In 2012, more than 61,000 babies in the U.S. were conceived with the help of IVF, the Society for Assisted Reproductive Technology reported Monday.
That means IVF babies made up 1.5 percent of the 3.9 million births in the U.S, the agency wrote on its website. And it makes 2012 the biggest year for IVF on record: Doctors performed the most procedures and delivered the most IVF babies.
Over the past decade, the number of IVF treatments has been rising. Doctors performed about 113,000 cycles back in 2003. That number jumped by nearly 50 percent to about 165,000 in 2012.
Video: A new instrument, called an Embryoscope, allows fertility doctors to watch the embryo develop after in vitro fertilization. In the video, you can see the embryo go from the first cell division to the blastocyst stage when the cells move to the outside. The time-lapse video takes about five to six days in real time.
