I would say that from a cause perspective, as far as pelvic pain, if you look at pelvic inflammatory disease, it's related really to sexual activity. Number of sexual partners, onset of sexual activity, because usually that's related to one of three potential vaginal infections.
If you look at painful periods, or dysmenorrhea, a lot of times you see that in our younger patients. And you can have primary dysmenorrhea, which is usually less than 20 years of age. And there's usually no etiology for that. There's not really a cause for that. And then over the 20-year age category, you can see secondary dysmenorrhea, which usually has a cause. And that could be related to, like, cervical stenosis, endometriosis, adenomyosis, pelvic congestion syndrome. Those all can be related to secondary dysmenorrhea.
The endometriosis in general, that is related to the implantation of either the endometrial stroma or glands outside of the endometrium. And that can happen anywhere in the body.
