I am brushing up on my human reproduction before I teach it to the sixth from tomorrow.
Did you know that a man has 6M of tubes in each epididimus on each testicle! Bloody hell, human beings are amazing.
Did you also know that men secrete a clear fluid before they ejaculate to nutralise any urine left in the penis! Amazing stuff!
Bloody good job we don't have to think about this isn't it, or they would never get it organised!
