Identify the female hormone that also plays a role in the maturation of eggs.

Estrogen is the hormone that primarily plays a significant role in the maturation of eggs in females. This hormone is produced mainly by the ovaries and is crucial for the development and regulation of the female reproductive system and secondary sexual characteristics. During the menstrual cycle, estrogen levels rise, leading to the maturation of ovarian follicles, which contain the developing eggs. It is also involved in preparing the uterine lining for potential implantation of a fertilized egg. While the other hormones listed have important functions, such as prolactin in milk production and testosterone in male characteristics, they do not have the same direct role in egg maturation as estrogen does.
