oomis1105 -“The mitzvah of pru urvu is incumbent on MEN, not women,”
This is true, but the Halacha is women have to get (are Mechuyav to get) married for other reasons.
“because pregnancy and childbirth are ALWAYS a sakana (hence the making of birchas hagomeil after childbirth), and you cannot force a woman to put her life in jeopardy for the sake of a mitzvah. Obviously the halacha teaches us that skanos nefashos is of prime concern, even when it comes to mitzvos that are clear directives, much less those that are not.”
While this is a nice Shtickle Torah -I’m sure it’s not accurate because we hold there is a Chiyuv to get married -so I doubt this “Sakana” is enough to stop the Chiyuv of getting married for women, but you might say it’s enough to stop the Chiyuv of Pru OOrevu.
Without me doing any research into it – I’d say maybe they aren’t Mechuyav in Pru OOrevu because it’s a Mitzva Shehazman Gromoh. There are times when it’s Ossur to be together.
