-Coffee Perks Up Sperm 2003-10-15Posted by clype in Health, Statistics.
Men who start the day with a shot of caffeine have more vigorous sperm than those who never drink coffee, according to researchers in Brazil.
The findings suggest men with fertility problems could benefit from a coffee break and that caffeine-based stimulants could be used to improve sperm samples used in IVF procedures.
In the study, at the University of Sao Paulo, a research team led by Fabio Pasqualotto, analysed the semen of 750 men who attended the university’s clinic for vasectomies.
All the coffee drinkers tended to have stronger and more powerful sperm than those who did not. The results were presented at the American Society for Reproductive Medicine conference in San Antonio. Euan Paul, of the Coffee Science Information Centre, said:
‘These findings are very exciting.
‘If sperm don’t swim well they tend to be more lethargic — they give up before they reach their goal. It seems caffeine makes them swim faster’.
