Abstract
Griseofulvin is known to interfere with chromosome segregation by binding to microtubule-associated proteins. Studies in mouse germ cells have demonstrated that griseofulvin can induce aneuploidy (numerical chromosome abnormalities) at therapeutic concentrations. The aim of this study was to determine if chronic griseofulvin treatment led to an increased frequency of sperm chromosome abnormalities in one male subject. We analyzed 290 full sperm karyotypes using the human sperm-hamster oocyte fusion system. The frequency of X- and Y-bearing sperm was equal. There was no increase in the frequency of numerical (1.7%) or structural (9.3%) abnormalities in the subject compared to unexposed controls. Although reassuring, this is the first report on this subject and future studies are needed to assess the risk of griseofulvin.
