Pregnancy outcome per patient in VET and cumulative pregnancy rate after fresh embryo transfer and VET
| D3 group (n = 46) | D5 group (n = 58) | Statistical significance | |
|---|---|---|---|
| Patients with no ongoing pregnancy in fresh IVF with vitrified embryos | 65.7 % (23/35) | 54.4 % (18/33) | p = 0.347 |
| Patients going through VET | 87 % (20/23) | 88.8 % (16/18) | p = 0.369 |
| No. VET transfers/patient | 1.1 ± 0.6 (22/20) | 1.5 ± 0.9 (24/16) | p = 0.236 |
| No. Embryos transferred/cycle | 1.7 ± 0.47 | 1.33 ± 0.48 | p = 0.02 |
| Embryo survival rate | 78.8 % (37/47) | 82.1 % (32/39) | p = 0.7 |
| Clinical pregnancy rate/ VET cycle | 50 % (11/22) | 41.6 % (10/24) | p = 0.571 |
| Implantation rate | 43.2 % (16/37) | 34.4 % (11/32) | p = 0.452 |
| Miscarriage rate | 18.1 % (2/11) | 20 % (2/10) | p = 0.916 |
| Multiple pregnancy rate | 45.4 % (5/11) | 10 % (1/10) | p = 0.072 |
| Ongoing pregnancy rate/patient in VET | 45 % (9/20) | 50 % (8/16) | p = 1.000 |
| Cumulative ongoing pregnancy rate/ patient (fresh + VET) | 43.4 % (20/46) | 56.8 % (33/58) | p = 0.174 |
