The following details answer the question wonderfully. To sum it up, yes, it is safe to swallow semen, if you know for sure it doesn't contain STDs.
1. Pregnant? Semen and sperm go down into your stomach, where they are digested with all your other food. There is no passage connecting your stomach to your ovaries. You can not get pregnant from swallowing sperm. If the donor has no STDs, it's perfectly safe. If you plan to have a baby with the man in question, it can also lower the chance of miscarriage. By having your body recognize the antigens in the man's semen you can reduce the possibility of an inappropriate immune response.
2. Fattening? Semen is full of protein, minerals (zinc Calcium), some fructose sugars and other nutrients. It has few calories, and is perfectly safe to swallow if it has no disease germs.
3. Your own? You can safely swallow your own semen. You can't catch a disease from yourself, only from other people. (Although you can spread your own germs to new, and perhaps more vulnerable, places on your body!)
4. Other people have diseases! You can catch gonorrhea, syphilis, herpes, chlamydia and genital warts from another person. All of these (except herpes and genital warts) can be cured with antibiotics, but it is annoying and inconvenient and unhealthy to get them.
HIV, the virus which can cause AIDS if untreated, is a far more serious thing. People die from AIDS. There is no cure, though daily medication for years can prevent it developing into anything dangerous. HIV virus is contained in body fluids, like semen, but it has to get into your blood through your bleeding gums or damaged teeth. If your mouth is strong and your gums are firm, then you can swallow the HIV virus without any trouble.
All these diseases (except HIV) are passed on through contact with sores or lesions, as well as in pre-ejaculate (pre-cum) and semen, so you may be exposed to them before your partner ejaculates. The safest thing to do with semen in your mouth is to swallow it. The enzymes and acids in your stomach will quickly destroy any viruses and bacteria. Or spit it out, and use a mouthwash to remove any lingering. Don't brush your teeth before or after oral sex. The brushing can cause slight bleeding of your gums leaving them open to infection from HIV.
There is only a tiny amount of sperm in semen. I think you wanted to ask "it is safe to swallow semen?". Of course it is safe. People have been doing that forever, and I think it is safe to say it never hurt anyone.
Yes, women can swallow semen. So can men. If the contributor of the semen is healthy, it will not hurt you to swallow semen.

If they are healthy and you are healthy; there would be on danger from the interaction.
There's no problem if you swallow ones semen or your own semen if you have diabetes Unless you mix it with sugar or something sweet can be attributed to high sugar level
Women don't produce semen. If it's producing semen, it's not a woman.

Im guessing you mean Catching HIV, not having HIV. And yes, if you swallow the semen of someone who is HIV positive, you can catch it from that.

No. There is no link between the stomach and the uterus.
