Vitamine B12 et infertilit\u00e9 inexpliqu\u00e9e : un lien souvent n\u00e9glig\u00e9 Les m\u00e9decins ont tendance \u00e0 prescrire une batterie d’examens aux couples qui rencontrent des difficult\u00e9s \u00e0 concevoir naturellement. Cependant, certains param\u00e8tres essentiels comme la vitamine B12 et l’acide folique sont souvent pas prit en compte. Des \u00e9tudes ont r\u00e9v\u00e9l\u00e9 un lien \u00e9vident entre l’alimentation et la fertilit\u00e9, sugg\u00e9rant que les couples qui tentent de concevoir devraient pr\u00eater attention a plusieurs vitamines dont l’acide folique, \u00e0 la vitamine B12 pour \u00e9viter les carences. Des \u00e9tudes sur la vitamine B12 ont montr\u00e9 que des niveaux faibles peuvent affecter la fertilit\u00e9 chez les hommes et les femmes. Environ 15 % de la population\u00a0 souffre d’une carence en vitamine B12, avec certaines estimations atteignant pr\u00e8s de 40 %. Les niveaux consid\u00e9r\u00e9s comme normaux sont souvent insuffisants\u00a0 des niveaux optimaux pour la fertilit\u00e9. Dans une \u00e9tude sur la FIV men\u00e9e au Massachusetts General Hospital, les femmes ayant eu le plus de grossesse avaient un taux de vitamine B12 s\u00e9rique sup\u00e9rieur \u00e0 700 pg\/ml. Cela indique que le simple dosage de vitamine B12 dans le sang ne suffit pas, car il ne mesure pas la B12 disponible dans nos cellules. On peut avoir un niveau de vitamine B12 normal ou m\u00eame sup\u00e9rieur \u00e0 la normale dans le sang, mais avoir un d\u00e9ficit fonctionnel. L’importance de la vitamine B12 en fertilit\u00e9 Contr\u00f4ler la vitamine B12 en cas d’infertilit\u00e9 inexpliqu\u00e9e est tr\u00e8s important, car les toxines m\u00e9taboliques peuvent affecter la qualit\u00e9 des ovocytes et des spermatozo\u00efdes, augmentant ainsi les chances de fausse couche chez la femme ou provoque des probl\u00e8mes pendant la grossesse. Comment tester sa vitamine B12 ? Pour savoir si notre corps a une quantit\u00e9 suffisante de vitamine B12, nous devons mesurer le taux de la toxine produite par un m\u00e9tabolisme normal qui doit \u00eatre normalement d\u00e9compos\u00e9e \u00e0 l’aide de la B12. Cette toxine s’appelle acide m\u00e9thylmalonique (MMA). Si ce taux est plus \u00e9lev\u00e9 que la norme, cela indique un d\u00e9ficit en vitamine B12. Un autre test similaire est l’homocyst\u00e9ine, il peut refl\u00e9ter une carence en vitamine B12, mais aussi en acide folique ou d’autres maladies. Les causes de d\u00e9ficit de vitamine b12 Il existe plusieurs raisons qui causent le d\u00e9ficit en vitamine b12. Parfois, son absorption sous sa forme active demande plusieurs \u00e9tapes dans notre corps, et ces \u00e9tapes peuvent \u00eatre compromises par plusieurs facteurs tels que les g\u00e8nes MTHFR, des m\u00e9dicaments tels que la metformine, des conditions auto-immunes, la maladie c\u0153liaque ou la maladie de Crohn. Comment corriger le d\u00e9ficit de vitamine B12 ? La forme standard de cette vitamine est la cyanocobalamine, qui n’est pas biologiquement active. Pour les raisons que nous avons cit\u00e9es plus haut, certaines personnes peuvent avoir des difficult\u00e9s \u00e0 la transformer en sa forme active. Nous conseillons de choisir une pr\u00e9natale avec une vitamine avec le nom de hydroxocobalamine ou ad\u00e9nosylcobalamine, et m\u00e9thylcobalamine. Si vous utilisez un dosage plus \u00e9lev\u00e9 que ce dont votre corps a besoin, le reste sera excr\u00e9t\u00e9 et le reste utilis\u00e9 pour reconstituer les r\u00e9serves \u00e0 long terme de B12 dans le foie. Vous pouvez en discuter par la suite avec votre m\u00e9decin pour r\u00e9duire la dose pendant la grossesse.<\/p>","protected":false},"author":1,"featured_media":18046,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[16,17,19,20],"tags":[],"class_list":["post-18044","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-announcements","category-assistance","category-healthcare","category-treatment"],"acf":[],"_links":{"self":[{"href":"https:\/\/oumniafertility.com\/ar\/wp-json\/wp\/v2\/posts\/18044","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/oumniafertility.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/oumniafertility.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/oumniafertility.com\/ar\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/oumniafertility.com\/ar\/wp-json\/wp\/v2\/comments?post=18044"}],"version-history":[{"count":0,"href":"https:\/\/oumniafertility.com\/ar\/wp-json\/wp\/v2\/posts\/18044\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/oumniafertility.com\/ar\/wp-json\/wp\/v2\/media\/18046"}],"wp:attachment":[{"href":"https:\/\/oumniafertility.com\/ar\/wp-json\/wp\/v2\/media?parent=18044"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/oumniafertility.com\/ar\/wp-json\/wp\/v2\/categories?post=18044"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/oumniafertility.com\/ar\/wp-json\/wp\/v2\/tags?post=18044"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
