Isso mostra que não é só velocidade… existe compatibilidade biológica envolvida. 📚 Referências científicas: Pesquisa publica

Do ovulo ao embriao. A fertilização in vitro vista pelo microscópio 🔬 👀 Um casal que realiza a fertilização in vitro quer ter um bebê no colo ao final do tratamento. Mas o processo começa beeeeem antes! Após a coleta de óvulos, esse material é analisado por um embriologista, que separa os óvulos maduros e de melhor qualidade de possíveis detritos, líquidos e outras células. 🐣 Depois, os espermatozóides são captados e inocula-se apenas o material genético dentro do óvulo, que é uma cé
