What glands associated with the human ductus deferens are missing in cat?

In humans, the ductus deferens is associated with the seminal vesicles, prostate gland, and bulbourethral glands. Cats, on the other hand, lack seminal vesicles and bulbourethral glands.

The seminal vesicles are responsible for producing a significant portion of the fluid that makes up semen. The prostate gland contributes to the production of seminal fluid and also plays a role in regulating the flow of urine. The bulbourethral glands, also known as Cowper's glands, produce a clear, viscous fluid that helps to lubricate the urethra during sexual arousal and ejaculation.

In cats, the ductus deferens is associated with the epididymis, which is responsible for maturing and storing sperm. Additionally, cats have a pair of preputial glands located on either side of the penis, which secrete a waxy substance that serves as a lubricant and helps to protect the penis during mating.
