间质细胞-曲细精管在睾丸内可能双向沟通。对保持曲精管功能的间质细胞提供了必需的睾酮而曲细精管分泌物可能调节间质细胞的功能。曲细精管的分泌液同时对间质细胞功能有刺激和抑制作用。根据大鼠睾丸形态学的研究,提示曲细精管和精子生成周期时局部调节间质细胞活性。因此,位于大鼠腹部的睾丸中间质细胞功能不良是由于损伤曲细精管从而刺激作用降低所致。患有单纯支持细胞综合征的病人睾丸中生殖细胞缺少或很少。而间质组织包括间质细胞则尚未彻底研究清楚。因此,睾丸中曲细精管受到的影响是明显的。患有单纯支持细胞综合征的病人,血清中LH浓度通常是在正常范 Interstitial cells - seminiferous tubules in the testes may be two-way communication. It provides the necessary testosterone for interstitial cells that retain the function of the seminiferous tubules and the function of the seminiferous tubules secretions that regulate the interstitial cells. Seminal fluid of seminiferous tubules simultaneously stimulate and inhibit the function of interstitial cells. According to the testicular morphological studies in rats, it is suggested that the seminiferous tubules and spermatogenesis locally regulate the activity of interstitial cells. Thus, dysfunction of testicular mesenchymal cells located in the abdomen of the rat is due to a lessened stimulating effect by damaging the seminiferous tubules. Germ cells in the testes of patients with pure support cell syndrome are absent or seldom. The stromal tissue including stromal cells have not yet been thoroughly studied. Therefore, the testicular seminiferous tubules affected by the obvious. In patients with pure supportive cell syndrome, serum LH concentrations are usually normal
