|
| Control, non-RIF | No Intervention | No intervention. Women with no more than 1 previous unsuccessful embryo transfer. | |
| Endoscratching, RIF | Experimental | Endometrial scratching. Women with 2 or more previous unsuccessful embryo transfers. Pipelle in the first seven days of the menstrual cycle, just before starting controlled ovarian stimulation. |
|
| Control, RIF | No Intervention | No intervention. Women with 2 or more previous unsuccessful embryo transfers. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Endometrial Scratching | Procedure | The intentional damage to the endometrium performed with the objective of improving the reproductive outcomes of women desiring pregnancy. |
|
| Measure | Description | Time Frame |
|---|---|---|
| Live birth | The number of participants who delivered a living baby in each arm. The denominator will be the number of women randomized to each arm. This outcome will be assessed by examining the medical records and telephone contact. | 1 year |
| Measure | Description | Time Frame |
|---|---|---|
| Clinical pregnancy | The number of participants achieved clinical pregnancy detected by ultrasound (either intrauterine or ectopic). The denominator will be the number of women randomized to each arm. This outcome will be assessed by examining the medical records and telephone contact. | 8 weeks |
| Miscarriage |
| Measure | Description | Time Frame |
|---|---|---|
| Implantation rate | The number of gestational sacs divided by the number of transferred embryos in each arm. This outcome will be assessed by examining the medical records. | 8 weeks |

The number of participants who experienced spontaneous loss of a clinical pregnancy before 20 completed weeks of gestational age. The denominator will be the number of women who achieved clinical pregnancy in each arm. This outcome will be assessed by examining the medical records and telephone contact. |
| 20 weeks |
| Multiple pregnancy | The number of pregnant participants with more than one gestational sac (twins/triplets). The denominator will be the number of women who achieved clinical pregnancy in each arm. This outcome will be assessed by examining the medical records and telephone contact. | 8 weeks |
