At the conference of the European society of human reproduction and embryology (ESHRE), held recently in Geneva, was the study that gave rise to optimism among the experts in the field of reproductive medicine. In these studies, we consider two problems that prevent women to get pregnant. Previously they were considered intractable, however, for the first time researchers have been able to cope with them, writes the correspondent of the newspaper «gaarets» IDO Efrati.
The first problem, known as asherman’s syndrome mainly occurs as a result of complications from surgical interventions in the area of the uterus. This disease is characterized by the development of uterine cavity adhesion processes, which deform and constrict its lumen. Because of this, the fertilized egg can not attach to the uterine wall.
The second problem is called premature ovarian insufficiency. It is characterized by the fact that the woman ahead of time menopause comes, the ovaries cease to produce eggs.
Professor Carlos simón, Spanish expert who heads one of the world’s leading groups on the study of asherman syndrome, treated 18 women who had discovered this problem.
The proposed treatment was based on stimulating stem cell production in the bone marrow from where they enter the bloodstream, and then filtered and by means of a catheter introduced into the uterus.
According to the study, two months after treatment, 17 patients had significantly improved the condition of the endometrium. Six months later the three women were able to conceive.
A study on the premature failure of the ovaries, was performed in Japan with the participation of specialists from Stanford University in California.
In the study, the woman had removed one ovary. Ovarian tissue was cut into small strips, which were placed in the substance known that it stimulates the maturation process of oocytes. These stripes are then transplanted back to the place where the ovary near the fallopian tube. Strips caught on and began to function properly.
Patients were also undergoing hormonal therapy, and they have removed the egg, as is done with conventional in vitro fertilization. As a result, three women were able to conceive, and two of them gave birth.
If new studies can prove the effectiveness of this method, it may allow women with premature ovarian failure to become pregnant without using donor eggs.
