Every hormone is produced by male and female as testestrone are produced in female and progesterone and estrogen in male the Have supportive role.

LH is used in males for production of testosterone

I think there is no such hormone which is produced but not used

Hormone Secreted in Both Males and Females but Only Functional in Females: Estrogen

Estrogen is a hormone that is secreted in both males and females, but it has a more prominent role and functions specifically in females. It plays a crucial role in the development and regulation of the female reproductive system, including the menstrual cycle, pregnancy, and secondary sexual characteristics.

Functions of Estrogen:

1. Development of Secondary Sexual Characteristics: Estrogen contributes to the development of secondary sexual characteristics in females, such as breast development, widening of hips, and distribution of body fat.

2. Regulation of the Menstrual Cycle: Estrogen is responsible for the growth and development of the endometrium (lining of the uterus) during the menstrual cycle. It stimulates the proliferation of the endometrial cells, preparing the uterus for possible implantation of a fertilized egg.

3. Promotion of Ovulation: Estrogen levels rise during the menstrual cycle and peak just before ovulation. It promotes the release of luteinizing hormone (LH), which triggers the release of a mature egg from the ovary.

4. Maintenance of Pregnancy: During pregnancy, the placenta produces a significant amount of estrogen to support the growth and development of the fetus. Estrogen helps maintain the pregnancy by promoting blood flow to the uterus and supporting the growth of the uterine lining.

5. Regulation of Bone Density: Estrogen plays a crucial role in maintaining bone density in females. It helps inhibit the breakdown of bone tissue and promotes the formation of new bone.

6. Impact on Cardiovascular Health: Estrogen has a protective effect on the cardiovascular system. It helps maintain healthy cholesterol levels, promotes vasodilation, and reduces the risk of heart disease in premenopausal women.

Importance of Estrogen in Females:

Estrogen is essential for the overall health and well-being of females. It is involved in the regulation of the menstrual cycle, fertility, pregnancy, and the development of secondary sexual characteristics. Estrogen also plays a significant role in maintaining bone health and cardiovascular health in females.

While estrogen is present in both males and females, its levels and functions are more prominent and specific to females. Understanding the role and functions of estrogen is crucial in addressing various female health concerns and optimizing overall reproductive and general health.
