Yaso Gel

Alternative Name: PPCM Vaginal Gel

Description: PPCM is a condensation polymer made from mandelic acid and is incorporated into a consumer-pleasing gel (or film or ovule) that is inserted vaginally prior to intercourse. This novel polymer inhibits glycoprotein mediated attachment and fusion of pathogens (HSV, HIV) to target cells. PPCM also inhibits sperm function by causing premature acrosomal loss.
