Penile Agenesis and Testicular Agenesis - Physical Appearance

Physical Appearance

Males with penile agenesis but normal testes are of otherwise normal male appearance. Males with testicular agenesis tend not to produce the reproductive hormone 5aDHT at any stage of their lives. As a result, they tend toward prepubescent appearance, with infantile skin texture, developing little body hair particularly in the crotch area, even vellus hair. Without genitalia of either sex, the perineum is therefore left smooth. Also muscular development is retarded and testicular agenetics are of rather frail build with short limbs and small hands and feet. However certain male features are results of other male gender-marker hormones, androgens, which develop male secondary sex characteristics, among which features are the deepening of the voice and facial hair.
