Brain Protein Holds Key To Fertility

Scientists have discovered the crucial ovulation-triggering role played by a small protein molecule in the brain, a finding that could hold the key to new therapies for infertility.
Dubbed kisspeptin, the protein is known to play a vital role in kick-starting puberty.

Now, a group from the University of Otago led by Professor Allan Herbison, in collaboration with Cambridge University researchers, has published the first evidence that kisspeptin signalling in the brain is also essential for ovulation to occur in adults.
