Secondary sex characteristics that typically do not develop during the teen years include:
- Breast development: While some breast development may begin in early adolescence, fully developed breasts typically occur later, often into the late teens or early twenties.
- Body hair growth: The initial phases of body hair growth can start during adolescence, but full development and distribution of body hair (such as chest hair in males or pubic hair) can continue into later adolescence and even into the early twenties.
- Voice deepening in males: While many boys experience voice changes during their teen years, the voice may continue to mature and change even after these years.
- Muscle mass development: Boys typically see an increase in muscle mass during adolescence; however, full muscle development may continue into their late teens and early twenties.
In summary, secondary sex characteristics can begin during the teen years, but their full development can take longer, often extending into young adulthood. If you have specific characteristics in mind, feel free to mention them for a more precise answer.
