“Stereomicroscope-Aided Retrograde Flushing Technique Yields Higher Sperm Quality in Tomcats: A Potential Gold Standard for Sperm Collection in Endangered Feline Species with Small Ductus Deferens”

https://pubmed.ncbi.nlm.nih.gov/38113674

The study found that using a stereomicroscope-aided retrograde flushing technique to collect epididymal semen in tomcats results in higher sperm quality compared to the mincing technique, and has the potential to be the gold standard method for sperm collection in endangered feline species with small ductus deferens.
