天天做爱 有没有帮助精子发育??
新研究发现，精虫品质不佳的男人应该每天射精，才能增加其配偶受孕的机会。
现行观念认为，如果因丈夫的精虫问题导致妻子难以怀孕，丈夫在行房前最好先禁欲几天以增加精虫数目，从而增加受孕机会。但澳洲雪梨大学一个研究团队十六日在“美国生殖医学学会”于华府举行的研讨会席间发表报告说，禁欲反而会使精虫的品质更糟。
雪梨大学研究团队以四十二名男子为研究对象，这些人的精虫在显微镜底下呈现异常形状，研究员要他们连续射精七天，将这些精虫和他们禁欲三天后射精的精虫比对，结果发现除五人外，其他人每天射精的精虫DNA（去氧核糖核酸）比禁欲后的精虫DNA较少受损。
发表这项研究报告的葛林宁博士说，他相信射精越频繁，越能相当程度改善大多数男人精虫DNA受损的问题。这项研究还在初步阶段，研究人员对两种精虫造成受孕的比率并未做过比较，如果要做试管受孕，某些男人每天射精所提供的精子可能成功的机会较大。
在英国雪非尔大学任泌尿科高级讲师的佩西说，精虫品质和数量不能兼得，当精虫DNA受损严重时，自然是出清存货比较重要。
