Study information
Scientific title
Acronym
IUI study IMP 26162
Study hypothesis
We hypothesize that the use of a GnRH-antagonist in cycles with Mild Ovarian Hyperstimulation (MOH) combined with Intrauterine insemination (IUI) programs significantly improves live birth rates compared with MOH and a placebo.
Ethics approval
Received from local medical ethics committee
Study design
Multicentre randomised double blind placebo controlled parallel group trial
Primary study design
Interventional
Secondary study design
Randomised controlled trial
Trial setting

Patient information sheet
Condition
Intrauterine Insemination (IUI), Infertility, Subfertility
Intervention
The research group of patients will consist of two arms:
One group will receive ovarian stimulation with recFSH combined with placebo (the recFSH group).
One group will receive recFSH combined with a GnRH-antagonist (the recFSH-anta group).
Both ovarian stimulation protocols will be followed by intrauterine insemination.

Primary outcome measure
Live birth rate per couple
Secondary outcome measures
1. Total costs and cost-effectiveness
2. Ongoing (>12 weeks amenorrhoea) pregnancy rate per cycle commenced
3. Miscarriages (Preclinical miscarriage: spontaneous cessation of a biochemical pregnancy. Early miscarriage: any spontaneous abortion occurring after confirmation of clinical pregnancy and before completed 12 weeks of gestation. Late miscarriage: any spontaneous abortion occurring between completed 12 weeks of gestation and 16 completed weeks of gestation.) and ectopic pregnancies
4. Cumulative ongoing pregnancy rates per couple
5. Multiple births including the chorionicity
6. The occurrence of an LH surge or premature luteinization
7. Response of the ovaries to stimulation (number of follicles on day of Ovitrelle administration, speed of development, length of stimulation, quantities of medication used, etc.)

Eligibility
Participant inclusion criteria
Primary and secondary subfertile patients between 18 and 35 years of age with a diagnosis of unexplained or mild male infertility will be included.
Definition of unexplained subfertility:
1. Normozoospermia using the guidelines of the WHO
2. Patent Fallopian tubes (both ovaries should be in situ)
3. Cycles varying between 24 and 35 days with an indication of ovulation
4. No abnormalities at laparoscopy and/or hysterosalpingography
Information from the post-coital test when performed will only be used for a prognostic model and not as an exclusion criterion.

Target number of participants

Participant exclusion criteria
1. Age of the woman <18 or >35 years
2. Duration of subfertility below 2 years
3. Manifest pathology of the Fallopian tubes
4. Severe forms of endometriosis (when laparoscopy has been performed: >AFS II)
5. An average total number of motile spermatozoa during semen analysis (performed twice in case of abnormal findings) below 10 million
6. Cycle disturbances (where otherwise ovulation induction would be used)
7. Previous IUI or IVF/ICSI treatment
8. If an initial ultrasound shows an image of a cyst that is larger than 25 mm treatment will be postponed for 1 month. Persistence of a cyst is a reason for exclusion.
9. Contraindications for recFSH (Gonal-F), rec-hCG (Ovitrelle) and Cetrotide
