Both birth control and SSRI are prescribed like candy these days, including to adolescents. Women are shutting down their HPTA for decades, when they come off, their ovaries don't come back online most of the time. Women do get shutdown like the men, contrary to internet myth/broscience.
Some testosterone is of adrenal origin, but a lot of it comes from the ovaries. The women with PCOS have high testosterone levels due to high levels of LH overstimulating the ovarian follicles.
It sucks when they guys get put on TRT and they want to fuck like rabbits and their wives/girlfriends have the libido of a hysterectomized nun. Most of the time it's low T, birth control or SSRI use. Women's HRT is done completely wrong by most clinicians, women's hormones are like chess to men's checkers. Much more complex, and clinicians can't even get TRT right, so no surprise there.
