Knowing Success and Live Birth Rate of IVF

In today’s world, IVF treatment is very common among the people. IVF refers to In Vitro Fertilization. It is an easy procedure in which the eggs are retrieved from the female ovaries and then are combined in a vitro, with the sperm of a husband or sperm from donor. When the embryo is formed from that fertilization, then it is transferred back in to the female uterus for the natural process to begin. IVF treatment is used by a couple, if they fail to conceive the pregnancy even after having regular sexual intercourse for a year or more and if no medication has helped them to conceive.

 Success rate of IVF is referred to basically the rates of pregnancy after the procedure of IVF. The age of the woman play a vital role for the success of IVF treatment. As the age of the woman increase, the success rate of IVF keep on decreasing especially after the age of 37. Another factor that helps in evaluating the success rate is the number of embryo transferred. The success rate of IVF also depends on how many embryos are being transferred to the female uterus. However, transferring more than one embryo arise the risk for multiple pregnancies and birth defects, miscarriages, pre mature births, etc. According to the doctor, not more than two embryos should be transferred to the uterus in the women under 35 ages, as there is a risk of multiple pregnancies.

In the process of IVF, there is a risk of low birth weight or premature birth, due to the higher risk of multiple pregnancies. According to the research, approximately 30 percent of IVF treatment results in twin, when compare to natural pregnancies. The success rate of IVF generally depend o the IVF procedures that provide the beneficial outcome. The confirmed pregnancies represented by the calculation for the specific outcome are responsible for the pregnancies success rate in IVF and the number of live birth rate in IVF. Usually, the success rate is affected by various factor like; infertility cause, age of the woman, status of embryo, function of reproductive system and lifestyle and environmental aspects.

Mostly the women under 35 years of age are more likely to get pregnant with the IVF treatment even with one embryo placed in their uterus. However, the women aged over 40 years get difficulty in getting pregnant with one embryo implanted in them. For the success of pregnancy, they need to get implanted more than two embryos in their uterus and might also get the use of a donor egg. On the other hand, the women who have conceived a pregnancy before or have given birth to a child previously are more likely to conceive pregnancy through IVF treatment as compared to the woman who have never been pregnant before.

According to the reports, the IVF success rates have reached higher today as compared to the previous couple of year ago, due to the development in the advanced reproductive technologies.

There are several factors that affect the success rate of IVF treatment. Some of them are mentioned below-

·         Experience of the IVF specialist

·         Quality of egg

·         Maturity of the egg

·         Age of the woman

·         Quality of sperm and morphology

·         Abnormalities of chromosomal in the eggs and the sperm

·         Reproductive abnormalities including, endometriosis and uterine fibroids 

Understanding the live birth rate in IVF-

The live birth rate in IVF is calculated by the number of healthy babies born through the IVF procedure which is undergone when there is an infertility diagnosed in a couple. The women aged less than 35 year have 24 percent of chance for live birth per cycle, whereas the women of aged 35 to 39 year have 18 percent chance for live birth cycle and women of 40 year and above have only 7 percent chance of a live birth per cycle. If we compare the success rate of pregnancy through IVF with live birth rate in IVF, then we can find that the live birth rates are lower than the success rate of pregnancy through IVF.

A woman who has a well functioned reproductive system and is able to produce eight fine eggs in her one cycle, can obtain a pregnancy rate of 37percent each embryo implanting, and a live birth of 25percent at her first attempt in IVF procedure. The numbers of eggs obtain from ovaries after the ovarian stimulation also has a great impact in the success of IVF treatment.
