Les techniques conventionnelles de s\u00e9lection des spermatozo\u00efdes<\/strong> utilis\u00e9es en procr\u00e9ation m\u00e9dicalement assist\u00e9e (swim-up et gradients de densit\u00e9) reposent sur la r\u00e9cup\u00e9ration ou la s\u00e9lection de ceux qui pr\u00e9sentent la meilleure motilit\u00e9 et la meilleure morphologie.<\/p>\n

Dans certains cas, les spermatozo\u00efdes pr\u00e9sentant une forme ou une motilit\u00e9 normales peuvent pr\u00e9senter un indice \u00e9lev\u00e9 de stress oxydatif et de fragmentation de leurs cha\u00eenes d’ADN<\/strong>, deux param\u00e8tres qui ne sont pas d\u00e9tect\u00e9s lors d’une analyse s\u00e9minale conventionnelle. Ces alt\u00e9rations sont nettement plus fr\u00e9quentes chez les hommes hypofertiles pr\u00e9sentant des param\u00e8tres s\u00e9minaux alt\u00e9r\u00e9s, bien qu’elles puissent \u00e9galement \u00eatre observ\u00e9es chez des hommes aux param\u00e8tres s\u00e9minaux normaux.<\/p>\n

Il s’agit d’une situation qui survient lorsqu’il existe un d\u00e9s\u00e9quilibre entre les esp\u00e8ces r\u00e9actives de l’oxyg\u00e8ne (ERO)<\/strong> et le syst\u00e8me antioxydant. Les ERO sont des agents oxydants g\u00e9n\u00e9r\u00e9s au cours du m\u00e9tabolisme cellulaire normal.<\/p>\n

Un niveau \u00e9lev\u00e9 de stress oxydatif peut entra\u00eener un taux \u00e9lev\u00e9 de fragmentation de l’ADN<\/strong>, ce qui peut \u00eatre \u00e0 l’origine d’une infertilit\u00e9 masculine et compromettre les chances d’obtenir une grossesse naturelle, car l’int\u00e9grit\u00e9 g\u00e9n\u00e9tique du spermatozo\u00efde est essentielle au d\u00e9veloppement embryonnaire.<\/p>\n

Il existe diff\u00e9rents types de fragmentation de l’ADN spermatique<\/strong> : \u00e0 simple brin et \u00e0 double brin<\/strong>. Les cassures \u00e0 simple brin sont associ\u00e9es \u00e0 un taux de conception plus faible. En revanche, les cassures \u00e0 double brin n’emp\u00eachent pas la grossesse, mais peuvent entra\u00eener un risque accru de fausse couche.<\/p>\n

Le tri cellulaire par activation magn\u00e9tique (MACS)<\/strong>, \u00e9galement connu sous le nom de colonne \u00e0 annexine V<\/strong>, est une technique utilis\u00e9e pour \u00e9liminer les spermatozo\u00efdes pr\u00e9sentant des signes d’apoptose<\/strong> (mort cellulaire programm\u00e9e), g\u00e9n\u00e9ralement associ\u00e9s \u00e0 un stress oxydatif \u00e9lev\u00e9 provoquant une fragmentation de l’ADN.<\/p>\n

Chez les patients pr\u00e9sentant un taux \u00e9lev\u00e9 de fragmentation de l’ADN spermatique, on a observ\u00e9 qu’une proportion significative des spermatozo\u00efdes pr\u00e9sentait des l\u00e9sions cellulaires li\u00e9es \u00e0 des processus apoptotiques. Dans ces cas, la MACS<\/strong> agit comme une technique compl\u00e9mentaire de pr\u00e9paration du sperme, dont l’objectif est de r\u00e9cup\u00e9rer les spermatozo\u00efdes ne pr\u00e9sentant pas de marqueurs d’apoptose et de s\u00e9lectionner ceux qui ont la plus grande viabilit\u00e9 et le plus grand potentiel de f\u00e9condation pour une utilisation dans les proc\u00e9dures de procr\u00e9ation m\u00e9dicalement assist\u00e9e.<\/p>\n

S\u00e9lection du sperme par microfluidique ou microcanaux.<\/strong><\/h4>\n

Les syst\u00e8mes de s\u00e9lection spermatique bas\u00e9s sur la microfluidique ou le passage dans des microcanaux<\/strong>, tels que Zymot Multi, visent \u00e0 r\u00e9cup\u00e9rer des spermatozo\u00efdes pr\u00e9sentant une meilleure motilit\u00e9, une meilleure morphologie et une fragmentation de l’ADN moindre, gr\u00e2ce \u00e0 un processus plus physiologique que les m\u00e9thodes conventionnelles de pr\u00e9paration du sperme.<\/p>\n

Dans ces dispositifs de derni\u00e8re g\u00e9n\u00e9ration, les spermatozo\u00efdes doivent traverser des microcanaux ou des micropores, ce qui permet de s\u00e9lectionner ceux qui pr\u00e9sentent la meilleure capacit\u00e9 de mouvement et d’\u00e9carter ceux de moindre qualit\u00e9. L’objectif est d’exclure les spermatozo\u00efdes pr\u00e9sentant des niveaux \u00e9lev\u00e9s de fragmentation de l’ADN double brin, une production accrue d’esp\u00e8ces r\u00e9actives de l’oxyg\u00e8ne (ERO), une faible motilit\u00e9 ou une morphologie alt\u00e9r\u00e9e.<\/p>\n

Cependant, ces syst\u00e8mes pr\u00e9sentent des limites dans le cas d’\u00e9chantillons pr\u00e9sentant des concentrations spermatiques tr\u00e8s faibles ou une motilit\u00e9 fortement r\u00e9duite, car leur fonctionnement d\u00e9pend de la capacit\u00e9 des spermatozo\u00efdes \u00e0 se d\u00e9placer activement \u00e0 travers les microcanaux.<\/p>\n
