The Effect of Varicocele Treatment on Fertility in Adults: A Systematic Review and Meta-analysis of Published Prospective Trials. Eur Urol Focus 2023; 9:154-161. [PMID: 36151030 DOI: 10.1016/j.euf.2022.08.014] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2022] [Revised: 07/18/2022] [Accepted: 08/30/2022] [Indexed: 11/25/2022]
Abstract
CONTEXT The benefits and harms of varicocele treatment versus observation in adult infertile males are still controversial. OBJECTIVE To systematically pool the evidence on outcomes of varicocele treatment (any surgical or radiological) versus observation in adult infertile men. EVIDENCE ACQUISITION A systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Only prospective randomized and nonrandomized studies were included until November 2021. The primary outcome was pregnancy rate; the secondary outcomes were improvements in sperm concentration, normal morphology, and progressive sperm motility after treatment compared to baseline. Men ≥18 yr of age with any-grade varicoceles were included. EVIDENCE SYNTHESIS Of 557 articles identified, 12 were eligible for inclusion, involving 1357 patients. Varicoceles were treated surgically in ten and radiologically in four studies. Varicocele treatment improved pregnancy rates (odds ratio 1.29; 95% confidence interval [CI] 1.00-1.65; p = 0.048) and sperm concentration (mean difference 12.34 million/ml, 95% CI 3.49-21.18; p = 0.006) compared with observation. Proportions of spermatozoa with normal morphology and progressive motility were not statistically different from those with observation. However, considering treatment arm only, sperm concentration, progressive motility, and normal sperm morphology were improved compared with baseline. A subgroup analysis showed that the benefit of varicocele treatment is evident in men with an abnormal semen analysis. The main limitation is represented by the heterogeneity of the included studies, mostly in terms of study population, fertility of the partner, outcome evaluation, lack of long-term outcomes, and intermediate/high risk of bias. CONCLUSIONS Treatment of any-grade varicoceles may improve pregnancy rates and sperm concentration in adult infertile men, while benefits in sperm motility and normal morphology are less clear. PATIENT SUMMARY In this systematic review and meta-analysis of all published prospective trials on varicocele treatment, significant evidence emerged on its benefit in terms of improved pregnancy rates and sperm concentration, while benefits in sperm motility and morphology are less clear.

The European Academy of Andrology (EAA) ultrasound study on healthy, fertile men: An overview on male genital tract ultrasound reference ranges. Andrology 2022; 10 Suppl 2:118-132. [PMID: 35930758 PMCID: PMC9828651 DOI: 10.1111/andr.13260] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2022] [Revised: 07/29/2022] [Accepted: 07/29/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND So far, male genital tract color-Doppler ultrasound (MGT-CDUS) was not standardized. Recently, the European Academy of Andrology (EAA) published the results of a multicenter study assessing the CDUS characteristics of healthy-fertile men (HFM) to obtain normative parameters. OBJECTIVES To report the EAA US study (i) standard operating procedures (SOPs) for assessing MGT-CDUS, (ii) main MGT-CDUS normative parameters, and (iii) compare the EAA and previously published "normal" CDUS values. METHODS A cohort of 248 HFM (35.3 ± 5.9 years) was studied, evaluating MGT-CDUS before and after ejaculation following SOPs. RESULTS SOPs for MGT-CDUS assessment are summarized here. All subjects underwent scrotal CDUS and 188 men underwent transrectal ultrasound before and after ejaculation. The main CDUS reference ranges and characteristics of the HFM-MGT are reported here. The mean testicular volume was ∼17 mL. The lower limit for right and left testis was 12 and 11 mL, defining testicular hypotrophy. The upper limit for epididymal head, body, tail, and vas deferens was 11.5, 5, 6, and 4.5 mm, respectively. Testicular and epididymal arterial reference ranges are reported. The EAA varicocoele classification is reported. CDUS-varicocoele was detected in ∼37% of men. Prostate mean volume was ∼25 mL, while lower and upper limits were 15 and 35 mL, defining hypotrophy and enlargement, respectively. Prostate arterial reference ranges are reported. Prostate calcifications and inhomogeneity were frequent; midline prostatic cysts were rare and small. Ejaculatory duct abnormalities were absent. The upper limit for periprostatic venous plexus was 4.5 mm. Lower and upper limits of seminal vesicles (SV) anterior-posterior diameter were 6 and 16 mm, defining hypotrophy or dilation, respectively. Seminal vesicle volume and ejection fraction reference ranges are reported. SV-US abnormalities were rare. Deferential ampullas upper limit was 6 mm. A discussion on the EAA and previously published "normal" CDUS values is reported here. CONCLUSIONS The EAA findings will help in reproductive and general male health management.

[PMID: 36040837 DOI: 10.1111/andr.13278] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2021] [Revised: 08/18/2022] [Accepted: 08/18/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Varicocele is a common risk factor associated with reduced male fertility potential. The current understanding of varicocele pathophysiology does not completely explain the clinical manifestation of infertility. The present treatment options such as antioxidant supplementation and varicocelectomy only helps ∼35% of men to achieve spontaneous pregnancy. OBJECTIVE This review aims to summarize the available knowledge on cellular and molecular alterations implicated to varicocele associated male infertility and also highlights the new knowledge generated by 'Omics' technologies. MATERIALS AND METHODS PubMed, MEDLINE, Cochrane and Google Scholar databases are searched using different combinations of keywords (varicocele, infertile/fertile men with varicocele, cellular changes, molecular mechanisms, proteome, epigenome, transcriptome and metabolome). A total of 229 relevant human and animal studies published till 2021 were included in this review. RESULTS Current understanding advocates oxidative stress (OS) as a major contributory factor to the varicocele associated male infertility. Excessive OS causes alteration in testicular microenvironment and sperm DNA fragmentation which further contributes to infertility. Molecular and omics studies have identified several promising biomarkers such as AAMP, SPINT1, MKI67 (genetic markers), sperm quality and function related protein markers, global sperm DNA methylation level (epigenetic marker), Hspa2, Protamine, Gadd7, Dynlt1 and Beclin1 (mRNA markers), PRDX2, HSPA, APOA2, YKL40 (seminal protein markers), total choline and PHGDH (metabolic markers). DISCUSSION Mature spermatozoa harbours a plethora of molecular information in form of proteome, epigenome and transcriptome; which could provide very important clues regarding pathophysiology of varicocele associated infertility. Recent molecular and omics studies in infertile men with varicocele have identified several promising biomarkers. Upon further validation with larger and well-defined studies, some of these biomarkers could aid in varicocele management. CONCLUSION The present evidences suggest inclusion of OS and sperm DNA fragmentation tests could be useful to the diagnostic workup for men with varicocele. Furthermore, including precise molecular markers may assist in diagnostics and prognostics of varicocele associated male infertility. This article is protected by copyright. All rights reserved.
