title: The relationship between the prevalence of uterine lesions and the use of medroxyprogesterone acetate for canine population control.
abstract: The prevalence of uterine disease was established during desexing of 175 bitches in the Torres Strait and Cape York, 42 of which had been treated with injectable medroxyprogesterone acetate (MPA) for oestrus postponement. The prevalence of uterine lesions was 45% for treated bitches, 5% for untreated bitches, and 14.9% for the sample population. A highly significant relationship (P < 0.01) between MPA treatment and uterine lesions was established. A significant association (P < 0.05) between age (> 2 years old) and uterine lesions was found, most likely attributable to a significantly higher proportion (P < 0.01) of MPA-treated bitches in the older population. There was no significant difference in the effect of MPA on the prevalence of uterine lesions between older and younger bitches. There was no effect of parity on the prevalence of uterine lesions.
