The penis can be buried in the fat pad that sits in front of the pubic bone, and it can remain hidden as boys go through adolescence. What is called a “hidden penis” can be a combination of being prepubertal (so the penis has not begun to grow), being overweight (so the fat pad is significant), and in some cases an anatomical condition in which the soft tissue below the skin of the penis doesn’t adhere well to the Buck’s fascia, the thick covering that surrounds the penile nerves and arteries. This fixation problem can yield what [Dr. Aseem Shukla, a pediatric urologist at Children’s Hospital of Philadelphia and associate professor of urology at the Perelman School of Medicine at the University of Pennsylvania] described as a “slidey” penis, in which the actual shaft retreats and only the skin, or the foreskin, in an uncircumcised boy, is clearly apparent....
Dr. Shukla said that he tries to reassure preadolescents that if they lose some weight and still feel that there is a problem when they reach puberty, they can come back to address it. “I push down and I show them the length and width,” Dr. Shukla said.
