Brief summary

Ten to 15 percent of couples in their reproductive lifetime face fertility problems which is defined by WHO as the absence of pregnancy after minimal 12 months of unprotected sexual intercourse. The three most frequent causes of subfertility are: sperm defects, ovulation disorders and tubal pathology. In order to exclude tubal pathology, tubal patency tests are performed under ultrasound guidance with foam (hysterosalpingo-foam sonography (Hyfosy)) or with contrast/water (hysterosalpingo-contrast sonography (Hycosy)). This trial will investigate whether tubal flushing with an oil-soluble contrast medium (OSCM) can increase the likelihood of a spontaneous conception after tubal patency testing with Hyfosy under ultrasound guidance compared to no additional flushing in a population of infertile women between 18 and 40 years of age with absence of pregnancy after 12 months of unprotected sexual intercourse or who have three cycles of donor insemination without pregnancy or three ovulatory ovulation induction cycles without pregnancy. The use of Lipiodol Ultra Fluide® is off-label in Hyfosy. This multicenter, randomised, open-label, comparative and pragmatic trial compares 2 arms which will be randomised 1:1: * Intervention group: Tubal flush with 5-10mL oil-soluble contrast medium (Lipiodol Ultra Fluide®, Guerbet, France) immediately after Hyfosy * Control group: No additional intervention after Hyfosy The study comprises a screening period of maximum 8 weeks (w-8 to d1), randomisation (w-8 to d1), a start study visit at which the Hyfosy is performed (d1) and a fertility treatment period of 6 months (d1-w26). If the woman is not pregnant at 6 months after Hyfosy, the follow-up will last till 12 months (w52). If the participant is pregnant at 6 months after Hyfosy, the follow-up will last till maximal 4 months after live birth or miscarriage. The primary endpoint is the occurrence of live birth, with the first day of the last menstrual cycle in which the patient conceives within 6 months after Hyfosy. Secondary endpoints consist of reproductive outcomes, gestational age at delivery, birth weight, neonatal mortality, major congenital anomaly, neonatal outcomes and thyroid function, pregnancy complications, number of complications during or immediately after the intervention, pain score of the Hyfosy and additional flush, thyroid function of the mother, general and disease-specific quality of life.

Women will be eligible if they * are ≥ 18 years and \< 40 years * have infertility defined as * lack of conception despite 12 months of unprotected intercourse OR; * if they are taking part in a donor sperm insemination programme: three cycles of donor insemination without pregnancy OR; * in case of treated ovulation disorder: three ovulatory ovulation induction cycles without pregnancy * have tubal patency of at least one Fallopian tube on Hyfosy

Exclusion criteria
