Gene work may prove fruitful for ending human fertility problems
Scientists have identified a gene which could help cure infertility in humans.
The University of Edinburgh team conducted a study with fruit flies, during which they found that when the gene SRPK is missing, chromosomes do not "huddle" together.
They believe the huddling process is necessary to ensure the egg's healthy development and fertilisation.
Chromosomes are thread-like structures which contain a person's DNA, and when they divide it can lead to sterility and low fertility, according to the study.
By identifying the genes involved in the process, the experts now hope to understand what goes on in the creation of fertile reproductive cells.
The team said further research is needed to help build a more detailed picture of how huddling works.
