Studies on the sperm reservoir of the pig oviduct [PDF]
, 2003 During sperm transport in the female pig a proportion of spermatozoa are arrested, often for 24 h or more, in a particular segment of the utero-tubal junction (UTJ) and the adjacent tubal isthmus, where a sperm reservoir (SR) is built up.

Unilateral ductus deferens aplasia with terminal cystic dilation in a Bernese mountain dog
Veterinary Record Case Reports, Volume 14, Issue 3, August 2026.Abstract An incidental caudal abdominal mass was discovered in a 5‐year‐old, male, entire Bernese mountain dog. Investigations showed a terminal cystic dilation of the left ductus deferens. Castration, along with surgical resection of the mass, was performed, and histopathology of the mass and ductus deferens was consistent with segmental aplasia of ...

Andrology, Volume 14, Issue 5, Page 1249-1260, July 2026.ABSTRACT Background Extracellular vesicles (EVs) produced by accessory sex glands play a key role in sperm functionality, influencing motility, viability, acrosome integrity, metabolic activity, and capacitation. Most studies on the effects of EVs on spermatozoa have focused on ejaculated spermatozoa, which have already been exposed to their own native

Sperm Sexing in Selected Animals and Humans: Methods, Applications, and Future Prospects
Andrology, Volume 14, Issue 5, Page 1089-1101, July 2026.ABSTRACT Background Sperm sexing is a technique that enables the selection of offspring sex by sorting spermatozoa based on their sex chromosomes. This technology has gained increasing attention due to its potential applications in both animal breeding and human‐assisted reproduction.
