Sperm is more costly than commonly thought. There's a large literature,
largely based on fish studies, showing differential sperm release under
different mating conditions because males are often sperm limited. I'll
agree with Peter's qualms about a study that doesn't show numbers but only
the statistical test(s) run by the authors. But to me it's entirely
plausible that there is some discrimination in sperm release between
different classes of females.

I've never kept Amazon mollies, but they've always fascinated me (or am I
merely sex obsessed...).
