OC091: Spontaneous uterine contractions involving sub endometrial myometrium influence endometrial perfusion and?uterine receptivity

Abstract

Oral communication abstracts significantly (p = 0.12). Furthermore, more conspicuous results were revealed by the qualitative analysis: eight subjects (44.44%) presented ''abnormal'' spectra according to Goswamy and Steptoe's waveform classification i.e. type A (n = 1), type B (n = 3) and type O (absent diastolic blood flow) (n = 4); all of them recovered type C waveforms (normal spectrum) during the hour following nifedipine dispensation. Conclusions: Nifedipine induced a reversible enhancement of uterine arterial blood flow. Restoring diastolic blood flow provides a compelling evidence that nifedipine is a potent drug which may improve embryonic implantation in case of abnormal uterine vascularization.
