Propylparaben sodium (Propyl parahydroxybenzoate) is an antimicrobial preservative which can be produced naturally by plants and bacteria. Propylparaben sodium is prevalently used in cosmetics, pharmaceuticals, and foods. Propylparaben sodium disrupts antral follicle growth and steroidogenic function by altering the cell-cycle, apoptosis, and steroidogenesis pathways. Propylparaben sodium also decreases sperm number and motile activity in rats.
