Contrary to popular belief, the fastest sperm don\u2019t always finish first. Various chemicals in the female reproductive system can also determine which sperm are successful, according to a new study published Wednesday in the journal Proceedings of the Royal Society B.<\/p>\n

\n\u201cThe whole reproductive tract of the female seems to have evolved to filter out \u2018unwanted\u2019 spermatozoa,\u201d Jukka Kek\u00e4l\u00e4inen, a biology professor at the University of Eastern Finland who co-authored the study, told CNN.<\/p>\n

Specifically, the cervix acts as a reproductive bouncer of sorts \u2014 both rejecting \u201cabnormal\u201d sperm, while aiding swimmers that give the woman\u2019s offspring the best chance of survival, per the research. A prior study by the same team found that a woman\u2019s follicular fluid serves the same purpose, CNN reports.<\/p>\n

To test the organ\u2019s selective function, the team combined all possible variations of cervical fluid of nine women with the sperm of eight men, and then compared swimmers\u2019 finishing rate to the genotype of each participant.<\/p>\n<\/div>\n

Interestingly, they found that the most compatible sperm were also the least genetically similar to the egg. The phenomenon can be chalked up to the fact that \u201cthe more diverse those genes are, the more diverse are the kinds of infections you can fight,\u201d said John Fitzpatrick, an associate\u00a0<\/strong>professor in the department of zoology at Stockholm University in Sweden.<\/p>\n

He added, \u201cIf your partner has a slightly different combination of these genes than you do, then you\u2019re going to produce offspring that can fight an even broader array of pathogens and diseases.\u201d So yes, diversity is a sperm\u2019s greatest strength.<\/p>\n

Most importantly, the game<\/a>-changing research could help doctors more accurately diagnose why certain couples can\u2019t conceive.<\/p>\n

\u201cWe would encourage future infertility research to test the possibility that infertility is not always a pathological condition, but instead can also result in demonstrated evolutionary mechanism,\u201d said Kek\u00e4l\u00e4inen.<\/p>\n

Reproductive fluids aren\u2019t the only chemical indicators of whether a mate is viable. Studies show that the scent of one\u2019s sweat plays a crucial role when it comes to picking sex partners.\n <\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n
