High levels of oxidation–reduction potential in frozen-thawed human semen are significantly correlated with poor post-thaw sperm quality
(Wiley-Blackwell, 2020)
This study examined the relationship between oxidation–reduction potential (ORP) in frozen-thawed semen and the post-thaw sperm parameters. Levels of ORP were measured in 25 samples from men presenting for routine infertility ...
Novel additive for sperm cryopreservation media: Holotheria parva coelomic cavity extract protects human spermatozoa against oxidative stress—A pilot study
(Wiley-Blackwell, 2020)
Cryopreservation is the most effective method for preserving semen for a long period of time. However, during the freeze–thaw process, production of reactive oxygen species (ROS) leads to a steep reduction in sperm fertility ...
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 ...
Quest for the best—a move to anatomical endoscopic enucleation of the prostate
(Wiley-Blackwell, 2020)
The history of surgical enucleation for the treatment of lower urinary tract symptoms caused by benign prostatic enlargement dates back more than 100 years (Freyer, 1919). Open prostatec-tomy (OP) is an invasive procedure ...
PICSI vs. MACS for abnormal sperm DNA fragmentation ICSI cases: A prospective randomized trial
(Springer Nature, 2020)
Purpose: To know which sperm selection technique, physiological intracytoplasmic sperm injection (PICSI) or magnetic-activated cell sorting (MACS), is better for the selection of sperm with abnormal sperm DNA fragmentation ...
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 ...
The effect of Nigella sativa oil and metformin on male seminal parameters and testosterone in Wistar rats exposed to an obesogenic diet
(Elsevier, 2020)
Obesity is a significant global health and socio-economic challenge, and considered an important risk factor for poor health outcomes including male reproductive dysfunction and infertility. As excess adiposity causes ...
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 ...
Total antioxidant capacity—Relevance, methods and clinical implications
(Blackwell Publishing Ltd, 2020)
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, ...
Ritalinic acid stimulates human sperm motility and maintains vitality in vitro
(Korean Society for Sexual Medicine and Andrology, 2020)
To evaluate the in vitro impact of ritalinic acid (RA), a major metabolite of methylphenidate (drug to treat attention-deficit hyperactivity disorder), on sperm motility, vitality and oxidative stress. Materials and Methods: ...
