Hormone Changes During Puberty
During puberty, there are several hormone changes that occur in the body. These hormone changes are responsible for the physical and emotional changes that happen during this time. Here are some of the main hormones related to puberty and the changes cause:
- Testosterone: This is a primary sex hormone in males. It gives rise to male traits, such as a deeper voice, facial hair, and muscle development. Testosterone also plays a role in female development, although to a lesser extent than in males.
- Dihydrotestosterone (DHT): This hormone is more powerful than testosterone and is present in higher amounts during puberty. It starts puberty in males and may also help start puberty in females.
- Estrogen: This is a primary sex hormone in females. It promotes the growth of uterus (womb) and breast tissue.
- Estradiol: This hormone is a type of estrogen that is present in both males and females. In females, the levels of estradiol rise earlier and remain higher after puberty.
- Growth hormone: The levels of growth hormone increase during puberty, causing growth spurts in the bones and muscles, along with a rapid increase in height. If there is a slower height increase of less than 2 inches per year, it may signal a hormone deficiency.
These hormone changes during puberty are responsible for the development of secondary sexual characteristics, such as breast development, the appearance of pubic hair, and changes in body size and shape. They also play a role in emotional changes that occur during this time.
It's important to note that everyone's experience with puberty is unique, and these changes can vary from person to person. If you have any concerns or questions about the hormone changes during puberty, it's always a good idea to talk to your doctor or healthcare provider for personalized advice and guidance.
