The new 6th edition of the WHO laboratory manual for the examination and processing of human semen: Is it a step toward better standard operating procedure?
(Shanghai Institute Materia Medica, 2021)Semen analysis (SA) remains the cornerstone of male infertility evaluation and should ideally be performed by an accredited andrology laboratory or in vitro fertilization (IVF) clinics based on the standards defined ... -
Overview of the effects of moringa oleifera leaf extract on oxidative stress and male infertility: a review
(MDPI, 2023)According to a recent report by the WHO, 50–80 million people suffer with infertility. Amongst these populations, male counterparts account for 20–50% of infertility cases. The aetiology of infertility in men includes many ... -
Proteomics and metabolomics — Current and future perspectives in clinical andrology
(Blackwell Publishing Ltd, 2021)Proteomics and metabolomics are emerging as promising tools to investigate the molecular mechanisms associated with male infertility. Proteins and metabolites play a pivotal role in regulating the molecular pathways ... -
Radiations and male fertility
(Springer Nature, 2018)During recent years, an increasing percentage of male infertility has to be attributed to an array of environmental, health and lifestyle factors. Male infertility is likely to be affected by the intense exposure to heat ... -
Reactive oxygen species and male reproductive hormones
(BMC, 2018)Reports of the increasing incidence of male infertility paired with decreasing semen quality have triggered studies on the effects of lifestyle and environmental factors on the male reproductive potential. There are ... -

Reactive oxygen species in male reproduction: A boon or a bane?
(Blackwell Publishing Ltd, 2021)Reactive oxygen species (ROS) are free radicals derived from oxygen during normal cellular metabolism. ROS play a crucial role in the physiological processes and signalling pathways associated with male fertility. At ... -
Reactive oxygen species in male reproduction: A boon or a bane?
(Wiley, 2020)Reactive oxygen species (ROS) are free radicals derived from oxygen during normal cellular metabolism. ROS play a crucial role in the physiological processes and signalling pathways associated with male fertility. At ... -
Relevance of leukocytospermia and semen culture and its true place in diagnosing and treating male infertility
(Korean Society for Sexual Medicine and Andrology, 2021)The current WHO 2010 manual for human semen analysis defines leukocytospermia as the presence of peroxidase-positive leukocytes at a concentration >1×106 /mL of semen. Granular leukocytes when activated are capable of ... -
Role of cytocentrifugation combined with nuclear fast picroindigocarmine staining in detecting cryptozoospermia in men diagnosed with azoospermia
(Seoul: Korean Society for Sexual Medicine and Andrology, 2022)Azoospermia is defined as the absence of spermatozoa in the pellet of a centrifuged semen sample. In fact, when a basic semen analysis fails to detect sperm in the ejaculate, there is still the possibility of detecting ... -
The role of infections and leukocytes in male infertility
(Blackwell Publishing Ltd, 2021)Declining birth rates are one of the problems facing society today. Male counterparts are responsible for about half of the infertility cases, and genitourinary tract infections may play a contributing role in approximately ... -
Scientific landscape of oxidative stress in male reproductive research: A scientometric study
(Elsevier, 2020)Unraveling the role of reactive oxygen species and associated oxidative stress (OS) in male reproduction is one of the key areas of male reproductive research. This article illustrates the scientific landscape of OS in ... -
A scientometric analysis of research publications on male infertility and assisted reproductive technology
(Blackwell Publishing Ltd, 2021)Assisted reproductive technologies (ART) are considered as one of the primary management options to address severe male factor infertility. The purpose of this study was to identify the research trends in the field of male ... -
Seminal oxidation–reduction potential levels are not influenced by the presence of leucocytospermia
(Wiley-Blackwell, 2020)Oxidative stress (OS) is characterised by an excessive amount of reactive oxygen species (ROS) which negatively affect sperm functions. In this study, the influence of leucocytes on seminal oxidation–reduction potential ... -
Total antioxidant capacity—Relevance, methods and clinical implications
(Blackwell Publishing Ltd, 2021)Oxidative stress is pre-empted by an adequate level of antioxidants, which scavenge oxidants when they are produced in excess by different sources, including leukocytes and immature spermatozoa. Enzymatic antioxidants, ... -

TUNEL assay—Standardized method for testing sperm DNA fragmentation
(Blackwell Publishing Ltd, 2021)Sperm DNA integrity is important for normal functions such as fertilization, implantation, pregnancy and fetal development. Sperm DNA fragmentation (SDF) is more common in infertile men and may be responsible for poor ...
