What is the role of the seminiferous tubules?

Seminiferous tubules are where spermatogenesis, the production of sperm, occurs.

What cells in the testis produce testosterone?

Leydig cells in the testis produce testosterone.

What is the epididymis?

The epididymis is a long, coiled tube that stores and matures sperm cells.

Which part of the testis connects to the vas deferens?

The epididymis connects the testis to the vas deferens.

What structure separates the lobules within the testis?

The septa, septal tissue, separate the lobules within the testis.

How are spermatogonia involved in sperm production?

Spermatogonia are the stem cells that divide and differentiate to form sperm cells in the seminiferous tubules.

What is the rete testis?

The rete testis is a network of ducts that transport sperm from the seminiferous tubules to the epididymis.

What role do Sertoli cells play in the testes?

Sertoli cells support and nourish the developing sperm cells within the seminiferous tubules.

What is spermatogenesis?

Spermatogenesis is the process of sperm cell development.

How many lobules does each testis typically contain?

Each testis typically contains about 250 lobules.

What is the mediastinum testis?

The mediastinum testis is a thickened tissue at the posterior of the testis, forming a support for the rete testis.

What distinguishes the testes from other gonadal structures?

The testes are male gonadal structures known for external androgen production and sperm development.

What is the pampiniform plexus?

The pampiniform plexus is a network of veins that help cool the arterial blood before it reaches the testis.
