Is there a connection between Thick blood and fertility?

Yes, Thick blood and Fertility are related to each other. Thick blood, also known as hypercoagulability, refers to blood that has a higher tendency to form clots.

Starting a family is a beautiful dream for many people, but it doesn’t always happen easily. Sometimes, something called “thick” or “sticky” blood can make it more difficult to have a baby. In this article, we’ll discuss what thick blood means, how it can create challenges when you’re trying to get pregnant, why it occurs, what can be done to help, and the valuable advice you can receive from experts.

Understanding Thick Blood and How It Affects Having a Baby:

To begin, let’s grasp what having thick blood means:

– Thick Blood (Hypercoagulability): This is when your blood tends to make clots more easily. While clots are good for stopping bleeding when you’re hurt, having blood that clots too much can create issues in different situations.

How to diagnose with thick blood?

Finding out if you have thick blood isn’t too complicated, but it involves several steps:

1. Talk About Your Health:

  • Your doctor will chat with you about your health and any family history of blood clot problems. They’ll also ask about any past surgeries or illnesses that might be connected to thick blood.

2. Physical Check:

  • The doctor might give you a physical checkup. They’ll look for signs like swelling, redness, warmth, or tenderness in your arms or legs, which can hint at blood clot issues.

3. Blood Tests:

These tests check different things in your blood:

– Complete Blood Count (CBC): This counts your blood cells. If you have too many red blood cells or platelets, it could mean your blood is getting thicker.

– Coagulation Profile: These tests check how well your blood can clot. If they’re not right, it might show that your blood is too prone to clotting.

– D-dimer Test: This measures a substance that appears when a blood clot breaks down. High levels could mean there’s a clot.

– Genetic Tests: If others in your family have had clot problems, you might have genetic tests to see if there’s a specific gene that’s making your blood thicker.

4. Imaging Tests:

These tests use pictures to look at your blood vessels:

– Ultrasound: This helps doctors see how blood is flowing in your veins and if there are any clots, especially in your legs.

– CT Scan or MRI: These more detailed scans can check for clots in your chest or belly.

5. Special Tests:

  • If the initial tests find something unusual, your doctor might suggest more specific tests to figure out the exact problem causing your thick blood.

6. Seeing a Specialist:

  • Depending on the results, your doctor might send you to a specialist who knows a lot about blood problems (they’re called hematologists) for further checks and advice.

How Thick Blood Can Affect Fertility?

  • To understand how thick blood impacts fertility, we need to look at the role blood plays in the reproductive process. When you’re trying to have a baby, a few key things need to happen:
  • Healthy Blood Flow to Reproductive Organs: Your reproductive organs, like the ovaries and the uterus (where a baby grows), need a good supply of blood. Blood carries oxygen and nutrients that these organs need to work properly.
  • Unobstructed Path for Eggs and Sperm: When you ovulate (release an egg), it needs to travel through your fallopian tubes to meet the sperm. If there are any blockages or problems in these fallopian tubes due to blood clots, it can be hard for the egg and sperm to meet.
  • Successful Implantation: After fertilization (when the egg and sperm meet), the fertilized egg must attach itself to the lining of your uterus for pregnancy to start. Thick blood can make it difficult for this attachment to happen.

Now, let’s see how thick blood can create challenges in these aspects:

Reduced Blood Flow:

Thick blood doesn’t flow as easily as thinner blood. This can mean less oxygen and fewer nutrients reaching your reproductive organs, potentially affecting the development of eggs and sperm. So, Thick blood affects your fertility.

Risk of Clots:

  • Thick blood has a higher tendency to form clots. These clots can block the fallopian tubes or uterine arteries, creating obstacles for the egg and sperm to meet and fertilize.

Difficulty in Implantation:

  • Thick blood can make it harder for the fertilized egg to attach to the uterine lining, which is crucial for the start of a pregnancy.

Understanding What Causes Thick Blood and Its Impact on Fertility

Thick blood, also known as hypercoagulability, occurs when your blood has a higher tendency to form clots. This condition can have significant implications for fertility. Here, we’ll delve deeper into the factors that can make your blood thicker and how they relate to fertility.

Genetic Factors:

  • Sometimes, thick blood can be hereditary, meaning it runs in the family. If you have close relatives with clotting disorders or a history of thick blood, you may be more likely to experience similar issues. Genetic predisposition can play a role in how your blood behaves and can impact your fertility journey.

Hormonal Imbalances:

  • Hormones are key players in your reproductive system, regulating various processes required for fertility. Imbalances in hormone levels, such as those seen in conditions like polycystic ovary syndrome (PCOS) or thyroid disorders, can lead to changes in blood viscosity. These hormonal shifts can affect the quality of eggs and sperm, making it more challenging to achieve conception.

Medical Conditions, like Thrombophilia:

  • Certain medical conditions, such as thrombophilia, are characterized by an increased tendency to form blood clots. These clotting disorders can have a direct impact on fertility by obstructing blood flow to the reproductive organs. In women, this can affect the maturation of eggs, while in men, it may impair sperm production and function.


  • Some medications, particularly those that affect blood clotting or blood thickness, can contribute to thickening of the blood. If you are taking medications as part of your medical treatment, it’s essential to discuss their potential effects on blood viscosity with your healthcare provider. They can provide guidance on balancing the benefits of the medication with potential impacts on fertility.

Lifestyle Factors:

  • Lifestyle choices play a crucial role in blood thickness and, consequently, fertility. Smoking and being overweight are two lifestyle factors that can contribute to thicker blood. Smoking can increase the risk of clot formation, while excess weight can lead to hormonal imbalances and affect the overall health of reproductive organs. Making positive lifestyle changes can improve blood flow and fertility outcomes.

What Can Be Done If Thick Blood Affects Your Chances of Having a Baby:

If you suspect that thick blood is causing problems with getting pregnant, there are ways to deal with it:

  1. Medications That Thin the Blood: Doctors can give you medicines that make your blood less likely to form clots and help it flow better.
  1. Changing How You Live: Making healthier choices, like eating good food, staying active, and drinking enough water, can help your blood work better.

Expert Advice for Couples Facing Thick Blood and Fertility Challenges:

If you’re having trouble getting pregnant because of thick blood, don’t hesitate to talk to experts who can help:

– Fertility Specialists: These doctors specialize in helping people have babies. They can give you personalized care and advice.

In summary, thick blood can impact fertility by reducing blood flow to reproductive organs, increasing the risk of blood clots that can obstruct the path for eggs and sperm, and potentially hindering the process of implantation. If you suspect that thick blood might be affecting your fertility, it’s important to discuss this with a healthcare provider who can assess your condition and recommend appropriate steps to improve your chances of conceiving.
