility by means of rituals and offerings.Objectives: This manuscript aims to catalog and describe the deities associated with male fertility and virility.Material and methods: We conducted a comprehensive search for the terms “male fertility god” and “male virility god” on the internet using web‐based search engines. Based on the information retrieved, we selected those deities directed related to male fertility and/or virility and further deepened the search using Pubmed and Medline databases for peer‐reviewed articles as well as books and articles about ancient mythology.Results: We identified several gods linked to male fertility and virility in various cultures from Egypt, Greece, Rome, India, Southwestern United States, France, Colombia and Buthan..Discussion: Most of these deities were depicted with an erect phallus and with other fertility symbols like snakes. Some deities were also associated with plants and/or animal fertility and their festivals were often held during the harvest period.Conclusion: Gods of male fertility and virility played important roles in many ancient cultures. Offerings and rituals to these gods were the only available options to deal with problems of reproduction and demonstrate the lengths to which ancient people would go seeking cures for infertility.
