No. Muscles at the base of the bladder contract in order to close off the passageway from the bladder into the urethra, the tube through which urine and semen leave the body.

Where does secretion from the prostate gland deposited?
The fluid secreted from the prostate mixes with semen and comes out during ejaculation. The fluid helps the sperm move through the semen. The fluid from the prostate also comes out during a prostate massage or prostate milking. In both cases the fluid comes out through the urethra in the penis.
What is the function of the urethra in a cat?
The prostatic portion of the urethra collects seminal fluids from the prostate during ejaculation as well as providing a duct through which urine and semen can be eliminated from the body.
How might enlargement of the prostate interfere with the urination or reproductive ability of the male?
Since the urethra passes through the prostate, when the prostate enlarges it presses on the urethra and causes problems with urination. Including the inability to completely empty the bladder, increased urgency, and difficulty starting the stream. Men might experience difficulty during intercourse because of lack of libido and painful ejaculation in addition to the pain during urination. Avoiding prostate problems might involve taking supplements.
What is ejaculatory duct?
Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. They pass through the prostate, and empty into the urethra at the Colliculus seminalis. During ejaculation, semen passes through the ducts and exits the body via the penis.
Where is semen pumped from during ejaculation?
Additional stimulation leads to ejaculation, where semen is pumped out of the urethra.
What happens to the bladder and urethra during an erection?
Nothing. The bladder is essentially a bag which stores urine, it is fed by the two kidneys and it drains out along the urethra, which passes through the prostate gland, then along the length of the penis and out through the small opening in its tip. During and ejaculation sperm travels from the testes along a tube called the vas deferens until it reaches the prostate gland, here the vas deferens connects with the urethra. Put simply the prostate gland acts rather like the points system on a railway track. When the penis is soft the prostate allows liquid from the bladder to pass along the urethra and out of the penis, when the penis is erect the prostate effectively stops the flow of urine and instead allows the flow of semen into the urethra and along the penis. This mechanism prevents the two fluids from mixing, this is necessary as urine is quite effective as a spermicide.
What is prostate secretion?
Prostate secretion is called semen. It is a fluid with a milky appearance and helps to nourish and carry the sperm via penis (from testicles) during ejaculation. Prostatic secretion actually mixes with semen. The secretion liquefies the semen to allow it move through the penis during ejaculation.
What is the medical term meaning benign enlargement of the prostate?
The prostate is male reproductive gland that produces the urine fluid during ejaculation. The prostate surrounds the urethra. It's the tube through which urine passes out of the body. An enlarged prostate means the size of the gland has increased. It happens to almost all men as they get older. For treatment there are prostate health supplements that might help urinary flow and function and prostate function.
Why do you ejaculate during sex?
Ejaculation usually occurs during penile stimulation, and most frequently during orgasm. It is how the male body passes sperm from through the urethra for reproductive purposes.
What surrounds the urethra at the base of the bladder producing milky alkaline fluid?
The paired BULBOURETHRAL GLANDS (COWPER'S GLANDS) are tiny pea-sized glands located inferior to the prostate gland, on each side of the urethra. They produce a thick, clear mucus which is released prior to ejaculation when a male first becomes sexually aroused. The secretion is alkaline, so it neutralizes traces of acidic urine in the urethra. It also serves as a lubricant during sexual intercourse.
How might enlargement of the prostate gland interfere with urination or the reproductivity ability of the male?
As the prostate enlarges, the layer of tissue surrounding it stops it from expanding, causing the gland to press against the urethra like a clamp on a garden hose. The bladder wall becomes thicker and irritable. The bladder begins to contract even when it contains small amounts of urine, causing more frequent urination.
When does a man release Cowper's fluid?
Cowper's fluid, also known as pre-ejaculate, is typically released from the Cowper's gland (located near the urethra) during sexual arousal before ejaculation. This fluid can help to lubricate the urethra and neutralize any residual acidity in the urethra, preparing it for the passage of sperm during ejaculation.
