Why Do I Have Blood In My Semen?


Encountering unexpected changes in your body can be concerning, and one such occurrence that might raise alarm bells is discovering blood in your semen. This phenomenon, known medically as “hematospermia,” can understandably lead to a range of questions and worries. In this comprehensive guide, we’ll delve into the causes, potential concerns, and steps to take if you find yourself facing this situation.


What Causes Blood in Semen?

The appearance of blood in semen can have various underlying causes. While it’s natural to feel concerned, it’s important to remember that most cases of hematospermia are not linked to serious medical conditions. Some common causes include:


Engaging in vigorous sexual activity or experiencing a minor injury to the genital area can lead to the presence of blood in semen.


Certain infections, such as sexually transmitted infections (STIs) or urinary tract infections (UTIs), can trigger inflammation and result in blood in semen.

Prostate Issues

Conditions like prostatitis (inflammation of the prostate) or benign prostatic hyperplasia (enlargement of the prostate) can lead to hematospermia.

Medical Procedures

Some medical procedures, like prostate biopsies or vasectomies, may cause temporary blood in semen.


Is Blood in Semen a Cause for Concern?

Discovering blood in your semen can be unsettling, but it’s essential to differentiate between when it’s a minor concern and when it might warrant more attention. In most cases, isolated instances of blood in semen are not indicative of a serious issue. However, if you experience any of the following, it’s wise to seek medical advice:

Frequent Recurrence

If you notice blood in your semen consistently over a prolonged period, it’s advisable to consult a healthcare professional.

Additional Symptoms

The presence of other symptoms, such as pain during ejaculation, discomfort in the pelvic region, or pain during urination, could indicate an underlying problem.


When to Consult a Doctor

While isolated incidents of blood in semen are often harmless, there are certain situations where consulting a doctor is crucial:

Blood in Semen but Not Urine

If blood is only present in your semen and not in your urine, it’s likely a localized issue. However, discussing this with a doctor can provide clarity and peace of mind.

Blood in Semen After Vasectomy

While this can be normal in the immediate aftermath of a vasectomy, persistent or recurrent blood in semen should be discussed with a healthcare provider.

Blood in Semen After Sex or Prostate Biopsy

These occurrences are relatively common and usually resolve on their own. However, if they persist or are accompanied by concerning symptoms, a doctor’s opinion is recommended.

Brown Blood in Semen

The presence of brownish or discolored blood may indicate older blood and might not be a cause for major concern. Still, it’s wise to consult a medical professional to rule out any potential issues.


What to Do if You Find Blood in Your Semen

If you find blood in your semen, consider taking the following steps:

Monitor the Situation – If it’s a one-time occurrence and you’re not experiencing any other symptoms, monitor the situation for a few weeks.

Stay Hydrated – Drinking plenty of water can help dilute your urine and semen, potentially reducing the appearance of blood.

Consult a Doctor – If the issue persists, worsens, or is accompanied by other symptoms, schedule an appointment with a healthcare professional.


Experiencing blood in your semen might be a cause for concern, but armed with knowledge, you can approach the situation with confidence. While many cases of hematospermia are harmless and temporary, it’s always a good idea to consult a medical expert if you’re unsure or experiencing additional symptoms. Remember, your health and well-being are worth prioritizing, and seeking professional guidance can provide the clarity you need.

Wearing tight pants and underwear

Studies show that men who wear looser underwear have higher sperm concentration and total sperm count compared to men who wear tighter underwear. So, lose the tight clothes and wear something loose to give your testicles some air.

CONCLUSION: learn more about how heat can affect sperm quality here.


Besides higher mortality rate and various diseases, stress is associated with low sperm quality. Stress is known to be associated with lower testosterone levels and oxidative stress with both playing an essential role in producing and maintaining healthy sperm cells.

CONCLUSION: If you feel stressed, we recommend you get some help so you can have a balanced mental health. For a stress management guide, download the ExSeed app for free and start your personalized action plan today.

Physical activity

Scientific studies show that men who are physically active have better semen parameters than men who are inactive. Fertility specialists also state that regular physical activity has beneficial impact on sperm fertility parameters and such a lifestyle can enhance the fertility status of men.

