Effects of catheter depth and infused semen volume on the pregnancy of intrauterine insemination / 中华男科学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the effects of catheter depth and infused semen volume on the pregnancy rate of intrauterine insemination(IUI) with the husband's semen.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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).</p><p><b>CONCLUSIONS</b>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.</p>
