Sarah Norcross Director of fertility and genomics charity PET said:
This is a significant step in establishing whether sperm created in the lab could, one day, be used for human reproduction. We will be watching closely as the researchers carry out this work in macaques, first seeing whether eggs fertilised with this type of sperm can lead to a pregnancy, and then seeing whether a pregnancy can be achieved with sperm derived from skin cells. Even if all of these things are achieved in macaques, it will still take many years and much more research before such techniques are fit for use in human treatments.
