Unraveling the biologic and social predictors of infant sex among assisted reproductive technology cycles in the United States

Unraveling the biologic and social predictors of infant sex among assisted reproductive technology cycles in the United States
As assisted reproductive technology (ART) has evolved over the past decades, there has been an increase in the use of ART worldwide, as well as the use of different techniques, including intracytoplasmic sperm injection (ICSI), extended culture, and preimplantation genetic testing (PGT). In this issue of Fertility and Sterility, Narvaez et al. provide an important update on how the use of ART in the United States and the practices specific to ART may be altering the sex ratio (1). She and her coauthors used data from the Centers for Disease Control National Assisted Reproductive Technology Surveillance System (NASS) to assess trends and characteristics associated with a male-biased sex ratio in live-born infants among all ART cycles from 2006 to 2014.
