Rather than a single organ, the deceased individual possessed three structures corresponding to penises, a condition identified in medical literature as triphallia.
Discovery at the Birmingham Medical School Anatomy Lab
The unusual finding remained entirely hidden during the man’s life. External genitalia appeared completely normal upon visual inspection, with one primary organ situated in the standard anatomical position. However, two additional structures were concealed entirely beneath the skin of the scrotum. Researchers noted that the routine dissection process provided the necessary internal access to identify the anomaly, marking only the second documented case of human triphallia in medical records.
Anatomical Structure of Triphallia
Detailed examination by the university researchers revealed that the extra formations were not merely superficial skin tags or random tissue growths. All three structures contained cavernous bodies and featured distinct glans-like endings. The largest structure remained the primary visible organ, while the two smaller counterparts were stacked vertically beneath the scrotal skin. Two of the three formations maintained connections to the urinary tract, whereas the smallest internal structure lacked any corresponding urethral passage.
Developmental disruptions cause rare tripleorgan formation during embryonic growth
Poliphallia stems from developmental disruptions during early embryonic growth when genitalia structures first form. While exact biological triggers remain difficult to isolate, medical literature records cases of diphallia with relative frequency compared to the extreme rarity of triphallia. Prior to this discovery, researchers had documented only one other human instance of a triple-organ formation. Documenting these structural variations helps medical specialists better understand complex embryonic development pathways and rare congenital malformations.
Students uncover hidden structures during standard anatomical dissection
How did the medical students discover the hidden organs?
Students uncovered the two additional structures beneath the scrotal skin while performing a standard anatomical dissection of the donated body in the Birmingham lab.
Did the extra organs function during the man’s lifetime?
External genitalia appeared entirely normal from the outside, and because two of the extra structures were concealed beneath the skin and lacked complete urinary connections, the anomaly went undetected throughout the man’s life.
What is the difference between diphallia and triphallia?
Diphallia refers to the presence of two penises, which appears more frequently in medical literature, whereas triphallia involves three distinct genital structures and represents an exceedingly rare form of poliphallia.
