feminist science; the sperm and the egg st

Unfortunately I can't back this up with references at the moment, but
I have heard that the female has some sort of control over the sperm
which attempt to fertilize the egg.  One method has to do with making
the overall internal environment more or less hospitable to sperm.
Another had something to do with some type of analysis of the sperm done
by the egg.  Yet another has to do with spontaneous aborting of
embryos in cases of genetic abnormalities, or, in some species, in cases
where the female is in a stressful environment in which she is less likely
to be able to successfully raise young.  Females can also choose not to
nurture offspring once they give birth;  in mammals often takes more
energy than the pregnancy.  Red deer does in harsh environments may
selectively abandon male offspring as those offspring are only likely
to be reproductively successful if they are able to become particularly
large (this is a possible explanation for their behavior.)
   If you'd like me to try and track down sources for any of these
vague recollections, let me know...
