Comparison of the pregnancy and fertilization in the different groups as an indication of infertility. The (A) fertilization rate and (B) pregnancy rate in each group were counted. The infertile individuals were characterized into six groups: other female factors (O, female factor without endometriosis and PCOS), endometriosis (E), ovarian endometrioma (EC), endometriosis without ovarian endometrioma (ENC), male factor (M), and polycystic ovary syndrome (P). The fertilization rate and pregnancy outcome values were significantly lower in the EC group than they were in the other groups. The p-value for each group versus the group with other female factors was determined by an unpaired t-test.
