Description: The ejaculatory ducts arise from the junction of the duct from the seminal vesicle and the ampulla of the ductus deferens. The urethra is the duct shared by the reproductive and urinary systems. Both semen and urine pass through it. It passes through the prostate gland (prostatic urethra), deep muscles of the perineum (intermediate or membranous urethra) and the penis (spongy urethra).
