Table 1 Patient background of each group

Parameter	Control group, n = 11	IOF group, n = 11	POI group, n = 11	P value
Age (yr)	35.8 ± 3.0	37.5 ± 1.7	35.8 ± 2.7	0.195
BMI in kg/m2	20.1 ± 1.9	20.1 ± 2.1	19.4 ± 2.5	0.678
Gravidity as number of times	0.6 ± 0.7	0.4 ± 0.5	0.6 ± 0.9	0.598
Parity as number of times	0.4 ± 0.5	0.2 ± 0.4	0.3 ± 0.5	0.655

Values are expressed as means, with the error bar representing the standard deviation. There were no significant differences among the three groups. BMI: Body mass index; IOF: Incipient ovarian failure; POI: Premature ovarian insufficiency.
