Female fertility issues are a widely discussed topic in society, and among the many factors affecting women’s pregnancy, the level of luteinizing hormone (LH) is an important physiological indicator. LH, as one of the most important hormones in the female body, plays a crucial role in ovulation, pregnancy hormone, and estrogen secretion in women. So, does a low LH level affect pregnancy?

How to determine luteinizing hormone abnormalities?
For women, the levels of luteinizing hormone fluctuate differently in different periods, usually classified into four stages: follicular phase, luteal phase, menopausal phase, and ovulatory phase. During the follicular phase, the normal level is 1.9~12.5 IU/L, during the luteal phase, it is 0.5~16.9 IU/L, during the menopausal phase, 15.9~54 IU/L, and during the ovulatory phase, it is 8.7~76.3 IU/L. Pregnant women have an additional pregnancy stage, with a range of 0~1.5 IU/L! As long as your luteinizing hormone levels are within the corresponding range, it indicates no abnormalities!
First, we need to understand the importance of normal LH levels for female fertility. In a woman’s menstrual cycle, the fluctuation of LH levels is a key factor guiding ovarian ovulation. Typically, a sudden rise in LH levels triggers ovulation, which is one of the prerequisites for pregnancy. Additionally, LH is responsible for maintaining corpus luteum function. The corpus luteum is a temporary gland formed in the ovary after ovulation, which secretes pregnancy hormones and estrogen, providing a suitable environment for the implantation of the fertilized egg and embryo development.
However, when a woman’s LH levels are low, a series of fertility issues may arise. Low LH levels may indicate pituitary insufficiency, leading to a further decrease in sex hormone levels and affecting ovulatory function. Once ovulation is hindered, the possibility of pregnancy naturally decreases significantly. What’s more serious is that even if a woman is fortunate enough to conceive, due to inadequate corpus luteum function, the implantation and development of the embryo may be affected, increasing the risk of miscarriage.

There can be various reasons for low LH levels, including pituitary adenoma, hypothalamic dysfunction, ovarian insufficiency, excessive dieting, drastic weight changes, etc. Additionally, factors like high life stress, emotional fluctuations, environmental pollution, unhealthy lifestyle habits, etc., may also indirectly affect LH levels.
For women in the preconception period, if irregular menstruation or ovulatory disorders occur, it is advisable to promptly seek medical attention and check LH levels. Through hormone testing, doctors can assess a woman’s fertility and provide appropriate treatment recommendations. Treatment measures may include hormone replacement therapy, drug therapy, surgical treatment, etc., aimed at regulating LH levels and restoring normal ovulatory function.
In conclusion, low luteinizing hormone levels are a fertility issue that should not be ignored. As women, we should prioritize our physiological health, undergo regular check-ups, identify and address potential risks that may lead to fertility disorders. Additionally, society and families should provide women with more care and support, collectively creating a conducive environment for women’s health and fertility.
