This report provides an in-depth review of the existing literature on the relationship between maternal diet and fetal sex determination. It examines various studies and articles, exploring how a mother's nutritional intake before and during pregnancy can influence the sex ratio of her offspring. The report delves into the findings of multiple research papers, including those that analyze the impact of energy intake, specific nutrients like potassium, sodium, calcium, and magnesium, and the timing of sexual intercourse. It discusses the complex interplay of factors such as environmental conditions, stress, and the mother's overall health. The analysis also covers the methodologies used in these studies, including data from famine situations and prospective studies, while addressing the challenges in drawing definitive conclusions due to sample size limitations and the intricate nature of sex determination. The report highlights the current understanding of this topic, emphasizing the need for further research to fully understand the mechanisms through which maternal diet influences fetal sex.
