Canadian and
European researchers have discovered the gene that regulates ovulation. The
gene, called Lrh1, has the ability to both regulate and block ovulation, they
said.
"We
discerned that this particular gene is absolutely necessary for the ovulatory
process," Bruce Murphy, director of the Animal Research Centre at the
Université de Montreal, told CBC News.
"The absence of this particular gene, in this particular cell in the ovary, had a global effect — it disrupted several processes which are necessary for the final event, which is ovulation."
Scientists then discovered the animals were not ovulating.
Murphy said that gene performs many functions. These include hormone balance, the preparation of the egg for ovulation, and the actual rupture of the ovarian follicle that releases the egg.
"A pharmaceutical could be developed to target this particular protein and either turn it on or turn it off," he said. "Turn it on to enhance fertility and turn it off if you want contraception."
The research team has been awarded a five-year grant to follow up on the discovery.
The study is published in the July 15 issue of Genes and Development.
