Assisted reproductive technology

The number of couples treated has fallen slightly in recent years. At the same time, the percentage of women who gave birth following treatment has continually increased. The data concern in vitro fertilisation methods (IVF), in which fertilisation occurs outside of the human body. In Switzerland, one in forty children is born as a result of medically assisted reproductive technology with in vitro methods.

The percentage of multiple births following in vitro treatments was 16% in 2016. In 2019 the percentage of multiple births had fallen to 6% of births following in vitro treatments. As multiple births are often associated with complications during pregnancy and birth, this is an important development for neonatal health.
