ICSI and IVF are both highly effective treatment known for curing fertility issues. But though the process is rather similar and may overlap at times, there are some basic differences here. ICSI is the acronym for intracytoplasmic sperm injection. It means that the sperm is injected inside the egg. It is a simple and effective mode of fertilising eggs in the IVF lab, after the same has been taken from the female.
When combined together, IVF with ICSI makes use of specialized micromanipulation tools and equipment. Even inverted microscopes are used here, which help the embryologists for selecting or picking individual sperm with a state-of-the-art ICSI needle. The need is then taken through the outer shell of the membrane and egg and then inserted into cytoplasm or inner part.
As a result, normal fertilisation takes place. But the woman needs to have taken medications prior to this. Some use ICSI only for male infertility and some use it every time. Most IVF clinics opt for the middle path here. It works for people with sperm lower than 15-20 million per millilitre or poor motility issues. On the whole, these are the 3 main differences between the two-
- IVF means in-vitro fertilization and ICSI means Intra-cytoplasmic Sperm Injection.
- In vitro fertilization may be recommended in cases where other standard modes of reproductive technology are not viable. But in the case of ICSI, it is specially suggested for cases where inexplicable fertility problems tend to be there including the reasons mentioned above.
- In IVF the zygote results in minimal risks when it comes to carrying or posing a threat for genetic disorder. But with ICSI chances of chromosome disorder tend to be much higher
Hence, one would normally notice that many of the clinics tend to use both of these.
