[Effects of catheter depth and infused semen volume on the pregnancy of intrauterine insemination].
OBJECTIVE
To evaluate the effects of catheter depth and infused semen volume on the pregnancy rate of intrauterine insemination(IUI) with the husband's semen.


METHODS
According to different catheterizing distances from the fundus and infused semen volumes, 330 patients undergoing intrauterine insemination were randomly divided into 6 groups: A, 1 cm/0.5 ml; B, 1 cm/0.3 ml; C, 2 cm/0.5 ml; D, 2 cm/0.3 ml; E, 3 cm/0.5 ml and F, 3 cm/0.3 ml. The pregnancy rate was investigated in each group.


RESULTS
The pregnancy rates from group A to group E were 9.09% (5/55), 12.73% (7/55), 10.91% (6/55), 29.09% (16/55), 9.09% (5/55) and 12.73% (7/55), respectively. It was significantly higher in group D than in groups A, B, C, E and F(P < 0.05).


CONCLUSIONS
Catheterizing distance of 2 cm from the fundus with infused semen volume of 0.3 ml can significantly improve pregnancy rate in patients undergoing IUI with the husband's semen.
