In Vitro Fertilization or IVF is a technology in which eggs cells are fertilized by sperm outside the body. Eggs removed from the woman’s ovaries after hormonal stimulation are fertilized by washed sperm – spermatozoa removed from the other components of seminal fluid. The egg and sperm are combined in a fluid medium inside a special cultivation dish in an incubator.
ICSI is recommended to choose the best sperm to fertilise the egg, thereby minimising the risk of an unhealthy embryo.
Intracytoplasmic Sperm Injection or ICSI is a micromanipulation procedure that involves the careful selection of high-quality well-formed sperm with good motility. Using a microscope, a micro-pipette first immobilises a single sperm by cutting its tail with its point. The spermatozoa is then injected into the egg cytoplasm.
ICSI is designed to make fertilization more effective, thus improving IVF success rates. For couples who have trouble conceiving for inexplicable reasons like repeated ivf failure, this procedure can also be a possible option.
