[Avodah] Peru uRvu and IVF

[Micha Berger via Avodah]

BH I was recently mesayeim AhS YD, and started EhE. In the Rashi-script
postscript to 1:18, RYME writes:
    And know, that there is someone who explored in [the case of] the
    woman who got pregnant in the baths, if the father fulfilled piryah
    verivyah. However, since this is not shekhiach at all, there is no
    [motive] to go at length about this.

However, nowadays, a halachically similar case *is* common -- IVF.
There is one possibly significant difference; IVF involves intent.
The man who reproduced via a bathhouse likely wasn't planning on doing so.

Tir'u baTov!
