When a diagnosis of male factor infertility has been made, ICSI in conjunction with IVF using the man’s sperm is typically recommended. ICSI is an enhanced fertilization method of selecting and injecting a single sperm cell directly into the egg.
ICSI is used during IVF to individually fertilize each egg for optimal results. ICSI is used to maximize the rate of fertilization and lessen the chances of sperm not being able to penetrate the wall of an egg.
- After the semen sample has been prepared, a single sperm is picked up into a tiny glass pipette under the guidance of a microscope
- The sperm is injected directly into an egg by passing the pipette through the surface of the egg
- The sperm cell is released into the egg and the pipette is withdrawn
- Simultaneously, a second polar body is released from the egg
- Egg Freezing
- Embryo Freezing and Frozen Embryo Transfer (FET)
- Ovarian Tissue Freezing
As with our other fertility preservation options, we freeze sperm using the vitrification process so there is almost no risk for damaging the sperm when it is frozen/thawed. In addition, by selectively thawing portions of the sperm, we can make one sample last for several IVF cycles. It can also be convenient for couples, making it no longer necessary to time the sperm collection with egg retrievals/fertilization procedures.
