However, these studies had limitations such as being presented as a case report (13), describing a single case of tissue cryopreservation (15), involving only a few patients (16–18), involving inconsistent AMH measurement methods (19), grouping endometriosis patients as non-oncologic patients (18, 20), or involving a comparison between surgical and nonsurgical groups among patients with endometrioma without the inclusion of healthy controls (17). The gene discussed is AMH; the disease is endometriosis.
