Ureter The prostatic utricle opens into it in the midline and the two ejaculatory ducts open just distal to the utricle. During ejaculation, wavelike involuntary muscle contractions push the sperm out of the vas deferens and into the ejaculatory ducts via a process called peristalsis. The L-ED and left VA (L-VA) showed full dilated changes. The ejaculatory ducts are 2 narrow tubes about 1 cm long. They pass through the prostate, and open into the urethra at the seminal colliculus.
