Complete answer:
Puberty is the age period in which both boy and girl become sexually mature. It is the process that usually happens at the ages 10 and 14 for and 12 and 16 for boys. The physical changes that occur at puberty cause different physical changes in boys and girls. There are many changes that occur during puberty.
Two features that are seen in boys at puberty are:
• Growth of facial hairs.
• Voice becomes hoarse.

Two features that are seen in girls at puberty are:
• Development of breasts.
• Thighs become broader.
In girls, only growth of pubic and underarm hairs shows. There is no voice change in girls. Menstruation would be seen in girls at puberty.
In boys, the enlargement of the scrotum and testes and penis also starts growing. The pubic hairs become darker and coarser as it continues to spread.

Body starts producing hormones such as gonadotropin-releasing hormone (GnRH). The pituitary gland also produces hormones such as Luteinizing hormone and follicle stimulating hormone.
