Clinical characteristics of study population represented by age groups and ovarian response levels.

Age group	<35		35–37		38–40		>40
Response level	Poor	Non-poor	Poor	Non-poor	Poor	Non-poor	Poor	Non-poor
Number of cyclesa	37	98	7	17	5	14	2	9
Number of retrieved oocytes*b	5.8 ± 0.2	16.8 ± 0.5	4.4 ± 0.4	13.9 ± 0.9	2.6 ± 0.3	11.1 ± 1.2	1.5 ± 0.2	9.0 ± 1.6

E2 value on the day of HCG*	1598 ± 161†	2205 ± 122†	1017 ± 176	2222 ± 533	1076 ± 170	1643 ± 355	750 ± 249	1735 ± 608

^*Numerical values are in the form of mean ± SEM.

^aOnly one cycle from each patient was included in the study.

^bThe number of retrieved oocytes is significantly different among the poor and non-poor responder patients within the <35, 35–37 and >40 age groups. The difference between the oocyte numbers was not significant in >40 age group (p = 0.063).

^†Significantly different from each other (p < 0.01).
