Hmmm, maybe that came out incorrectly!
At a recent Skeptics braai (barbecue for you Americans) the Skeptic Detective mentioned a fascinating story about a girl with no vagina who became pregnant after oral sex and a knife fight – perhaps it is better that you read the article and get the details:
Sometimes you just cannot make this stuff up!
In a crude sense, there was an analogue of the basic sexual act – sufficient forces were applied in an effective and efficient manner to sperm, said sperm was able to reach the surface of the egg, the egg was receptive and conception took place – kinda like going the long way round for Chinese food, as long as the end result is achieved, the path to acquire target is largely irrelevant.
That said, I would be fascinated to learn the exact route possible from the peritoneal cavity to the uterus – the uterus seems to be proximal to the cavity but it is not clear if it is within said cavity – I do not have sufficient anatomical knowledge to definitively answer this…
It may be impossible to use the usual internal human anatomy to propose a possible path seeing as the patient had some degree of unusual internal anatomy (aplastic distal vagina) so we do not know what other organ systems would be arranged in novel ways.
Comment 145 on the site adds awesome possible alternatives – the idea that she might have at least one functioning, undescended testicle being my favourite.
Bizarre anatomy, my new favourite tag.
