Utero-tubal embryo transfer uses the utero-tubal junction as a barrier to prevent the embryo outflow that may occur when performing uterine transfer. Vasectomized males are required to obtain pseudopregnant recipients for embryo transfer. Both techniques are discussed.

We present a protocol to efficiently evaluate aneurysm perfusion and vessel patency of sidewall aneurysm in rats and rabbits, using fluorescein-based fluorescence video angiography (FVA). With a positive predictive value of 92.6%, it is a simple but very effective and economical method with no special equipment required.
FAQs
Clinicians interpret the movement of contrast medium, saline, or dye through the fallopian tubes as evidence about whether the passageway is sufficiently open. The observation connects an anatomical finding with reproductive function because sperm movement, fertilization, and transport of a fertilized egg all depend on tubal passage. Restricted or absent passage indicates a tubal abnormality requiring further clinical consideration.
Infection, inflammation, endometriosis, and previous surgery can contribute to tubal blockage or other abnormalities. These conditions matter because impaired tubal passage can interfere with the sequence of sperm movement, fertilization, and transport toward the uterus. Identifying a possible tubal contribution helps clinicians place fertility difficulties in a broader medical context rather than evaluating reproductive function in isolation.
Tubal abnormalities are clinically important beyond their possible contribution to infertility because they may increase the risk of an ectopic pregnancy. Testing can therefore provide information about the condition of the tubes, not only whether they appear sufficiently open for reproductive transport. This added context may influence how clinicians interpret fertility findings and plan subsequent evaluation or treatment.
A clinician introduces a contrast medium, saline, or dye and then observes whether it passes through the fallopian tubes. The selected visualization approach may use radiography, ultrasound, or laparoscopy. Together, the introduced material and imaging or direct visualization provide the basis for identifying passage or tubal abnormalities during a fertility evaluation.
Clinicians use this assessment when investigating infertility to determine whether tubal factors may be contributing to difficulty conceiving. The findings add anatomical information to the broader evaluation and can help distinguish a possible passage problem from other causes that may require consideration. Results may also help guide decisions about assisted reproductive treatment.
Tubal findings can contribute to decisions about whether assisted reproductive treatment should be considered and how fertility care should proceed. Evidence of blockage or abnormality identifies a tubal factor that may affect natural reproductive transport, while the test also documents information relevant to treatment planning. Its value lies in connecting diagnostic findings with individualized clinical decision-making.
