Lifespan perspective refers to the idea that development is a lifelong process. Rapid maturation in which person becomes capable of reproduction. Secondary sex - body hair, changing voice, etc. Menarche (menstruation) and production of sperm occur (spermarche) Puberty is the time of sexual maturation (becoming physically able to reproduce) During puberty, increased sex hormones lead to. Height changes are an early sign of puberty. Because girls begin puberty sooner than boys, girls briefly overtake boys in height. Puberty is being documented as starting earlier and earlier in part because of the hormones that are in the food chain. Puberty timing - the sequence of sexual maturation is predictable, but the time of onset varies from person to person. Maturing early can have social advantages and also increased expectations and risks.
