A well-balanced diet can improve your chances of conception. Indeed, nutrition and fertility are so strongly correlated that a well-balanced diet is actually considered an effective treatment for infertility in both men and women. Men who consume a healthy diet have higher quality semen and improved conception rates. Moreover, good nutrition can reduce the risk of fertility problems ever developing in the first place.
Weight impacts Fertility
In contrast, excess weight can negatively impact fertility and obesity causes infertility. If you or your partner are overweight or obese, you should consider following a fertility diet plan. In fact, reducing your calorie intake (by limiting fat and carbohydrate intake) and increasing your aerobic exercise can significantly improve your chances of conception
Several studies have shown that women who follow a good diet and exercise regimen are more likely to get pregnant, while the same strategies in men lead to better sperm quality.
Nutrition for conception: the Mediterranean diet
The Mediterranean diet is known as the “fertility diet” because unsaturated fats, whole grains, vegetables, and fish are associated with improved fertility in both women and men. It includes high consumption of:
- fruit and vegetables
- fish and chicken
- legumes
- whole wheat
- olive oil
German guidelines also recommend consumption of whole grains, fruits, vegetables, unsaturated oils, meat and fish before pregnancy. Conversely, eating too many fats and red meat can delay conception.
Components and foods to help fertility
Because a good diet is so essential for fertility, it is important to know which foods and nutrients can help promote pregnancy. Let’s look at the role of different “fertility diet” elements in more detail.
Carbohydrates
Carbohydrates and sugar affect glucose levels and insulin sensitivity. These can interfere with the ovarian production of androgens and with ovarian function in general. Numerous studies have shown that reducing carbohydrate intake can improve ovarian function in women with Polycystic Ovary Syndrome.
Omega-3
A diet rich in omega-3 derived from fish, dried fruit, oil seeds could improve male fertility and reduce the time to pregnancy. The American College of Obstetricians and Gynecologists (ACOG) encourages women who are trying to get pregnant to consume two or three servings of fish per week.
DHA (Docosahexaenoic Acid), a particular type of omega-3 fatty acid, is essential for healthy sperm in men. DHA is also important for women before, during and after pregnancy, as it supports reproductive functions.
Vitamins
Vitamins are essential for the body to work properly and they support several biochemical processes. A diet for fertility and pregnancy should include vitamins like:
- Vitamin C
- Vitamin B12
- Vitamin B6
- Vitamin K
- Vitamin D
Vitamin B6, or Folic Acid, is especially important in nutrition for conception because it is involved in the synthesis of DNA, a key building block involved in fertilization and pregnancy. Many studies have explored the association between fertility and folic acid supplementation and results show that folic acid supplementation lowers a women’s risk of anovulatory infertility and reduces the time to pregnancy.
Amino Acids
- Amino Acids are the primary structural units forming the long sequences that produce proteins. While there are more than 500 different types of amino acids, 20 are essential for humans
- L-carnitine is an amino acid produced from two amino acids Lysine and Methionine and it is mainly synthesized in the liver and kidneys. It is one of the most important amino acids for diet and male fertility because it provides sperm with fatty acids that ensure the right energy to fertilize the egg
Minerals
Mineral salts also play an important function in all living organisms. They are involved in the formation of teeth and bones, the growth and development of tissues and organs, and numerous metabolic processes, including both the male and female reproductive system.
Since our body cannot produce minerals independently, we can only get them through food and water. Consumption of macroelements such as magnesium, calcium, phosphorus, and potassium is important for the support of several bodily functions, including reproductive ones. In particular, male fertility is enhanced through the intake of zinc, selenium and L-carnitine.
What to avoid in the diet
Alcohol can have a negative impact on fertility, embryo quality and conception. Women who are trying to conceive should also limit caffeine as an association has been found between coffee intake and miscarriage risk. Smoking also has a detrimental effect on both for the quality of female ovulatory cycles and the quality of the male semen.
Diet for women with polycystic ovary syndrome
Women with Polycystic Ovary Syndrome (PCOS) may be at a higher risk of developing metabolic problems, such as diabetes. Therefore, it is important to plan a specific diet for PCOS, which is designed to control glycaemic index and promote weight loss or a healthy weight.
Here are some recommendations for a PCOS fertility diet:
- take an adequate amount of fiber
- reduce simple sugars and control the intake of complex carbohydrates
- reduce fat intake, especially saturated fats
- avoid frying and choose cooking methods such as: steaming, microwaving, grilling or pressure cooking
- never skip breakfast
More than diet to support fertility
While nutrition is a very important factor for improving your chances of getting pregnant, it is not enough. A healthy lifestyle should also include exercise and physical activities and strategies for improving emotional well-being, such as mindfulness.
