Reasons for worldwide decline in male fertility.
TLDR
There exist substantial data to suggest a decline in sperm counts over time, although causative factors have yet to be fully elucidated, potential causes include, increased rates of obesity, poor diet, and exposure to environmental toxins.Abstract:
Purpose of review To review the evidence regarding a decrease in worldwide sperm parameters and discuss potential causative factors. Recent findings The topic of worldwide decline in sperm parameters is contentious; however, recent high-quality studies have demonstrated that there is indeed a decline in sperm parameters. Several retrospective and basic science studies have shown possible links for this decline in sperm parameters such as obesity, diet, and environmental toxins. Summary There exist substantial data to suggest a decline in sperm counts over time. Although causative factors have yet to be fully elucidated, potential causes include, increased rates of obesity, poor diet, and exposure to environmental toxins. How this decline in sperm counts reflects fertility has yet to be determined. As such, further studies are necessary to evaluate whether this decline in sperm count correlates with decreased fecundity and how to identify and mitigate potential causative factors.read more

TL;DR: In this article, the effect of a lifestyle intervention on semen quality of healthy young men living in highly polluted areas of Italy was evaluated using a randomized controlled trial, where the intervention group followed a 4-mo Mediterranean diet and moderate physical activity program, at which the participants showed an improvement of semen quality parameters.

Luigi Montano,Francesco Donato,Pietro Massimiliano Bianco,Gennaro Lettieri,Antonino Guglielmino,Oriana Motta,Ian Marc Bonapace,Marina Piscopo +7 more
TL;DR: In this paper, a review article summarizes the relevant current observations emphasizing the weight that environmental pollution has on the sensitivity of a given population to several diseases and how semen quality, may be a potential indicator of sensitivity for virus insults in high polluted areas, and help to predict the risk for harmful effects of the SARS-CoV-2 epidemic.

Evidence for decreasing quality of semen during past 50 years.
TL;DR: There has been a genuine decline in semen quality over the past 50 years, and as male fertility is to some extent correlated with sperm count the results may reflect an overall reduction in male fertility.

TL;DR: The measurements showed that nanogrooving increases the surface area of carbon microtubes, as a result, die swelling of the extrudate is reduced and the mechanical strength of composite is reinforced due to stronger interactions between Nanogrooved carbon tubes and polymer matrix.