Prioritizing exercise can help improve your overall health and result in healthy, fast swimming sperm cells that have good chances of fertilizing an egg.

CONCLUSION: Try incorporating exercise in your weekly schedule to you ensure exercising at least twice weekly. We recommend a combination of cardio training and strength exercise. Read more about exercise and male fertility on our blog.


Fast Food
Processed foods damage the health of sperm-producing cells and cause oxidative stress, which lead to poorer sperm quality. Heavy consumption of junk food (every week) can increase the likelihood of infertility since men who consume vast amounts of unhealthy food are at risk of having poor sperm quality. Besides harming your fertility, junk food enlarges your waistline, harms your cardiovascular system, kidneys, and more.

Eating more fruit and vegetables can increase your sperm concentration and motility. It’s important that you consume a healthy diet filled with antioxidants and that you eat vegetables every day. Foods such as apricots and red bell peppers are high in vitamin A, which improves male fertility by nurturing healthier sperm. Men who are deficient in this vitamin tend to have slow and sluggish sperm.

Sugary snacks/beverages: several times a week Excessive consumption of high sugar items can lead to oxidative stress, which negatively impacts testosterone levels and sperm motility. Sugary snacks and beverages are also highly associated with obesity and low fertility.
CONCLUSION: To boost sperm quality, stay away from fast food, processed food, and sugary snacks or beverages. You need to implement a healthy prudent diet filled with necessary superfoods needed for good sperm production. Check out our guide to Male Fertility Superfoods.

Direct heat can inhibit optimal sperm production and cause Sperm DNA damage. Sperm cells like environments that are a couple of degrees lower than body temperature. Avoid overheating from warm blankets, seat warmers, heat from your laptop, hot showers, and saunas.

Cigarette smoking

The exposure to tobacco smoke has significant negative effects on semen quality. The damage of cigarettes and nicotine of course depends on how many cigarettes you smoke per day and for how long, but even low usage (up to 10 cigarettes / day) can inhibit healthy sperm production.  

CONCLUSION: Stay as far away from cigarette smoking as possible if you care about your general health and your fertility. Read more here.

Cell phone

When you have your cell phone in your front pocket, your testicles are exposed to electromagnetic radiation, which studies have shown to damage the sperm cells. Put your phone in the back pocket of your pants or in your jacket pocket.


There is a clear association between obesity and reduced sperm quality. At least part of the reason for this is that obese men may have abnormal reproductive hormonal profiles, which can impair sperm production and lead to infertility. 

A BMI higher than 30 can lead to several processes in the body (overheating, increase in oxidative stress in the testes, sperm DNA damage, erectile dysfunction) that can have a negative impact on male fertility. This can result in problems when trying to conceive.  

CONCLUSION: BMI is one of the risk factors that influence semen quality and, for example, sperm motility.  


A beer or glass of wine now and then do not really harm sperm quality. But excess alcohol drinking (more than 20 units per week) can reduce the production of normally formed sperm needed for a successful pregnancy.

CONCLUSION: If you want to stay safe, stay under 14 units of alcohol per week. For more information on how alcohol can affect male fertility, take a look at our blog: “Alcohol and Sperm Quality”.


Studies show that women younger than 35 and men younger than 40 have a better chance of getting pregnant. Men can produce sperm cells almost through their entire life, but the sperm cell DNA is more fragile and prone to damage after the age of 40.

As men age, their testes tend to get smaller and softer resulting in a decline in sperm quality and production. These changes are partly because of an age-related decrease in testosterone level, which plays a very important role in sperm

production. Higher male age (>40 years) is not only associated with a decline in sperm production but also with increased sperm DNA fragmentation and worsened morphology (shape) and motility (movement). These negative effects make the sperm cells less qualified for egg fertilization.

CONCLUSION: with an age under 40, you shouldn’t have to worry much about age as a factor in itself. However, studies have shown a slow decline after the age of 30-35 years

and if you are above 40 years of age, your sperm quality can be affected due to increased sperm DNA damage resulting in a decrease of sperm motility and concentration. Remember that you cannot evaluate the quality of a sperm sample by just looking at it – this requires a sperm analysis.
