Laser-Assisted Hatching

A specialised IVF laboratory technique that helps embryos hatch from their outer shell, potentially improving implantation in selected patients.
Helpful tools

What is Laser-Assisted Hatching?

Laser-Assisted Hatching (LAH) is an advanced laboratory technique used during In-Vitro Fertilisation (IVF) to help an embryo break through its outer protective layer before implantation.

Each embryo is surrounded by a thin outer shell called the zona pellucida. Before an embryo can implant into the uterus, it must naturally “hatch” from this shell.

In some cases, the zona pellucida may be thicker or harder, making it more difficult for the embryo to hatch.

At Sunfert, we may perform Laser-Assisted Hatching by using a highly precise medical laser to create a tiny opening in the zona pellucida. This can assist the embryo in hatching and improve the chances of implantation in selected patients.

Our embryology team carefully evaluates each embryo to determine whether Laser-Assisted Hatching is necessary before proceeding with the procedure.

Who Can Benefit from Laser-Assisted Hatching?

Laser-Assisted Hatching may benefit certain patients undergoing IVF who have factors that could affect the embryo’s ability to hatch and implant.

At Sunfert, we may consider Laser-Assisted Hatching for patients who have:

  • previous failed IVF cycles
  • advanced maternal age
  • embryos with a thicker zona pellucida
  • limited number of embryos available for transfer
  • frozen embryo transfer cycles

In these situations, Laser-Assisted Hatching may help the embryo hatch from its outer shell more easily, which may improve its ability to attach to the uterine lining.

However, it is important to note that Laser-Assisted Hatching is not necessary for all IVF patients. Our embryology team will recommend it only when there is clinical evidence that it may improve the likelihood of implantation.

How is Laser-Assisted Hatching Performed at Sunfert?

Step 1: Embryo Development

After fertilisation, embryos are cultured in the laboratory for several days while their development is carefully monitored.
 

Step 2: Embryo Assessment

Our embryologists evaluate the embryo quality and the thickness of the zona pellucida.
 

Step 3: Performing Laser-Assisted Hatching

A highly precise laser beam will be used to create a small opening in the outer shell of the embryo.

Laser-Assisted Hatching is performed shortly before the embryo transfer procedure. It can be applied to embryos at the early cleavage stage (typically 2 to 3 days after egg retrieval) or at the blastocyst stage (usually 5 to 6 days after egg retrieval).
 

Step 4: Embryo Transfer

The embryo is then ready for transfer into the uterus.

What is Laser-Assisted Hatching in IVF?

Laser-Assisted Hatching (LAH) is an advanced IVF laboratory technique that helps an embryo break through its outer shell, known as the zona pellucida, before implantation.

A precise medical laser is used to create a small opening, which may support the embryo in successfully attaching to the uterine lining.

Does Laser-Assisted Hatching improve IVF success rates?

Laser-Assisted Hatching may improve implantation rates in specific groups of patients, particularly those with repeated IVF failure or poor embryo hatching potential. However, results vary, and it is not universally beneficial for all patients undergoing IVF.

Does Laser-Assisted Hatching guarantee pregnancy?

No. While Laser-Assisted Hatching may support implantation in selected cases, no IVF technique can guarantee pregnancy. Success depends on multiple factors, including embryo quality, uterine health, and patient age.

Is Laser-Assisted Hatching safe for embryos?

Yes, Laser-Assisted Hatching is considered a safe and well-established assisted reproductive technology.

At Sunfert, it is performed by well-trained embryologists using advanced IVF laboratory technology, ensuring high precision while minimising risk to the embryo.

Is Laser-Assisted Hatching included in IVF treatment costs?

At Sunfert, Laser-Assisted Hatching is included as part of IVF treatment when clinically indicated. Patients are not charged any additional fees for this service.

Is Laser-Assisted Hatching performed before embryo transfer?

Yes. The procedure is done in our IVF laboratory shortly before the embryo transfer to ensure the embryo is ready for implantation.

Is Laser-Assisted Hatching used in frozen embryo transfer (FET)?

Yes, it is commonly considered in frozen embryo transfer cycles, as freezing and thawing may affect the zona pellucida, making hatching more difficult for some embryos.

Is Laser-Assisted Hatching necessary for every IVF cycle?

No. Laser-Assisted Hatching is not required for all IVF patients.

It is only recommended when there is clinical evidence suggesting that the embryo may have difficulty hatching on its own.

The Biological Clock

This tool indicates:

  • Natural conception per month if you have no fertility issues
  • IVF success rate at the same age
  • When to seek help after months of unsuccessful attempts

If you are concerned at any stage – we recommend booking a doctor appointment or a free nurse consultation. The sooner you make a plan the better your chances in the long term.

When to seek advice early

If you have polycystic ovaries, endometriosis, or have been through a cancer diagnosis; we recommend you get in touch quickly so we can talk you through all your options and give you the greatest possible chance of success.

If you’re a single woman considering motherhood in the future; it’s best to approach us early and consider egg freezing as this can be an option for you while you have a higher ovarian reserve and healthier eggs.

Body Mass Index calculator

Being overweight or underweight can reduce fertility, so it is important to keep your body weight within the normal healthy range.

Body Mass Index (BMI) is an indication of your body weight and can be calculated by dividing weight by height. You should aim for a BMI of between 20 and 25, as this will optimise your chances of conception.

Woman’s BMI below 19

Even in these modern times, nature knows best. If a woman's BMI falls below 19, the body senses famine and ovulation is switched off to prevent the risk of having a baby with malnutrition. Excessive exercise can reduce body fat and increase muscle mass to a point where periods cease for the same reason. Risk of miscarriage is also increased in women with a low BMI.

Being underweight

If a woman's BMI falls below 19, the body senses famine and ovulation is switched off to prevent the risk of having a baby with malnutrition. Excessive exercise can reduce body fat and increase muscle mass to a point where periods cease for the same reason. Risk of miscarriage is also increased in women with a low BMI.

BMI’s greater than 30

This can reduce fertility by 50%. Pregnancy for women with a 30+ BMI is often associated with problems such as maternal diabetes, high blood pressure, big babies and increased risk of caesarean section.
