Silver Nanoparticles Stop Sperm Stem Cell Growth

A new study has identified exactly how silver nanoparticles cause male reproductive cells to stop growing.

Minute materials used in a number of consumer products such as antimicrobial agents can interrupt important cell signaling within male reproductive sperm cells, causing them to stop growing, according to a new study that builds on previous work by the same research group.

In prior studies, the scientists reported how smaller-sized silver nanoparticles – in the 10 – 25 nanometer range – decreased the growth of male stem cells when they were exposed at concentrations greater than 10 micrograms per milliliter (ug/ml).

The new study is the first to identify how the silver nanoparticles stop the sperm stem cells from growing. The biggest effects were caused by the smallest-sized nanoparticles tested.
