Bright Future – Sexual Maturity Rating

Sexual maturity ratings (SMRs) are widely used to assess adolescents, physical development during puberty in 5 stages (from preadolescent to adult). Also known as Tanner stages, SMRs are a way of assessing the degree of maturation of secondary sexual characteristics.

sexual Maturity ratings: Males
sMr PubiC HAir
Stage 1 None
Stage 2 Scanty, long, slightly pigmented, primarily at base of penis
Stage 3 Darker, courser, starts to curl, small amount
Stage 4 Course, curly, resembles adult tyoe but covers smaller area
Stage 5 Adult quantity and distribution, spread to medial surface of thighs
sMr GENitAls
Penis testes
Stage 1 Preadolescent Preadolescent
Stage 2 Slight enlargement Slight enlargement of testes and scrotum; scrotal skin reddened, texture altered
Stage 3 Longer Further enlargement of testes and scrotum
Stage 4 Larger in breadth. Glans penis develops. Further enlargement of testes and scrotum
Stage 5 Adult Adult

 

The developmental stages of the adolescent’s sexual characteristics should be rated separately (ie, one stage for pubic hair and one for breasts in females, one stage for pubic hair and one for genitals in males), because these characteristics may differ in their degree of maturity.
