A New Study Has Found That Vitamin D May Increase The Chance Of IVF Success But It Depends On A Woman's Race. .

Vitamin D, also known as the 'sunshine vitamin', is famed for its benefit to bones and the immune system, but it also plays a role in conception.


Now, data suggests that the vitamin's benefits may only apply to certain racial groups - while white women can boost their IVF success rates with vitamin D, this doesn't appear to be true for Asian women. 



In vitro fertilization (IVF) is a popular option for couples struggling to conceive - it involves extracting eggs from a woman and fertilizing them with sperms outside of the body. The resulting embryo is then transferred into the uterus. 

To find out whether vitamin D carries the same benefits in women of different races,it has been compared ; vitamin D levels and IVF success rates in white Hispanic, white non-Hispanic, and Asian women from south-east Asia and the Indian subcontinent. 

All 188 women included in the study were having IVF for the first time. 

Of these women, only 42 percent had the recommended levels of vitamin D - just over a third had insufficient levels, while a fifth were completely deficient. 

The researchers found that white women who were vitamin D replete were four times more likely to have a successful pregnancy as compared to women of the same race who were deficient in the vitamin. 

Unexpectedly, the reverse was true for Asian women as those with the lowest vitamin D levels were most likely to get pregnant. 

Even though the team aren't sure why these differences exist, they think it might have something to do with the enzyme that deactivates vitamin D. 

According to them, there are also ethnic differences in the gene for the vitamin D receptor, which may affect the link between vitamin D and conception. 

The study has been published in the journal Human Reproduction.

Egg Producing Cells That Survive Cancer Treatment may prevent Infertility..A New Study Shows :

In a finding that could prevent infertility among women who undergo treatment for cancer, researchers have identified new egg-producing cells that can survive the radiation caused due to cancer treatment.

The findings by researchers from Melbourne could pave the way for a course of injections or tablets able to protect women's fertility within a decade


The proteins, known as PUMA and NOXA, trigger death in damaged cells in the ovaries.

Researchers established a way to prevent the proteins reaching the damaged cells, thereby keeping the cells alive.

They were also able to show for the first time that the cells were able to repair the damage caused to their DNA by cancer treatment - and go on to produce healthy offspring.

The study has been published in the journal Molecular Cell.
