Recently, they took the DNA from bone marrow and fertilized an egg, but it's not really a technology that's practical for humans currently (lots of health complications and short life span of child). Maybe in the future, though. This one I've more come across as hearsay in the LGBT community, and I couldn't provide links or anything. So although I don't think it's just a wishful rumor, it may be exaggerated in its potential human applications. But I've got my fingers crossed, I'm just not holding my breath.
Something a lot of people do, of course, is to have a close male relative as the sperm donor, that way the child is genetically similar. Something I've thought about as a possibility, if you can get past the weird.
