Drop-In Twin Birth Rates

After three decades of will increase, the US birth rate for twins has dropped. The regular rise had been attributable mainly to the use of in vitro fertilization. Now, the 4% fall from the year 2014 to 2018 might be due to new reproductive technology that makes single births more probably, a statement from the Centers for Disease Control and Prevention states. Multiple births can be risky for the mother and babies, according to news reports, so researchers see the decline as optimistic. “In the media, there are sometimes tales about adorable twins,” a CDC researcher states. “These stories don’t give attention to the risk.” The risks for the mother include diabetes, hypertension, hemorrhaging, and postpartum depression. There’s additionally a greater danger of death for both mothers and babies, and twins are more likely to be born sooner and smaller.

 The variety of twin births more than doubled from 68,339 in the 1980s to a peak of 138,961 in 2007, then fell to 123,536 in 2018, the National Center for Health Statistics discovered. Until recently, many fertility doctors transferred multiple embryos throughout in vitro fertilization in hopes that at least one would be successful. Often, that led to multiple births. Now, per the Washington Post, many doctors transfer one embryo at a time. Advances in embryo freezing and genetic testing have helped make single transfers successful more usually. “I’m elated,” a Texas specialist mentioned. “What takes away from this is that we’re working hard to ensure that families have the healthiest pregnancies possible.”
