IMSI
Increased number of clinical pregnancies, fewer miscarriages
Intracytoplasmic Morphologically Selected Sperm Injection(IMSI) fertilization is a method involving the intracytoplasmic injection of morphologically and qualitatively selected sperm. It is the most modern method of IVF, currently giving the best results in terms of increased number of clinical pregnancies and lower miscarriage rates.
What is the IMSI in vitro fertilization procedure?
Immediately before the sperm is injected into the egg, the embryologist prices the sperm head under very high microscopic magnification.
AtGyncentrum Clinic, we use microscopes with the latest MSOME (motile sperm organelle morphology examination) technology. motile sperm organelle morphology examination), which allows analysis of the sperm under digital magnification of 6,000 times, which makes it possible to select the highest quality sperm.
Then, using a micromanipulator, a specially selected single sperm is implanted directly into the cytoplasm of the egg cell. The combined cells are placed for 2-3 days in an incubator, where conditions are very similar to those in the woman’s body. After this period, the embryos are ready for embryotransfer.
When is the IMSI method used?
IVF – IMSI method is especially recommended for couples with diagnosed male infertility factor:
- increased sperm DNA fragmentation
- for sperm retrieved directly from the testes or epididymides during the TESA/PESA procedure.
The IMSI method is also recommended for couples in whom previous IVF-ICSI procedures have failed.
