Question

Which of the following is true with respect to the human male reproductive system?

• A. 250 testicular lobules in each testis $\to$ 1- 3 seminiferous tubules in each lobule $\to$ vas deferens
• B. 250 testicular lobules in each testis $\to$ 1-3 seminiferous tubules in each lobule $\to$ rete testis
• C. 1- 2 seminiferous tubules in each lobule $\to$ 500 testicular lobules in each testis $\to$ rete testis
• D. 1 testicular lobule in each testis $\to$ 250 seminiferous tubules in each lobule $\to$ rete testis

Answer 1

The correct option is B 250 testicular lobules in each testis $\to$ 1-3 seminiferous tubules in each lobule $\to$ rete testis

Human male reproductive system consists of 2 testes, each of which are located inside a sac-like structure called scrotum.

Each testis has about 250 compartments called testicular lobules.

Each testicular lobule contains 1- 3 seminiferous tubules, inside which the spermatogenesis occurs.

The seminiferous tubules of each testis open into a network of delicate tubules called rete testis. Rete testis opens into vasa efferentia.
