Abstract: Method of analyzing uterine contractions by analyzing uterine images using deformable model networks in support of embryo transfer techniques. The method is also used to diagnose premature uterine contractile activity in mammals. The method can be used to control contractile activity during embryo transfer or premature labor when used in conjunction with oxytocin antagonists.

Abstract: The present invention relates to the use of antagonists of oxytocin, antagonists of oxytocin and vasopressin, or antagonists of vasopressin, or their pharmaceutically accepted salts, or their combinations with other drugs for the manufacture of a medicament which main profile of action is inhibition of oxytocin and/or vasopressin receptors in non-pregnant uterus of mammals, that results in improvement of uterine receptivity in embryo transfer. It further relates to the application of these substances for the manufacture of a medicament for regulating the uterine contractile activity in cases of artificial insemination.
