IVF- IMSI (In vitro fertilization- Intracytoplasmic injection of a morphologically selected sperm). IVF is the advanced technique which makes it possible to combine sperm and eggs in a laboratory for a baby that is genetically related to one or both partners.
It is often used when a woman's fallopian tubes are blocked. First, medication is given to stimulate the ovaries to produce multiple eggs. Once mature, the eggs are suctioned from the ovaries
(1) and placed in a laboratory culture dish with the man's sperm for fertilization
(2) The dish is then placed in an incubator
(3) About two days later, three to five embryos are transferred to the woman's uterus
Intracytoplasmic morphologically selected sperm injection (IMSI) is a specialized variation of ICSI that uses a higher-powered microscope to select sperm.
In conventional ICSI, the embryologist selects the most normal-looking motile sperm using a microscope that magnifies the sample up to 400 times. IMSI is a variation of ICSI that uses a high power light microscope (enhanced by digital imaging) to magnify the sperm sample over 6000 times. Sperms are then selected which have the most normally-shaped nuclei.
