Answer:Each lobule contains 1–4 seminiferous tubules and each testis may contain up to 900 of these tubules. The tubules average 50 cm in length and are tightly coiled within the testis. A typical testis contains up to 800 m of tightly coiled seminiferous tubules.

There are almost 1500 seminiferous tubules in a pair of testis with three seminiferous tubules per lobule.
- As known, each testis has nearly 250 lobules. So a pair of testis( two testes) would have 500 lobules in total.
- Each lobule has three seminiferous tubules, so 500 lobules would have 1500 seminiferous tubules in total.
- Normally, there are almost 250-290 lobules in each testis, and each testicular lobule has 1 to 4 seminiferous tubules which are highly coiled in nature.
