Estrogen, progesterone, and testosterone are essential hormones in female reproductive health. Abnormal levels of these hormones can indicate various conditions, such as polycystic ovary syndrome (PCOS), menopause, or hormonal imbalances. Monitoring estrogen and progesterone levels is vital for assessing menstrual cycle health and fertility, while testosterone levels can help evaluate symptoms like fatigue and hair loss. A thorough understanding of these hormones aids in diagnosing and managing reproductive health issues, ensuring appropriate interventions and treatments.
