The age and health condition at the time birth were evaluated in fathers of males suffering of sterility. Of 500 of them 4% presented no complaints while the rest suffered different diseases. Of 160 fathers of the second group referred for sterile marriage with normozoospermia 90% were healthy while the remaining showed diseases of circulatory and nervous systems. Of 40 patients whose fathers were 18-25 years during birth of their sterile sons, azoospermia was revealed in 12.5%, oligozoospermia of grade III--in 42.4% and correspondingly 25-40 years--in 5.1% and 12%; 40-50 years--in 13.1% and 45.3%; over 50 years--in 27.9% and 64.5%. Consequently, the age and health conditions of the fathers during their birth may be risk factors of sterility of their sons.
对不育男性的父亲出生时的年龄和健康状况进行了评估。在500名此类父亲中，4%没有任何不适，其余的患有不同疾病。在第二组160名因不育婚姻前来就诊且精子正常的父亲中，90%身体健康，其余的患有循环系统和神经系统疾病。在40名不育儿子出生时其父亲年龄在18 - 25岁的患者中，无精子症的发生率为12.5%，III级少精子症的发生率为42.4%；相应地，父亲年龄在25 - 40岁的患者中，无精子症和少精子症的发生率分别为5.1%和12%；父亲年龄在40 - 50岁的患者中，发生率分别为13.1%和45.3%；父亲年龄超过50岁的患者中，发生率分别为27.9%和64.5%。因此，父亲出生时的年龄和健康状况可能是其儿子不育的风险因素。
