ICSI, which stands for intracytoplasmic sperm injection, is a procedure developed in 1992 in which a single sperm is injected directly into an egg using a fine needle. Unlike conventional In Vitro Fertilisation (where the sperm and egg are incubated together to allow fertilisation to occur), IVF with ICSI achieves fertilisation through direct sperm injection.
ICSI can only be performed when the eggs are mature, meaning, when they are at the optimal moment for fertilisation. This represents only a portion of the total eggs retrieved in a cycle. There are poor-quality eggs that are damaged at the time of sperm injection.
From the good-quality eggs, fertilisation is usually achieved in about 70 % of cases.
The results of embryo quality in ICSI and conventional IVF are usually comparable. Some experts believe that manipulation of the egg can alter embryo quality. However, this risk is minimal when performed by an expert biologist.
Yes, if the quality of the embryos is comparable.
In cases of severe male factor infertility, before performing IVF with sperm microinjection, it is important to conduct a study of testicular meiosis to rule out genetic abnormalities in the sperm that could lead to repeated failures in achieving pregnancy or embryonic abnormalities. In some cases, if there are enough spermatogenesis cells, this study can be done on the sperm
