Have you ever wondered why your semen may appear watery at times, or is your ejaculate always on the thinner side? In this blog, we will delve into the potential reasons behind this phenomenon and explore various factors that can affect sperm health. Understanding these causes can help you make informed decisions about your reproductive health and overall well-being. 


What is Watery Sperm? 

Semen is a complex mixture of sperm (male reproductive cells) and seminal fluid produced by the male reproductive system. It usually has a thick, whitish appearance. Watery semen, on the other hand, is characterized by a more diluted consistency that may be concerning to some individuals. It’s essential to note that the occasional appearance of watery semen is normal, and semen consistency can vary due to several factors. However, persistent changes in semen consistency might warrant further investigation. 


Why is my Semen Water? 

There are several factors that can contribute to the appearance of watery semen. The possible causes of watery semen include: 

  • Hormonal imbalances: Hormones play a crucial role in sperm production. Fluctuations in hormones, such as testosterone, can affect the quality and consistency of semen. 
  • Lifestyle factors: Your lifestyle choices can impact your reproductive health. Poor diet, smoking, excessive alcohol consumption, drug use, and lack of exercise can all influence sperm quality. 
  • Heat exposure: Prolonged exposure to high temperatures, such as frequent hot baths, saunas, or wearing tight underwear, can raise the scrotal temperature, leading to watery sperm. 
  • Medical conditions: Certain medical conditions like infections, sexually transmitted diseases, varicocele (enlarged veins in the scrotum), and ejaculatory duct obstruction can also contribute to watery sperm. 


Does Watery Sperm Affect Male Fertility? 

If you’ve noticed changes in your semen consistency, you might be wondering about its impact on fertility. Occasional watery sperm might not necessarily indicate fertility issues, for example it’s more common if someone masturbates or engages in sexual activity multiple times each day. However, persistent changes could affect your chances of conception, as watery semen may indicate that someone has a reduced sperm count or low semen quality. These can result from various medical conditions and lifestyle factors. If you and your partner have been trying to conceive without success, it might be worth exploring sperm health as a potential factor. 


When Should I Seek Support? 

If you’re concerned about the consistency of your semen or worried about your fertility, it’s wise to seek support. You’ll want to do a semen analysis to understand the health of your sperm and/or to see if you’ve experienced a decline in healthy sperm since your last test. Tests such as the ExSeed At-Home Sperm Test offer a fast and convenient way to check your fertility all from home, and there’s support available from their in-house medical team. You may also find an in-person appointment with a male reproductive specialist useful, where you can get a sperm evaluation performed and you have additional expert guidance. 


How Can I Improve Watery Sperm for Normal Consistency? 

Fortunately, there are steps you can take to promote better sperm health and possibly improve semen consistency: 

  • Adopt a balanced diet: A diet rich in fruits, vegetables, whole grains, and healthy fats can positively impact sperm quality. 
  • Exercise regularly: Regular physical activity can help maintain hormonal balance and overall well-being. 
  • Manage stress: Chronic stress can affect reproductive hormones, so finding healthy ways to manage stress is crucial. 
  • Avoid harmful substances: Quit smoking, limit alcohol consumption, and steer clear of recreational drugs. 
  • Consider supplements: Some supplements, such as zinc and folic acid, might be beneficial for sperm health, available in the ExSeed Multi and ExSeed Omega fertility supplements. For the best outcomes, these should be taken alongside a healthy and balanced diet. 


Understanding the reasons behind watery sperm is vital for maintaining reproductive health. While occasional changes in semen consistency are normal, persistent issues should prompt a visit to a healthcare professional. By adopting a healthy lifestyle and seeking appropriate medical advice, you can take proactive steps towards improving sperm health and overall well-being. Remember, open communication with your partner and professional support can make the journey to parenthood a smoother one.

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.

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.
