Study setting(s)Hospital
Study typePrevention
Scientific titlePrevention of multiple pregnancies in couples with unexplained or mild male subfertility
Study acronymINeS-study
Study objectivesMultiple 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) studiedMultiple pregnancies
InterventionThe 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 typeOther
Primary outcome measureBirth of a healthy child.
Secondary outcome measures1. Multiple pregnancy, defined as registered heartbeat of at least two foetuses at 12 weeks of gestation
2. Clinical pregnancy, defined as any registered embryonic heartbeat at sonography
3. Neonatal mortality
4. Pregnancy complications:
a. preterm birth less than 37 weeks
b. birth weight less than 2.500 grams
c. Pregnancy Induced Hypertension (PIH)
d. (pre)-eclampsia, HELLP (Haemolysis, Elevated Liver enzymes, Low blood levels of Platelets)
5. Costs
