to the rabbiofberlin. Your point asside, It is an injustice to say he allowed artificial insemination. He did not, someone came with a shayla, after his wife had already been aftificially inseminated with donor sperm, if his wife was ossur and if the son was a mamzer. R’ Moshe paskined no on both counts, but he was never “mattir” the artificial insemination from a donor.
(I mention this not to debate you, but because some fertility clinics put of a copy of the teshuva to persuade people into following the above mentioned woman’s lead.)
