Semen specimens from 134 pubertal boys were examined and compared to bone age. Normal figures for semen volume, liquefaction, sperm concentration, and morphology were observed between 15 0/12 and 16 0/12 years of bone age. The number of normally motile spermatozoa became standard at 17 0/12 years of bone age. Azoospermia was noted from 13 0/12 to 14 0/12 years of bone age, oligozoospermia from 14 0/12 to 15 0/12, asthenozoospermia from 16 0/12 to 17 0/12, and normospermia from 17 0/12 on.
对134名青春期男孩的精液样本进行了检查,并与骨龄进行了比较。在骨龄15岁零12个月至16岁零12个月之间,观察到精液量、液化、精子浓度和形态的正常数值。骨龄17岁零12个月时,正常活动精子的数量达到标准。骨龄13岁零12个月至14岁零12个月时出现无精子症,14岁零12个月至15岁零12个月时出现少精子症,16岁零12个月至17岁零12个月时出现弱精子症,17岁零12个月及以后出现正常精子症。
