What are hormones?
Hormones are chemicals that coordinate different functions in your body by carrying messages through your blood to your organs, skin, muscles and other tissues. These signals tell your body what to do and when to do it. Hormones are essential for life and your health.
Scientists have identified over 50 hormones in the human body so far.
Hormones and most of the tissues (mainly glands) that create and release them make up your endocrine system. Hormones control many different bodily processes, including:

- Growth and development.
- Sexual function.
- Sleep-wake cycle.

- Irregular menstruation (periods): Several hormones are involved in the menstrual cycle. Because of this, an imbalance in any one or several of those hormones can cause irregular periods. Specific hormone-related conditions that cause irregular periods include polycystic ovary syndrome (PCOS) and amenorrhea.
- Infertility: Hormonal imbalances are the leading cause of infertility in people assigned female at birth. Hormone-related conditions such as PCOS and anovulation can cause infertility. People assigned male at birth can also experience hormonal imbalances that affect fertility, such as low testosterone levels (hypogonadism).
- Acne: Acne is primarily caused by clogged pores. While many factors contribute to the development of acne, hormone fluctuat
