In vitro fertilization (IVF) or IVF is indeed a solution for couples who have difficulty having children. Does this one procedure always work? Come on, find out the success and failure rate of IVF through this article
Infertility or infertility is defined as the condition of not getting pregnant or having difficulty conceiving after 1 year or more of being pregnant. Difficulty getting pregnant can be caused by a man's or woman's he alth conditions.
In women, for example, difficulty getting pregnant can be caused by ovulation disorders, endometriosis, or PCOS. Whereas in men, difficulty in getting offspring can be caused by low sperm count or quality, infection, hormonal disorders, or autoimmune diseases.
Well, to overcome infertility due to the causes mentioned above, IVF or IVF procedures can be one of the methods of choice to get offspring.
This is IVF Success Rate
In vitro fertilization is a procedure in which egg and sperm cells are combined in a laboratory. If fertilization is successful, the prospective embryo will be implanted into the woman's uterus so that it can develop.
In general, IVF programs are intended for couples who do not have children, even though they have routinely had sex at least 2-3 times a week without using any contraception, including condoms.
However, IVF is also often recommended for couples who are over 35 years old and have fertility problems.
The success rate of IVF can vary. This depends on the quality of the prospective embryo produced by the fertilization of the egg and sperm cells. In addition, the age of the woman also affects this success rate. If described further, here is the explanation:
- For a 35 year old woman, the success rate is around 54.5%
- For women aged 35–37 years, the success rate is around 41.1%
- For women aged 38–40 years, the success rate is around 26.7%
- For women aged 41–42 years, the success rate is around 13.8%
- For women over 43 years of age, the success rate is around 4.2%
The older the woman who will be the place for the embryo to develop, the success rate of IVF will also decrease.Several other factors that affect the success rate of IVF are the lifestyle you live, your weight, the type of egg used (frozen or fresh), to the quality of your partner's sperm.
In addition to those mentioned above, data from the Indonesian In Vitro Fertilization Association in 2017 stated that the success rate of IVF programs in Indonesia reached 29% or equivalent to international data, where the average success rate was 25–30%..
Opportunities of Failure and Some of the Causes
Although the IVF success rate is quite high, this procedure still has a non-small chance of failure. One of the phases in the IVF process that often causes pregnancy failure is the implantation phase or the implantation of the fertilized embryo.
Failure of this phase, especially if it has happened repeatedly more than 3 times, can be caused by many things, including:
1. Woman's age
As mentioned earlier, a woman's age greatly affects the success rate of IVF. As women get older, the success rate of this program will decrease.
A woman's age has an effect on the success of the transfer of the embryo to the uterus. Based on research, the success rate of frozen or fresh embryo transfer in women under 35 years old can be 41.3%–47.1%. Meanwhile, for women over 44 years of age, the success rate is only 1.9%–16.2%.
2. Body mass index
In vitro fertilization (IVF) for overweight or obese women has a high rate of embryo implantation failure. In addition, obese women are also said to be more at risk of miscarriage.
3. High stress level
Research has found that high levels of cortisol or the stress hormone in women can increase the risk of miscarriage, especially in the first trimester. This is also believed to affect the failure of the IVF program.
4. Smoking habit
If you and your partner want to undergo IVF program, you should stop smoking and avoid inhaling cigarette smoke. The reason is, the substances in cigarette smoke can cause poisoning to the fetus, block the flow of oxygen to the fetus, and increase the risk of miscarriage.
Cigarettes can also reduce sperm quality, damage the structure of sperm, inhibit the fertilization process in the egg, and reduce the ability of sperm to swim properly. These all greatly affect the success and failure of the IVF program.
In vitro fertilization or IVF can indeed be a solution for couples who have difficulty having children. However, keep in mind that this method is not always successful and is influenced by many factors.
So, if you and your partner have difficulty conceiving and are considering trying IVF, consult your doctor to find out if this is the most appropriate way to solve your problem.
If you and your partner are recommended to undergo IVF and this method is successful, don't forget to also prepare some important equipment to welcome your little one, such as clothes, diapers, and toiletries, to telon oil.
