A groundbreaking study led by researchers at the University of South Australia sheds light on the long-term health implications for males born to obese mothers. According to their findings, these individuals are not only more likely to be overweight at birth but also face heightened risks of developing metabolic complications later in life, such as liver disease and diabetes.
The study, focused on fetal liver androgen signaling, highlights the role of male sex hormones in shaping the development of male fetuses. Dr. Ashley Meakin, a researcher at UniSA, explains that excessive activation of pathways in the developing liver by these hormones can lead to an imbalance, favoring growth over health.
Dr. Meakin emphasizes the importance of maintaining a delicate balance of androgens during pregnancy, as an overabundance can result in excessive fetal growth, posing risks not only during birth but also affecting liver function in adulthood. Interestingly, female fetuses exposed to excess testosterone from maternal obesity exhibit a different response, effectively shutting down the androgen pathway in the liver, thereby reducing the risk of metabolic disorders in adulthood.
Professor Janna Morrison, lead author of the study, underscores the crucial role of maternal nutrition during pregnancy in shaping the future health of the offspring. She stresses the need for a shift in societal attitudes toward nutrition to combat the rising tide of obesity-related health issues, starting from prenatal care.
In the interim, Dr. Meakin suggests that nutritional supplements addressing maternal imbalances could offer a promising avenue to support optimal fetal development.
The liver androgen signaling study, recently published in Life Sciences, is part of a broader research initiative by Prof. Morrison and her team exploring the impact of maternal nutrition on various aspects of fetal development, including the placenta, heart, lung, and liver.
