A variety of techniques that can be performed in a laboratory under a microscope. An embryologist manipulates egg and sperm to improve the chances of pregnancy. (See also Intracytoplasmic Sperm Injection, ICSI.)
This term covers any technique used in IVF to bypass the zona pellucida (protein shell) which surrounds the egg, as this frequently prevents sperm which has poor motility or morphology from penetrating and fertilising the egg.ICSI is the most commonly used method of micromanipulation.
The IVF laboratory process whereby a single sperm is injected directly into the egg to facilitate fertilization, (ICSI) or the shell around the embryo is thinned to facilitate hatching (Assisted Hatching).
The use of a powerful microscope and remotely controlled fine instruments to manipulate gametes and embryos, e.g. to inject the sperm inside the egg in the laboratory (ICSI). Also used for Assisted Hatching and Preimplantation Genetic Diagnosis (PGD).
