Intracytoplasmic Sperm Injection (ICSI)

Intracytoplasmic Sperm Injection (ICSI) was first introduced into clinical practice for certain types of infertility in 1992. It has revolutionized the treatment of severe male infertility.

At The London Women's Clinic we started offering ICSI in November 1994. ICSI involves the injection of a single sperm into each egg. The rate of fertilisation is generally between 65 – 70%.
ICSI is an invasive technique and uses sperm that would otherwise not be able to fertilise an egg. Concerns about the potential risks to children born as a result of ICSI have been raised and several studies have been published. To date, these studies involve relatively small numbers of young children. Nothing is yet known about risks to older children or the next generation.

One individual sperm is picked up in a tiny needle, many times smaller than a human hair. This sperm is then injected directly into the centre of a mature egg.
