Sometimes women think that the answer to getting pregnant is to proceed quickly to in vitro fertilizaiton or IVF. But there may be steps that you have not yet tried . Open fallopian tubes are critically important to getting pregnant without IVF. We think of the hysterosalpingogram test as just a way to determine if they are open, or closed. In the distant past we used to use air testing, then x-ray testing, and now we use ultrasonography testing. Ultrasound testing is usually with saline, and now we have a device to use air bubbles. The ultrasound test is safer from the respect of no radiation exposure, but the exposure levels are low. Now a new study that looked at x-ray technique with oil found that an extra 10% of women got pregnant with oil based fluid as the medium over not using oil. It is very simple to have a repeat check of your fallopian tubes before trying IVF. The Australia group that looked at this has decided that this is a new alternative for women not ready for IVF instead of giving up.
