Transcervical tubal embryo-stage transfer (TC-TEST).
Ultrasound-guided transcervical tubal cannulation (TC-TEST) was used to replace embryos to the fallopian tubes in 17 women whose fallopian tubes were inaccessible by the abdominal route but where at least one tube was shown to be freely patent on a preliminary hysterosalpingogram investigation. In two further cases, the fallopian tubes proved impossible to cannulate, and along with two instances where difficulty was experienced, a common underlying feature was an arcuate or septate configuration of the uterus. Three pregnancies ensued (17%) in cases where the procedure was free of difficulty and the transfers were demonstrably intratubal: two went to term and the third resulted in an ectopic pregnancy. The procedure has so far not shown a benefit over conventional IVF-ET and probably should be avoided in women with any type of tubal disorder.
