Tissue Reimplantation

Helps Woman Conceive

In a medical first, a 25-year-old cancer patient has conceived a baby after her ovarian tissue was removed, frozen and then reimplanted, according to reports released yesterday.

Doctors from the Catholic University of Louvain in Brussels froze ovarian tissue from the unidentified woman before she had chemotherapy treatment for Hodgkin's lymphoma. She is now 25 weeks pregnant.

The advance, which gives new hope to other young cancer patients whose fertility may be damaged by treatment, was reported at the annual meeting of the European Society for Human Reproduction and Embryology.

Jacques Donnez and his team "have managed to achieve what no other team in the world has yet been able to do -- given a young woman, who underwent cryopreservation of ovarian tissue prior to treatment, the gift of pregnancy," the university hospital said in a statement.

The scientists are to present their research at the society meeting, and the research is to be published in a peer-reviewed journal, a university spokesman said.

The baby was conceived naturally and is due in October.

Other teams of scientists have been working on similar techniques, but the Belgian team said it is the first to achieve a pregnancy.

The woman's ovarian function was restored four months after the ovarian tissue was transplanted.

Overweight Girls Who

Diet Tend to Gain More

Girls who are starting to get too fat at age 5 are often experienced dieters by age 9, but put on extra fat instead of taking it off, U.S. researchers said yesterday.

They said their study shows that children and their parents are well aware when they weigh too much, but they do not know the best ways to slim down.

Jennifer Shunk and Leann L. Birch of Pennsylvania State University studied 153 girls living in central Pennsylvania. Those who weighed too much tried to diet but ended up putting on more weight, they wrote in their report, published in the Journal of the American Dietetic Association.

The unhappier the girls were with their weight, the more they tried to diet, but they failed. This supports other research that shows "youths' attempts at weight control may promote weight gain," Shunk and Birch wrote.

At age 5, 32 of the girls were considered at risk of being overweight by Centers for Disease Control and Prevention standards.

They were checked again at ages 7 and 9. At 7, girls at risk for being overweight were eating significantly more than those not at risk, the researchers wrote.
