Selected Reform Responsa 183
Tel Aviv, the chief Sephardic rabbi of Palestine, in his Mishpetei Uziel, part Il, Even Ha-ezer, section 19. Epstein — because of the danger that the child may some day, out of ignorance, marry one of the forbidden degrees of relationship opposes the use of seed from a stranger, but permits the use of the husband's own seed— if that is the only way the wife can be impregnated by her husband. Ben Zion Uziel says— as do earlier authorities— that the woman is not immoral because of this act and that the child is kasher, but— disagreeing with Beit Shemu-el— he says that the child is not the child of the donor as to inheritance and Halitzah. He adds that the woman thus impregnated(if not married) may not marry until the time of suckling the child is over.
Since he concludes that the child is not the donor’s child, he therefore considers that the donor has sinned in wasting seed. However, inasmuch as he concludes that the woman is not immoral and not forbidden to her husband, he seems to incline toward permitting the procedure at the recommendation of the physician although he hesitates to say so.
