What is the reason for low LH in IVF?
Low gonadotropin (LH) in IVF is a common problem, which may lead to difficult pregnancy or pregnancy failure. LH is a hormone of pituitary gland, which is very important for the regulation of ovarian function and ovulation cycle. The causes of low LH in IVF and how to solve this problem will be discussed in detail below.
Cause 1: Insufficient endometrium
The health of the endometrium is critical for pregnancy and embryo implantation. If the endometrium is insufficient, it may lead to low LH levels. The causes of endometrial insufficiency may be previous operations, such as myomectomy or intrauterine adhesions, as well as endometrial lesions or infections. In this case, the problem can be solved through endometrial repair surgery or drug treatment.
In addition, lifestyle factors such as low weight, smoking and drinking may also lead to endometrial insufficiency, so improving living habits is also an important measure to solve low LH.
Cause 2: Polycystic ovary syndrome (PCOS)
Polycystic ovary syndrome (PCOS) is a common gynecological disease, which can lead to hormone imbalance and ovulation problems. This disease is characterized by the formation of cystic structures in the ovary, accompanied by polycystic ovaries, high levels of androgen and insulin. Because PCOS patients have abnormal ovarian function, LH levels tend to decrease or increase irregularly. Treatment of PCOS can help promote ovulation by using oral contraceptives, insulin regulators and assisted reproductive technology.
Cause 3: Insufficient pituitary function
The pituitary gland is a gland containing LH secretory cells, LH secretion will decrease. Pituitary dysfunction may be caused by genetic factors, infection, inflammation or tumor. The treatment of pituitary insufficiency can restore normal physiological level by supplementing artificial LH or other hormones.
Cause 4: Other physical factors
Other causes of low LH in IVF may include obesity, malnutrition, stress, autoimmune diseases or the use of certain drugs. These factors may have a negative impact on ovarian function and hormone levels. In order to solve these problems, patients can adjust the LH level by reducing weight, improving diet and lifestyle, reducing stress, etc.
How to solve the problem of low LH in IVF?
Doctors can provide a series of solutions to the problem of low LH in IVF:
Gonadotropin therapy
By using synthetic LH, doctors can help promote ovarian function and ovulation. This treatment usually requires monitoring in the hospital to ensure accurate adjustment of hormone levels.
Assisted reproductive technology
For anovulation caused by low LH, assisted reproductive technologies such as artificial insemination, IVF or intracytoplasmic sperm injection (ICSI) can help pregnancy and embryo implantation.
surgical treatment
Some factors, such as endometrial problems or ovarian cysts, may require surgery. Surgery may include endometrial repair, surgical treatment of polycystic ovary syndrome, or other related operations.
Summary
The causes of low LH in test tube infants mainly include endometrial insufficiency, polycystic ovary syndrome, pituitary insufficiency and other physical factors. For these reasons, we can solve the problem through endometrial repair surgery, drug treatment, improving living habits, gonadotropin treatment, assisted reproductive technology or surgery and other methods. Detailed consultation with doctors and development of treatment plans are the key to solving the problem of low LH in IVF.
