Atosiban, administered at embryo transfer, can improve the implantation rate and the clinical pregnancy rate in patients with repeated implantation failure undergoing IVF-ET (in-vitro fertilization and embryo transfer).

Condition Intervention

Primary Outcome Measures:
  • Clinical pregnancy [ Time Frame: 5 weeks after intervention ]

Enrollment: 71
Study Start Date: March 2011
Study Completion Date: September 2011
Primary Completion Date: August 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Atosiban Drug: atosiban
Atosiban was administered as a 6.75mg IV bolus dose 30 minutes prior to embryo transfer followed by a 1-hour IV infusion at dose of 18 mg/h then a 2-hour IV infusion at 6 mg/h.
Other Name: Tractocile

Detailed Description:
Atosiban is a mixed oxytocin and vasopressin V1A receptor antagonist.Combined antagonism at oxytocin and vasopressin V1A receptors reduces uterine contractions with a corresponding decrease in intrauterine production of prostaglandin F2alpha and improved uterine blood supply. These effects are of potential benefit for implantation support during IVF-ET cycles.

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   Female
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • had repeated implantation failure
  • have at least 1 good quality embryo for transfer

Exclusion Criteria:

  • uterine abnormalities that could compromise the implantation process (e.g. fibroids, endometrial polyp, bicornuate uterus, adhesion of uterine cavity)
