Women who have done IVF are concerned about what they can eat to improve their pregnancy rates, and today we’ll take a look at the latest epidemiological research advances in this area. 1, men are right to eat more chicken Recently, a prospective study from Harvard University found that the amount of poultry protein consumed by men was associated with successful assisted pregnancy outcomes. In the study, published in Fertility Sterility, researchers obtained dietary information on 141 men whose female partners had received assisted pregnancy interventions from 2007 to 2014. The results found that men’s poultry protein intake was significantly and positively associated with ART fertilization rates, while cured meat intake was negatively associated with fertilization rates in conventional IVF. However, none of these protein intakes were associated with ART embryo implantation rates, clinical pregnancy rates or live birth rates. The researchers noted that although the study is not currently supported by biological principles, it is the first study to find that men’s dietary habits are associated with assisted pregnancy outcomes. 2, women who want to get pregnant should eat more dairy products Another Harvard study focused on the relationship between women’s dietary habits and successful ART outcomes. The results found that women with a high intake of dairy products appeared to have a higher rate of live births after assisted pregnancy, and the study was published in Human Reproduction. Dairy products include cheese, cream, cow’s milk, ice cream and yogurt, and women who consumed greater than three or more servings of dairy products per day had a 21 percent higher live birth rate than women who consumed less than one serving, and this relationship was more pronounced in women over the age of 35. And the results remained the same regardless of whether the dairy products were high-fat or low-fat. However, dairy intake was not associated with other ART outcomes, such as fertilization rates and embryo quality. The researchers noted that this finding of this relationship in the population was unexpected based on previous studies noting that lactose intake appears to be harmful to fertility. 3, we all need to eat more deep-sea fish Recently, a small Australian study, targeting women who were overweight and obese and receiving ART, found that polyunsaturated fatty acid intake could significantly improve the success rate of ART, the results of which were published in the recent Nutrients. The study, which included 46 overweight obese women on IVF, 20 of whom were successful in pregnancy, found that daily intake of polyunsaturated fatty acids was significantly higher in those who were successful in pregnancy, particularly omega-6 polyunsaturated fatty acids and linoleic acid, which were strongly associated with pregnancy, while fatty acid intake was not associated with live birth rates. The study concluded that an appropriate increase in the proportion of polyunsaturated fatty acid intake in the diet may optimize the success of ART.
