Unfortunately we can't see the entire image of your transparency map, so we really can't determine if there is actually pubic hair painted into it. 
Firstly, check your texture map for the model and make certain that pubic hair is clearly present.
Secondly, if pubic area is present, create an image_map of your body texture under PubicHair in the material room and plug that into the Diffuse_Color.  Change the Diffuse-Color to white.
Render and see if that makes a difference.
