If a fellow converted (his children remained gentiles) and prior to his conversion he had children - has he fulfilled the Mitzva of Peru U'Revu? (sources)

    I think you need to distinguish between "fulfilling the mitzvah", and subsequently being "exempt from the mitzvah". See the tshuva of Har Tzvi (OH 2:76).

This is part of a discussion on Yevamot 62a. The Shulchan Aruch rules (EH 1:7) that if he and his children converted he has fulfilled his mitzva. The Chelkat Mechokek there (sk 9) quotes the Marharil (#223) that even if his children do not convert he has fulfilled his mitzva.

  • And the Taz there says the opposite, that the children must convert also.

    @Curiouser Just like the Shulchan Aruch himself, and the Rambam and others. I was just quoting one major opinion on both sides. Obviously CYLOR.
