Hypothesis
Can testicular blood flow measured by Doppler ultrasonography help determine fertility in camelids?
Conclusion
The study found that fertile male camelids have higher testicular blood flow compared to infertile males.
Supporting Evidence
- Fertile males had a higher peak systolic velocity in the supratesticular arteries compared to infertile males.
- End diastolic velocity was also higher in fertile males in the supratesticular arteries.
- Resistance index did not significantly differ between fertile and infertile males.
Takeaway
This study shows that we can check how well blood flows in the testicles of male llamas and alpacas to see if they can have babies.
Methodology
The study used color pulsed-wave Doppler ultrasonography to measure blood flow in the testicular arteries of 14 camelids, comparing fertile and infertile males.
Limitations
The study was limited by the inability to consistently measure blood flow in smaller intratesticular vessels.
Participant Demographics
The study included 14 camelids, with 7 being fertile and 7 being infertile.
