血清FSH是判断睾丸生精功能的重要实验室指标之一。本实验结果发现 :当FSH大于正常值上限 1.5倍时 ,临床上多数患者表现为无精子 ,部分患者仅 1～ 2个精子 /HP ,睾丸基本丧失生精功能 ,处于早期衰竭状态 ,且这一结果是不可逆的。当FSH大于正常值上限 2倍时 ,曲细精管闭锁 ,间质纤维化 ,睾丸容积开始缩小 ,无生精功能。同时患者性欲下降 ,出现高促性腺激素性性腺功能低下症。
Serum FSH is one of the important laboratory indicators to determine the function of testicular spermatogenesis. The results of this experiment: When the FSH is greater than the upper limit of 1.5 times the normal, most patients in clinical manifestations of azoospermia, some patients only 1 or 2 sperm / HP, testicular basic loss of spermatogenesis, in early failure state, and this The result is irreversible. When the FSH is greater than 2 times the upper limit of normal, tracheal atresia, interstitial fibrosis, testicular volume began to shrink, no spermatogenesis. At the same time, patients with decreased libido, high gonadotropin hypogonadism.
