What is one function of oestrogen in the female body?

One of the primary functions of oestrogen in the female body is to regenerate the endometrium, which is the inner lining of the uterus. This regeneration typically occurs after menstruation and prepares the uterus for a potential pregnancy. Oestrogen plays a crucial role during the menstrual cycle by promoting the growth and thickening of the endometrial tissue, making it suitable for the implantation of a fertilized egg. This process is vital for fertility and overall reproductive health, as a well-developed endometrium enhances the chances of successful conception. The hormonal fluctuations during the menstrual cycle orchestrated by oestrogen are essential for maintaining the reproductive system's normal functioning.
