(a) The transitional stage of development from a boy to a young man is called PUBERTY - the period of first becoming capable of reproducing sexually in human physiology.


(b)(i) It is called androgen(男性荷爾蒙), referring to any of a group of hormones that mainly influence the development of the male reproductive system. Androgens cause the normal changes of puberty in boys' bodies and then influence sperm-cell formation, sexual interest and behaviour, and male pattern baldness. The main and most active androgen is testosterone(睾丸素), produced by cells in the testes.


(c) development of sexual feelings
efforts toward the construction of identity
and a progression from concrete to abstract thought
