Intra Cytoplasmic Morphologically Selected Sperm Injection (IMSI)
This method is one the IVF laboratory technique at which the sperm is directly inserted into the egg. Before performing the microinjection, a high quality sperm is selected first. The sperm selection process is performed with the help of a microscope which has highly magnifying power compared to the normal instruments used in ICSI.
A very high power microscope is used to magnify the sperm around 7000 times. In this process, the specialist discards the abnormal sperm and a sperm without any minute abnormality is selected, as it increases the success rates and decreases the risks if miscarriage. The pregnancy rates in this process were increased by 20% compared to the ICSI process. IMSI is the advanced development for male factor infertility.
IMSI is recommended for patients with:
- Tubal blockage or severe tubal damage
- Ovarian failure (NO PERIODS),
- Severe male factor infertility (less than 5 million/hpf)
- Advanced stages of endometriosis in women over 40 years old
- In couples with a long duration of infertility (over 5 years)
