Well, this is interesting. In a report released two years ago but which apparently got very little media play, the British Medical Journal reported a survey of pregnancies in the US that indicated 1 in 200 such pregnancies were self-reported as occurring without sexual intercourse; in other words, human parthenogenesis. Now...BIG caveat with this survey: The women reporting are self-reporting; there is no objective way to verify their sexual activity or lack there of. Some of them may not have understood what was meant by sexual activity (for example, what we'd refer to as heavy petting over clothing), others may have been lying either consciously or unconsciously.
Any woman who had child that doesn't match the mother's DNA exactly may be presumed to have had some sort of sexual contact
But...at the very least this report would suggest that the idea of human parthenogenesis, long pooh-poohed by skeptics, may not be beyond the realm of possibility after all.
