Une femme nait typiquement avec un \u00e0 deux millions d\u2019ovules, c’est sa r\u00e9serve ovarienne. Cela semble \u00e9norme, mais curieusement, les f\u0153tus f\u00e9minins ont beaucoup plus d\u2019ovules lorsqu\u2019ils se trouvent encore dans le ventre de la m\u00e8re\u00a0; cela va parfois jusqu\u2019\u00e0 6 ou 7 millions.<\/p>\n

Quand les ovules sont encore immatures, on peut parler d\u2019ovocytes. Quand la jeune fille devient pub\u00e8re, il ne lui reste qu\u2019une fraction du nombre initial d\u2019ovules\u00a0: en g\u00e9n\u00e9ral environ 300\u00a0000. Sur la dur\u00e9e de vie reproductive, une femme n\u2019ovule que plus ou moins 500 fois. Le reste des ovules s\u2019autod\u00e9truisent \u00e0 la m\u00e9nopause. Quand il ne lui reste que 1000 ovules (ou moins) dans les ovaires, on consid\u00e8re que la femme est m\u00e9nopaus\u00e9e.<\/p>\n

Avant la m\u00e9nopause, une femme perd en moyenne 1000 ovules tous les mois\u00a0; la destruction des ovules est un \u00e9l\u00e9ment naturel du syst\u00e8me reproducteur f\u00e9minin.<\/p>\n

La quantit\u00e9 d\u2019ovules est tout aussi importante que la qualit\u00e9 de ceux-ci. En vieillissant, les ovules perdent en qualit\u00e9, et le risque d\u2019anomalies chromosomiques au niveau des ovules augmente. Quand la qualit\u00e9 des ovules diminue, la femme peut \u00e9prouver des complications dans ses tentatives de concevoir. L\u2019ovule de pi\u00e8tre qualit\u00e9 pourrait ne pas \u00eatre f\u00e9cond\u00e9, et m\u00eame s\u2019il l\u2019est, il pourrait ne pas se d\u00e9velopper suffisamment pour s\u2019implanter<\/a> dans l\u2019ut\u00e9rus. L\u00e0 encore, m\u00eame s\u2019il est f\u00e9cond\u00e9 et s\u2019implante dans l\u2019ut\u00e9rus, il peut ne pas \u00eatre en assez bonne sant\u00e9 pour un d\u00e9veloppement f\u0153tal ad\u00e9quat. Ainsi, la quantit\u00e9 d\u2019ovules n\u2019est pas le seul facteur \u00e0 prendre en consid\u00e9ration quand on essaie de concevoir\u00a0: leur qualit\u00e9 est tout aussi importante.<\/p>\n

Chaque individu est unique, et quand bien m\u00eame l\u2019\u00e2ge<\/a> est un facteur d\u00e9terminant de la fertilit\u00e9 chez la femme, il est possible chez certains sujets de 30 ans, voire moins, de rencontrer des soucis au niveau aussi bien de la quantit\u00e9 que de la qualit\u00e9 de leurs ovules, alors que des femmes de 43 ans peuvent tout \u00e0 fait \u00eatre encore assez f\u00e9condes pour r\u00e9ussir \u00e0 concevoir.<\/p>\n","protected":false},"excerpt":{"rendered":"
