Comparison of basic characteristics between the spontaneously falling E2 group and the drug dosage reduction group.
| Variables | Spontaneously reduction (n = 63) | Dose-adjusted reduction (n = 57) | P value |
|---|---|---|---|
| Age (years) | 30.67 ± 4.18 | 30.02 ± 4.09 | 0.392 |
| BMI (kg/m2) | 23.04 ± 3.62 | 20.93 ± 2.92 | 0.001 |
| AFC (n) | 22.42 ± 10.35 | 21.06 ± 9.59 | 0.497 |
| Protocol | |||
| Long % (n) | 12.70% (8/63) | 1.75% (1/57) | 0.034 |
| IPM% (n) | 7.94% (5/63) | 15.79% (9/57) | 0.181 |
| IPF% (n) | 79.36 (50/63) | 82.46% (47/57) | 0.667 |
BMI, body mass index. Long: long protocol; IPM: improved prolonged protocol in the midluteal phase; IPF: improved prolonged protocol in the follicular phase; AFC: antral follicle counts.
