The IMSI Technique (Intracytoplasmic Morphologically Selected Sperm Injection) is an enhancement method used in IVF treatments that allows for detailed examination of sperm by magnifying it. In routine microinjection procedures, sperm is magnified by 200 times under a microscope, while the IMSI method can magnify it up to 8,000 times. This enables the detection of various structural problems in the sperm and increases the rate of healthy embryo formation.
Scientific studies have shown that IMSI leads to better embryo development, higher pregnancy rates, and reduced rates of pregnancy loss. Particularly in the following cases, the IMSI Method emerges as an important adjunct tool that can be used to enhance success:
When a problem is detected related to sperm
In cases where there are quality eggs but pregnancy doesn’t occur
In cases of recurrent miscarriages
In cases of unexplained infertility
In patients who have experienced failed IVF attempts
In cases of low egg count
The PICSI technique (physiologic intracytoplasmic sperm injection) operates on the same principle as IMSI, using a specialized binding medium for sperm selection. It is used for the same indications as IMSI and serves as an effective sperm selection method to increase pregnancy rates and reduce miscarriage rates.
