Ivf success rate.

Does ivf have a high success rate? At present, the success rate of ivf in China is generally 30-60%. “Test-tube baby” is commonly known as “ivf – embryo transfer”. “Test-tube baby” is not really grew up in a test tube baby, but from her ovaries removed the eggs, combined with the male sperm in vitro embryo formation, and then the process of embryo transfer back into a developing fetus in the uterus. These include superovulation, ovulation, semen treatment, in vitro fertilization, embryo culture and embryo transfer.

From ovarian response to drugs, quality and quantity of eggs and sperm quality, fertilization, to the speed of embryo, embryo quality and endometrial accept ability, hormone fluctuations, a link any exceptions can lead to the failure of the “test-tube baby”.

Factors that affect the success rate of ivf.

The success rate of ivf was mainly affected by age, chromosome, intrauterine environment and infertility, as well as excellent embryo rate and psychological state factors.

1. Physical factors of the operator. Physical factors can be divided into four aspects: age, chromosome, intrauterine environment and infertility.

(1) age.
Age is an important factor affecting IVF success rate, and it is also a normal and vigorous expression of a female reproductive system. With the increase of age, the number of eggs decreased, the quality decreased, the fertilization rate decreased, the pregnancy rate decreased significantly, and the abortion rate increased. The study said that only 20 percent of couples with childbearing age had a pregnancy rate, and that after the age of 35, the body was in decline, especially in the reproductive system. Domestic and foreign literature reported test-tube babies aged 25 to 34 surgery has the highest success rate, success rate of more than 35 years old later there will be significantly lower performance, success rate of more than 40 years of age at about 20%, and live birth rate declined obviously, and the impact on the healthy birth also bigger.
When you are over 45, you can’t use your own eggs for ivf treatment, because the success rate is extremely low, and the chromosomes of the embryo are prone to abnormalities. In IVF treatment, the rate of miscarriage is greatly increased, and premature birth and stillbirth are higher than that of young pregnant women.

(2) chromosomes.
In some primary infertility or couples with a history of adverse pregnancy, if couples there were normal variations in chromosomes, although can be conceived by ivf technology, but the failure rate and abortion rate is higher.

(3) uterine environment.
If endometrial polyps, endometritis, past surgery or inflammation (the most common form of tuberculosis) can cause endometrial injury, it can affect the embryo implantation, thus leading to the failure of the ivf procedure.

(4) infertility symptoms.
Older primary infertility, uterine malformations in patients with severe endometriosis, polycystic ovarian syndrome, from less serious weak sperm and no refined disease patients with testicular sperm, or there are many deformity at egg deformity or development was abnormal, failure rate is also high in ivf treatment.

2. Excellent embryo rate.

When spermatogenesis, egg problem, insemination or fertilization without cleavage cannot complete embryo transfer, excellent embryo is the important condition of success. But good embryos also need a good womb environment, good endocrine conditions, and doctors’ excellent embryo transfer techniques.
Couples in normal childbearing age are only about 20 per cent more likely to conceive when they are in the same room for a month. Therefore, we hope to have a good attitude during the treatment, which is also an important factor of success. Therefore, the excellent embryo rate is closely related to the physical factors of the subject. According to the current medical technology, it can be said that the success rate of the excellent embryo is determined by the physical condition of the couple with artificial insemination.

3. Psychological factors.

Many data indicate that the psychological and mental state of the patient is an important factor influencing the success or failure of IVF treatment. Experts think the psychological pressure heavier women, their endocrine will be affected, blood vessels in a contracting state for a long time, affected the local blood flow to the uterus, ovaries, and of the nervous system causes some neurotransmitter release abnormal, disorder, uterus, fallopian tubes, muscle caused caused embryo does not lead to treatment failure implantation. Therefore, it is very important to relieve the psychological pressure and the communication between doctors and patients. It is very important for couples to understand and encourage each other.
