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.


METHODS
Prospective observational study.


METHODS
University hospital-based fertility clinic.


METHODS
Thirty-six patients undergoing intrauterine insemination (IUI).


METHODS
Ultrasound observation before and after IUI.


METHODS
Endometrial wave type and endometrial wave frequency before and after IUI.


RESULTS
There was no difference in the direction and frequency of endometrial waves before and after IUI in 36 patients.


CONCLUSIONS
Although the induction of uterine contractions by intrauterine manipulation has been suggested in the literature, the present study shows no contractions or induction of unfavorable (fundus to cervix) endometrial wavelike activity in 36 patients undergoing IUI.
