What is the primary role of Lutenizing hormone in females?

Luteinizing hormone (LH) plays a crucial role in the female reproductive system, primarily in the regulation of the menstrual cycle and ovulation. One of its key functions is to stimulate the formation of the corpus luteum following ovulation. After an egg is released from the ovary during ovulation, LH ensures that the remaining follicular cells transform into the corpus luteum. This structure then produces progesterone, which is essential for maintaining the uterine lining for potential implantation of a fertilized egg.

The importance of this function lies in the fact that the corpus luteum and the progesterone it secretes are critical for establishing and maintaining a pregnancy. Thus, the primary role of luteinizing hormone in females centers around its influence on the corpus luteum's formation and functionality after ovulation has occurred. This is fundamental for fertility and reproductive health.
