This is typically an alternative option to traditional IVF and natural fertilization in the lab, and may be indicated in a number of situations. The procedure is used if there are not enough morphologically healthy and motile sperm cells in the semen, or when sperm are unable to independently penetrate the egg. The procedure involves injecting a pre-selected sperm into the egg.
The correct sperm cell is injected into the cytoplasm of the egg using special laboratory micropipettes.
Successful Rates
When choosing this method in situations of male factor issues, the chances of successful fertilization increase several times.
The most common indications for this assistive technology are:
- Male factor (with a significant decrease in sperm concentration, motility, and/or morphology);
- Use of surgically obtained sperm;
- Use of oocytes after cryopreservation;
- In vitro oocyte maturation programs.
