Answered step-by-step

The main female reproductive hormone is estradiol, which is a form of estrogen. Estradiol is primarily produced in the ovaries, specifically by the developing follicles and the corpus luteum after ovulation.

Functions of Estradiol at Puberty

During puberty, estradiol serves several essential functions:

1. Development of Secondary Sexual Characteristics:
   • Estradiol is responsible for the development of breasts and mammary glands, which are crucial for future lactation.
   • It contributes to the widening of the hips and the overall body shape changes typical of female maturation.
2. Regulation of the Menstrual Cycle:
   • Estradiol plays a key role in regulating the menstrual cycle by stimulating the growth and thickening of the endometrial lining in preparation for potential pregnancy.
3. Bone Growth and Maturation:
   • The hormone promotes bone growth and contributes to the closure of growth plates, which ultimately determines adult height.
4. Influence on Reproductive Organs:
   • Estradiol helps develop and maintain the health of reproductive organs, including the uterus, fallopian tubes, and vagina, ensuring they function properly during the menstrual cycle.
5. Psychological Effects:
   • Estradiol also influences mood and cognitive functions, contributing to emotional changes often experienced during puberty.
