Identify the primary organs of male external genitalia

The main organs of the male external genitalia consist of the penis and the scrotum.

The penis is a cylindrical organ made of erectile tissue, which has the ability to expand and become rigid during sexual arousal.

Describe the scrotum

The scrotum is a sac-like structure that hangs behind the penis and houses the testes, which are the male reproductive glands responsible for producing sperm and hormones like testosterone. The scrotum is instrumental in keeping the testes at the optimum temperature for sperm production, ensuring healthy sperm quality and quantity.
