Le sperme est le liquide essentiel \u00e0 la reproduction humaine. Du grec sperma qui signifie la semence, il contient les spermatozo\u00efdes n\u00e9cessaires \u00e0 la f\u00e9condation de l\u2019ovule. Une \u00e9jaculation de deux \u00e0 six millilitres contient plus de quarante millions de spermatozo\u00efdes.<\/em><\/strong><\/p>\n\n\n\n

L\u2019appareil g\u00e9nital masculin chez l’homme, l’appareil g\u00e9nital est \u00e9troitement li\u00e9 \u00e0 l’appareil urinaire. D’abord, il y a les testicules qui ont la forme d’un \u0153uf d’environ quatre centim\u00e8tres, o\u00f9 sont fabriqu\u00e9s les spermatozo\u00efdes et la testost\u00e9rone. En arri\u00e8re des testicules, se trouve l’\u00e9pididyme qui re\u00e7oit les spermatozo\u00efdes. C’est \u00e0 ce niveau que le flagelle (la queue) du spermatozo\u00efde se forme.<\/p>\n\n\n\n

Ensuite, on trouve le canal d\u00e9f\u00e9rent, un conduit tr\u00e8s fin qui relie l’\u00e9pididyme aux canaux \u00e9jaculateurs et qui transporte les spermatozo\u00efdes. A c\u00f4t\u00e9 se trouvent la prostate et les v\u00e9sicules s\u00e9minales, qui participent \u00e0 la production du sperme. Enfin le p\u00e9nis, ou verge, est constitu\u00e9 de l’ur\u00e8tre qui v\u00e9hicule soit l’urine soit le sperme lors de l’\u00e9jaculation. Il y a aussi trois organes \u00e9rectiles, appel\u00e9s corps caverneux et corps spongieux, qui deviennent rigides lors de l’\u00e9rection gr\u00e2ce \u00e0 un afflux de sang.<\/p>\n\n\n\n

Comment est fabriqu\u00e9 le sperme ?<\/p>\n\n\n\n

Il faut pr\u00e8s de 90 jours pour fabriquer le sperme. D\u2019abord dans les testicules, les spermatozo\u00efdes matures remontent le canal d\u00e9f\u00e9rent vers la prostate et les v\u00e9sicules s\u00e9minales pour y \u00eatre stock\u00e9s. Au moment de l\u2019\u00e9jaculation, les spermatozo\u00efdes se m\u00ealent aux s\u00e9cr\u00e9tions s\u00e9minales et celles de la prostate pour former le sperme.
Le parcours du sperme
La fonction du sperme est de transporter le spermatozo\u00efde jusqu’\u00e0 l’ovule pour le f\u00e9conder.<\/p>\n\n\n\n

D\u00e8s l’\u00e9jaculation, le sperme p\u00e9n\u00e8tre en quelques secondes dans le vagin. L\u00e0, les spermatozo\u00efdes ne peuvent survivre que quelques heures dans ce milieu tr\u00e8s acide. Ensuite, ils remontent vers le col de l’ut\u00e9rus. Apr\u00e8s, tout d\u00e9pend du stade d’ovulation de la femme. Si l’ovule est pr\u00eat \u00e0 \u00eatre f\u00e9cond\u00e9, un spermatozo\u00efde vaillant peut le f\u00e9conder en quelques minutes. L’\u0153uf peut alors se former et cr\u00e9er l’embryon.<\/p>\n\n\n\n

Sinon, un certain nombre de spermatozo\u00efdes stagnent \u00e0 l’entr\u00e9e du col dans la glaire cervicale, o\u00f9 ils peuvent y attendre plusieurs jours avant de f\u00e9conder l’ovule (jusqu’\u00e0 72 heures). A ce niveau, ils en profitent pour continuer leur maturation.<\/p>\n\n\n\n

Un examen du sperme : le spermogramme
Un spermogramme permet de v\u00e9rifier la bonne sant\u00e9 des spermatozo\u00efdes.
Un spermogramme permet de v\u00e9rifier la bonne sant\u00e9 des spermatozo\u00efdes.
La f\u00e9condation ne fonctionne pas \u00e0 tous les coups, ce qui est normal. Mais si au bout d’un an et demi ou deux ans, il n’y a toujours pas de r\u00e9sultat, il y a sans doute un probl\u00e8me.<\/p>\n\n\n\n

Le sperme de l’homme peut ne pas \u00eatre de bonne qualit\u00e9. Il peut y avoir une “asth\u00e9nozoospermie”, si les spermatozo\u00efdes ne sont pas assez mobiles ; une “oligozoospermie”, s’ils ne sont pas assez nombreux, ou encore une azoospermie, s’ils sont totalement absents. De nombreux facteurs peuvent influencer sur la qualit\u00e9 du sperme et des spermatozo\u00efdes. C’est le cas du stress, de la fatigue et m\u00eame de la pollution.<\/p>\n\n\n\n

Pour d\u00e9pister une anomalie, l’homme doit faire un spermogramme. Si l’anomalie du sperme est alors affirm\u00e9e, on propose diff\u00e9rents moyens de procr\u00e9ation m\u00e9dicalement assist\u00e9e : recours \u00e0 un donneur de sperme, ins\u00e9mination artificielle, f\u00e9condation in vitro\u2026<\/p>\n\n\n\n
