Abstract
The paper presented and discussed the general evolutionary understandings of post-copulatory competition issues that are found among males when they are competing who is going to be the first, as well as the last, to having intimate contact with females. In particular, the whole discussion of this article focuses on the presence, or not, of male sperm within a female's reproductive tract. Examples about post-copulatory competition are provided from both insects and vertebrates. What is also discussed is that such competition between males takes place in view to the passing on of genes that carry traits able to bring upon reproductive success to future generations via sexually-selected strategies towards the ultimate goal of fertilisation of females' reproductive tracts.
