Abstract:
Objective To study the influences of the length of sexual abstinence on sperm parameters and seminal plasma biochemical indicator.Methods Sperm concentration and motility were detected by computer assisted sperm analysis(CASA).The sperm morphology was analyzed using semiautomatic sperm morphology analyzer.Seminal plasma fructose concentration,neutral a-glycosidase,zinc,and acid phosphates concentration were measured by spectrophotometer.Improved DTNB was conducted for detection of the content of seminal plasma novain.Prostatespecific antigen(PSA)was measured with commercial kit.Three groups were defined according to the days of sexual abstinence:G1(1-3 days),G2(4-5 days)and G3(＞6 days).Results Sperm concentration of G2 was significantly higher than that of G1(P＜0.01),and of G3 than that of G1 and G2(P＜0.01).Sperm motility and per centage of morphologically normal sperm of G3 were significantly lower than that of G1(P＜0.01).Seminal plasma fructose concentration of G3 was significantly lower than that of G1 and G2(P＜0.01,P＜0.05).Seminal plasma neutral a-glycosidase,carnutine,zinc concentration of G3 was significantly higher than that of G1 and G2(P＜0.01,P＜0.05).Conclusion The length of sexual abstinence can influence sperm parameters and seminal plasma biochemical indicator.
