Intrauterine manipulation does not adversely influence the direction and frequency of endometrial waves.

Objective: To investigate whether intrauterine manipulation affects the direction or alters the frequency of endometrial wavelike activity.

Design: Prospective observational study.

Setting: University hospital-based fertility clinic.

Complex endometrial wave-patterns in IVF.

Objective: To reanalyze ultrasound images from IVF cycles with the aim of developing a refined endometrial wave classification system, which will allow description as well of the more complex endometrial wave patterns.

Design: Descriptive study.

Setting: University hospital-based fertility clinic.

Endometrial waves in in vitro fertilization cycles: a validation study.

In a prospective validation study we could not confirm that the persistence of endometrial waves from fundus to cervix on the day of hCG administration is associated with a favorable pregnancy prognosis in patients undergoing IVF.

Menstrual effluent induces epithelial-mesenchymal transitions in mesothelial cells.

Background: Menstrual effluent affects mesothelial cell (MC) morphology. We evaluated whether these changes were consistent with epithelial-mesenchymal transitions (EMT).

Methods: Monolayer cultures of MC were incubated overnight in conditioned media, prepared from cells isolated form menstrual effluent, with or without kinase and ATP inhibitors.

Adhesion of shed menstrual tissue in an in-vitro model using amnion and peritoneum: a light and electron microscopic study.

We have investigated the adhesion of endometrial tissue isolated from antegradely shed menstrual effluent to amnion and peritoneum. This endometrial tissue was cultured overnight on either side of intact and stripped amnion and on the mesothelial side of peritoneum. Light and electron microscopy were applied to evaluate adhesion.
