| Label | Type | Description | Intervention Names |
|---|---|---|---|
| CC-Test diagnosis and Day 3 transfer | Experimental | Patients undergo the standard ART treatment, as prescribed by the treating physician, with standard morphology based scoring of the embryos + the extra cumulus cell based diagnosis and transfer of the best embryo based on morphology and CC diagnosis on day 3 of embryo growth (cleavage stage embryo) |
|
| Day 3 transfer control group | No Intervention | Patients undergo the standard ART treatment, as prescribed by the treating physician, with standard morphology based scoring of the embryos and transfer of the best embryo based on day 3 of embryo growth (cleavage stage embryo) | |
| Day 5 transfer control group | No Intervention | Patients undergo the standard ART treatment, as prescribed by the treating physician, with standard morphology based scoring of the embryos and transfer of the best embryo based on day 5 of embryo growth (blastocyst stage embryo) |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| CC-Test | Other | Classification of the oocyte/embryo based on the expression pattern observed in the cumulus cells |

This observation is routinely performed by the study nurses of the fertility center for every patient undergoing standard ART treatment and is thus available from the fertility center database.This measurement does not include a scale, there is either a child born or not. The date of delivery and the gender of the child are asked together with eventual complications. |
| at least 9 months after embryo transfer |
| Cumulative pregnancy | This is the compilation of the data gathered in outcome 1 and 3 for eventual consecutive cycles. This observation is routinely performed by the study nurses of the fertility center for every patient undergoing standard ART treatment and is thus available from the fertility center database. | 2 years after embryo transfer |
