Research questionTo explore normal uterine contractile function across the menstrual cycle using a novel quantitative ultrasound method.DesignThis multicentre prospective observational study took place in three European centres from 2014 to…

Contractions of the non-pregnant uterus play a key role in fertility. Yet, the electrophysiology underlying these contractions is poorly understood. In this paper, we investigate the presence of uterine electrical activity and characterize …

Measurement and analysis of uterine contractions (UC) through a machine-learning model based on quantitative 2D and 3D transvaginal ultrasound (TVUS) measurements in women with abnormal uteri due to adenomyosis, leiomyomas or uterine anomal…

PurposeContractions in non-pregnant uterine can be assessed by visual inspection of transvaginal ultrasound (TVUS). Many authors have used this method to extract features like contraction frequency and direction. However, visual inspection …

PurposeUterine activity plays a key role in reproduction, and altered patterns of uterine contractility have been associated with important physiopathological conditions, such as subfertility, dysmenorrhea, and endometriosis. However, there…

It has been postulated that increased uterine peristalsis (UP) negatively influences in vitro fertilisation outcome due to endometrial hyper-contractility after embryo transfer. An objective and non-invasive characterisation of UP can there…
