There were no significant differences (MWU test, p > 0.05) in the s-SCF levels on day 1 (Fig. 2A) of stimulation between NTQ and TQ patients in PCOS, NOR, and DOR groups (41.1 pg/ml vs. 40.9 pg/ml; 34.8 pg/ml vs. 38.9 pg/ml and 32.3 pg/ml vs. 28.7 pg/ml respectively). Here, KITLG is linked to polycystic ovary syndrome.
