the external male organ of urination and copulation.

The body of the penis consists of three cylindrical-shaped masses of erectile tissue which run the length of the penis. Two of the masses lie alongside each other and end behind the head of the penis. The third mass lies underneath them. This latter mass contains the urethra. The penis terminates in an oval or cone-shaped body, the glans penis, which contains the exterior opening of the urethra.

The glans penis is covered by a loose skin, the foreskin or prepuce, which enables it to expand freely during erection. The skin ends just behind the glans penis and folds forward to cover it. The inner surface of the foreskin contains glands that secrete a lubricating fluid called smegma which makes it easy for the penis to expand and retract past the foreskin.
buried penis concealed penis.
clubbed penis penile curvature.
concealed penis a small penis concealed beneath a fat pad or the skin of the scrotum, abdomen, or thigh; called also buried penis.
double penis diphallus.
webbed penis a penis enclosed by the skin of the scrotum.

A rare congenital anomaly in which the penis is partly or completely duplicated; may be laterally symmetric, or placed one above the other; often there are associated urogenital or other anomalies; occurs when two genital tubercles develop. May also be associated with exstrophy of the urinary bladder and splitting of the genital tubercle.

True diphallia is a rare anomaly with a wide spectrum of presentation due to associated anomalies.
The wide variability of the anatomy and the presentation in diphallia cases result in different management strategies of the pathology.

Successful surgical correction of true diphallia, scrotal duplication, and associated hypospadias.
In summary, the anatomical examination of the human cadaver described above characterizes the respective case as a complete bifid penis, a subset of human diphallia, which was accompanied by proximal penoscrotal hypospadias.
Since human diphallia is an extremely rare anatomical variation as only ~ 100 cases have been reported for over 400 years, we decided to take advantage of this unique opportunity and screen for the diphallia-associated genetic variants to gain important insights into the possible cause(s) of its formation (see Supplementary Materials for experimental details).
First, it can be characterized as a complete bifid penis which accounts for one-third of all reported and extremely rare diphallia cases [1, 2].
Our results support clinical observations pointing toward human diphallia being polygenic syndrome and provide several important insights into its etiology.
Second, the mutation in KMT2C (Table 1) could indicate the involvement of the epigenetic regulatory mechanism(s) in the above process and support an early hypothesis regarding the detrimental impact of environmental factors on the fetal caudal mass of mesoderm leading to diphallia development [3].
Fourth, the proximal penoscrotal hypospadias associated with diphallia in the present case could result primarily from BMP4 mutation (Table 1) although a contribution from CYP1A1 mutation (Table S1.13) should not be ignored [27].
According to the research by the Huffington Post, Diphallia occurs once in every 5.5 million men in the U.S.
