Women need that extra boost of kedusha that they are born with. They wouldn’t be able to survive spiritually with out it. Think about if a man would be able to make it with out going to minyan for 25 yrs in their life. A woman generaly doesn’t go to shul when she has children at home. Even on the yomim no’raim she is lucky if she goes for a few mins. A woman has built in kochos that instill in her the kedusha that she doesn’t get from the sources men do.
