Medical science: pregnancy without a vagina, after stabbing?

[Icedragon]

As I am in medical science, I'd love to share an old weird medical story that a colleague pointed out to me: 

 

A 15-year old girl without external female genitalia has been found 9 months-pregnant after she has been to the same hospital due to a knife fight, 9 months before. Doctors can only guess how she might have gotten pregnant. 

Read the story and find the PDF of this publication here http://img2.timg.co.il/communafiles/21227065.pdf

 

Why was she involved in the knife fight and why is that relevant?

 

Just before she was stabbed in the abdomen
shc had practised fellatio with her new boyfriend
and was caught in the act by her former lover.
The fight with knives ensued.

 

 

Explanation:

 

A plausible explanation for this pregnancy is
that spermatozoa gained access to the reproductive
organs via the injured gastrointestinal tract.
It is known that spermatozoa do not survive long
in an environment with a low pH (Jeffcoate
1975), but it is also known that saliva has a high
pH and that a starved person does not produce
acid under normal circumstances (Bernards &
Bouman 1976).
It is likely’that the patient became pregnant
with her first or nearly first ovulation otherwise
one would expect that inspissated blood in the
uterus and salpinges would have made fertilization
difficult. The fact that the son resembled the
father excludes an even more miraculous
conception.
