Surprisingly the month one is born does affect one’s fertility rate. Those women who are born during the summer tend to have fewer children than those women born at other times of the year.
Women born in July had 13% fewer children than women who have birthdays in December. Researchers feel that maternal nutrition along with weather conditions can affect fetal development at a critical stage.
In July rainy season the fertility rate is higher as compared to January. The lower birth rate of a January woman is indeed linked to the crucial third month of one’s fetal development. Poor nutrition or increased infection in mothers added to difficult weather conditions can affect the fetus.
As far as men are concerned, autumn does affect fertility as they tend to produce fewer children and in spring their fertility rate of producing more children goes up. Again fetal development conditions are likely to be of much importance.
Effects of Weather on Fertility:
Monthly temperature does affect fertility and there are seasonal and non-seasonal variations in monthly births. There is much significant seasonality in births in every population that one comes across and no doubt weather influences conception. It is understood that summer heat depresses conceptions. In Northern Europe, during spring time there is a peak in births. Weather does quantitatively influence both the seasonal and non-seasonal variation in births.
Global temperatures will increase by anywhere from 5 to 10 degrees Fahrenheit (3 to 6 degrees Celsius) in the coming century if we continue on our path of greenhouse gas emissions. Climate change does affect fertility which is an important economic concern.
Links between Temperature and Fertility
How does global warming affect fertility in two key ways?
Hot weather does affect sexual behavior. Physically demanding activities are more difficult at high temperatures.
Temperature could also negatively influence reproductive health factors such as sperm motility and menstruation.
The hypothesis is that global warming might indeed be a threat to human reproduction, something that had yet to be thoroughly investigated by scientists as well as policymakers.
Hot Days and Conception Chances
Hot days do cause a reduction in birth rates.
Sexual behavior does get influenced by hot weather. Reproductive health is rather vulnerable in hot weather. Making sex is rather uncomfortable in hot weather.
Fertility Costs of Climate Change
Developing countries do face the effects of climate change, which does affect fertility. Infant health also is exposed to hot weather.
Air conditioning can offset some of the negative effects of hot weather, although it may also exacerbate the climate change.
It is but obvious that seasonal changes do affect the birth rate and birth man’s and woman’s fertility rates are also influenced by changing weather patterns. To conceive in summer is difficult as couples tend to indulge less in sexual activity due to hot weather conditions.
Sperm increase much depends upon weather as it decreases significantly from spring into summer and fall and rebounding in the winter. The physical structure of the sperm cells was also the healthiest in the winter months. Changing weather is somehow related to the quality of sperm. Sperm quality changes according to weather.
The rate of fertility does get influenced by changing weather patterns and sexual activity is also influenced by such changing patterns.
