Both... orgasms release oxytocin, the hormone which causes contractions, and sperm contains prostaglandins which are fats that cause your cervix to soften/thin.
Yes @mommiesworld it is slightly more successful with both an orgasm AND sperm (to help soften the cervix) but with just masturbation if you have an orgasm it can jump start contractions which will get dilation going once you're far enough along

The orgasm and the sperm! I think the actual act has something to do with it as well.

The cum helps soften the cervix and orgasm helps the contraction
