Dr. Greene's Answer

“It’s a boy!”

When we an initial glimpse our kids in the distribution room, their sex is among the instant things we notice. It’s also one the the an initial things we report come family and friends. In the last generation, countless of us have seen proof of our children sex top top ultrasound even before they to be born, yet still in ~ the birth, we look come see.

How disconcerting to parents when a boy’s prick seems to disappear, either at birth or quickly thereafter. The good news is the the outlook is bright. Periodically surgery is needed, sometimes clinical treatments, and often nothing in ~ all.

Any problem in i m sorry the dick is considered lacking or especially tiny is categorized as “inconspicuous penis.” within this umbrella term are several species of diagnoses, each with their certain traits and methods that treatment. These incorporate webbed penis, hidden penis, trapped penis, micropenis, and lacking penis. Such conditions are caused by a range of factors, including, but not limited to, hormone levels, circumcision, and the usage of harmful chemicals, called phthalates, present in some plastics. The variations of inconspicuous prick are outlined below, as well as information on phthalates and also how to stop them.

Webbed Penis

Webbed cock refers come an median sized cock where the skin that the scrotal sack extends part method up the obelisk of the penis. Some children are born through this condition, and others may build it due to an aggressive circumcision. In this case, adhesions type between the scrotal and penile skin as the circumcision attempts come heal. 

Webbed penis does no interfere with any kind of of the miscellaneous penile functions, and usually causes no concerns unless lot of circumcisions space performed in an effort to cut ago the skin. A webbed prick is unlikely to readjust unless surgical treatment is performed, however surgical outcomes are often highly successful

Concealed Penis

A covert penis is an typical sized dick that is covert within the pad the fat that lives over the pubic bone. The is occasionally called hidden or surprise penis. Concealed penis can happen from birth, or post-circumcision. The is fairly common in infants and toddlers, however can occasionally happen in older children or teens who space obese. 

If the penis can conveniently be exposed by tenderness pulling on it or by depressing the neighboring fat pad, then there is a great chance that will grow normally and also reveal itself over time. Sometimes surgery is necessary to correct concealed penis, but either method the outlook is quite hopeful for youngsters with this condition. 

Trapped Penis

Trapped penis refers come a penis of median size that is partly stuck in the pubic fat pad. Youngsters with this problem are not born this way, but it develops as a an outcome of circumcision. Situations that reason this include the regimen circumcision that a webbed penis, or as soon as circumcision synchronizes with significant scrotal swelling from a hydrocele or hernia. Scarring or adhesions then partially trap the dick within the pad the fat. This is one unfortunate situation that can predispose children to urinary tract infections or urinary retention. In the case of trapped penis, surgical treatment is commonly advisable in order for it to role normally.


Average prick Size — stretched Penile Length 

All that the over conditions have a dick of typical size. In identify size, the “stretched penile length” is far more important than the “relaxed length.” to evaluate cock size, stretch the prick gently and measure from the bone at the base all the means to the tip. Be certain to depress the surrounding fat pad to acquire all the way to the base. Here are the common values (Adapted native Feldman KW, blacksmith DW. Journal the Pediatrics. 1975; 86:395):

Some limited growth of the penis does occur in between 0 and also 5 year of age, and again a little amount in between 5 years and also onset that puberty. Adult size penis and testicles are typically reached around 5 years after onset puberty, however exact timing is varied. 


Also known as microphallus, micropenis advert to penis length an ext than 2.5 traditional deviations below the typical size because that age. Because that a newborn, a stretched size that is less than ¾ inch (1.9 cm) is taken into consideration micropenis. 

Cases of micropenis are thought about to have hormonal origins, although the special, of that have yet to be revealed. That is thought that a sort of hormonal imbalance occurs sometime after 14 weeks gestation, as soon as the penis has formed. Babies born with micropenis should have their hormone levels monitored, in enhancement to checking chromosomes in stimulate to evaluate for any kind of underlying hereditary syndrome. It’s also helpful to acquire an MRI to inspect hormone secreting glands. 

