Moving inward, the next section is the central zone which contains about 25% of the glandular tissue as well as the ejaculatory ducts that join with the prostatic urethra.

向内的一个区是中央区，腺体组织的25%和射精管位于此处；射精管在尿前列腺部走行。

When that time comes, during ejaculation, the sperm flow from the epididymis through the vas deferens, a tube that travels up behind the bladder and joins with the duct from the seminal gland to create the ejaculatory duct.

当这个时间到来时，在射精过程中，精子流过输精管，输精管是一种在膀胱后面行进的管，与精液腺的管连接，形成射精管。
