A study by university researchers in Bangkok shows that post-vasectomy, the incidence of sperm with chromosomal abnormalities such aneuploidy or diploidy [different numbers of certain chromosomes, or a full double set, respectively] increases dramatically.
Post-vasectomy? Those guys are out of a job anyway, so who cares if they're abnormal, right? Right. Well, it turns out those abnormalities persist after a vasectomy reversal, too.
It hasn't been studied yet, so no one knows whether this increases the risks during pregnancy or for children born after a vasectomy reversal. Still, you might just want to mention it to the family obstetrician all the same.
