Modern Examination of Fallopian Tube Patency Using Ultrasound
by Dr. Christian Friedrich Stoll
When investigating infertility, checking the patency of the fallopian tubes plays a crucial role.
If one or both fallopian tubes are blocked, pregnancy cannot occur, even if all other findings in both the man and woman are normal, as the egg and sperm cannot meet.
Before this question can be addressed, it is recommended to first check the man's sperm quality through a semen analysis (spermiogram).
A fallopian tube patency test only makes sense if the man's sperm quality is adequate.
Once this is confirmed, the examination can be planned. It usually takes place after menstruation and before ovulation (day 8 to 12 of the cycle).
In the past, this examination was often performed via laparoscopy. During this procedure, other potential issues could also be diagnosed and possibly treated.
However, if the main concern is fallopian tube patency, a surgical procedure can be avoided.
The fallopian tube examination is performed by introducing a contrast agent into the uterus via a small catheter, followed by an ultrasound scan.
The procedure takes only 5 minutes, and the results are available immediately.
