Gestação em idade avançada e aconselhamento genético: um estudo em torno das concepções de risco.

Scientific innovations around the study of human chromosomes, which emerged after the mid 20th century, consolidated the incorporation of genetics in prenatal diagnosis. The link between maternal age and genetic syndromes, proposed by biomedical researchers, produced resolutions about risks to pregnant women of a certain age. The article presents biomedicine concepts for advanced maternal age classified as a risk pregnancy. The review of Brazilian and foreign medical manuals in obstetrics and genetics showed different conceptions of risk concerning the reproductive age factor. Maternal age is an aspect in obstetrics related to the risk of diseases. For genetic expertise, advanced maternal age is not a central factor of risk for reproduction. The research found that the classification of an ideal maternal age for pregnancy is relative and susceptible to changes according to the socio-historical context of each society.
