L\u2019infertilit\u00e9 masculine est responsable d\u2019environ la moiti\u00e9 des cas d\u2019infertilit\u00e9 dont on connait l\u2019origine dans un couple, donc si vous rencontrez des difficult\u00e9s \u00e0 concevoir un enfant, il est important de prendre en compte la fertilit\u00e9 des deux parties quand vous essaierez de diagnostiquer et de faire face aux probl\u00e8mes potentiels. Contrairement aux femmes, les hommes peuvent rester fertiles toute leur vie. La production de sperme diminue bien avec l\u2019\u00e2ge, mais ils peuvent quand m\u00eame continuer d\u2019en produire jusqu\u2019\u00e0 un avanc\u00e9.<\/p>\n

De nombreuses choses peuvent contribuer \u00e0 l\u2019infertilit\u00e9 masculine. Pour \u00eatre fertile, l\u2019hypothalamus, l\u2019hypophyse (chacun s\u00e9cr\u00e9tant des hormones et se trouvant dans le cerveau) et les testicules de l\u2019homme doivent fonctionner correctement. La majorit\u00e9 des cas d\u2019infertilit\u00e9 (entre 30 et 40%) provient de probl\u00e8mes au niveau des testicules tels que des veines dilat\u00e9es (varicoc\u00e8les), des voies g\u00e9nitales obstru\u00e9es, ou des dommages subis au niveau des structures productrices de sperme des testicules. De ces troubles m\u00e9dicaux, entre 15 et 25% sont g\u00e9n\u00e9tiques (ce qui ne veut pas forc\u00e9ment dire qu\u2019ils sont h\u00e9r\u00e9ditaires).<\/p>\n

Entre 10 et 20% des cas d\u2019infertilit\u00e9 masculine proviennent d\u2019une forme ou d\u2019une autre d\u2019obstruction du sperme<\/a>, ce qui peut \u00eatre le r\u00e9sultat d\u2019une infection ant\u00e9rieure. Les troubles au niveau de l\u2019hypothalamus et de l\u2019hypophyse repr\u00e9sentent une petite portion (1 \u00e0 2%) des cas d\u2019infertilit\u00e9 masculine.<\/p>\n

Malheureusement, cela laisse entre 40 et 50% de cas d\u2019infertilit\u00e9 dont on ne peut discerner les origines. On recommandera sans doute aux couples qui d\u00e9cident de r\u00e9aliser des tests de fertilit\u00e9 de faire une analyse de semence. Cette analyse fournit des informations sur la densit\u00e9 et la motilit\u00e9 du sperme et la forme des spermatozo\u00efdes, ainsi que le volume et la concentration de la semence.<\/p>\n

Dans de nombreux cas, les m\u00e9decins pratiqueront une s\u00e9rie d\u2019analyses de sperme dans le temps pour s\u2019assurer d\u2019avoir des r\u00e9sultats pr\u00e9cis. Il est parfois impossible d\u2019identifier une origine sp\u00e9cifique de l\u2019infertilit\u00e9 chez l\u2019homme m\u00eame apr\u00e8s l\u2019analyse de sperme. Il est possible que l\u2019analyse de semence r\u00e9v\u00e8le une faible motilit\u00e9 ou une faible densit\u00e9 mais ne suffise pas au m\u00e9decin pour discerner l\u2019origine de ces troubles. Dans ce genre de cas, le m\u00e9decin pourra recommander soit des analyses plus approfondies, notamment une \u00e9chographie du scrotum, des tests hormonaux, soit des tests sp\u00e9ciaux sur le bon fonctionnement du sperme. M\u00eame si un m\u00e9decin est incapable de d\u00e9terminer l\u2019origine sp\u00e9cifique de l\u2019infertilit\u00e9 \u00e0 ce stade, il pourrait quand m\u00eame \u00eatre en mesure de recommander certains traitements ou proc\u00e9dures pouvant mener \u00e0 la conception.<\/p>\n

Il existe de nombreuses ressources relatives \u00e0 l\u2019infertilit\u00e9 masculine<\/a>, mais nous vous conseillons de commencer chez votre m\u00e9decin. Il\/elle saura vous recommander des sp\u00e9cialistes form\u00e9s pour r\u00e9pondre \u00e0 ces questions et \u00e9valuer les options aff\u00e9rentes \u00e0 l\u2019infertilit\u00e9 masculine. Un sp\u00e9cialiste de la fertilit\u00e9 peut vous parler de vos options si vous essayez de concevoir, et prendre en consid\u00e9ration des ennuis de sant\u00e9 pass\u00e9s et\/ou pr\u00e9sents chez le partenaire (et la partenaire, si besoin).<\/p>\n","protected":false},"excerpt":{"rendered":"
