Which statements are true about the male reproductive system (urethra, prostate, testes)?

What this question is really testing

You need to match each structure to its main function: the urethra is an exit tube, the prostate adds fluid to semen, and the testes are the main source of male sex hormones.

Checking each statement

• “The urethra is the tube that carries sperm from the testes to the penis”: False. Sperm travel from the testes (via the epididymis) through the vas deferens to reach the urethra.
• “The urethra is the tube through which urine and sperm flows”: True. The urethra carries urine from the bladder and semen out of the body (not usually at the same time).
• “The prostate produces liquids that help sperm survive outside the body”: True. The prostate adds an alkaline fluid to semen that helps protect sperm and improve movement.
• “The prostate makes testosterone”: False. Testosterone is produced mainly by the testes (Leydig cells), not the prostate.
• “The testes make oestrogen”: False (in standard school biology). The testes primarily make testosterone; while small amounts of oestrogen can be present in males, it is not the main function emphasized for testes.
• “The testes make testosterone”: True. This is the main male sex hormone produced by the testes.

Quick memory tip

• Testes: make sperm and testosterone.
• Vas deferens: transports sperm.
• Urethra: exit tube for urine and semen.
• Prostate: adds fluid to semen.
