I understand the concern about AIDS, but what people need to realize is that was only a ten year epidemic that lasted from 1981 to about 1991. It was not and is not a permanent aspect of homosexuality, but rather a specific period of time with a clear beginning and end. Besides, if they're really that concerned, I'm pretty sure doctors could do a blood test to determine whether or not there were any HIV viruses present in the blood stream and/or organs. Sexually transmitted diseases can only be contracted by having sex with someone else who has the disease. If two people who are both totally clean have sex with each other, then it's impossible for either one of them to contract a disease as a result, even if they're of the same sex. If the two men in this case were involved in a purely monogamous relationship with each other, then the risk of HIV is virtually zero.
