Brief summary
This large prospective multi-center cohort study aims to identify patient's characteristics that significantly influence ovarian response to mild stimulation with a fixed dose of 75 IU recombinant FSH.
Detailed description
A multi-center, open-label, prospective cohorts study. Patients with a regular indication for COH/IUI (controlled ovarian stimulation/ intra uterine insemination) will be asked to participate. Patient's characteristics will be documented including age, weight, BMI, smoking status, cycle day 2 3 or 4 FSH /Estradiol levels, antral follicle count, and AMH. AMH and FSH/Estradiol will be determined centrally after completion of inclusion of all patients in the study. All patients will receive a fixed 75 IU recFSH per day conform normal stimulation protocol starting from cycle day 3, 4 or 5 after exclusion of ovarian cysts by ultrasound. Ovarian response will be documented by ultrasound only. Once the dominant follicle(s) reach a mean diameter of 16-18 mm, hCG (5000IU or 250 mcg) will be applied and insemination will be scheduled 36-42 hours later. Cancellation criteria will be defined according to the national guidelines provided by the NVOG (7).
Interventions
All patients will receive a fixed 75 IU rec follicle stimulating hormone per day subcutaneous injection stimulation protocol starting from cycle day 3, 4 or 5. The intervention done in this study is conform normal stimulation protocol and is not the target of this study.

Inclusion criteria
* couples with unexplained or mild male subfertility (1-3) and a spontaneous chance of conception below 40% (Hunault score). * Unexplained subfertility including minimal to mild endometriosis (AFS grade 1 or 2) is defined as the failure to conceive after at least one year of unprotected intercourse whereas the standard fertility work-up was unable to detect any factors that might influence fertility negatively. * semen analysis should be normal according to the WHO guidelines (8), * ovulation should be documented (by BBT charts, ovulation detection by ultrasound or normal luteal progesterone values), * tubal patency should be confirmed (HSG, laparoscopy or fertiloscopy) and when a postcoital test was performed a cervical factor should have been excluded. * Mild male subfertility is defined as abnormal semen parameters according to the WHO (8) but an average total motile sperm account before processing of at least 10 million.
Exclusion criteria
* Hunault score ≥ 40% * Endometriosis AFS grade 3 or 4 * Contra-indications for the use of gonadotrophins (cysts larger than 2 cm, allergy for gonadotrophins) * Total motile sperm count after sperm processing below 1 million * Women aged younger than eighteen years or older than 45 years. * Previous treatment with COH/IUI for treating current subfertility * Unable to speak or read the Dutch language
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| To assess the relationship between AMH serum levels and ovarian response | one menstrual cycle, one month | (defined by the number of dominant follicles \>15mm) in IUI cycles stimulated with a fixed dose of 75 IU recFSH. All follicles \> 11 mm will be documented |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| To assess the relationship between age, weight, BMI, smoking, AFC, FSH/E2 on CD3 and ovarian response | one menstrual cycle, one month | (defined by the number of dominant follicles \>15mm) in IUI cycles stimulated with a fixed dose of 75 IU recFSH. |
| Pregnancy rate per started cycle. | three months | From start of the menstrual cycle until a positive heartbeat registered at 12 weeks of gestation. |
| Multiple pregnancy rate per started cycle. | three months | From start of the menstrual cycle until positive heartbeats registered at 12 weeks of gestation. |
| Miscarriage rate per started cycle. | five months | miscarriage up to 16 weeks of gestation |
| Cancellation rate per stimulated cycle | one menstrual cycle, one month | — |
