The first laser-assisted zona drilling was reported in 1991. It could thin the pellucida without making a hole. Today it is a prominent success factor of IVF. Patients often are hesitant since they fear embryo damage by artificial cracking. But the chances are extremely low. Instead, it makes it easy for ‘advanced eggs’ to break through the outer shell. This increases the chances of expansion and attachment to the uterus wall. Hatching is an indispensable step of IVF since pregnancy is impossible otherwise. The top fertility centre in Delhi ensures that the process is fast, safe, effective and affordable.
Consider learning about laser-assisted hatching if you have opted for infertility treatments. It will help you understand what is being done to the eggs. You are assured a well-informed experience that helps for the next IVF, if any. Have a look.
LAH Procedure
The method is performed accurately by a highly qualified embryologist. A strong light beam is sent to weaken the shell. The perforation usually takes place via vaporization. This makes it easy for the embryo to come out. It is then placed back into the culture medium awaiting transfer into the womb. Studies found that natural hatching in human blastocysts takes place near the inner cell mass. The laser method tries to imitate this behaviour to boost the implantation chances of IVF patients at a fertility hospital.
Technicians can use advanced software to position and focus the laser. The heat intensity is adjusted according to the thickness of the zona. Speed and precision are other factors that can be worked up according to the structure of the outer embryonic shell. The method is usually performed three days post-fertilization. This is when the embryo begins to divide.
Signs you Need an LAH
Not every patient requires assisted hatching. But certain obvious indications show that it is necessary to enhance the chances of successful fertilization.
- Excessive fragmentation of the embryos.
- Slow developing or low-quality embryo.
- The eggshell is abnormally thick and hard.
- Cryopreserved embryos are being used.
These conditions can impair the success rates of IVF. So, doctors at leading fertility centres in Delhi do not take a chance. The best location for the hatching is determined. A beam is thrown on the zona pellucida from a distance. This protects it from external damage. Few more laser pulses can also be fired depending on the shell requirement.
Ideal Candidates for LAH
Everyone can surely benefit from laser hatching. But it is specifically recommended for anyone above the age of 37 with unsuccessful IVFs. You are also eligible in case the body is producing high follicle levels. Stimulating hormones early in the infertility treatment can also benefit from the assisted procedure. Good control over drilling with minimum side effects make it a viable option for everyone in general.
LAH does not cause any congenital diseases in babies. It can only improve the chances of positive pregnancy and healthy motherhood. Collaborate with a highly reputed fertility clinic to increase the odds of success.
