What is hatching IVF?

Failure of IVF process or IVF fertilization can be frustrating, which is usually due to a failure of the embryo to implant. For women who have had at least one failed IVF course, a fertility specialist may recommend a hatching procedure to help conceive implantation. In this post you will be introduced to the technique of hatching and improved implantation in IVF method.

How is the Hatching procedure?

In IVF treatment, after fertilization of the egg in the laboratory, cell division begins. In the early stages of development, embryos are surrounded by a protein coating called zonaplusidae. In order to continue implantation in the uterine wall, embryos must be excluded from the zona pellucid protein coating.

In normal fertility, this layer is made thinner by the enzymes secreted by the embryo and the uterus and allows the embryo to adhere to the uterine wall. In the IVF method, some factors such as maternal age and high levels of vacuum in the mother's blood may prevent the skin from thinning and reduce the chance of implantation.

Scientists' research on IVF has shown that embryos with thinner zonaploid skin have been more successful in implantation. For this reason, experts have developed a new technique for artificial thinning of this layer to improve the chance of implantation in IVF. Hatching is a laboratory method in which a neurologist under a microscope using a laser or chemicals thin the skin of the embryo's zona pellucid to aid implantation in the uterus after transplantation. Hatching is usually performed on the fourth day of embryo development, which is divided into six to eight cells on average. The hatching process is performed in the laboratory before the embryo is transferred and does not require the presence of the mother.

Hatching prescriptions and success rate

The hatching technique can help couples whose embryos may not have enough energy to tear the shell and implant. Hatching techniques are usually recommended to women in the following situations:

Ages over 37 years old
Two failed periods of IVF or more
In cases of frozen embryo transfer
Low embryo quality and slow growth and inadequate

This technique increases the chances of success in people who have had two failed IVF rounds. The results of one study showed that with all the women in the study, hatching increased the percentage of embryos adhering to the uterine wall, especially in women over the age of 37 or women with higher than normal levels.

Because hatching or laser hatching is a modern and difficult technique, its success depends on the expertise and skill of the psychologist. For this reason, it is advisable to ask your doctor if your doctor recommends hatching for the clinic's success and ability.

When is assisted hatching done in IVF?

Assisted hatching is generally performed on the third day of embryo development. The embryologists use a laser to create a very small hole in the zona pellucida. Assisted hatching can also be done on previously frozen and thawed embryos.

Does assisted hatching increase chances pregnancy?

Assisted hatching is a procedure where we can help the embryo “hatch” from its “shell” by creating a small crack in the zona pellucida. It is believed that assisted hatching can help an embryo implant in the uterus, leading to higher pregnancy rates in some patients. Assisted hatching is a newer lab technique that was developed when fertility experts observed that embryos with a thin zona pellucida had a higher rate of implantation during IVF. With assisted hatching, an embryologist uses micromanipulation under a microscope to create a small hole in the zona pellucida.

Is assisted hatching necessary?

Assisted hatching is not recommended for all patients, but may be helpful in women who are older (more than 37 years old) or who have had a prior IVF failure. A Cochrane review on assisted hatching—that considered 31 studies, totaling 1,992 pregnancies, and 5,728 women—found that assisted hatching just slightly improved clinical pregnancy rates.

Can assisted hatching cause twins?

The risk for identical twins might be slightly increased when assisted hatching is applied. Medical complications are higher in identical twin pregnancies than in normal, singleton pregnancies.

How long does it take for a hatching blastocyst to implant?

In the case of in vitro fertilization (IVF), the fertilized eggs or human blastocysts normally hatch out of their shell and start to implant about 1 or 2 days after the 5th day of the IVF blastocyst transfer. This means the implantation takes place about 7 to 8 days after fertilization of the egg. The time required for implantation in both the cases, normal pregnancy and pregnancy through IVF, is more or less the same.

10 common question about Assisted hatching ivf

1Does assisted hatching improve implantation rates?

Assisted hatching is thought to possibly help with the embryo implantation and is more likely to be recommended when there has been repeated unexplained IVF failure or for patients with a poor prognosis. ... This is because assisted hatching hasn't been shown to improve live birth rates.

2How long does it take for an embryo to implant with assisted hatching?

When the embryo reaches the blastocyst stage (100-200 cells) approximately 5 days after retrieval, it is transferred to the woman's uterus. Here, the shell must be able to hatch the embryo so that it may adhere to the uterine wall, implant itself into the uterine lining and continue to grow.

3How much is assisted hatching?

The fee for assisted hatching is generally between $400 to $1,000. At most clinics, this cost is in addition to the regular costs of a cycle of IVF. At some clinics, assisted hatching is included in the price for IVF, because some clinics believe that assisted hatching improves the pregnancy rates for all embryos.

4Can a 5 day blastocyst split into twins?

There is an increased risk of identical twins with blastocyst transfers. ... Any couple wishing to avoid the chance of twins for any reason may choose single blastocyst transfer. In natural conception, fertilized eggs do not enter the uterus until five days after fertilization.

5Can assisted hatching damage the embryo?

Rarely, assisted hatching can damage the embryo, making it unusable. The risk for identical twins might be slightly increased when assisted hatching is applied.

6Does assisted hatching increase chances pregnancy?

Assisted hatching involves the artificial breaching of the zona pellucida, or the embryo's outer shell, as a technique to improve implantation and pregnancy rates following IVF. ... This procedure may occasionally increase the chance that an embryo will implant in the uterine wall and facilitate a successful pregnancy.

7Do assisted hatching embryos implant sooner?

In addition, hatched embryos implant one day early, which may allow a greater opportunity for implantation to occur, particularly if the endometrium is advanced by the ovarian stimulation in a fresh transfer. The addition of assisted hatching to the standard IVF protocol does add extra laboratory manipulation.

8What does assisted hatching mean in IVF?

Assisted hatching is a fertility technique, used as part of IVF treatments, to facilitate the embryo hatching and implantation process. A fertilized embryo is covered by a shell, called the zona pellucida. ... Once the zona is sufficiently thinned, it tears allowing the embryo to hatch.

9Do hatching embryos implant sooner?

Human blastocysts should hatch from the shell and begin to implant 1-2 days after day 5 IVF blastocyst transfer. In a natural situation (not IVF), the blastocyst should hatch and implant at the same time - about 6 to 10 days after ovulation.

10Are hatching blastocysts good?

Since blastocysts are "very good embryos" they tend to freeze and thaw very well. On the other hand, good day 3 embryos also freeze and thaw well. However, for the last 5-6+ years, ACFS has cultured all their patients' embryos to the blastocyst stage with excellent results.
