Bovine seminal plasma SP is known to have an effect on spermatozoa and the female reproductive tract. Ytterligare studier behövs för att undersöka de faktorer som är inblandade i samspelet mellan SP och spermier eller bEEC, såsom skillnader i sammansättningen hos SP mellan låg- och högfertila tjurar, ras och ålder hos tjurarna samt faktorernas effekter på fertiliteten.
