I didn't read jumping that way, SQ - is she not referring to the fact that women's bodies can react badly to semen (which is by nature unfamiliar to the female body) and this can cause problems with becoming pregnant/getting pregnant?
I admit I base this purely on the ep of the West Wing where Toby's ex-wife has to have treatment because she's struggling to become pregnant as a result of some kind of reaction to his semen, so it just might be less than medically accurate. 
She's correct the homoepathic 'logic' would then be to introduce more semen. Homeopathy is, of course, bollocks (no pun intended), but we knew that.
