Natural Antioxidant Linked To Fertility In Women


A natural antioxidant found in nuts, read meat and seafood could help increase a woman’s chance of conceiving, according to a study conducted by the University of Adelaide.

Selenium, which plays a crucial role in the early stages of conception and in the development of healthy ovarian follicles, frequently occurs in Brazil nuts – in fact, the nut has the highest level of selenium than in any other food.

“It is important for many biological functions, such as immune response, thyroid hormone production, and acts as an antioxidant, helping to detoxify damaging chemicals in the body,” Melanie Ceko, a researcher in the study, said.

Ceko added that researchers have long known that selenium is important for the fertility of men, but that until now no one has researched its role in women’s fertility.

In the study, researchers noted a protein in the ovary that contained a high level of selenium, called GPX1. In many cases, eggs that yielded a pregnancy had double the levels of GPX1 in them.

"Our findings are important, because they show that selenium and selenoproteins are at elevated levels in large, healthy ovarian follicles,” Ceko said. “We suspect they play a critical role as an antioxidant during the late stages of follicle development, helping to lead to a healthy environment for the egg,"

Scientists cautioned against the excess intake of selenium, noting that too much of it can be toxic. They also noted that further studies should be made to better understand of selenium levels can help women conceive.

Selenium can be found in Brazil nuts, seeds, seafood like tuna and swordfish, whole wheat bread, red meat, mushrooms and whole grains like rye.
