Women working night shifts may find it harder to fall pregnant


Screen Shot 2017-02-09 at 11.57.18 AM For the study 473 women with an average age of 35 undergoing fertility treatment were examined. The females who worked during the night had 24 per cent fewer mature eggs, the eggs needed for turning into a healthy embryo. Another possible fertility problem highlighted in the research is that ladies whose job involves heavy lifting have 14 per cent fewer mature eggs. Immature eggs turn into mature ones in the lead up to a women’s ovulation, with some becoming mature each month thanks to certain hormones. The process sees the chromosomes in the egg slashed from 46 to 23, the number required to form an embryo. The number of eggs that mature is affected by the hormone surge, with factors including not getting enough sunlight and physically demanding activity directly impacting the hormones. This can lead with trouble falling pregnant. To get their results researchers artificially triggered the ovulation of several eggs, ready for IVF treatment. “These findings have clinical implications, as women with fewer mature oocytes (eggs) would have fewer eggs which are capable of developing into healthy embryos,” the study authors said. They add their study is observational, and results do not mean women who work in jobs like this can’t conceive, it just might take longer or they may need IVF. Results have been published in the Occupational & Environmental Medicine journal. © Cover Media
