A new study showed that women who have physically demanding jobs can have reduced fertility. This problem can be experienced for women who work at night. Women who are overweight and also have physically demanding jobs tend to have even more problems when it comes to fertility.
The study showed that women who lift heavy object have 9% fewer eggs and 14% fewer mature eggs than women who don’t have physically demanding jobs. The researchers also focused on women who switch shift and who work at night.
The fact that women work on rotating shift can affect their health and can also decrease fertility. The study focused on women who have physically demanding jobs in order to see if their fertility is affected by their jobs.
“Our study suggests that women who are planning pregnancy should be cognizant of the potential negative impacts that non-day shift and heavy lifting could have on their reproductive health,” said lead author Lidia Minguez-Alarcon
The study also showed that women who are over 35 years old have a higher risk for decreased fertility. Another factor that can affect fertility is obesity. When it is combined with heavy lifting the fertility is decreased a lot.
In order to conduct this study, researchers analyzed more than 500 women who seek infertility treatment in the US. All of the women received treatment at Massachusetts General Hospital.
Despite the fact that the study showed there is a connection between physically demanding jobs, the researchers were not able to find out why these jobs affect fertility. The researchers mentioned that they did not figure out why lifting heavy objects affects the number and quality of eggs.
When it comes to working night shifts or rotating shifts, the researchers mentioned that fertility can be affected because of the circadian rhythm disruption. Although the researchers managed to find a connection between demanding jobs and lower fertility they need to make more studies on the topic in order to find a cause and effect.
The researchers mentioned that women who want to get pregnant should not have physically demanding jobs and they should work day shift. This way they can increase their fertility.
What is your opinion about this study? Did you know that lifting heavy objects every day can decrease fertility?
