Abstract
This study was designed to determine possible effects of human kisspeptin-10
(KP-10) on motility spectrum of buffalo bull spermatozoa. Semen was collected
from three adult Nili-Ravi buffalo bulls twice a week for three-weeks, split
into five aliquots and diluted with different doses (0, 0.2, 2.0, 20.0 and 40.0
µM) of KP-10 in 0.1% BSA-PBS. The aliquots were incubated for 2, 6, 12 and 24
min at 37°C and evaluated through Computer-Assisted Sperm Analysis (CASA) system
for sperm motility parameters. Ethanol fixed smears were processed for
immuno-cytochemical detection of KP.
Results showed that KP-10 exposure (mostly at 20.0 and 40.0 µM) for different
incubation time-points significantly (P<0.05) improved CASA sperm motilities,
velocities, and rapid subpopulation than control. Furthermore, buffalo bull
spermatozoa showed KP-10 expression in their tail region.This study identified the stimulatory effect of human KP-10 on buffalo bull
sperm motility parameters during in vitro
incubation. Thus, human KP-10 can be potentially used to enhance quality of
buffalo bull sperm during incubation at 37°C
in vitro.
