Can You Be Allergic To Semen Or Sperm

Although it is relatively rare, someone can develop an allergic reaction to semen. This may happen because of semen allergy, which is termed seminal plasma hypersensitivity. In this case, the body may react to proteins found in semen.    

After contact with semen, the person may develop symptoms such as itching, swelling, burning, redness, or hives in the genital area.  

In some rare cases, the symptoms can be systemic, affecting the entire body instead of just genital organs. Severe symptoms of semen allergy include breathing difficulties or even anaphylaxis.

Composition of semen

Semen or seminal fluid is ejaculated from the male reproductive system. Its volume and composition may slightly vary from one individual to another. It is a mixture of fluids secreted by various glands of the male reproductive system. 

Here is a general overview of the elemental composition of human semen:


Sperm cells, or Spermatozoa, are the male reproductive cells responsible for fertilizing the female egg (ovum) during sexual reproduction. Semen contains these cells in a small percentage.  

Sperm count indicates the number of sperm cells in one milliliter (mL) of semen. It forms a small percentage of the total volume of semen.       

Seminal fluid

The fluids secreted by several glands of the male reproductive system combine and form seminal fluid. It provides nourishment to the sperm cells. The fluid contains various nutrients including citric acid, zinc, calcium, sodium, potassium, proteins, lipids, and so on.   

Prostatic fluid  

This fluid is secreted by the prostate gland. It makes up a significant portion of semen volume. Prostatic fluid contains components including citric acid, acid phosphatase, enzymes, and others.  

Overall, semen is a carrier of sperm cells. It provides nourishment and protection to sperm by facilitating a suitable environment for survival. It serves as a medium for the transportation of sperm to the female reproductive tract.

The composition of semen may differ in every individual. It depends on the parameters including age, general health, diet, and individual differences.   

Bulbourethral (Cowper’s) gland fluid

This fluid is secreted by the Cowper’s glands. It gets released before ejaculation and helps lubricate the urethra. It neutralizes any residual acidity from urine.    

Can you be allergic to semen?     

Yes, it is possible. Some people might be allergic to semen. When their skin comes into contact with semen, allergic reactions might be triggered. Some may develop mild symptoms.  

There is also a possibility of developing severe allergic reactions such as breathing problems or anaphylaxis, wherein the body becomes hypersensitive.

Several other possible complications of semen allergy are wheezing, nausea, vomiting, breathing difficulties, swelling in the tongue and throat, dizziness, fainting, and weak pulse. See your doctor if you develop such symptoms after exposure to semen.

Is semen allergy common?

Semen allergy is not quite common though. The prevalence of semen allergy cannot be exactly known, as most of the cases go unreported. If the exact stat is known, then the number would be greater than the reported cases. 

People may feel embarrassed to disclose their allergy problems. Some people may even not realize the true cause of such allergic reactions. Thus, it may go unnoticed.      

Diagnosis of semen allergy     

A semen allergy can happen in both males and females. If you are experiencing several symptoms of semen allergies, when you come into contact with semen, then you must see a healthcare provider.                  

They will conduct diagnostic evaluation by performing thorough analysis by checking medical history, physical examination, and sometimes allergy testing.      

Treatment techniques involve the avoidance of semen exposure. By employing several techniques such as barrier methods during sexual activity, one can prevent allergic reactions to semen.

Also, desensitization therapy done through medical intervention and supervision can be beneficial for the avoidance of allergy symptoms. 


In case you are experiencing symptoms like itching, swelling, burning sensation, redness, or hives in the genital area, after coming into contact with semen, then you should necessarily consult a healthcare provider.

They will examine your symptoms and suggest an appropriate treatment. The treatment techniques involve desensitizing, thereby making you less sensitive to your partner’s semen. This will make it easy to get pregnant naturally without any allergic reactions.  

To conceive, the provider may suggest a technique, called intrauterine insemination (IUI), which involves washing of sperms free of semen proteins to prevent an unwanted reaction.   

For individuals with a severe sensitivity to semen, the way of conception is assisted reproductive technology. Your healthcare provider will recommend a suitable technique for your condition.    

These techniques include, In vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), which may lead to successful conception and pregnancy.
