Secondary study designRandomised controlled trial
Study setting(s)Not specified
Study typeTreatment
Scientific titleTreatment of couples with unexplained subfertility and an unfavourable prognosis: a randomised trial comparing the effectiveness of intrauterine insemination with ovarian hyperstimulation and in-vitro fertilisation with single embryo transfer
Study acronymSETI-study (Single Embryo Transfer or IUI)
Study objectivesOne cycle of In-Vitro Fertilisation-elective Single Embryo Transfer (IVF-eSET) followed by transfer of frozen embryos is at least as effective as three cycles of Intra-Uterine Insemination-Controlled Ovarian Hyperstimulation (IUI-COH) in terms of ongoing pregnancy. Multiple pregnancies however can largely be prevented by treating women with IVF-eSET.
Ethics approval(s)Approval received from the ethics board of the Academic Medical Centre Amsterdam on March 6th 2006 (reference number: MEC 294).
Health condition(s) or problem(s) studiedUnexplained Subfertility
InterventionComparison of IVF in a long protocol with elective Single Embryo Transfer, and IUI-COH, in couples with unexplained or mild male subfertility and poor fertility prospects.
Intervention typeOther
Primary outcome measureOngoing pregnancy defined as registered heartbeat on ultrasound beyond 12 weeks of gestation.
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. Live birth, defined as the birth of at least one living child
4. Pregnancy complications (preterm birth less than 37 weeks, birth weight less than 2.5 gram, Pregnancy Induced Hypertension (PIH), (pre-) eclampsia, Haemolysis, Elevated Liver, Low Platelet [HELLP])

Target number of participants100
Total final enrolment116
Key inclusion criteria1. Female age between 18 and 36 years
2. Couples must be diagnosed with unexplained subfertility, defined as normal semen (pre-wash total motile sperm count of at least 40 million), spontaneous ovulatory cycle and patent Fallopian tubes, or with mild male subfertility, defined as a post-wash total motile sperm count above three million
