Almost all types of hormonal birth control switch off ovarian function and, therefore, switch off the ovarian hormones estradiol, testosterone, and progesterone. Here’s a bit more about each method.

How Science Got It Wrong About Progesterone
Progesterone has been both ignored and mistakenly blamed for side effects it does not cause. How did that happen?
For one thing, progesterone was discovered shortly after estrogen. Thus, missing out on the tidy hormone dichotomy of “testosterone for men and estrogen for women,” pointed out endocrinology professor Jerilynn Prior. Also, progesterone could not (at first) be made into a medication that could be absorbed orally.
The Secret Powers of Ovulation (It’s Not Just to Make a Baby)
Ovarian hormones estrogen and progesterone are beneficial for health. That means natural ovulatory menstrual cycles are beneficial for health because ovulation is how women make hormones.
Does that surprise you? Men make testosterone every day, so you might think women do something similar, but we don’t. Instead, women make hormones as a surge of estradiol leading up to ovulation and an even bigger surge of progesterone after ovulation.
Do Women Need Periods?
With the 2019 news that women don’t need pill bleeds came the assurance that “women don’t need periods.” But is that accurate?
It’s true that women don’t need monthly pill withdrawal bleeds because they’re not periods, but women do need (or at least benefit from) monthly natural menstrual cycles because natural ovulatory cycles are how women make the hormones estradiol and progesterone.