Often the first step in treatment might be a three month trial of testosterone supplementation. If the dick grows in an answer to testosterone, the outlook is hopeful for typical adult dick size and function. 

Even if over there is no solution to hormone treatment, some studies of micropenis have found that also if a young grows up with a little penis, many are maybe to stand to urinate, preserve normal erectile function and it is in sexually active. Their partners also report sex-related satisfaction. In the past, physicians would recommend gender reassignment surgical procedure for youngsters with micropenis that did no respond come testosterone therapy. However, this opinion has changed given that many children with micropenis can maintain healthy and balanced functionality of the penis, and also some adult who have actually received therapy for intersex conditions argue strongly against gender reassignment before the boy is old enough to choose. Penile prosthesis are available to youngsters if desired, or if peer teasing is one issue. For households considering reassignment surgery, there are a growing number of gender clinics throughout the country that can provide individualized counseling and also treatment because that families experimenting this option.

Absent Penis

Also called penile agenesis, this problem is very rare, affecting just 1 in 20 million children. 9 Typically in such cases the scrotum and also testicles form normally, however there is no penis. If your child is born through this problem it’s necessary to consult not only your pediatrician, but likewise a geneticist, endocrinologist, urologist and mental health expert. Their cumulative assessment can be advantageous in deciding what procedures to take because that the health and also well-being of your child. 

The Trouble through Phthalates 

Phthalates are artificial chemicals found in many plastics, provided to make plastics much more pliable and less brittle. When took in in the body, phthalates have the capacity to influence hormones, consisting of the increase of estrogens in the form of xenoestrogens. That well interpreted that high level of phthalates make male animals much more feminine, with transformed genitals, altered behavior, bad quality sperm, and increased infertility. But the result on human being babies has not to be well studied. However, one sobering study says that exposure come phthalates before birth may under-virilize boys, which can be seen v a shorter penis length, thinner cock width, smaller and also less unique scrotum, shorter distance between the anus and also scrotum, and greater likelihood of undescended testicles. The study was carried out by researcher from several medical schools, in conjunction with the National center for environmental Health. 

A research was done the tested the pee of pregnant females for 9 usual phthalates. The tallied quantities varied considerably from woman to woman. Next, a different collection of researchers built up measurements the 134 boys’ genitals. Babies whose mothers were in the top quartile the 4 of the different phthalates in your urine ranged from 3 to an ext than 10 times more likely to have an anogenital table of contents (AGI) shorter than expected, when compared to babies who moms were amongst the 25 percent v the lowest level of these certain phthalates. No distinctions were detected v the other 5 species of phthalates.

Phthalates are a fairly recent addition to manufacturing, brand-new to the environment within about the critical 50 years. Phthalates are found in plastic wraps, bags, medical equipment and toys, as well as other plastic products. Castle are additionally frequently used in the recipes of many personal care products, including makeup, lotions, shampoos and also soaps, and also paints and pesticides. Many organic assets will proudly state castle are totally free of phthalates. Together these chemicals are extremely common, that is wise to look for out assets that plainly say they execute not include these additives. 

Take note! The chemistry from plastics, paints, pesticides, and personal care assets are absorbed by our bodies, and can possibly alter an unborn baby’s development. Over there is still little we know around this effect on person health. Native the pee study, that clear some phthalates are an ext dangerous 보다 others for hormonal development, but it’s also possible that other phthalates affect us in means we have yet come measure. For example, we room still learning around how these and also other chemicals connect with each various other in ours bodies. However, this examine is very helpful, as it says we could find ways to prevent our current instance of increasing infertility, genital, and also gender problems.

Final Thoughts

Parental pertains to over any type of variation the inconspicuous penis are understandable. If there is any kind of question about the size and also health of a children penis, it’s essential for pediatricians to first examine and also measure, then plainly communicate to parental if the child’s dick is healthily formed and also sized. Any kind of questionable results must go to a pediatric urologist because that a setup to certain the wellness of the baby, and also monitored with continued visits as the boy grows older. In most cases, an inconspicuous cock is readily treatable. The vast bulk of youngsters with this condition go on come live happy, healthy, regular lives.
