| Scientific title | Prevention of multiple pregnancies in couples with unexplained or mild male subfertility |
| Study acronym | INeS-study |
| Study objectives | Multiple pregnancies can be prevented without loss of pregnancy rates by treating couples with manipulated natural cycle In Vitro Fertilisation (IVF) or with IVF-eSET (Single Embryo Transfer) plus cryo-cycles instead of standard treatment with intra-uterine insemination and controlled ovarian hyperstimulation. |
| Ethics approval(s) | Ethics approval received from the local medical ethics committee |
| Health condition(s) or problem(s) studied | Multiple pregnancies |
| Intervention | The comparisons are: 1. Six cycles of intra-uterine insemination with controlled ovarian hyperstimulation 2. Six cycles of manipulated natural cycle IVF 3. Three cycles with IVF-eSET plus cryo-cycles Performed within a time frame of 10 months |
| Intervention type | Other |
| Primary outcome measure(s) |
