Silicon-based agent

upin mice1

1 study

Silicon-based agent increases sperm count in mice.
“The Si-based agent significantly increased sperm count and velocity (curvilinear and straight-line velocity), reduced the proportion of abnormal seminiferous tubules, and improved testicular histology in aged mice (p < 0.05).”
