Who is most at risk

Although the specific cause that leads to the emergence of sperm allergy is not known, it is possible that the risk is greater in people who already have some type of allergies, such as allergic rhinitis or asthma, for example.

  • Being in menopause;
  • Use the IUD;
  • Having removed the uterus.

In addition, the semen of men who have removed part or all of the prostate also appears to cause the greatest number of allergic reactions.

How the treatment is done

The first form of treatment recommended to relieve the symptoms of semen allergy is to use a condom during intercourse, in order to try to avoid coming into direct contact with the semen, thus preventing the development of the allergy. Here’s how to put the condom on correctly.

However, this form of treatment may not work for those who are trying to conceive or for men who are allergic to their own semen, so the doctor may prescribe the use of antiallergens. In the most severe cases, where the allergy can cause difficulty in breathing, the doctor may even prescribe an injection of epinephrine, to be used in emergency cases.

Another form of treatment is to decrease sensitivity to semen over time. For this, the doctor takes a sample of the partner’s semen and dilutes it. Then, small samples are placed inside the woman’s vagina every 20 minutes until the sperm concentration is reached. In these cases, it is expected that the immune system will stop responding so exaggeratedly. During this treatment, the doctor may also advise you to have intercourse every 48 hours.
