The Effects Of Cruising On Semen Quality

ObjectiveTo investigate the effects of cruising on semen quality.MethodsThirty fishermen's semen were tested before and after cruising.ResultsAfter cruising, some parameters were dropping, such as semen volume (P<0.05), sperm density (P<0.05), the proportion of normal sperm morpholgy, sperm motility (P<0.01), others were not significantly changed , such as sperm liquefacion time (P>0.05), PH(P>0.05), compared with before cruising. The percentage of grade(a) sperm and grade (a+b)sperm were significantly lower after cruising than before cruising(P<0.05). The level of mercury element in semen was significantly higher after cruising(P<0.05)while other heavy metals such as Zinc, copper, lead and cadmium elements were not significantly changed(P>0.05).ConclusionIn comparison with before cruising, semen quality after cruising is decline.
