01 / Location & anatomical relationships
Below the bladder, surrounding the first part of the urethra in people who have it.
02 / Structure & organization
The prostate surrounds the proximal male urethra below the bladder. Glandular tissue and fibromuscular stroma form distinct anatomical zones. Secretions enter the urethra through prostatic ducts and contribute to seminal fluid.
03 / Function
It makes fluid that becomes part of semen after puberty.
04 / Mechanism
This gland makes some of the fluid that combines with sperm and other fluids to form semen. Its muscles help move that fluid during ejaculation after puberty. Its location links it closely to the urinary passage.
Working together: reproductive system
Bodies develop in different ways. During puberty, hormones help reproductive organs mature. A pregnancy can begin when a sperm cell fertilizes an egg cell, and development continues in the uterus.

Connect structure with function
Its close relationship to the urethra explains why changes in prostate size can influence urinary flow. The prostate produces fluid, not sperm cells.
Check your understanding
Locate the prostate in relation to its neighbors. Explain how the structural features described above support its function, then distinguish it from a nearby structure with a different role.
