In a study of mice, scientists found that rodents with low blood-sugar levels — an indication of a sugar-rich diet — produce more female offspring, according to a report from the U. For the study, researchers gave 20 female mice a steroid called dexamethasone, which kept their blood-sugar levels low. The sex of their litters was then compared with that of 20 mice on a regular diet. Researchers, including Elissa Cameron of University of Pretoria in South Africa and published in the journal Proceeds of the Royal Society B, concluded that a diet that is high in sugary snacks may lead to more female offspring, in mice that is. Another researcher told New Scientist that research she has conducted also showed that diet can influence sex. Mace previously published a study that found mothers with more muscle mass are more likely to give birth to sons during food shortages. read more
