Many couples trying to conceive wonder if certain foods like boiled eggs can help boost fertility. Eggs are a good source of many vitamins and minerals that are important for reproductive health. However, the impact of boiled eggs specifically on fertility is unclear. This article will examine the evidence on boiled eggs and fertility and provide some tips for including fertility-boosting foods like eggs in your diet.
Are eggs good for fertility?
In general, eggs are considered a fertility superfood due to their nutritional content. Here’s an overview of the key nutrients in eggs and why they matter for fertility:
| Nutrient | Function |
|---|---|
| Protein | Needed to support ovulation and develop a healthy egg and embryo. Helps balance hormones. |
| Vitamin D | Linked to higher pregnancy rates in women undergoing IVF. May help improve menstrual regularity. |
| Vitamin B12 | Needed for red blood cell production and DNA synthesis in eggs. Deficiency linked to infertility. |
| Folate | Critical for DNA replication and cell division in eggs and embryos. Insufficient folate linked to birth defects. |
| Choline | Essential for fetal development. Helps prevent neural tube defects. |
| Iron | Needed to support ovulation. Deficiency can cause infertility. |
| Zinc | Supports ovulation, hormonal balance, and egg quality. Deficiency linked to infertility. |
| Selenium | Antioxidant that helps protect eggs and embryos. May improve sperm motility. |
As you can see, eggs contain a wealth of vitamins and minerals linked to fertility and reproductive health. The iron, folate, vitamin D, and choline in eggs are particularly valuable for women trying to conceive.
Key benefits of eggs for fertility:
– Provide protein needed for building healthy eggs and embryos
– Supply choline to prevent birth defects
– Packed with iron to support ovulation
– Contain folate, zinc, and vitamin B12 for DNA synthesis
– Source of vitamin D, which may increase IVF success
– Good source of antioxidant selenium
The bottom line is eggs are a fertility superfood, thanks to their stellar nutritional profile. But are boiled eggs just as good for fertility as eggs prepared other ways?
Do boiled eggs have the same fertility benefits?
Boiling is a healthy way to prepare eggs without adding unnecessary fat or calories. But some people worry that boiling may destroy the nutrients in eggs that are so beneficial for fertility.
Luckily, research indicates that boiling eggs does not deplete most of the key nutrients important for conception and pregnancy:
Vitamin retention during boiling:
– Folate: Stable with boiling
– Vitamin A: Little loss with boiling
– Vitamin B12: Stable with boiling
– Vitamin D: Stable with boiling
– Vitamin E: Some loss with boiling
Mineral retention during boiling:
– Iron: Stable with boiling
– Zinc: Stable with boiling
– Selenium: Stable with boiling
The main nutrients degraded by boiling eggs are vitamin C and the antioxidant carotenoids like lutein and zeaxanthin. However, eggs don’t contain high amounts of these nutrients in the first place.
Overall, research shows boiling preserves the majority of the key fertility boosting nutrients in eggs.
Other benefits of boiled eggs
In addition to retaining most fertility nutrients, boiled eggs have several other advantages:
Higher protein availability
Cooking denatures egg proteins, making the protein more digestible and usable for the body. One study found protein availability increased from 50% in raw eggs to 91% in boiled eggs.
Lower risk of salmonella
Raw or undercooked eggs carry a small risk of salmonella infection. Boiling eggs kills any bacteria present.
Longer shelf life
Boiled eggs can be kept refrigerated for about 1 week, while raw eggs only last 1-2 days. The longer shelf life makes boiled eggs a convenient fertility-boosting snack.
Portability
Boiled eggs are easy to transport and make a great on-the-go snack. You can enjoy their fertility and pregnancy benefits wherever you are.
Versatility
Boiled eggs can be enjoyed on their own, in salads, sandwiches, wraps, veggie bowls and more. Their convenience and versatility makes it easy to incorporate them into your diet.
How many boiled eggs should you eat per day?
Current nutrition guidelines recommend limiting cholesterol intake to 300 mg per day.
Here’s the cholesterol content of eggs:
| Egg size | Cholesterol (mg) |
|---|---|
| Small | 186 |
| Medium | 211 |
| Large | 238 |
| Jumbo | 267 |
Based on the cholesterol content above, here’s how many eggs you can eat per day:
– 2 large boiled eggs
– 2-3 medium boiled eggs
– 3 small boiled eggs
Of course, consuming eggs in moderation is still considered safe for most people. But if you have heart disease or diabetes, you may need to further limit egg intake to 1 per day.
Should I choose egg whites or whole eggs?
The egg yolk does contain the majority of nutrients, including key fertility factors like choline, folate, and iron. However, the yolk also provides all the egg’s fat and cholesterol.
Here’s a comparison of the nutrition in egg whites vs. yolks:
| Nutrient | Egg white | Egg yolk |
|---|---|---|
| Calories | 17 | 55 |
| Fat | 0 g | 5 g |
| Cholesterol | 0 mg | 184 mg |
| Protein | 3.6 g | 2.7 g |
| Selenium | 9.5 mcg | 21.6 mcg |
| Choline | 0.2 mg | 147 mg |
| Folate | 1 mcg | 22 mcg |
As you can see, the yolk contains the majority of nutrients but also provides all the cholesterol. The whites provide high-quality protein with little fat or cholesterol.
Here are some options depending on your goals:
– Limiting cholesterol: Egg whites
– Maximizing nutrition: Whole eggs
– Balance of both: Mix of whole eggs and whites
Including some whole eggs in your diet can provide beneficial fertility nutrients without going overboard on cholesterol. But speak to your doctor if you have specific cholesterol or health concerns.
Tips for eating boiled eggs to boost fertility
Here are some simple tips to start enjoying boiled eggs as part of a fertility boosting diet:
Make them ahead
Boil a dozen eggs at the start of each week. Store boiled eggs in the refrigerator for an easy protein source all week long.

Conclusion
Boiled eggs can absolutely be part of a fertility-boosting diet. They retain most of the key vitamins and minerals linked to reproductive health that make eggs such a powerful food for fertility. Including a few boiled eggs per week gives you an easy and nutritious way to help support conception and a healthy pregnancy. Just be mindful of your overall egg and cholesterol intake. Focus on whole foods like eggs while limiting processed foods and added sugars. Your diet is just one factor when trying to conceive – but optimizing your nutrition with fertility superfoods like eggs can help set the stage for success.
