While two separate issues, there is an association between endometriosis and polycystic ovarian syndrome (PCOS) (Holoch et al., 2014; Hager et al., 2019). There isn’t much data on the incidence of endometriosis and PCOS together. One study noted it to occur in about 19.7% (Holoch et al., 2014).
Below you will find a few links and studies on PCOS.
