Which of the following is a female sex hormone?

The correct answer is Estrogen.

Key Points

• Estrogen is a primary female sex hormone responsible for the development and regulation of the female reproductive system and secondary sexual characteristics.
• It is produced mainly in the ovaries, but smaller amounts are also produced by the adrenal glands and fat tissues.
• Estrogen regulates the menstrual cycle, supports pregnancy, and maintains bone density and cardiovascular health in women.
• During puberty, estrogen plays a crucial role in the development of breasts, hips, and other female secondary sexual characteristics.
• Fluctuations in estrogen levels can lead to conditions such as menopause, polycystic ovary syndrome (PCOS), and osteoporosis.

• Gibberellin: A plant hormone that regulates growth and influences various developmental processes, such as seed germination, flowering, and stem elongation.
• Testosterone: The primary male sex hormone, critical for the development of male reproductive tissues and secondary sexual characteristics such as increased muscle and bone mass.
• Progesterone: Another important female hormone that works alongside estrogen to regulate the menstrual cycle and maintain pregnancy.
• Hormonal Imbalance: An abnormal fluctuation in hormone levels, which can lead to various disorders like infertility, osteoporosis, and metabolic issues in both men and women.
