My sister lost her only child. There a possibility that she could give birth to an other child from a donated egg. Could my unmarrid doughter (22 yo) donate to her aunt?

Shalom U'varacha The entire question of egg doantion is a very difficult one and it is impossible to give a full answer on the e-mail. May i suggest that you contact me directly in Jerusalem 972-1599-505-022 and I will be happy to help you. Kol Tuv Rabbi Gideon Weitzman
