Abstract
Semen was collected from eight dogs after SC administration of 0.1 mg/kg PGF2alpha or 0.6 mL 0.9% NaCl solution 15 min prior to collection in the presence or absence of an estrous teaser bitch (switchback design; all dogs given all four treatments in random sequence). There were more spermatozoa (P = 0.02) in ejaculates collected after administration of PGF2alpha in the presence of an estrous teaser bitch ((852 ± 736) × 106, mean ± S.D.) than in ejaculates collected in saline-treated dogs in the absence of a teaser bitch ((371 ± 620) × 106). However, the number of spermatozoa in the ejaculate of dogs given PGF2alpha in the absence of a teaser bitch and in dogs given saline in the presence of a teaser bitch ((556 ± 494 and 600 ± 622) × 106, respectively) were not significantly different from each other or from the other two groups. The percentage of morphologically normal spermatozoa did not vary by treatment (P = 0.51). In conclusion, treatment with PGF2alpha and presence of a teaser bitch had an additive effect on the number of spermatozoa. This, coupled with relatively minor side-effects, suggests this is a useful technique to increase number of spermatozoa in a single canine ejaculate.
