Topic: Human Growth And Development – Puberty

PUBERTY

Puberty is the transitional biological stage between childhood and adulthood.

It is the stage when the body matures. Puberty involves changes in primary sexual characteristics.

It starts when the pituitary gland at the base of the brain produces hormones. Hormones are chemical substances, which control the body’s development and growth. At puberty, these hormones are secreted to the reproductive organs, that is, the testes and the ovaries in females and males respectively. The reproductive organs thereafter produce sex hormones, which cause changes in the adolescent’s body.

Adolescence begins with puberty. Most girls reach puberty between the ages of 9-13 while boys reach puberty between the age of 12-14. However, children grow at different rates so some may mature later than others.

   HANDLING PUBERTAL CHANGES IN BOYS AND GIRLS

  Pubertal changes could be physical, emotional, social, and internal. These changes must be well-handled

   In Adolescents.

    Adolescents often enter puberty with a heightened sense of sexuality accompanied by a great deal of confusion. At this stage, they are faced with the challenges of forming an identity, false feelings of independence, questions about conformity as well as confusion about values and views of life.

 Hence, pubertal changes must be well handled by applying basic coping strategies or identity. Some strategies for handling pubertal changes are as follows:

  a .Personal hygiene and cleanliness

  b. Self-acceptance.

  c. Emotional Development

  d. Developing decision-making skills which are 

       1 . Identifying and defining a problem

  1. Gather information about the problem
  2. Consider the advantages and the disadvantages
  3. Consider personal and family values about the possible alternatives.
  4. Consider the impact of your decision on other people around you.
  5. Choose one option that will have the best outcome.
  6. Decide and act on the decision cautiously and
  7. Evaluate the outcome of your decision.

   EMOTIONAL DEVELOPMENT EVALUATION

Emotional changes accompany the physical changes of Adolescence. The ups and downs of being a teenager can be difficult for both boys and girls.

Hormones affect a young person’s moods and emotions. An example is feelings of sadness and depression, and shifting feelings about relationships with family and friends.

Adolescents need to be assured that all of these changes are a normal part of growing. As boys and girls enter puberty, their interest in the expression of their sexuality increases. They attain sexual maturity before achieving emotional or social maturity and economic independence. Because of the health risks involved with premarital sex, young people’s decisions and experiences during this transition can affect the rest of their lives.
