Resumen de The Paternal Epigenome Makes Its Mark
For decades, prenatal advice has mainly focused on mothers. Leading up to and during pregnancy, women are told to take folic acid supplements, stop drinking and smoking, avoid high-mercury fish, and maintain healthful weight gain, among other wisdom. That advice is prescribed by physicians and public health experts to promote healthy pregnancies, normal fetal development, and long-term offspring health. A father’s behavior can also influence the health of a pregnancy, by exposing his partner to secondhand smoke or domestic violence, for example. But there’s a growing belief among scientists that a man’s behaviors and environmental exposures may also shape his descendants’ development and future health before sperm meets egg.
