Subendometrial Contractions in Subfertile Women : A Preliminary Observation

Abstract

Fifty endovaginal ultrasonographic examinations were screened for the presence of subendometrial myometrial contractions in subfertile women. The contractions were evaluated during the periovulatory phase of ovulation induction programs. The results showed that the contractions can be divided into 3 types according to directions. (1) Retrograde type, was the direction from endocervix to the fundus. (2) Antegrade type, was the direction from the fundus to endocervix. (3) Turbulent type, contractions moved in alternating directions over a short segment. More than half of the contractions observed are turbulent type. The con clusion is that there are definite patterns of subendometrial contractions in subfertile women but with a significant difference in percentage compared to study in fertile women.
