On average, they had 25.6 million fewer sperm per ejaculation compared to those eating the healthiest diets.

平均而言，这些男性每次射精数量比饮食最健康的男性少2560万。

While previous studies have focused on older men trying to conceive, this research shows some men have “clinically low” sperm counts despite being at their peak reproductive age.

先前的研究关注的是想要孕育下一代的年长男性，但这项研究表明，尽管处于最佳生育年龄，一些男性的精子数量“临床结果很低”。

What’s more, men eating junk food diets were found to have diminished levels of Sertoli cells – a type of cell contained in the testicles which is associated with producing healthy sperm.

此外，研究发现，吃垃圾食品的男性塞尔托利氏细胞水平偏低。塞尔托利氏细胞是睾丸中所含的一种与制造健康精子有关的细胞。

Eating a junk food diet causes oxidative damage to these cells, it was found, and this cannot be reversed in later life.

研究发现，吃垃圾食品会对这些细胞造成氧化损伤，而且这些损伤无法在以后逆转。

The research will be presented at the European Society for Human Reproduction and Embryology (ESHRE) annual conference in Vienna.

这项研究将在维也纳举行的欧洲人类生殖与胚胎学学会的年会上展示。
