First artificial spermatozoon has been created by scientists at Newcastle University, Great Britain. During this experiment male and female stem cells were utilized to develop a fully-fertile spermatozoon. While female stem cells never produced a male gamete, the same attempt with male cells turned out to be a success.
According to scientists, although the artificially-generated spermatozoon lacks mobility and may fail whenever an ovule is encountered, it possesses qualities of its natural prototype and is capable of fertilization.
Scientists think, this finding may signify a breakthrough advance in infertility treatment which may implement artificial spermatozoon within 10 year time already.
