US-guided fallopian tube catheterization.
Ultrasound-guided fallopian tube catheterization was performed in seven women a total of 14 times. The women had normal-appearing fallopian tubes at hysterosalpingography and received sperm via the catheter as a way to overcome their inability to conceive. Techniques similar to those used for fluoroscopically guided fallopian tube catheterization were used. Forty-three percent of fallopian tubes were successfully catheterized.
