Criteria

Inclusion Criteria:

• The trial only includes women with a clinical indication for ART with a history of RIF defined as the absence of implantation after two consecutive cycles of IVF, ICSI or frozen embryo replacement cycles where the cumulative number of transferred embryos was no less than four for cleavage-stage embryos and no less than two for blastocysts, with all embryos being of good quality and of appropriate developmental stage.

Furthermore, other specific 'RIF' investigations were performed and treated if necessary:

• Normal hysteroscopy

• Normal karyotype of both parents

• Coagulation screening (Antitrombine II deficiency, Factor VIII augmentation, APC resistance, Factor V + Factor II augmentation, Protein S and C deficiency an homocysteine augmentation)

• Auto-immune screening (Lupus anticoagulant, Rheumatoid Factor, Anti-nuclear antibodies, Anti-cardiolipine antibodies and Glycoprotein-1-antibodies)

Exclusion Criteria:

• • Simultaneous participation in another clinical study

• Untreated and uncontrolled thyroid dysfunction

• Tumors of the ovary, breast, uterus, pituitary or hypothalamus

• Abnormal (not menstrual) vaginal bleeding without a known/diagnosed cause

• Ovarian cysts or enlarged ovaries

• Malformations of the reproductive organs

• Moderate or severe hepatic impairment

• Current use of oral contraceptives, anti-psychotics, anti-epileptics or chemotherapy

• Patients who undergo preimplantation genetic testing (PGT), fertility preservation or oocyte donation

• Couples needing TESE/MESA material
