Boys Born To Older Women May Have Heart Disease At Old Age : Study

Scientists at the University of Alberta in Canada, have alerted that boys born to older women were more likely to develop Cardiovascular disease (CVD) later in life. Also, the researchers said in animal experiments, males born to older female rats, equivalent in age to a woman of 35, had weaker hearts and blood vessels.
To this end, future studies, will look into whether or not the findings were true in humans, said Professor Davidge, adding that a particular focus would be the role of the placenta.
The findings of the new study were published in the ‘Journal of Physiology’. Although, previous studies had shown that delaying motherhood was already known to increase the risk of complications in pregnancy. However, going by the new research, scientists have found that the growing trend of putting careers ahead of starting a family could have an even bigger impact on future generations than feared. Cardiovascular disease (CVD) is a class of diseases that involve the heart or blood vessels.
They include coronary artery diseases (CAD) such as angina, myocardial infarction (commonly known as a heart attack), among others. According to the American College of Obstetricians and Gynaecologists, Fertility in women starts to decrease at age 32 years and becomes more rapid after age 37 years. Women become less fertile as they age because they begin life with a fixed number of eggs in their ovaries, which begins t decreases as they grow older including diabetes mellitus or gestational diabetes.
The research team said the new study demonstrated that postponing parenthood makes offspring more prone to cardiovascular disease as adults. However, female offspring did not suffer the same effect. Lead researcher Professor Professor Sandra Davidge Sandra said: “This research is important because it improves our understanding of the impact of giving birth at an older age.”
