I came across this abstract but have attached the paper but not read it. In the results infertile women consumed more polyunsaturated fat (OR 1.23), less saturated fat (OR 0.83) and had more hangovers (OR 1.02), a significant but marginal effect (2%). But the conclusions say that alcohol use is something that needs to be addressed. There was stuff on the BBC website yesterday that alcohol consumption has decreased since 2004... But hey, you can't mention polyunsaturated fat being bad for you!
Pass the butter.
