Well, you need evry single one of them but the most important one id yhe endocrine system.
The Endocrine System houses the Pituitary Glandwhich releases hormones that cause the onset of puberty.
The reproductive system matures during puberty.
Its different for boys and girls. For boys, don't pressure girls into sex. Girls don't give in to sex. And both should be more mature.
These parts are different in females and males. In males, testies grow while in females breasts grow.

There are many physical changes like the increase in height and weight. But more importantly the reproductive system becomes fertile.
changes in the reproductive system
during puberty
Hormones released by the endocrine system cause the changes associated with puberty.
Puberty is apparently triggered by a chemical from the hypothalamus gland, which stimulates the release of hormones by the pituitary gland, which in turn causes sex hormones to be generated in the ovaries (female) or testes (male). Puberty normally occurs between the ages of 10 to 17 for girls, and 12 to 18 for boys. Puberty is the post-adolescent onset of sexual physiology, as the body completes the development of the reproductive system. This includes hormonal changes, as well as associated behavioral attitudes and inclinations. Boys become more interested in girls, and girls in boys. This is the beginning of human adulthood. Changes in the body are not limited to sexual ones, but encompass extensive physical and mental alterations that define gender differences.
Thymus
During puberty, our reproductive system becomes fertile. Also the sex hormones cause the romantic feelings as we have to procreate .
The Thymus Gland. It grows slowly until puberty then fully develops thereafter.
The hormone is called estrogen. Some of the changes that it causes are as follows: •Shedding of the uteral lining. (period) •Increased sexual experiences/thoughts. •Greater development in key areas to the reproductive system.
The nervous system is responsible for doing this.
