Rabbi Eliezer Hisma in Pirkei Avot 3:18 says the laws many people overlook are the critical laws to learn, especially family purity. Rabbi Yaron Reuven says Family Purity is the foundation in building a Jewish home, and a holy Jewish family. And both Jewish men and women must learn the laws of Taharat HaMishpacha.
