Pentru a ajunge la această concluzie, oamenii de ştiinţă de la Universiatea din Nanjing, China, au examinat rezultatele a 46 de studii care au comparat cazurile de defecte ale copiilor născuţi prin tehnici de reproducere asistată şi cele ale copiilor născuţi normal.
La cei aproape 124.000 de copii născuţi prin FIV cu ICSI (injectarea intracitoplasmatică a spermatozoizilor), riscul de defecte a fost cu 37% mai mare.
Studiul, apărut în publicaţia „Fertilitate şi sterilitate”, nu precizează motivul pentru care tehnicile de reproducere umană asistată cresc riscul de defecte congenitale (genitale, osoase, digestive sau ale sistemului nervos).
Este posibil ca probabilitatea de apariţie a acestor defecte să fi fost influenţată chiar de cauza infertilităţii.
