Description
After the first infant was born using IVF in 1978, this method was used widely for infertility treatment. Because, in male infertility, most of the time sperm is not able to fertilize the ovum, a number of complementary ways developed to overcome this deficiency; these ways are called “aided fertilization”, “fertilization with microscopic surgery” or “absolutely microscopic manipulation”. The use of microscopic manipulation of human gametes not only leads to fertilization with a low number of sperms but also deficient sperms can be used for egg fertilization this way. Currently using different methods of microscopic manipulation, we’re able to recognize genetic deficiencies and even repair them. Also, this method increases the number of embryo implantation in different cases.
