In the 7 days estradiol (E2) arm (A) the study coordinator will plan the FET after 6 days of progesterone supplementation (13 days of E2 intake). In the 14 days E2 arm (B) the team will plan on day 14 of treatment with E2 the serum hormone evaluation and an ultrasound in order to evaluate the endometrium thickness, consequently the FET will be planned after 6 days of progesterone supplementation (after 14 days of E2 intake). Furthermore, all the patients included in the study will undergo a blood test on the day of the transfer for the evaluation of the hormones level. For the assessment of the pregnancy a first blood test will take place 12 days after the ET and a blood test with an ultrasound will take place at 7 weeks for the evaluation of the clinical pregnancy.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT'], 'maximumAge': '40 Years', 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': '* Women aged ≥18 and \\< 40 years\n* Unexplained infertility\n* Normal uterine cavity\n* IVF/ICSI\n* IVF cycle with GnRH agonist or antagonist\n* Single day 5 blastocyst transfer\n* Top quality embryo (at least Bl 3BA) at the moment of ET\n* Signed informed consent\n* Participants can be included only once in the trial\n* Informed consent documents signed prior to screening evalua-tions.'}, 'identificationModule': {'nctId': 'NCT03930706', 'acronym': 'ShoRT', 'briefTitle': 'SHorter Treatment of Replacement Therapy for Frozen Embryo Transfer (FET)', 'organization': {'class': 'OTHER', 'fullName': 'Universitair Ziekenhuis Brussel'}, 'officialTitle': 'Clinical Pregnancy Rate for Frozen Embryo Transfer With Hormonal Replacement Therapy (HRT): a Pilot Study Comparing 1 Versus 2 Weeks of Treatment', 'orgStudyIdInfo': {'id': 'HRT1vs2week.2018'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Group A', 'description': 'Group A will include all the patient that will start with progesterone ((P), Utrogestan®) supplementation after 7 days of E2 (Progynova®) intake and that will perform the FET (after 13 days of E2 and 6 days of P).', 'interventionNames': ['Other: Longer administration of estradiol (Progynova®)']}, {'type': 'ACTIVE_COMPARATOR', 'label': 'Group B', 'description': 'Group B will include the patients that will perform 14 days of E2 intake (Progynova®, 6 mg per day (2 mg every 8 hours) those patients will be asked to perform a supplementary blood test and ultrasound on day 14 of E2 intake, afterwards, they will start with P supplementation (Utrogestan®, 800 mg per day, 400 mg every 12 hours) from day 15 of E2 for 6 days and they will get their FET day 20 of the cycle (after 14 days of E2 and 6 days of P)', 'interventionNames': ['Other: Longer administration of estradiol (Progynova®)']}], 'interventions': [{'name': 'Longer administration of estradiol (Progynova®)', 'type': 'OTHER', 'otherNames': ['comparing 7 vs 14 days of administration of estradiol (Progynova®) for artificially prepared endometrium in frozen embryo transfer'], 'description': 'All women included will take exogenous hormone with daily administration of Estradiol Valerate (Progynova®), the standard dose used will be 6 mg/day (Cobo et al., n.d.).
