SALVIANO, M.B. et al. Integrity of membrane and sperm chromatin in bucks with and without scrotal bipartition. Arch. zootec. [online]. 2011, vol.60, n.232, pp.1319-1322. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922011000400047.

Some bucks from arid and semi-arid regions have scrotal bipartition. It has been speculated that this feature improves semen quality by the regulation of intratesticular temperature. This work evaluated the quality of semen and spermatozoa of four bucks without, and three with scrotum bipartition, through conventional analyses, hypoosmotic swelling test and acridine orange. Results shows better physical and morphological characteristics in addiction better quality of plasma membrane for animals with scrotal bipartition, which suggests better adaptation to arid and semiarid regions in these animals.
