Intracytoplasmic Morphological Sperm Injection

IMSI (Intracytoplasmic Morphological Sperm Injection) is a technique used in the field of assisted reproductive technology (ART), specifically in IVF (In Vitro Fertilization). IMSI is a specialized form of Intracytoplasmic Sperm Injection (ICSI), where a high-resolution microscope is used to select sperm with the best morphology (shape) for fertilization.

During IMSI, a single sperm is carefully selected and injected into the egg, using a micromanipulation technique. Thehigh magnificationof the microscope allows embryologists to select sperm with a more regular and symmetrical shape, which has been shown to increase the chances of fertilization and improve the chances of a healthy pregnancy.

IMSI is typically used in cases where male factor infertility is present, such as low sperm count, poor sperm motility, or abnormal sperm shape. It is also used in cases where previous IVF/ICSI cycles have failed, or in patients with high levels of DNA fragmentation.

It is important to note that while IMSI may have potential benefits, it is not a guarantee of success and individual results may vary. Patients should discuss the potential risks and benefits of IMSI with their fertility specialist to determine if it is an appropriate option for their particular circumstances.
