In vitro fertilization is becoming increasingly popular in the United States, especially in millennial women, according to a new report by the Society for Assisted Reproductive Technology (SART).

In 2013, 2,000 more babies were born through the use of IVF than in 2012. Approximately 175,000 cycles of the treatment led to more than 63,000 infants being born. The report also notes that more women, especially those under 35, are choosing to transfer a single embryo, rather than multiple embryos—which eliminates the possibility of multiple pregnancies through one IVF cycle.

"The goal of reducing the incidence of multiple pregnancies is extremely important, and patients can see from the data that fewer embryos transferred do not mean a lower chance of pregnancy," said James Toner, M.D., president of SART.

Since fewer women are transferring multiple embryos, twin and triplet birth rates resulting from IVF have noticeably decreased. The report also states that from 2012 to 2013, the number of twins dropped from 12,436 to 12,085, and the number of triplets fell from 411 to 376.

These trends are likely to continue along the same patterns in the coming years—especially with more advanced IVF techniques, like Britain's newly approved "three-parent" IVF technique and the newest stem cell and IVF technology that may lead to same-sex couples having a biological child.
