In our reproductive center, the stories of some pregnant sisters often encountered are heart-wrenching: they have experienced many non-implantation or biochemical fetal arrest, and even after using anticoagulant drugs such as heparin and aspirin according to doctor's advice, they still failed to preserve the precious fetus.

When these sisters almost ran out of hope, a seemingly common check-up indicator-blood lipids often revealed the root cause of the problem. The good news is that once this problem was addressed, many sisters finally succeeded in welcoming their babies.
Before treatment for IVF, doctors usually require a series of tests, including blood lipids.
,,.Blood lipids are the content of fat in the blood, mainly including cholesterol and triglycerides.
?Studies have shown that pre-pregnancy high cholesterol, high triglyceride and low-density lipoprotein can affect the success rate of IVF. These abnormalities can reduce the sensitivity of the ovary to ovulation-inducing drugs, affect egg quality and fertilization rates, thereby reducing the success rate of pregnancy.
Abnormal blood lipid levels can have two main effects on pregnancy: first, they can affect ovarian function and embryo implantation; second, they increase the risk of complications during pregnancy.
2020<>,30%.Among these women, the proportion of successful pregnancies was significantly lower than that of women with normal blood lipids.
Second, why does high blood lipid levels hinder embryo implantation?
,,,.This means that the "nutrient channel" between the uterus and the embryo-the tiny blood vessels that connect the two-may be blocked.
When blood vessels are blocked by tiny clots, the supply of blood to the embryo becomes severely insufficient. This is equivalent to cutting off its supply of food and oxygen, making it difficult for the embryo to implant properly. Even if it manages to implant, it may still stop developing due to inadequate nutrition, leading to a termination of pregnancy.
What’s more serious is that poor blood circulation can also lead to excessive blood flow in certain areas or a sudden increase in pressure. This can cause already fragile tiny blood vessels to rupture and bleed, resulting in the accumulation of fluid in the uterine cavity. All of these factors can hinder the process of achieving a successful pregnancy.
Third, why is heparin/aspirin sometimes ineffective?
,,.However, some sisters clearly used medicine, but still couldn't escape the end of a bed or fetal arrest. The key problem may lie in the root cause of "high blood lipids"!
Heparin and aspirin target different stages of the coagulation process. Heparin primarily reduces the activity of clotting enzymes and decreases the “activity” of clotting factors. Aspirin, on the other hand, inhibits platelet aggregation, preventing platelets from clustering together and forming clots.

High cholesterol and blood lipids were detected during pregnancy preparation. How to improve it?
,,?Do I have to take lipid-lowering drugs? The answer is clear: statins are not recommended most of the time, and blind medication may affect "good pregnancy".
,“”--.If cholesterol synthesis is inhibited, sex hormone raw materials will be insufficient, which will affect follicular differentiation and hormone balance.
Dietary adjustments: Choose light and easily digestible foods and increase your intake of fiber and vitamin C.
:,C.Eat more coarse grains, such as millet, oats, beans and other lipid-lowering foods, and avoid high-fat and high-salt foods.
Moderate exercise: Engage in aerobic activities at least three times a week, such as walking, running, or swimming. Each session should last 30-50 minutes. This can help improve blood circulation and lower blood lipid levels.
Weight management: Maintaining an appropriate weight helps to improve blood lipid levels and reduce the risk of complications during pregnancy.
Regular monitoring: During the treatment process, it is necessary to regularly check blood lipid levels, assess the effectiveness of the treatment, and adjust the treatment plan accordingly.
Ms. Li's experience is a good example.
.Before undergoing IVF, she discovered that her total cholesterol level was as high as 6.5 mmol/L (normal values should be lower than 5.2 mmol/L). After three months of diet control and exercise, her blood lipid levels were successfully reduced to the normal range, and she finally became pregnant smoothly.
Experts emphasize that it typically takes 3 to 6 months to adjust blood lipid levels. Couples planning to undergo in vitro fertilization should plan accordingly and allocate sufficient time for the adjustment process.
Based on clinical data, through scientific treatment, this number has brought hope to many families planning to have children.
