The research, conducted by the u.s. National Institutes of Health in team with other institutions, has been made by studying laboratory mice. Published on the pages of the magazine ‘Science’, seems to open new avenues for the development of care innovative to counter the sterilità andé of anticoncenzionali brand new.
But also for the insights of some of the issues ‘pink’ as thepolycystic ovary. Ovulation is the release of a mature egg every month that is delivered alternately from one of two ovaries, thanks to a stimulus hormone.
Before the rupture of the follicle and liberation of the ovum, the cells that line the inside of the follicle begin to grow, take on a characteristic swollen, and begin to produce progesterone, under the stimulus of the pituitary hormone luteinizing, which favors the liberation of the egg from bonding to the follicle.
metà of the cycle, around the 14th day, the pituitary gland releases an increased amount; of luteinizing hormone, which causes the liberation of the ovum from the follicle, resulting in ovulation. But if they are turned off or inactivated genes that regulate the enzymes ERK1 and ERK2, the process – according to the results of the us study – stop since the spring, hindering the activitiesà of the luteinizing hormone. And, as a result, by stopping ovulation.
