New relief for gynecological disorders
Date:4/3/2013

The creation of new blood vessels in the body, called "angiogenesis," is usually discussed in connection with healing wounds and tumors. But it's also an ongoing process in the female reproductive tract, where the growth and breaking of blood vessels is a normal part of the menstrual cycle. But abnormal growth of blood vessels can have painful consequences and resultant pathologies.

Now, Prof. Ruth Shalgi and research associate Dr. Dana Chuderland of Tel Aviv University's Sackler Faculty of Medicine have found a potential treatment for this abnormal growth in a potent physiological anti-angiogentic factor, PEDF. Administered by simple injection, this protein reverses the symptoms of related diseases without compromising fertility, according to pre-clinical studies.

These new findings, which have been reported in the Journal of Clinical Endocrinology and Metabolism, Human Reproduction and Molecular Human Reproduction, could provide relief for millions of women worldwide. This work was done in collaboration with Prof. Rafael Ron-El and Dr. Ido Ben-Ami from Assaf Harofeh Hospital.

Dangers of angiogenesis

There are two primary pathologies associated with angiogenesis in the female reproductive system. One is endometriosis, characterized by the passage of uterine cells to other locations in the body during menstruation, which causes severe pain and reduced fertility. The other is ovarian hyperstimulation syndrome (OHSS), a possible side effect of IVF treatments. This is a potentially life-threatening disease with symptoms including abdominal pain and swelling.

Approximately 170 million women suffer from endometriosis worldwide, and about 10 percent of women receiving IVF treatment develop OHSS. Because no treatment currently exists for either of these conditions, affected women have no choice but to suffer through the symptoms.

In the past few decades, scientists have conducted extensive research
