Study information

Primary study design	Interventional
Study design	Randomised, controlled, parallel group multicentre trial
Secondary study design	Randomised controlled trial
Scientific title	Treatment 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 acronym	SETI-study (Single Embryo Transfer or IUI)
Study objectives	One 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) studied	Unexplained Subfertility
Intervention	Comparison 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 type	Other
Primary outcome measure(s)	Ongoing pregnancy defined as registered heartbeat on ultrasound beyond 12 weeks of gestation.
Key secondary outcome measure(s)	1. 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])
Completion date	01/06/2008

Eligibility

Participant type(s)	Patient
Age group	Adult
Lower age limit	18 Years
Sex	Female
Target sample size at registration	100
Total final enrolment	116
Key inclusion criteria	1. 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 3. The couple has poor fertility prospects as calculated by the validated model of Hunault. A poor fertility prospect is defined as a chance of spontaneous pregnancy below 30% within 12 months
Key exclusion criteria	1. Polycystic ovary syndrome 2. Endocrinopathological disease like: Cushing syndrome, adrenal hyperplasia, hyperprolactinemia, acromegaly, imminent ovarian failure, premature ovarian failure, hypothalamic amenorrhea, hypothyroidy, diabetes mellitus type I 3.
