With some cases of infertility, the problem may lie in the quality or numbers of sperm (male factor infertility). Either there are too few sperm to fertilize the eggs or there is poor sperm-egg interaction. Using ICSI, a single sperm can be injected directly into the egg.
Intra cytoplasmic sperm Injection
microinjecting an individual sperm cell into an egg for the purpose of fertilization
Intracytoplasmic sperm injection
Intracytoplamic Sperm Injection
A procedure where sperm is directly inserted into one egg.
Procedure injecting a single sperm into a single egg. close window
A procedure in which a single sperm is injected directly into an egg; this procedure is most commonly used to overcome male infertility problems.
lntracytoplasmic sperm injection
Intra- ytoplasmic Sperm Injection. An assisted reproductive technology procedure in which the superovulation and egg retrieval portion of an IVF procedure is performed first. Rather than allowing fertilization to occur by combining sperm and eggs in a petri dish as in IVF, a single sperm cell is injected into each egg to result in fertilization. ICSI is often used for males with compromised motility, which may prevent the sperm cell from penetrating an egg on it's own. Resulting embryos are cultured to a certain cell stage and then transferred as in an IVF procedure.
A procedure where sperm is injected into the egg in under a microscope to achieve fertilization.
The IVF technique where a single sperm is selected and directly injected into an egg.
