The glandular structure of the
testis consists of numerous lobules.
Their number, in a single testis, is estimated by Berres at 250, and by Krause at 400.
Anatomic studies have demonstrated figures of 250–290 for the same.
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
The mediastinum testis is a network of fibrous connective tissue that extends from the top to near the bottom of each testis. It is wider above than below.
Numerous imperfect septa are given off from its front and sides, which radiate toward the s ...
.
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
tubuli seminiferi
Seminiferous tubules are located within the testes, and are the specific location of meiosis, and the subsequent creation of male gametes, namely spermatozoa. Structure
The epithelium of the tubule consists of a type of sustentacular cells known ...
