Take the common species Macrostomum lignano. After sex, if a female has been filled with unwanted sperm from an undesirable partner, it can double over, put its mouth over its genital opening, and suck the sperm back out. It\u2019s an easy fix that gives the female control over who fertilises her eggs.

\n But the sperm can put up a fight. It has a very different shape to the tadpole-like figure of human sperm. At its front, it has a sinuous \u2018feeler\u2019 that is uses to anchor itself into the walls of the female genitals. Further down, two large backwards-pointing bristles also help to hold the sperm in place. These barbed sperm can\u2019t be sucked out easily.<\/p>\n<\/blockquote>\n\n

Prenez l’esp\u00e8ce commune Macrostomum lignano. Apr\u00e8s une relation sexuelle, si une femelle a \u00e9t\u00e9 remplie par du sperme d’un partenaire non d\u00e9sir\u00e9, elle peut se replier sur elle-m\u00eame, mettre sa bouche sur l’ouverture de ses parties g\u00e9nitales et sucer le sperme. C’est une solution simple qui donne le contr\u00f4le \u00e0 la femelle sur qui fertilise ses oeufs.

\n Mais le sperme peut r\u00e9sister. Il a une forme tr\u00e8s diff\u00e9rente du sperme humain en forme de t\u00eatard. Devant, il a une antenne sinueuse qu’il utilise pour s’ancrer dans les parois g\u00e9nitales de la femelle. Plus loin, deux ‘moustaches’ point\u00e9es vers l’arri\u00e8re aident aussi \u00e0 garder le sperme en place. C’est spermes “barbel\u00e9s” ne peuvent pas \u00eatre facilement suc\u00e9s.<\/p>\n<\/blockquote>\n\n
