It is located in the seminiferous tubules of the testis.

However, most fish do not possess seminiferous tubules.

Within the testes are coiled masses of tubes called seminiferous tubules.

In the male, they become seminiferous tubules.

Spermatozoa develop in the seminiferous tubules of the testes.

Even larger change can be seen in number of seminiferous tubules produced by males on different age stages:

These are called the seminiferous tubules.

Germinal epithelium is also known as the wall of the seminiferous tubule within the testes.

The inner part of the testicles have many small tubes called seminiferous tubules which are coiled (or twisted around).

In the testis, a network of tubules fuse to create the seminiferous tubules.

"Ebner's reticulum": A network of nucleated cells in the seminiferous tubules.

It describes a condition of the testes in which only Sertoli cells line the seminiferous tubules.

Each lobule contains the seminiferous tubules, extending from the base where they end blindly, towards the apex.

It is secreted from the Sertoli cells, located in the seminiferous tubules inside the testes.

The blood-testis barrier is a physical barrier between the blood vessels and the seminiferous tubules of the animal testes.

The barrier also prevents passage of cytotoxic agents (bodies or substances that are toxic to cells) into the seminiferous tubules.

Testicular seminoma originates in the germinal epithelium of the seminiferous tubules.
