The effect of the age of dogs on their ejaculate

Popis výsledku v původním jazyce

The effect of the age of dogs on quantitative and qualitative parameters of the ejaculate was explored. We evaluated 43 dogs; from each dog we collected three samples on three successive days. The dogs were divided into three age categories: 1.5--2 years; 2--3 years; and 3--5 years. The maximum ejaculate volume was collected from dogs of 2--3 years of age; the average volume of ejaculate from 3 collections was 9.1 ml. Microscopic examinations of the ejaculate of this age category of dogs showed that thehighest average sperm concentration was 153.62. 103.mm-3. In older dogs the ejaculate volume decreased considerably with increasing frequency of collections (8 ml > 5 ml > 2 ml at the 3rd collection). The amount of motile sperm was the highest in 3 to 5-year-old dogs (76%) and was related with the highest proportion of morphologically normal sperm (66.8%). However in the 3rd collection of this age category we saw a significant (P < 0.05) increase in the amount of pathologically changed
