Nocturnal emission
I sometimes experience nocturnal emissions, which started during puberty.
However, in the past year or two, the fluid that is released during these episodes is not semen; it is colorless and less viscous.
What could be the cause of this?

In young men, starting from puberty, the increased secretion of male hormones enhances the testicular ability to produce sperm.
When the frequency of sexual activity at this age is relatively low, excess semen may occasionally be released spontaneously, a phenomenon known as nocturnal emission or wet dreams.
Therefore, nocturnal emission is a normal physiological occurrence.
Due to the reduced control of the brain during sleep and the relaxation of the sphincter muscles, nocturnal emissions are more likely to occur at night.
The components of semen include sperm, seminal vesicle fluid, and prostatic secretions, with seminal vesicle fluid accounting for about 70% of the total volume.
Thus, a less viscous discharge is likely to contain fewer sperm and primarily consist of prostatic secretions, which generally do not indicate any significant issues.
If you still feel troubled by this matter, it is advisable to consult a urologist for a semen analysis.
If the semen quality is normal, you should not have to worry.

More Info
Nocturnal emissions, commonly referred to as "wet dreams," are a normal part of male sexual development, particularly during puberty. They occur when a male experiences ejaculation during sleep, often accompanied by erotic dreams. The changes you are experiencing in the characteristics of your semen, such as it being colorless and less viscous, can be concerning, but they are not necessarily indicative of a serious health issue.
Firstly, it's important to understand that semen composition can vary significantly from one individual to another and can also change over time due to various factors. The primary components of semen include sperm, seminal fluid, and various enzymes and proteins that contribute to its viscosity and color. The appearance of semen can be influenced by hydration levels, diet, frequency of ejaculation, and overall health.
1. Hydration Levels: If you are not drinking enough water, your body may produce less concentrated semen, which can appear more watery or less viscous. Staying well-hydrated is essential for overall health and can affect the quality of your semen.
2. Frequency of Ejaculation: If you have been experiencing more frequent nocturnal emissions or have been ejaculating more often through masturbation or sexual activity, your body may produce semen that is less concentrated. This is because the body may not have enough time to produce a larger volume of seminal fluid, resulting in a thinner consistency.
3. Diet and Lifestyle: Your diet can also play a role in the quality of your semen. A diet lacking in essential nutrients, particularly zinc and vitamins, can affect semen production. Additionally, lifestyle factors such as stress, lack of sleep, and substance use (like alcohol or drugs) can also impact semen quality.
4. Hormonal Changes: As you age, your hormone levels, particularly testosterone, may fluctuate. These hormonal changes can affect semen production and quality. If you are experiencing other symptoms, such as changes in libido or erectile function, it may be worth discussing with a healthcare provider.
5. Health Conditions: While changes in semen characteristics are often benign, certain medical conditions can affect semen quality. Infections, hormonal imbalances, or issues with the reproductive system can lead to changes in semen. If you have concerns about your reproductive health or if you experience additional symptoms (such as pain, swelling, or unusual discharge), it is advisable to consult a healthcare professional for a thorough evaluation.
In summary, while the changes you are experiencing in your nocturnal emissions may be concerning, they are often related to benign factors such as hydration, frequency of ejaculation, diet, and lifestyle. However, if you have ongoing concerns or notice other changes in your sexual health, it is always best to seek advice from a healthcare provider. They can provide personalized guidance and, if necessary, conduct tests to rule out any underlying health issues. Remember, sexual health is an important aspect of overall well-being, and being proactive about it is essential.
