Process step by step
The ICSI process step by step is as follows:
Ovarian stimulation & egg retrieval
A series of hormones are administered so that the woman’s ovaries produce more than one mature oocyte. Moreover, this hormonal supplement also helps controlling the exact date when the menstrual cycle will start.
Sperm collection & preparation
A lower amount of sperm than IVF is required for ICSI, since it will be the biologist who, by means of a microscope with a micromanipulation system, will choose the ideal spermatozoon. If there are too many spermatozoa in the sample, it is counterproductive because it makes it more difficult to choose the one which is going to be injected.
Oocyte insemination & embryo culture
The ideal sperm is chosen and then the ICSI process is conducted. The spermatozoon is inserted inside the oocyte with a needle.
Then, embryo development is evaluated and recorded.
Embryo transfer & vitrification
If more than a single healthy embryo exists, it is frozen in order to be used in further treatments.
