Protein implants bring hope to infertility

According to a new study in the UK, transplanting a missing protein into sperm of infertility can help bring fertility and significantly increase the rate of successful conception.

In a statement, Cardiff University said its researchers found that sperm introduced an important protein called P LC-zeta (PLCz) into eggs during fertilization.

This protein initiates a process called "egg activation" that opens up the entire biological process necessary for embryonic development.

Professor Tony Lai at Cardiff University stressed: "We know that some infertile men are because their sperm cannot activate eggs. Even if their sperm has access to eggs, it is not possible. What happens that those sperm may be missing a PLCz version with proper functionality. "

"In the laboratory, we were able to prepare a strong human PLCz protein. When a non-fertilized egg is implanted with human PLCz, it responds properly to natural conception, helping the embryo develop into merits to the blastocyst stage ".

Lai added that although this is only a laboratory study and cannot apply their method in a maternity unit, this progress is likely to apply to people.

In the future, "we can produce PLCz people and use it to stimulate egg activation in a completely natural way".

Research by Professor Lai and his colleagues was published on the website of Fertility and Sterility on September 21.
