美国研究人员最近研究发现,如果男性每天喝1品脱啤酒,当上父亲的几率能够翻倍。不过,研究人员还发现,如果要组建一个家庭,少喝咖啡可能是个好主意,每天仅喝两杯咖啡似乎就会降低夫妇的生育几率。另一项研究发现,素食者的精子数量要少于正常饮食者,而且质量也较差。 A recent study by U.S. researchers found that men who drank 1 pint of beer a day could double their chances of becoming fathers. However, the researchers also found it might be a good idea to drink less coffee if a family was to be set up, and it seemed likely that drinking only two cups of coffee a day would reduce the couple’s chances of giving birth. Another study found that vegetarians have fewer sperm than normal diet and poor quality.
