Earliest detectable secondary sexual characteristic is breast bud development in girls, testicular enlargement in boys.

pg32  How did you know this? The Tanner stages in FA simply list pubarche and breast buds developing in the same stage without stating which comes first. Thanks! +  
lynn  @pg32 look at the paragraph above the diagram, it says that exactly. Took me a minute too lol +1

Found these notes written into my FA, unknown where they came from but has gotten me questions correct thus far.

Males: Testicular growth -> Penile Growth -> Pubarche -> Growth Spurt -> Spermatogenesis

Females: Thelarche -> Pubarche -> growth spurt -> Menarche

Take a look at FA pg.623 for tanner stages of sexual development.
