Avant que les risques li\u00e9s aux transferts de plusieurs embryons ne soient pleinement compris, de nombreux sp\u00e9cialistes de la fertilit\u00e9 pensaient que le transfert de plus d\u2019un embryon lors d\u2019une FIV augmentait les chances d\u2019obtenir une grossesse r\u00e9ussie et une naissance vivante.<\/p>

Cependant, des preuves de plus en plus nombreuses ont montr\u00e9 que le transfert de plusieurs embryons augmente consid\u00e9rablement le risque de complications, tant pour la m\u00e8re que pour les b\u00e9b\u00e9s, et il a \u00e9t\u00e9 reconnu que ces risques l\u2019emportaient souvent sur les avantages potentiels.<\/p>

Une importante nouvelle \u00e9tude*, l\u2019une des plus vastes de ce type, a d\u00e9sormais montr\u00e9 que les techniques contemporaines peuvent am\u00e9liorer les chances d\u2019avoir un b\u00e9b\u00e9 tout en r\u00e9duisant significativement la probabilit\u00e9 de grossesses g\u00e9mellaires et triples.<\/p>

Les chercheurs ont analys\u00e9 les r\u00e9sultats de plus de 18\u202f000 femmes effectuant leur premier cycle de FIV entre 2012 et 2021, dans sept cliniques diff\u00e9rentes \u00e0 travers l\u2019Australie.<\/p>

Ils ont constat\u00e9 un taux cumulatif de naissances vivantes de 68,2 % sur trois cycles de traitement, avec plus de 95 % des transferts r\u00e9alis\u00e9s en transfert d\u2019un seul embryon, et un taux de naissances multiples inf\u00e9rieur \u00e0 3 %. \u00c0 titre de comparaison, des \u00e9tudes historiques avaient montr\u00e9 un taux de naissances vivantes allant jusqu\u2019\u00e0 59 %, avec des taux de grossesses multiples sup\u00e9rieurs \u00e0 20 %. <\/p>

L\u2019\u00e9tude a attribu\u00e9 ces \u00e9volutions \u00e0 la mise en \u0153uvre de pratiques cliniques modernes telles que la culture au stade blastocyste (d\u00e9veloppement des embryons en laboratoire jusqu\u2019au jour 5\/6 apr\u00e8s la f\u00e9condation, plut\u00f4t que le jour 2\/3 traditionnel), la vitrification embryonnaire (cong\u00e9lation rapide des embryons, qui augmente leurs chances de survivre \u00e0 la cong\u00e9lation\/d\u00e9cong\u00e9lation) et les cycles \u00ab freeze-all \u00bb (embryons transf\u00e9r\u00e9s un par un apr\u00e8s le cycle initial de stimulation).<\/p>

Commentant ces r\u00e9sultats, le Dr Luciano Nardo, consultant en m\u00e9decine de la reproduction et infertilit\u00e9 chez NOW-fertility, a conclu : \u00ab Ces r\u00e9sultats soulignent la n\u00e9cessit\u00e9 de continuer \u00e0 \u00e9largir l\u2019acc\u00e8s au transfert d\u2019un seul embryon dans le monde, en soutenant des soins de fertilit\u00e9 plus s\u00fbrs et plus efficaces pour tous. \u00bb<\/p><\/blockquote>
