preliminary results: effect of lycopene administration on semen quality of rabbit.
a total of 18 hybrid strain martini male rabbits were randomly divided into three
experimental groups. The animals of the first and the second group drank water with
0.1 (group a) and 0.5 (group b) g/l of lycopene addition (a and b groups, respectively),
while water without any supplementation was administered to the rabbits
of the control group (C), 8 weeks treatment. semen was collected from 18 bucks
(6 animals/group) for 5 consecutive weeks. ejaculate volume was determined by
graduated test-tube and sperm concentration was calculated by neubauer chamber.
sperm motility was evaluated subjectively by a phase contrast microscope. FPm
was scored 1÷4 (low-high). sperm viability was assessed by nigrosin/eosin (n/e)
staining procedure. data reported showed that the highest level of lycopene (group
b) resulted in a significantly greater volume of ejaculate and total number of sperm
than in the control group (0.98 vs. 0.78 ml, P
