Primary
| Measure | Time frame |
|---|---|
| Difference between day means in endometrial priming to achieve 7 mm. | 11-16 days |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Biochemical Pregnancy rate | 26-30 days | To calculate the biochemical pregnancy rate, we will divide the number of biochemical pregnancy into the number of embryonary transference and multiply by 100. |
