Colloidal silver nanoparticles induced detached sperm heads in a dog
Abstract
We describe a sperm abnormality (detached heads) in a dog treated with a topical (spray) medication containing colloidal silver nanoparticles (AgNP). However, sperm morphology and fertility recovered 5 months after withdrawal of treatment. To our knowledge, this is the first report of an association between AgNPs and abnormal canine sperm.
