The candidates were selected for this study in the clinics of Tabriz University of Medical Sciences, East Azarbayejan Province, North West of Iran, from Oct. 2006 to Sep. 2007. Infertile women who had chronic anovulation and classical PCOS with CC+hCG failure were age \\<40 y , had patent tubes on hysterosalpingography, and no other pelvic pathology, participated in this study. The patients who had hypersensivity to any oxytocic medications, history of cardiovascular disease, and took anti-hypertensive medications were excluded. In addition, women with blood pressure less than 90/60 mmHg, abnormal spermogram, anxiety, excess prolactin levels, and other causes of infertility were excluded. All participants were given adequate information, and consent was obtained from each participant.\n\nThe candidates were randomly divided into five groups including; letrozole + hCG (36 patients) (group 1), letrozole + OT (35 patients) (group 2), letrozole +OT + hCG (35 patients) (group 3), CC + OT (35 patients) (group 4), and CC + OT + hCG (36 patients) (group 5). Participants received letrozole 2.5mg at first month and 5mg at the second and third month. Also, CC was used 50 mg at the first month, to 150 mg at the third month to stimulate follicular growth. Oxytocin (OXYTIP; manufactured by IPDIC, Rasht, Iran), 5 IU and hCG (Choriomon; manufactured by IBSA Institute Biochimique SA, CH-6903 Lugano), 5000 IU were also administrated to induce ovulation. All patients underwent transvaginal sonography on day 13 to document the numbers of follicles and endometrial thickness. Participants were evaluated for three courses of intervention. Oxytocin was injected intramuscularly after CC or letrozol stimulation had induced enlarged ovarian follicles ( \\>18 mm in diameter to 30 mm). Decision to give a 5 IU dose of OT was made according to the pilot study (30). The patients who had larger follicles (more than 30mm in diameter), were withdrawn. The patients, who achieved pregnancy at the first or second month, were also withdrawn. All participants were evaluated for the levels of plasma progesterone one week after the injection of OT, hCG, or combination of them. A follow-up visit was arranged for each group every month at the second day of menstruation until 3 months after recruitment or at any time during the trial if pregnancy was achieved.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['CHILD', 'ADULT'], 'maximumAge': '40 Years', 'minimumAge': '17 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* infertile women who had chronic anovulation\n* classical PCOS with CC+hCG failure\n* age \\<40 y\n* had patent tubes on hysterosalpingography\n* no other pelvic pathology\n* participated in this study\n\nExclusion Criteria:\n\n* hypersensitivity to any oxytocic medications\n* history of cardiovascular disease\n* took anti-hypertensive medications were excluded.\n* women with blood pressure less than 90/60 mmHg\n* abnormal spermogram\n* anxiety\n* excess prolactin levels\n* other causes of infertility were excluded'}, 'identificationModule': {'nctId': 'NCT00844350', 'briefTitle': 'The Effect of Oxytocin (OT) and Oxytocin Plus Human Chorionic Gonadotropin (hCG), in Cycles Induced by Letrozole or Clomiphene Citrate', 'organization': {'class': 'OTHER', 'fullName': 'Tabriz University'}, 'orgStudyIdInfo': {'id': '8725'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'NO_INTERVENTION', 'label': 'letrozole+hCG', 'interventionNames': ['Drug: letrozole , oxytocin,hCG,clomiphene citrate']}, {'type': 'NO_INTERVENTION', 'label': 'letrozole+oxytocin', 'interventionNames': ['Drug: letrozole , oxytocin,hCG,clomiphene citrate']}, {'type': 'NO_INTERVENTION', 'label': 'letrozole+oxytocin+hCG', 'interventionNames': ['Drug: letrozole , oxytocin,hCG,clomiphene citrate']}, {'type': 'NO_INTERVENTION', 'label': 'clomiphene citrate +oxytocin', 'interventionNames': ['Drug: letrozole , oxytocin,hCG,clomiphene citrate']}, {'type': 'NO_INTERVENTION', 'label': 'clomiphene citrate +oxytocin+hCG', 'interventionNames': ['Drug: letrozole , oxytocin,hCG,clomiphene citrate']}], 'interventions': [{'name': 'letrozole , oxytocin,hCG,clomiphene citrate', 'type': 'DRUG', 'armGroupLabels': ['clomiphene citrate +oxytocin', 'clomiphene citrate +oxytocin+hCG', 'letrozole+hCG', 'letrozole+oxytocin', 'letrozole+oxytocin+hCG']}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Tabriz University', 'class': 'OTHER'}, 'responsibleParty': {'oldNameTitle': 'Manizhe sayyah melli', 'oldOrganization': 'Tabriz university of medical scince'}}}}
