What are Hormones in a Girl?
Girls produce several key hormones that regulate various bodily functions and contribute to their development and reproductive health. The primary hormones are estrogen, progesterone, and testosterone, though in smaller quantities than in males.
-
Estrogen: This is the primary female sex hormone. It's crucial for the development of female secondary sexual characteristics during puberty, such as breast development, widening of the hips, and the regulation of the menstrual cycle. Estrogen also impacts the reproductive tract, urinary tract, heart, blood vessels, bones, and breasts. [Source: Johns Hopkins Medicine]

Progesterone: This hormone works closely with estrogen. It primarily plays a role in preparing the uterus for pregnancy and maintaining a pregnancy once it's established. [Source: Medical News Today, Healthline]
-
Testosterone: Although considered a male hormone, girls also produce testosterone in smaller amounts. It contributes to libido (sexual desire), bone density, and muscle mass. [Source: Medical News Today, WebMD]

The ovaries and adrenal glands are the primary sites of sex hormone production in females. [Source: Medical News Today (as referenced in the prompt)]
Hormonal Changes Throughout Life:
Hormone levels fluctuate throughout a girl's life, with significant changes occurring during puberty and the menstrual cycle. These fluctuations influence physical development, reproductive capabilities, and overall health. [Source: Merck Manual - Puberty in Girls, Merck Manual - Menstrual Cycle, Moreland OBGYN]
