Anatomy
Conical distal end of penis, with slit opening (meatus or external urethral orifice), sensitive homologue of clitoris, ordinarily covered partially/fully in flaccid state by retractable foreskin/prepuce (removed in circumcision), is the expanded end of corpus spongiosum molded around joined ends of corpora cavernosa, its base bulging as a corona distal to a sulcus at neck of penis (to which foreskin fold is attached).
Physiology
Many free nerve endings, involved in sensation of pleasure in sexual arousal, excitation, orgasm.
Clinical
Balanitis, inflammation of glans, affects around 1 in 15 (1 in 3 with diabetes), can be non-/infective, may be associated with poor hygiene, commoner in uncircumcised.
