What Is Artificial Sperm?

Artificial sperm is not artificially made sperm. It is just that the human spermatogonial stem cells are extracted using scientific techniques, cultivated into sperm in an external environment, and finally combined with eggs to complete the process of fertilization.

Addressing infertility

From the perspective of developmental biology, infertility may be caused by abnormal egg development or abnormal sperm development. "Artificial sperm" is helpful to correct and make up for defects in sperm development. In theory, it can be done in vitro

The most mature spermatozoon technique than artificial sperm

Artificial sperm

A research team from the University of Newcastle, UK announced and published this breakthrough in the internationally renowned academic journal "Developing Cells". The research was led by biologist Karim Nayenia, who previously successfully used mouse stem cells to cultivate sperm for observation under a microscope. This artificial sperm is similar to normal human sperm, with a head and tail that can swim. move. Nayenia says they also have proteins and chromosomes unique to normal sperm.

Nayeniya said this is a group of "fully mature and practical" sperm that can bind to human egg cells and eventually develop into embryos.

The artificial sperm revolution has not yet succeeded

Of course, the advent of artificial sperm is not only controversial but also questioned by the scientific community. Some scientists have expressed doubts about the achievements of British scientists. Dr. Allen Passy, senior lecturer in medicine at the University of Sheffield, said: "As a scientist who studies sperm, I have more than 20 years of experience, and I cannot draw their conclusions from their public data. The cells isolated from embryonic stem cells can be called sperm, and those cells that are cultivated may have some genetic characteristics, but they are very different in function and molecular structure from sperm. "

Some scientists have even pointed out that artificial sperm have serious defects, and women who "produce" themselves are all baby girls. Because female cells lack the Y chromosome that is necessary to have a boy, all offspring born from female "artificial sperm" will be baby girls. Both males and females have 23 pairs of chromosomes, of which 22 pairs are the same, and the 23rd pair of male chromosomes are X and Y chromosomes.
