Perceived benefits of ECS
Compared with participants against ECS, a significantly higher proportion of those desired ECS agreed with the statement ‘The test will give you and your partner a better understanding of having a child with a genetic disorder’ (chi-square test, p=1.6E-06) and the statement ‘ECS will be useful for their relatives’ (chi-square test, p=0.027, Table 3). Regarding the statement about perceived reproductive choices as a carrier couple, most participants would take measures to prevent the birth with a severe hereditary disorder, such as by in vitro fertilization (IVF) with embryo selection (19.7%), gamete donation (4.3%) and an examination of the fetus during pregnancy by chorionic villus sampling or amniocentesis (62.7%, Table 2).
