Human seminiferous tubules, light micrographs

---

Human testicle, light micrographs. The bottom micrograph shows seminiferous tubules. The development of spermatogenesis is asynchronous among seminiferous tubules and even within zones of a single seminiferous tubule. For this reason, in histological sections of the testis, seminiferous tubules can be seen in different phases of spermatogenesis. In the top micrograph, these different phases have been marked with different colours. Among the tubules are Leydig cells (pink).
