Phthalate esters and semen quality parameters
Biological Mass Spectrometry, 1987Analysis of reports in the world's literature suggests that average sperm densities for groups of unselected males were relatively constant at about 108 million cells per ml prior to 1950. Subsequent to that time mean sperm densities appear to have declined.

Assessing poultry semen quality
2023This overview briefly examines some of the semen evaluation techniques and fertility determination procedures used currently on breeder farms. The later procedures were included as both provide rapid feedback on flock fertility, the best indicator of semen quality.

Stainless steel welding and semen quality
Reproductive Toxicology, 1988Questionnaire studies of patients from fertility clinics suggest that welders may have an increased risk of reduced semen quality. In this study, welders and nonwelders from the same plants were asked to provide blood, urine, and semen samples. Urine was analyzed for chromium and nickel, and for mutagenic activity and metal concentration; blood for ...

Infertility affects an estimate of 50–80 × 106 (=7–15% of men at reproductive age) men globally and annually. Among these men, a large number of patients (25–40%) suffer from male genital tract infection/inflammation, conditions where reactive oxygen species (ROS) and oxidative stress in the semen play prominent roles in the pathogenesis of infertility.

Effect of paracetamol on semen quality
Andrologia, 2017Several published studies, both direct and indirect, have connected paracetamol, also named acetaminophen, a commonly used over-the-counter analgesic and antipyretic medication, with semen quality and male infertility, although as yet this connection is unclear.

Quality assurance applied to semen analysis
Animal Reproduction ScienceArtificial insemination is an important biotechnology employed in livestock production. Production of semen products requires analysis of sperm concentration, motility and morphology. Although adequate analytical procedures are essential to ensure product quality, several multicenter studies have reported large variations in semen analysis results ...

The goal of research in laboratory evaluation of semen has been to ultimately predict the fertility achievable with use of that semen. Historically, problems deterring realization of this goal include pitfalls in experimental approach as well as a lack of basic understanding of biological mechanisms important to the relationship between semen quality ...
