Which structure is part of the male reproductive system?

The prostate is a critical structure in the male reproductive system. It is a gland that surrounds the urethra and is responsible for producing a significant portion of the seminal fluid, which nourishes and helps transport sperm during ejaculation. This makes the prostate vital for male reproductive health and functionality.

In contrast, the vagina, cervix, and ovaries are all components of the female reproductive system. The vagina is the muscular canal leading to the external genitalia; the cervix is the lower part of the uterus that opens into the vagina; and the ovaries are the female reproductive organs that produce eggs and hormones. The distinction between these systems is essential for understanding the anatomy and functioning of human reproduction, highlighting the role of the prostate specifically in male reproductive physiology.
