Effects of added caffeine on results following artificial insemination with fresh and refrigerated rabbit semen.
Lactating rabbits (n=1335) were artificially inseminated to study the effect of the addition of caffeine on rabbit semen stored for up to 96 h. Concentration of 0-5 mM/l were tested. Whereas a concentration of 0.2 mM/l increased spermatozoa motility, higher concentration values adversely affected reproductive parameters. Spermatozoa stored at 18 degrees C for 72-96 h did not have the capacity to react with caffeine when it was added before insemination. Caffeine did not enhance fertility or prolificacy, regardless of its ability to increase sperm motility.
