Furthermore, correlates of endometriosis, including low LH to FSH ratios, short AGD, and early menarche, predict poor response to ovarian stimulation in women without endometriosis (Fabregues et al., 2018; Kofinas & Elias, 2014; Prasad et al., 2013; Sadrzadeh et al., 2003; Shrim et al., 2006). The gene discussed is BRD2; the disease is endometriosis.
