Research conducted by the University of Colorado Skaggs School of Pharmacy and Pharmaceutical Sciences provides evidence to support expansion of insurance plan coverage of noninvasive prenatal testing (NIPT), a simple maternal blood draw which screens for fetal chromosomal disorders including trisomy 13 (Patau syndrome), trisomy 18 (Edwards syndrome), and trisomy 21 (Down syndrome), to women under the age of 35.

A new, Yale-led study examines shifts in fertility behaviors among Generation X women in the United States -- those born between 1965-1982 -- compared to their Baby Boomer counterparts, and explores whether the fertility of college-educated women is increasing more quickly across cohorts in Generation X than the fertility of their less educated counterparts.
