Antioxidant Supplements May not Improve Sperm Quality: Study

Further, the natural conception rate during the initial three month was 10.5 per cent in the antioxidant group and a little more than nine per cent in the placebo group

Scientists have found that consuming antioxidant supplement daily for three months does not help improve the sperm quality among infertile men as previously thought and thus cannot be considered as a therapy.

According to the authors, spermatogenesis — production or development of the mature spermatozoa — and transport together take approximately 74 days, but that reactive oxygen species have a greater negative effect during the much shorter sperm transport phase rather than during spermatogenesis, thus antioxidants are thought to have benefit even after a short interval.

“The results do not support the empiric use of antioxidant therapy for male factor infertility in couples trying to conceive naturally,” said Anne Steiner, Professor at the University of North Carolina at Chapel Hill, US.

For the study, presented at the 34th Annual Meeting of ESHRE in Barcelona, the team conducted clinical trail of 174 couples where the male partners took daily antioxidant supplement in tablet form containing vitamins C, D3 and E, folic acid, zinc, selenium and L-carnitine, while the control group received a placebo.

The findings showed only a “slight” overall difference in sperm concentration between the two groups, and no significant differences in morphology — the shape and size of the sperm cells –, motility — the ability of sperm to swim or move –, or DNA fragmentation measurements — damage in the DNA of the sperm.

Further, the natural conception rate during the initial three month was 10.5 per cent in the antioxidant group and a little more than nine per cent in the placebo group, the researchers said. (IANS)

Hot Coffee Has Higher Levels of Antioxidants Than Cold Coffee

And considering hot and cold brews have comparable pH levels, coffee drinkers should not consider cold brew a 'silver bullet' for avoiding gastrointestinal distress

Hot coffee has higher levels of antioxidants than cold coffee, which are believed to be responsible for some health benefits, says a new study.

The study explored that hot coffee has some measurable health benefits, including lower risk of some cancers, diabetes and depression.

For the study, researchers from Thomas Jefferson University in the US showed that hot coffee had more total titratable acids — any acid that can lose proton(s) in an acid-base reaction — which may be responsible for the hot cup’s higher antioxidant levels.

“Coffee has a lot of antioxidants. If you drink it in moderation, research shows it can be pretty good for you. We found the hot brew has more antioxidant capacity,” said Megan Fuller, an Assistant Professor from the varsity.

Results published in the journal “Scientific Reports” also found that pH levels — acidity indicator– of both hot and cold coffee were similar, ranging from 4.85 to 5.13 for all coffee samples tested.

However, coffee companies and lifestyle blogs have tended to tout cold brew coffee as being less acidic than hot coffee and thus less likely to cause heartburn or gastrointestinal problems.
