Male reproductive system,computer artwork. The urinary bladder (large,red) and ureters (brown) are seen at top right. Sperm are produced in the testes (brown,lower centre). During ejaculation the sperm passes into the vas deferens tubes (red loops) and are then mixed with fluids from the seminal vesicle (pink,behind the bladder) and the prostate gland (orange,below the bladder). The resulting mixture,known as semen,passes out of the body through the urethra in the penis (lower left). Erectile tissue in the penis fills with blood to hold it erect | |
