It's odd this is getting so downvoted. A lot of projection perhaps? We don't know the answer and there's good research showing cannabinoids in sperm. Why's it so outrageous to suggest that until we know the answer, don't birth a kid with a weed tinted fertilizer?
The answer above is neutral, yours is not "don't birth a kid with a weed tinted fertilizer". There are many things that hypothetically could be bad and we do not have the answer. Which is we normally go by the opposite approach:
What data do we have that indicates, that high sperm is bad?
As far as I know, none.
(A pregnant mother smoking is a whole different story)
