Male Fertility Kick Starts With Missing Sperm Protein, Cardiff University Study

Male infertility can be the result of sperm missing just one vital protein, which is necessary to activate the egg when the sperm fuses with it. But injecting that egg with the missing protein can "kick-start" the vital processes of embryo development, and dramatically increase the chances of a successful pregnancy. These are the findings of a new study by a team at Cardiff University in the UK who write about their work in a paper being published in the journal Fertility and Sterility. They suggest the findings strengthen the case for the potential use of the protein in treating male infertility.
