Effect of hormone level on success rate of test tube infants
IVF technology is an assisted reproductive technology that helps infertile couples realize their reproductive dreams. In this process, hormone level is considered as an important factor, which may affect the success rate of IVF. The following will discuss the influence of hormone level on the success rate of IVF from different perspectives.
Ovarian hormone level
In the process of IVF, women usually receive ovulation induction treatment before receiving assisted reproductive technology to improve the quantity and quality of eggs. This treatment usually includes ovarian stimulators such as FSH (follicle stimulating hormone) and LH (luteinizing hormone). Studies have shown that appropriate levels of ovarian hormones can increase the development and maturation of eggs, thereby improving the success rate of IVF.
First, an appropriate level of FSH can stimulate follicular growth. In the process of ovarian stimulation, the level of FSH is critical to the success of IVF. Appropriate FSH level is helpful to promote the development of multiple follicles, increase the quantity and quality of eggs taken, and thus improve the chances of fertilization and implantation.
Secondly, the level of LH also plays an important role in the formation and maintenance of corpus luteum. In IVF treatment, appropriate levels of luteinizing hormone help maintain luteal function, thus providing a suitable uterine environment to increase the chances of embryo implantation.
Therefore, reasonable control of ovarian hormone level and keeping it within the appropriate range has a significant impact on the success rate of IVF.
Thyroid hormone level
The level of thyroid hormone may also affect the success rate of IVF. Thyroid hormones include TSH (thyroid stimulating hormone), T3 (triiodothyronine) and T4 (tetraiodothyronine), which maintain normal physiological functions by regulating metabolism and energy balance in the body.
A large number of studies have shown that thyroid hormone abnormalities have a certain impact on the success rate of IVF. Hyperthyroidism or hyperthyroidism will lead to ovarian dysfunction, egg quality decline, low implantation rate and other problems, thus reducing the success rate of IVF.
Estrogen and progesterone levels
Estrogen and progesterone are two other important factors that affect the success rate of IVF. Estrogen can improve the quality of embryos and promote the growth of endometrium, while progesterone plays a role in maintaining luteal function in early pregnancy.
Appropriate estrogen level helps to promote embryonic development and adhesion, and also helps to maintain the good condition of endometrium. Appropriate progesterone levels can effectively support the development and implantation of embryos in the uterus. If the levels of estrogen and progesterone are abnormal, the development of embryos and the good condition of endometrium will be affected, thus reducing the success rate of IVF.
summary
There is indeed scientific evidence that the success rate of IVF is affected by hormone levels. Ovarian hormone levels, including the regulation of FSH and LH, the stability of thyroid hormone levels, and the appropriate levels of estrogen and progesterone, all have an important impact on the success rate of IVF. Therefore, in the treatment of IVF, reasonable control of hormone level and keeping it in an appropriate range will help to improve the success rate of IVF.
