Sperm with damaged DNA may cause some repeat miscarriages
Semen abnormalities suggest a dad’s health needs to be considered in these pregnancy losses
NEW ORLEANS — For couples who have suffered repeated miscarriages, it may be useful to scrutinize the man’s reproductive health as closely as the woman’s. Some miscarriages may be linked to abnormalities in semen, a study finds.
Researchers analyzed semen from 49 men whose partners had lost three or more consecutive pregnancies before the 20-week mark. The men had sperm with more than twice as much DNA damage and more than four times the amount of certain harmful molecules called reactive oxygen species as samples from healthy men who had been screened for some fertility issues, researchers reported March 24 at the Endocrine Society’s annual meeting.
