Anatomy

They differ in size according to their position, those in the middle of the gland being larger and longer.

The lobules are conical in shape, the base being directed toward the circumference of the organ, the apex toward the mediastinum testis.

Each lobule is contained in one of the intervals between the fibrous septa which extend between the mediastinum testis and the tunica albuginea, and consists of from one to three, or more, minute convoluted tubes, the seminiferous tubules (tubuli seminiferi).

Each tubule extends from the base of the lobule where the tubule ends blindly towards the apex of the lobule.[4][verification needed][better source needed]
