Eligibility

Inclusion criteria

Inclusion criteria: 1. Couples with unexplained subfertility or mild subfertility; 2. Age between 18 and 38 years; 3. Referred by a general practitioner or on own initiative; 4. No previous fertility treatment in medical history; 5. A prognosis of more than 30 percent chance of natural conception within one year based on the prediction model of Hunault.

Exclusion criteria

Exclusion criteria: 1. Age 38 years or older; 2. Fertility treatment in medical history; 3. Referred by another gynaecologist, fertility doctor; 4. Anovulation: Menstrual cycle of less than 24 days or more than 35 days / no menses for over 6 months; 5. Two-sided tubal pathology. Diagnosed by a HCG or laparoscopy; 6. Severe male subfertility. VCM< 3 million (< 3 x 10^6); 7. Couples with a prognosis of less than 30 percent chance of natural conception within one year based on the prediction model of Hunault.

Design outcomes

Primary

MeasureTime frame
The primary outcome is the effect of the strategy on the adherence to tailored expectant management. Measured by the difference in the percentage of couples with unexplained subfertility, with a good prognosis of spontaneous conception within one year (>30%), with tailored expectant management in the year before the intervention and during the intervention period.

Secondary

MeasureTime frame
1. Treatment outcome related measures like ongoing pregnancy and multiple pregnancy rates, time to pregnancy; 2. Process related measures like percentage transition of patients to another fertility centre and patient related outcome measures like quality of life (FertiQoL) and general experiences with fertility care such as information provision, respect for patients’ values and accessibility of care (Patient Centeredness Questionnaire Infertility); 3. A process related evaluation will assess the intensity of exposure to all the different strategy elements per patient, per clinic and per region. In addition, the feasibility and usefulness of all strategy elements will be evaluated; 4. We will investigate the cost-effectiveness of the multifaceted strategy to implement tailored expectant management. This economic evaluation compares a multifaceted implementation strategy to usual care and is done from a healthcare perspective.
