Aiming for a clinical pregnancy? Scientists suggest a bit of booze…
Yesterday Boston researchers reported at the Annual Meeting of the American Society for Reproductive Medicine (ASRM) that they have found "interesting connections" between male partners’ beverage consumption and clinical pregnancy rates after in-vitro fertilization (IVF).
Analysing dietary, health and lifestyle data for men undergoing IVF at Massachusetts General Hospital from 2007-2013, Karmon et al. found that couples with male partners whose caffeine intake hit the highest range (265mg+ caffeine/day) were only half as likely to have a clinical pregnancy as couples where the male consumed less than 88mg of caffeine/day.
Moreover, alcohol intake (up to and above 22g of alcohol/day) was positively associated with clinical pregnancy success.
“Although there is extensive literature on the relationship between beverage intake and semen parameters, little data exists on male caffeine and alcohol intake and pregnancy outcomes. Our results suggest that male caffeine and alcohol intake," the scientists write, in their newly published study in 'Fertility and Sterility'.
