The appearance of intra-cytoplasmic sperm injection in 1992 was a milestone in the field of assisted reproduction since it enabled many men whose semen was of low quality and who had previously had to resort to a donor to be a father could benefit from this technique.

Nowadays, the development of this technique makes it possible to solve almost any male problem, since no matter how few spermatozoons there are and regardless of their origin (ejaculated, directly from the testicle, epididymis, etc.), they can be used to have children. To perform this technique, the ova need to be extracted via in vitro fertilisation and injected under a microscope in the laboratory.
