Allergies Not Reduce Women’s Fertility

Women with asthma, hay fever, or allergic dermatitis known to be less fertile than women who do not suffer from allergies, and even they may be more likely to be able to conceive.

This is an important discovery for women allergy sufferers and the doctors. The study was conducted by researchers from the University of Nottingham and the results reported in the American Journal of Epidemiology.

Researchers note had been known that the second child and so have a lower risk for asthma or other allergic diseases. One likely explanation is that women who have allergic disease may be less fertile so rarely that have many children.

To investigate about this, the researchers conducted a study to compare the fertility rates in 491 516 women aged 15 to 44 years, over a period of 10 years. As many as 13% of respondents with asthma, 14% suffer from allergic dermatitis (eczema), and 12% suffer from hay fever. While 6% had two symptoms, and 1% had three.

The researchers found no significant differences between women with asthma and without asthma, although people with asthma who were in their 20s and even slightly more fertile than others.

The researchers also do not know how allergies can increase fertility, allegedly due to the balance of certain cells in the immune system that are in a state of allergy triggering conception.

The study results strengthen the evidence that the fertility rate of women with asthma, eczema, or hay fever is not less favorable than other general population.
