In males, which Tanner stage is associated with almost full pubic hair?

In males, Tanner Stage 5 is associated with nearly complete development of pubic hair, which typically resembles the adult pattern. By this stage, pubic hair extends to the inner thighs and has a full texture. Tanner stages outline the physical development during puberty, and Stage 5 represents the final stage of maturation.

In contrast, Tanner Stage 2 features sparse pubic hair, mostly limited to a few straight, fine hairs. Stage 3 indicates the beginning of more dense hair growth, but it is still not fully developed. Tanner Stage 4 shows significant hair growth but not to the extent seen in adults—hair may be coarser and darker but does not yet cover the area fully and may not extend to the inner thighs. Thus, the characteristics of Tanner Stage 5 are what define it as the stage with almost full pubic hair, distinguishing it from earlier stages in terms of physical development.
