What is congenital bilateral absence of the vas deferens?
Congenital bilateral absence of the vas deferens occurs in males when the tubes that carry sperm out of the testes (the vas deferens) fail to develop properly.
vas deferens: tube through which sperm travel from the testes to the prostate prior to ejaculation
vascular: relating to a blood vessel
vascular pedicle: a stalk through which the prostate receives and drains blood.
Vas deferens
One of two tubes that carry sperm from the testicles to the penis. When a man has a vasectomy, it is the vas deferens that is severed.
Vas Deferens
The vas deferens is a 45 cm long muscular tube that transports sperm to the ejaculatory ducts.

vas deferens: Also referred to as vas. The cordlike structure that carries sperm from the testicle to the ejaculatory duct, whicn in turn carries it to the urethra.
Vas deferens
The long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the urinary bladder. The vas deferens transports mature sperm to the urethra in preparation for ejaculation.

vasectomy - a surgical procedure performed to make a man sterile, or unable to father a child. It is a permanent male birth control measure, and a means of contraception used in many parts of the world.
The vas deferens carry the sperm produced in your testicles to your urethra, which is the tube inside your penis. Vasectomy is usually done by a surgeon in the office or in an outpatient setting using local anesthesia.
The vas deferens can be seen quite easily under the cut skin. It is cut, and the two ends are tied. The small cuts to the skin are then stitched or stuck back together with tape. Dissolvable stitches are used if the cut is stitched.

Some men lack the tube that carries sperm (vas deferens) from the testicle out to the opening in the penis.
No semen (ejaculate). The absence of ejaculate may occur in men with spinal cord injuries or diseases.
A similar though perhaps a slower effect is produced when the duct of the testis, the vas deferens, is divided on each side of the body.
Only the area around the vas deferens (vas or sperm duct) becomes numb. The injection of the local anesthetic will sting briefly.
Once the area is numb, some men will still feel a pulling and/or cramping sensation during the procedure.
The vas deferens will be pulled through the openings. The tubes will then be cut. A small piece of the tubes may also be removed. The ends of the tube will be sealed off with stitches, clips, or an electrical pulse.
(1) Congenital absence of the vas deferens (CAVD)
CAVD is an uncommon obstructive post testicular lesion that results in a complete absence of sperm (azoospermia). Most men with CAVD have an intact upper one third to two thirds of the epididymis.
The sperm then move to the vas deferens, or sperm duct. The seminal vesicles and prostate gland produce a whitish fluid called seminal fluid, which mixes with sperm to form semen when a male is sexually stimulated.
Absent sex organ structures, such as the vas deferens and seminal vesicles in males, and the uterus in females.
Absent rectum and anus (anorectal atresia).
Gap in the oesophagus (oesophageal atresia).
Malformations of the legs.
Each vas deferens is located by touch.
A local anesthetic Opens New Window is injected into the area.
Your doctor makes one or two small openings in your scrotum. Through an opening, the two vas deferens tubes are cut.
In men, the vas deferens (a tube that carries sperm) on one side may be damaged. This could make a man sterile if the vas deferens on the other side is not normal.

During male orgasm, sperm is released from each testicle, and travels along the tube called the vas deferens to the prostate where it mixes with semen.
Your surgeon will find the vas deferens by feeling your scrotum and then give you a shot of the anesthesia into this area to numb it
Your surgeon will then make a tiny hole in the skin of your scrotum and seal off the vas deferens.
During ejaculation, sperm travels from the testicle through tubes called the vas deferens. The vas deferens run behind the bladder and enter into the prostate gland.
A doctor may use a local anesthetic to desensitize the scrotum, then make two small incisions to reach the vas deferens - the tube which tranmits sperm from the testicles.
The scrotum is numbed with an anesthetic, so the doctor can make a small incision to access the vas deferens, the tubes through which sperm travels from the testicle to the penis. The doctor then seals, ties or cuts the vas deferens.
The epididymides should be examined for the presence of the entire gland, continuity with the vas deferens, induration, or tenderness.
During sexual climax, the sperm move from the epididymis through a tube called the vas deferens and mix with other components of semen to form the ejaculate.
congenital bilateral absence of the vas deferens (CBAVD) in males
As stated above, the symptoms of CF differ for each person. Infants born with CF usually show symptoms within the first year.
The vas deferens (the tubes that carry sperm) are cut and sealed.
A vasectomy is performed safely in a doctorâ ' s office using a local anesthetic to numb the area.
After numbing the scrotum and making one or two small openings in it, the surgeon cuts each vas deferens (possibly removing a small section of it as well).

During this technique, a non-toxic synthetic chemical is injected into the vas deferens. The chemical reacts and blocks the vas deferens. The chemical also kills sperm when they come into contact with it.
Some men have congenital (present at birth) absence of the vas deferens on one or both sides. The vas deferens is the tube that conducts the testicular component of semen to the urethra, which then carries semen through the penis to the outside world.

Basically, it involves the surgeon cutting and then sealing the ‘vas deferens' (tubes) which prevents sperm from entering semen that is ejaculated during sexual intercourse. This results in infertility and an inability to father a child.
Men who have CF are infertile because they're born without a vas deferens. The vas deferens is a tube that delivers sperm from the testes to the penis.
Vasotomy
Incision or opening of the vas deferens.
Vasovasostomy

Ejaculatory duct: A canal in the male formed by union of the vas deferens and the duct from the seminal vesicle. The ejaculatory duct passes through the prostate. Semen passes through them at the time of ejaculation.
Antibodies that target sperm and weaken or disable them usually occur after surgical blockage of part of the vas deferens for male sterilization (vasectomy). Presence of these antibodies may complicate the reversal of a vasectomy.
They are attached to the ejaculatory duct in the lower pelvis by cords called spermatic cords, which contain the vas deferens, the narrow tube through which the sperm moves out of the testis.
Sterilization, male surgical: Male surgical sterilization is done by vasectomy which involves sealing, tying or cutting a man's vas deferens, the tube which otherwise would carry the sperm from the testicle to the penis.
Epididymitis can also be caused by injury or infection of the scrotum or by irritation from urine that has accumulated in the vas deferens (the duct through which sperm travels after leaving the epididymis).
