The Eiffel Tower sign represents the junction of which two structures?

The Eiffel Tower sign reflects the junction where the ejaculatory ducts drain into the urethra within the prostate. Each ejaculatory duct carries fluid from the seminal vesicles and they converge as they approach the prostatic urethra, near the verumontanum. On color Doppler this convergence appears as two bright jets entering the urethral lumen, creating a silhouette reminiscent of the Eiffel Tower. This makes the junction specifically the connection between the ejaculatory ducts and the urethra, not the other structures listed.
