Observations on semen quality of dogs in the tropics.
Semen was obtained from eight mongrels and 17 purebred dogs kept in a tropical climate. The mean spermatozoal output per ejaculate was 303.6 +/- 138.2 and 602.9 +/- 466.2 million, respectively. Values for individual progressive motility, live and abnormal spermatozoa were comparable with those obtained in temperate regions. The type and frequency of spermatozoal abnormalities are illustrated.
