Not much...I remember someone asking this question in Sex Ed class, and the teacher's response was that it happens all the time during oral sex and that there's no health problem associated with it UNLESS the semen comes from someone with an STD.
when you swallow sperm it doesn't happen nothing, but if u eat it in a regular basis its good for the skin, because sperm is rich in a protein called D21 which make your spores stretch making your skin smoother.
Semen is very high in protein. Biologically speaking, this is the only advantage to this activity. However, semen is a body fluid and can transmit parasites, bacteria, and all sorts of STD's such as HIV, herpes, syphillis, etc.
This activity should only be practiced in a monogamous relationship after both parties have had a physical exam for STD's.
But if your man is healthy, swallowing semen can be a great addition to your sex life.
Men have the basic need to be "accepted" by you. His semen is him, at least it's from him. He feels hurt if you "reject" it. It's like you are spitting out him.
It brings you closer to him. He feels more protective of you and respects your doing it for him. Also he knows he is with you because he is in you. It's good for him that you do it.
And swallowing has some great health benefits for you.
Women who want to get pregnant prepare their bodies by swallowing their man's sperm. This attunes her immune system to let his sperm though to her egg.
Women who are pregnant should be swallowing three time per week (Semen Therapy) to prevent a dangerous condition called Pre-eclampsia.

It is the immune system rejecting the fetus for it's unknown DNA, unless she has been swallowing to prepare her body.
