ATLANTA--(BUSINESS WIRE)--A recent study, documented in a December 2017 edition of Science News, uncovered how stress changes the genetic payload of a male’s sperm. Although the discovery that stress could be passed from one generation to the next through the father’s sperm had previously been documented, this is the first time that researchers have been able to witness the way in which stress is transferred.
This study, which used mice, focused on the caput epididymis, the location within the male reproductive system where sperm cells mature. As test subjects were presented with alarming stimuli for extended periods of time, their sperm showed a consistently altered genetic payload in their RNA, producing offspring with an overabundance of the stress hormone corticosterone.
