What sort of contaminants would you suggest be tested for in semen? There
may be some value in doing it, but it would not be a substitute for testing
breastmilk. Substances such as PCBs, DDT (and its metabolites), and an
array of persistant organic pollutants are lipophilic substances, meaning
that they are "fat-loving" and will not be found in any great quantity in
non-fatty tissues and fluids. If I recall correctly, semen does not have a
high fat content; the fluid acts as a buffer and energy source (sugars) for
the sperm. Consequently, several of the especially worrisome chemicals
aren't going to be found in it.
At any rate, I agree about the concern breastmilk testing creates about
breastmilk safety and I know that's a huge concern among the researchers.
