Objective:To study the effect of smoking on the semen quality
the level of serum testosterone and L-carnitine in seminal plasma.Methods:90 men
who had the history of pregnancy individual
were divided into three groups.Semen parameters(volume
sperm density
viability
motility)
serum testosterone and L-carnitine were examined.Results:There are significant difference between A and C group about sperm density and the percentage of progressive motile spermatozoa
and between B and C group about motility
and between A and C about serum testosterone
and between A and B about the level of L-carnitine
especilly between A and C group(P<0.01).Conclusion:Heavy and long-term smoking repress the synthesis of testosterone and decrease the level of L-carnitine in seminal plasma.Cigarette smoking appears to affect seminal parameter
serum testosterone and condition of seminal plasma.Heavier and longer would be more.
