We all have eaten sprouts at some point in our lives. Have you come across that one nasty grain or a pulse that is so hard to chew that it hurts our teeth? That grain must have not sprouted if you observe. Although your mom kept all the conditions same for all the grains, some stubborn grains don’t seem to sprout or hatch.

Similarly, some stubborn embryos in an IVF lab don’t easily hatch even if all conditions required are fed to it.

Just like how a seed must sprout for it to implant itself onto the soil to grow into a plant, an embryo must hatch out of it Zona Pellucida to implant itself onto the endometrium for it to grow into a baby

Here the seed is the embryo and the soil for it is the endometrium 

So, what do we do with the embryos that are like the nasty hard grains that won’t sprout?

We break their wall or the Zona Pellucida in this case!
