A recently published study sheds light on the approximately 50 percent of unexplained pregnancy losses in the United States. The researchers say the discovery could inform pregnancy care and help women understand the reasons behind their losses, aiding their healing process.
Of the approximately 5 million pregnancies in the United States annually 1 million end in miscarriage and more than 20,000 end in stillbirth. A miscarriage is defined as less than 20 weeks gestation and a stillbirth at or beyond 20 weeks. A full-term pregnancy is considered 40 weeks.
