Intracytoplasmic Sperm Injection (ICSI) was first introduced into assisted conception technology in 1992 and has revolutionized the treatment of severe male infertility.
ICSI is a carried out under specialised microscopes by individuals well trained in embryology, whereby one individual sperm is picked in a tiny needle, which is many times finer than a human hair. This sperm is then injected directly into the centre of a mature egg which are obtained at the time of egg collection during a woman’s IVF treatment cycle. Fertilisation rates following ICSI are variable and range between 65 to 85%.
ICSI is required for sperms that would normally not be able to fertilise an egg naturally or during IVF treatment.
