Denying all contraception, even to married women. Especially married women!
Denying all GYN care, after all you never know when they might be sneaking in an abortion.
It's about power. Knowledge is power; knowing when a woman is menstruating is to know when she is more emotionally vulnerable, physically vulnerable to things like blocking access to bathrooms, etc.
Anybody other than her GYN who wants to know anything about the menses of any woman in my family...
