Dipartimento di Medicina e Chirurgia Traslazionale, Università Cattolica del S. Cuore, 00168 Rome, Italy.

Oxidative and inflammatory damage underlie several conditions related to male infertility, including varicocele. Free light chains of immunoglobulins (FLCs) are considered markers of low-grade inflammation in numerous diseases. Coenzyme Q10 (CoQ10), a lipidic antioxidant and anti-inflammatory compound, is involved in spermatozoa energy metabolism and motility. Read More

[Vitamin B12 is a diagnostic marker of decreased men reproductive function].

Biomed Khim 2022 Jun;68(3):228-231

Academician I.P. Pavlov Ryazan State Medical University, Ryazan, Russia.

Although the relationship between the amount of vitamin B12 and the quality of sperm exists, but results are controversial and require several additional research. The objective of our study was to analyse the amount of vitamin B12 in the sperm samples from patients with chronic prostatitis and varicocele with accompanying asthenozoospermia, and to identify the relationship between the amount of vitamin B12 and asthenozoospermia. The research was carried out of men with chronic prostatitis and varicocele with accompanying asthenozoospermia and infertility at the age of 27±2 years. Read More

Oxidative Stress and Varicocele-Associated Male Infertility.

Adv Exp Med Biol 2022 ;1358:205-235

S. H. Ho Urology Centre, Department of Surgery, The Chinese University of Hong Kong, Hong Kong, Hong Kong.

Despite being regarded as one of the most common causes of male subfertility, the pathophysiology of varicocele remains largely unknown. Recently, oxidative stress (OS) is proposed to be the mediator in how varicocele may negatively impact fertility. The imbalance of reactive oxygen species (ROS) and seminal antioxidants results in damage to sperm DNA and lipid membrane. Read More

Pathological Roles of Reactive Oxygen Species in Male Reproduction.

Adv Exp Med Biol 2022 ;1358:41-62

Department of Life Science and Bioinformatics, Assam University, Silchar, India.

Reactive oxygen species (ROS) are free radicals that have at least one unpaired electron and play specific roles in the human body. An imbalance of ROS and antioxidant levels gives rise to a condition called oxidative stress. High levels of ROS in the male reproductive tract can interfere with its normal functioning and can even pose as toxic to the sperm, inhibiting sperm functioning (including motility) and metabolism.

The NLRP3 inflammasome: molecular activation and regulation in spermatogenesis and male infertility; a systematic review.

Basic Clin Androl 2022 May 30;32(1). Epub 2022 May 30.

Department of Animal Biotechnology, Reproductive Biomedicine Research Center, Royan Institute for Biotechnology, ACECR, Isfahan, Iran.

Background: Infertility related to varicocele, infections, metabolic dysfunctions, oxidative stress and environmental toxicants is also associated with inflammatory processes that ultimately lead to the activation of the inflammasome pathway (IP). IP is classically activated by DAMPs, MAMPs or LAMPs, which stand for Damage-, Microbe- or Lifestyle-Associated Molecular Patterns, respectively. The most important player in IP activation is the NLRP3 (NOD[Nuclear oligomerization domain]-, LRR[Leucine rich repeat]- and pyrin domain-containing protein 3) which functions as an intracellular sensor of D/M/L-AMPs resulting in activation of caspase-1, promotion of apoptosis, pyroptosis and generation of inflammatory cytokines.

Role of Oxidative Stress in Varicocele.

Front Genet 2022 23;13:850114. Epub 2022 Mar 23.

School of Life Science, Bengbu Medical College, Bengbu, China.

According to the official statistics of the World Health Organization, at least 48 million couples and 186 million people suffer from infertility. Varicocele has been recognized as the leading cause of male infertility and can affect spermatogenesis and cause testicular and epididymal disorders through multiple diverse pathophysiological processes.

Predictors of microsurgical varicocelectomy efficacy in male infertility treatment: critical assessment and systematization.

Asian J Androl 2022 Mar 29. Epub 2022 Mar 29.

Department of Urology and Andrology, Faculty of Fundamental Medicine, Lomonosov Moscow State University, Moscow 119991, Russia.

In this review, we tried to systematize all the evidence (from PubMed [MEDLINE], Scopus, Cochrane Library, EBSCO, Embase, and Google Scholar) from 1993 to 2021 on the predictors of microsurgical varicocelectomy efficacy in male infertility treatment. Regarding the outcomes of varicocele repair, we considered semen improvement and pregnancy and analyzed them separately. Based on the 2011 Oxford CEBM Levels of Evidence, we assigned a score to each trial that studied the role of the predictor. Read More

J Inflamm Res 2022 26;15:2019-2031. Epub 2022 Mar 26.

Department of Molecular and Developmental Medicine, University of Siena, Siena, Italy.

Purpose: Omentin-1/intelectin (ITLN)1 is an adipocytokine with both anti-inflammatory and anti-oxidative stress properties, and little is known about its role in male reproduction. This study was aimed at exploring the relationships among omentin-1/ITLN1, semen parameters and F-isoprostanes (F-IsoPs), a maker of oxidative stress, in groups of patients affected by different pathologies. In addition, omentin-1/ITLN1 immunolocalization was assessed in ejaculated spermatozoa and in tissues of male reproductive system. Read More

Pathogenesis of Autoimmune Male Infertility: Juxtacrine, Paracrine, and Endocrine Dysregulation.

Pathophysiology 2021 Oct 15;28(4):471-488. Epub 2021 Oct 15.

Laboratory of the Mosaics of Autoimmunity, Saint Petersburg State University, 199304 Saint Petersburg, Russia.

According to global data, there is a male reproductive potential decrease. Pathogenesis of male infertility is often associated with autoimmunity towards sperm antigens essential for fertilization. Antisperm autoantibodies (ASAs) have immobilizing and cytotoxic properties, impairing spermatogenesis, causing sperm agglutination, altering spermatozoa motility and acrosomal reaction, and thus preventing ovum fertilization.
