The changes that take place are mostly due to the testosterone in males. In girls, the hormone oestrogen is important.
Testosterone, oestrogen, Fsh, LH,prolactinThere are two primary ones: Testosterone, and androgen.

Adrenaline, Insulin, Glucagon, oestrogen, testosterone.

Testosterone, Oestrogen, progesterone.
Puberty is started by the Pituitary Gland (part of the Endocrine system) in the brain sending signals to release testosterone in boys and oestrogen & progesterone in girls. This mass release of the hormones is recognised by the body and begins the process of puberty.Also note that both boys and girls have testosterone and oestrogen, just in different amounts. Boys produce more testosterone and girls produce more oestrogen.
In males, the key hormone(chemical) is testosterone. In females it is oestrogen that drives puberty.
Several hormones exist, and there are many different ones depending on what the body is doing. The main hormones are Testosterone in males, Oestrogen in females and Progesterone in both (however females have a much higher amount).
Prolactin releasing factor
The main androgen is Testosterone with increasing levels that begins Puberty and the Secondary Sexual Characteristics in males. Testosterone is produced in the testes. It encourages growth and maturation. Also important to mention is the Follicle-stimulating hormone (FSH) which enhances spermatogenesis. And, Dihydrotestosterone (DHT) which similarly to testosterone, is a male reproductive hormone that helps the external genitalia to grow and become fertile.
