Intracytoplasmic Sperm Injection commonly referred as ICSI, as the name suggests is a method of injecting sperms into eggs during the process of IVF to help in fertilisation of eggs. It is used in the cases wherein sperm count is low or sperms are too weak to penetrate the eggs on their own.
It’s not a separate process but a stage in IVF treatment. After going through semen analysis reports, the doctor decides whether the IVF process requires ICSI. It is generally used with severe male infertility issues wherein sperm count is too low, poor sperm morphology is reported, previous failed attempts of IVF on account of low fertilisation rate, sperms need to be collected surgically from the testicles or you are using frozen sperms.
The same procedure of IVF would be followed and the female partner would be put on ovulation inducing medication and continuous monitoring would be carried out to track the best time to retrieve the eggs from the ovaries. Once the egg retrieval is carried out embryologist will get ready for ICSI.
In order to carry out ICSI in an IVF process, embryologist pics up the best of the sperm from the produced semen sample, which with the help of a special needle, microscope, and other tools sperm will be injected in the inner part of the egg. If 3-4 eggs are collected through egg retrieval then sperm will be injected into each egg and then they will be closely monitored for next 2-3 days to see if fertilisation happens. Once fertilisation happens, then embryos will be further observed for 3-4 days before transferring 2-3 embryos to the womb. ICSI does increase the chances of fertilisation but doesn’t guarantee it.
