Abstract
Summary. Each of twelve rabbits was ejaculated for 5-week periods at frequencies of: once a week (1 × F) ; four times on Friday (4 × F) ; twice on Monday, Wednesday and Friday (2 × MWF) ; and once daily except Sunday (1×M-S). Average sperm outputs/ejaculate (×106) for the four ejaculation frequencies were: 273 for 1 × F; 114, 207, 141 and 80 for first, second, third and fourth ejaculates, respectively, at 4×F; 78 and 128 for first and second ejaculates, respectively, at 2 × MWF; and 86 for 1 × M-S. Repetitive ejaculation significantly increased weekly sperm output (P<0·01). Component of variance analysis of weekly sperm output indicated that differences among bucks were magnified by the more intensive ejaculation frequencies, but not as much as average sperm output.This publication has 1 reference indexed in Scilit:
