Normal Levels of Luteinizing Hormone in Females
The normal level of luteinizing hormone in women is related to fertility and reproduction. It varies widely during the female menstrual cycle, and the numerical differences in each stage are obvious.
In the early stage of menstruation, the level of luteinizing hormone is low, mostly between 2 and 15 mIU/mL. This is the basic state. The body is preparing for the birth of new life, and various physiological functions are running smoothly.
By the time of ovulation, the level of this hormone rises rapidly, reaching 30 to 100 mIU/mL. This surge is a key signal, triggering ovulation in the ovaries, and the egg is released from the follicle, creating an opportunity for fertilization. At this stage, the probability of conception in women increases greatly.
After ovulation, the level of luteinizing hormone gradually decreases, falling back to 10 to 20 mIU/mL, and the luteum produces and secretes progesterone to maintain the stability of the endometrium. If the egg is fertilized, it will create a favorable environment for the implantation and development of the embryo. If it is not fertilized, the luteinizing body shrinks, and the hormone level continues to decline, triggering menstruation.
The normal level of luteinizing hormone in women is of great significance to reproductive physiology. Its value is abnormal, or it may cause ovulation disorders, menstrual disorders, etc., which affect fertility and health. Doctors often use this as evidence to diagnose reproductive system diseases and apply precise treatment strategies to help women maintain a good reproductive state.
