The first known case of this condition was reported in 1609. Typically only one of the organs is fully formed, but there have been occurrences in which both penises are fully functional! This strange disorder affects an estimated 1 in 5.5 million men.
It’s very uncommon for both penises in diphallus to be fully functional. Usually one of them only has rudimentary functionality. While it might sound awesome, most people would rather not have it. In 2006, for instance, an Indian man in Uttar Pradesh had his second penis surgically removed.
Duplication of the penis is an extremely rare anomaly. Approximately 100 cases have been reported since the first case report by Wecker in 1609. There are broadly three types of diphallus,viz. true diphallus with two independent penises, bifid phallus that may be glandular or complete and pseudodiphallus having a rudimentary phallus in addition to the normal penis. Numerous associated genitourinary and gastrointestinal anomalies have been described with diphallus.

When diphallia is present, it is usually accompanied by other congenital anomalies such as renal, vertebral, hindgut or anorectal duplication. There is also a higher risk of spina bifida. Infants born with PD and its related conditions have a higher death rate from various infections associated with their more complex renal or colorectal systems.
It is thought diphallia occurs in the fetus between the 23rd and 25th days of gestation when an injury, chemical stress, or malfunctioninghomeobox genes hamper proper function of the caudal cell mass of the fetal mesoderm as the urogenital sinus separates from the genital tubercle and rectum to form the penis.
- Those in possession of a diphallus tend to be sterile, due to either congenital defects or difficulties in application.
- Urine may be passed by both penises, by only one, or through some other aperture in the perineum.
- A range of duplication types have been seen, ranging from organs that fissure into two, to the presence of two distinct penises positioned at some distance from each other.
- Most diphalluses lie side by side and are of equal size, but they can be seated atop one another, with one distinctly larger than the other.
- Most men with diphallus learn to use it for intercourse, though they cannot penetrate two partners at the same time.
Diphallia is a medical condition and should not be confused with genital bisection, which is an elective procedure which involves the splitting of the penis. There have been many cases of diphallia males leading excellent sexual lives able to have full penile vaginal intercourse. Some diphallia males have fathered babies with their female partners. Most male babies sired by diphallia males have normal penises.
Supernumerary body parts are most commonly a congenital disorder involving the growth of an additional part of the body and a deviation from the body plan. Body parts may be easily visible or hidden away, such as internal organs.
Many additional body parts form by the same process as conjoined twins: the zygote begins to split but fails to completely separate. This condition may also be a symptom of repeated occurrences of continuous inbreeding in a genetic line.
It has been suggested that deliberately adding supernumerary limbs to humans may be possible, as a form of body modification.
Specific types of occurrence
Specific types of additional body parts include:
- Accessory breast – one or more additional breasts
- Cervical rib – an additional rib
- Diphallia – Having two penes/penises.
- Hermaphroditism – having both sexes’ sex organs
- Hyperdontia – additional teeth
- Pelvic digit – a bony growth in the soft tissue of the pelvic region
- Polycephaly – an extra head
- Polydactyly – additional fingers or toes
- Polymelia — an extra arm or leg.
- Polyorchidism – having three or more testicles
- Supernumerary kidney – a third kidney
- Supernumerary nipples – an additional nipple
- Supernumerary Phantom Limbs – where the brain acts as though a limb is there, but it is not.
- Syndactyly – webbing between the fingers or toes
- Uterine Didelphys – (also Uterine Septum) have two vaginal canals and/or uteri
- Supernumerary bone in the feet – these additional bones are fairly common. They tend to occur between the metatarsal and are frequently mistaken for fractures on x-rays.
