ICSI (Intracytoplasmic Sperm Injection)
If you are diagnosed with male fertility problems, such as a low sperm count, previous history of vasectomy in the male partner, recurrent IVF failure then conventional IVF is unlikely to result in fertilisation. It is also done when sperms are not present in the semen and they have to be obtained surgically from testicles.This is when Intracytoplasmic Sperm Injection (ICSI treatment) is recommended. It is like IVF only the main difference is the technique we use to achieve fertilisation.
How is ICSI done?
A single sperm is injected into each egg, using very fine micro-manipulation equipment. As the human egg is one-tenth of a millimetre in diameter and the sperm 100 times smaller, this is a very delicate procedure performed by highly skilled embryologist under a micro-manipulator.
