1·Conclusion: LBP could decrease the structural damage of seminiferous tubule caused by higher temperature culture.

结论：LBP可减弱由于培养温度过高所致的曲精小管结构损伤。

2·Objective: To report 7 cases of male infertility with calcified seminiferous tubules, and discuss its pathology, imaging features, and common complications.

目的：本文报道7例睾丸精细小管钙化男性不育症患者，并结合文献对其病理、声像图特征及常见并发症进行探讨。

3·In testicle of group A, HBV DNA can be widely found during the outer compartment of seminiferous epithelium and the inner compartment of spermatogenic cells;

③在A组样本的睾丸组织中，HBV DNA分布弥散，可广泛发现于生精上皮基底室和近腔室的生精细胞上；

4·Testes from 18-day-old embryonic chickens were used to isolate seminiferous epithelial cells by sequential two-step enzyme digestion with collagenase and trypsin.

以18天鸡胚睾丸为实验材料，经胶原酶和胰蛋白酶两步酶消化法得到生精上皮细胞悬液。
