IVF/ICSI | Olympus Life Science

Intracytoplasmic sperm injection (ICSI) is an in vitro fertilization technique in which a single sperm is injected into the oocyte cytoplasm using a pipette. Our inverted microscope system helps improve the quality of ICSI, which requires both speed and precision. With an optical system exclusively developed for ICSI, the microscope enables clear visualization of the spindle in a metaphase II oocyte through the oculars. Observing the spindle helps improve ICSI precision by confirming the oocyte’s phase of maturation and the position of the pipette injection to avoid damage to the spindle. The motorized unit also contributes to faster ICSI through its streamlined operation, helping alleviate stress on the oocyte. Optional differential interference contrast (DIC) observation units enable researchers to use intracytoplasmic morphologically selected sperm injection (IMSI) to confirm the shape, size, and number of vacuoles in the head of the sperm.
