A randomised, double-blind, parallel groups, placebo-controlled, multi-centre study assessing the effects of a selective oxytocin antagonist (barusiban) and a mixed oxytocin antagonist – vasopressin V1a antagonist (atosiban) administered intravenously on luteal phase uterine contractions in oocyte donors supplemented with vaginal progesterone - OVANCO

Inclusion Criteria

1.Signed informed consent form, prior to screening evaluations
2.Oocyte donors who have undergone controlled ovarian hyperstimulation in the long GnRH agonist protocol or the multiple-dose or single-dose GnRH antagonist protocols, have received hCG (= 5,000 IU urinary hCG or 250 µg recombinant hCG) for triggering final follicular maturation and have undergone oocyte retrieval (OR) in the current cycle

7.Good visualisation of the entire volume of the uterus in the maximum longitudinal (mid-sagittal) plane from cervix to fundus, including the entire endometrium, myometrium and serosa at the transvaginal ultrasound at screening (Day OR +1)
8.Willing to not have sexual intercourse during the study and to either maintain sexual abstinence or to use a highly effective method of contraception (i.e. a failure rate of less than 1% per year, such as intrauterine device) from end-of-study until onset of next menses
9.Willing to not have intake of alcoholic beverages during the study
