Circumcision Pros and Cons

In 1975, the American Academy ofPediatrics(AAP) stated in no uncertain terms that "there is no absolute medical indication for routine circumcision of the newborn." In 1983, the AAP and the American College of Obstetricians and Gynecologists (ACOG) restated this position. In 1999, in 2005, and again in 2012, the AAP again restated this position of equivocation.

Currently, the practice of newborn circumcision is very common. It has been estimated that a majority of males in the United States are circumcised. This number varies depending upon ethnicity and religious affiliation.

关于新生儿包皮环切,大多数医生day agree with the practice of informing parents of the risks and benefits of the procedure in an unbiased manner. Recently, however, several large studies revealed a large decrease inHIVtransmission in circumcised males compared to uncircumcised males. This finding did not impact the equivocal stance taken by these physician organizations, and they still recommend giving parents the ability to choose whether or not to circumcise their infant based on preference and religious beliefs.

The penis is a cylindrical shaft with a rounded tip. The rounded tip is called the glans. There is a groove (termed the coronal sulcus) between the shaft and the glans of the penis. The fold of skin that covers the glans is the foreskin (the prepuce).

A retractable foreskin is one that can be pulled back behind the groove of the coronal sulcus to expose the glans.

Newborn circumcision consists of removal of the foreskin -- theforeskin is resected to near the coronal sulcus -- inthe newborn period (before the age of 2 months).

Incidentally, the Latincircummeans around (or about). Circumcision is a cutting around.

What is the status of the foreskin at birth?

Few boys are born with a retractable foreskin. This reflects the fact that the tissue development of the foreskin is usually not complete at birth.

The foreskin is thus not fully separable from the glans in most newborn boys. By 1 year of age, the foreskin can be retracted in about half of boys, and by 3 years, the foreskin can be retracted in a majority of uncircumcised boys.

What does this have to do with circumcision?

It means that the inability to retract the foreskin at birth and in infancy is normal and does not constitute a medical reason for a circumcision.

Phimosisis a medical indication for circumcision. It is defined as "stenosis of the preputial ring with resultant inability to retract a fully differentiated foreskin." In other words, phimosis is present if the foreskin cannot be retracted at an age when it should normally be retractable.

What is the treatment for phimosis?

Phimosis can be treated by circumcision or by surgical enlargement of the phimotic ring, the ring of tissue causing the phimosis.

Paraphimosis occurs when the foreskin, once retracted, cannot return to its original location. The foreskin is trapped behind the groove of the coronal sulcus. Paraphimosis causes blood to pool in the veins behind the entrapment, which induces swelling. The swelling leads to severepainin the penis and makes it impossible to return the foreskin manually to its original location.

What is the treatment for paraphimosis?

The foreskin, after lubrication, can sometimes be reduced. However, this works only if the paraphimosis is discovered very early. Because of thepain, the child has to have a short-acting general anesthetic or heavy sedation for the treatment. Paraphimosis may be treated by circumcision.

Balanitisis inflammation of the glans, while posthitis is inflammation of the foreskin.Balanitisand posthitis generally occur together as balanoposthitis: inflammation of both the glans and foreskin of the penis.

What if an uncircumcised boy has phimosis, paraphimosis, or balanoposthitis?

Boys who are not circumcised as newborns may later have circumcision for the treatment of phimosis, paraphimosis, or balanoposthitis. When done after the newborn period, circumcision is considerably more complicated.

Meatitis is inflammation of the opening (the meatus) of the penis. This opening is formally called the external urethral meatus.

circumcisio之间的关系是什么n and meatitis?

Meatitis is more common in boys who have been circumcised. This stands to reason since, in circumcised boys the urethral meatus is more exposed and likely to be chafed or irritated than in boys who were not circumcised. There is no evidence that meatitis leads to narrowing (stenosis) of the urethral meatus or to other serious problems.

• The circumcised penis is generally easier to keep clean.
• An uncircumcised boy should be taught to clean his penis with care.
• 轻轻清洗阴茎是通过,不是forcibly, retracting the foreskin.
• The foreskin should be retracted only to the point where resistance is met.
• Full retraction of the foreskin may not be possible until the boy is 3 years old or older.

The incidence ofurinary tract infectionsin male infants appears to be lower when circumcision is done in the newborn period. It was first reported in 1982 that urinary tract infections (UTIs) are more common among infant males than they are in infant females (this switches later on in life). In this study, it was revealed that about 95% of the infected infant boys had not been circumcised. This risk is especially significant in infants less than 1 year of age. Many studies have shown that uncircumcised infants have a tenfold increased risk of developing aUTIwhen compared to circumcised infants.

What might this relationship between circumcision and urinary tract infections mean?

Circumcision prevents the growth of bacteria under the foreskin, and this, in turn, protects male infants againsturinary tract infection. The high incidence of urinary tract infections in uncircumcised boys has also been found to be accompanied by an increased incidence of other significant infections such asbacteremia(bacterial infection of the bloodstream) andmeningitis(infection of the covering of the brain). The protective effect of circumcision may thus extend to a number of infectious diseases.

There is a higher risk ofgonorrheaand inflammation of the urethra (the tube that carries the urine from the bladder outside) in uncircumcised men. It has also been reported that other sexually transmitted diseases (such aschancroid,syphilis,human papillomavirus, andherpes simplex virus type 2infection) are more frequent in uncircumcised men. As mentioned above, most recently three large studies performed in Africa documented that circumcision was protective with respect to the acquisition ofHIVinfection as compared to those uncircumcised subjects.

What might this connection between circumcision and sexually transmitted diseases mean?

Circumcision prevents the growth under the foreskin of the agents that cause sexually transmitted diseases. Removal of the foreskin may provide some measure of protection from these diseases to males and their mates.

There is a strong connection between sexually transmitted diseases andcervical cancer. Human papillomavirus types 16 and 18 (as well as other less commonHPVtypes) are causes ofprecancerouschanges in the cervix andcervical cancer.

The strongest predisposing factors in cervicalcancerare a history of intercourse at an early age and multiple sexual partners. AnHPV vaccineis now available and recommended for all girls and boys, and when given before the first sexual encounter, it has been shown to be protective against the most commonHPVtypes associated withmalignancy. Thevaccinepresumably prevents cervicalcancerassociated with these specific infections but is unable to preventcancersarising from infections with less common HPV types not contained in the vaccine. Therefore, routine screening for precancerous changes in the cervix is still recommended.

What might this relationship between lack of circumcision and cervical cancer mean?

Circumcision may partially protect the mate from cancer of the cervix by removing the foreskin which harbors sexually transmittedviruses(HPVs) that promote this common form of female cancer.

• The predicted lifetime risk of cancer of the penis in an uncircumcised man is one in 600 in the United States.
• Cancer of the penis carries a death (mortality) rate as high as 25%.
• This cancer occurs almost exclusively in uncircumcised men. In five major research studies, no man who had been circumcised as a newborn developed penile cancer.
• Human papillomavirus types 16 and 18, which are sexually transmitted, are involved in cancer of the penis.
• 这就是为什么常规疫苗接种对nst HPV is recommended for both boys and girls.
