How a Father's Lifestyle May Be Transmitted Through Sperm RNA to Offspring

Summary

This article from Quanta Magazine challenges the traditional view that sperm only deliver DNA to an egg. It presents nearly two decades of research showing that sperm also carry RNA molecules that can be influenced by a father's lifestyle choices — such as diet, exercise, stress, and nicotine use — and may transfer those traits to offspring. The piece explores the emerging science of paternal epigenetic inheritance through sperm RNA, detailing how these small non-coding RNAs can package information about the father's environment and potentially shape the development and health of his children.
