Intracytoplasmic sperm injection
Intracytoplasmic sperm injection or ICSI (intracytoplasmic sperm injection) is a technique of assisted reproduction that consists in the fertilization of oocytes by injection of a sperm into their cytoplasm by means of a micropipette, after obtaining and preparing the gametes for the purpose of to obtain embryos that can be transferred to the maternal womb.
