People who are ‘allergic’ to humans

Ro, Christine.

The mystery of how this occurs is still being solved, but some people are allergic to others.

According to Maura, condoms saved her life.

Maura, a 43-year-old Ohio, US resident, claims the issue began in her twenties and gradually caught up with her. She recalls, “After [unprotected] sex, I noticed that my genitals burned.”.

To preserve her privacy, Maura’s name has been changed, but she didn’t feel comfortable telling her partner about it. She would therefore wait for him to go before giving herself a good wash. She experimented with switching from soap to lubricant as her personal care item. But the condition only got worse, spreading to include redness and swelling. Additionally, it only occurred after she came into contact with semen.

She eventually ended her relationship with him and began dating a man who was committed to using condoms. “Until we were lying in bed after sex one night and my tongue suddenly started to swell,” Maura explains, “it wasn’t an issue.”. “When my partner realized what was going on, he yelled, ‘You’re asphyxiating!’ and snatched up my inhaler. He managed to jam it into the corner of my mouth and began firing it. Fortunately, my breathing was sufficient to allow the medication to enter my lungs. “..”.

According to Maura, who also suffers from asthma and several other allergies, the condom may have leaked. Now, she and her long-term partner use condoms even more sparingly. She claims that she was unaware that semen allergies were possible until it happened to her.

Some people experience severe immune reactions to other people’s bodies, though they are very uncommon. These frequently misdiagnosed illnesses can impact not only one’s health but also one’s employment, interpersonal relationships, and general way of life. However, the specifics of these reactions and their causes are still mostly unknown. These odd reactions are giving scientists clues about the chemistry of our bodies and the peculiarities of the human immune system. Are they actual allergies or something else?

straight from the skin.

Sensitivity to the body of another person is frequently associated with the appearance of external products in that body. For example, synthetic fragrances found in deodorants and aftershaves can be carried by the skin. Contact allergies have been connected to more than 150 fragrances.

Sometimes the trigger is unclear. A woman in the United States experienced crippling allergic reactions to her husband’s scent after developing a severe case of mast cell activation syndrome, a condition in which cells that fight infection begin to malfunction. Although the connection isn’t established, some patients with mast cell disorders believe they are sensitive to chemicals released by other people’s skin or natural body odors, according to Sabine Altrichter, a physician at Kepler University Hospital in Austria.

Numerous substances that contribute to body odor are released by the skin. Some of the chemicals that can be found in these skin gases include toluene, which is found in crude oil and is used to make paints and plastics. People can inadvertently or intentionally absorb toluene, such as when they inhale glue to get high, or through exposure at work. Among the many other chemicals found in tobacco smoke is toluene.

Individuals with the enigmatic illness known as People Allergic To Me (PATM) may be able to provide some insight into how people react to other people. Others commonly experience allergy-like symptoms, like coughing and choking, in their presence, which is a strange and isolating phenomenon known as PATM.

Yoshika Sekine, a chemistry professor at Tokai University in Japan, and his associates looked into the skin gases released by people who were complaining of PATM symptoms in 2023. Toluene was particularly likely to be present among the 75 skin gases the team examined. On average, those in the PATM group released 39 times as much of this chemical as those in the non-PATM group.

When you breathe, you inhale toluene through the air. As a toxic substance, it is usually broken down by the liver and eliminated in the urine, according to Sekine. He adds, “Toluene builds up in the bloodstream and is subsequently released through the skin because PATM patients have a reduced capacity to break it down.”.

According to Sekine, there are currently no diagnostic standards for PATM, and the concept itself is still not widely accepted.

Sweat allergies, on the other hand, typically involve sensitivity to one’s own sweat rather than that of others. Regarding hair, the few instances in which allergies to human hair have been documented have been brought on by allergens in external substances rather than the hair itself. For instance, formaldehyde derivatives found in keratin hair treatments or cat proteins that enter cat owners’ hair are examples of such substances.

from biological fluids.

However, certain allergens present in bodily fluids can also cause allergic reactions. In one instance in the UK, a woman who was allergic to Brazil nuts experienced hives and dyspnea following intercourse with a man who had consumed mixed nuts just hours prior, despite the fact that he had cleansed his skin, teeth, and nails beforehand. Additionally, nuts have caused severe allergy sufferers to experience allergic reactions when kissing.

Saliva has been known to cause allergic reactions after eating fruits, vegetables, seafood, and milk, although nuts are the most frequently reported allergen that causes problems when kissing. After vaginal and possibly oral sex with individuals who had taken antibiotics, women with antibiotic allergies have experienced adverse reactions.

However, proteins found in specific body fluids themselves can also cause a reaction in addition to these external allergens. Semen is the one that some clinicians are familiar with, but there are still significant knowledge gaps.

The symptoms of a semen allergy, also known as seminal plasma hypersensitivity, can range from an elevated, itchy skin rash (hives) to the potentially fatal allergic reaction anaphylaxis. A 2024 paper states that, while there have been fewer than 100 recorded cases overall, it has primarily been observed in individuals in their 20s and 30s. Prostate-specific antigen, which can elicit an immune response, is the allergen most commonly associated with this sensitivity in seminal plasma. A protein in this fluid, which makes up the majority of semen aside from sperm, is the target of the allergy rather than the sperm itself.

The exact nature of seminal plasma hypersensitivity is unclear, according to Jonathan Bernstein, a clinical medicine professor at the University of Cincinnati’s College of Medicine in the United States who specializes in allergy and immunology. According to Bernstein, there aren’t enough people with seminal plasma hypersensitivity or suitable animal models for the condition to support extensive research.

Semen allergy symptoms can be systemic or localized. It is typically reported that the vagina is affected when the symptoms are localized and restricted to the vicinity of the point of contact. However, in one case report from Spain, a woman who had never had an allergic reaction after vaginal sex passed out and started to exhibit other signs of anaphylaxis after anal sex. A diagnosis of seminal fluid hypersensitivity was made for her. When her skin came into contact with ejaculate in a non-sexual setting, a woman in the US also developed rash and swelling.

Local symptoms may include burning and excruciating pain right after sexual activity. Bernstein states, “It’s [reportedly] like acid,”. According to one of his patients, it feels “like a thousand needles being stuck into your vagina.”. “.

The unknowns surrounding sperm.

Sperm remain mostly a mystery even after their discovery centuries ago. Learn more about these mysterious cells’ remarkable lives from the BBC.

Bernstein points out that a person may be sensitive to the semen of one or more partners. A fresh sample of seminal fluid from a sexual partner is usually used for a skin prick test to make the diagnosis. In his practice, Bernstein usually observes women in monogamous partnerships with men, frequently during periods of infertility. Due to the lack of authorities on semen allergies, some people travel great distances to consult with him. Because doctors are unsure of how to treat them, many patients are dismissed or put on harsh steroid treatments, according to Bernstein.

But according to Bernstein, almost anyone with a semen allergy can benefit from his approach.

There is a significant lack of information regarding semen allergies in men who have sex with other men. Although it’s unclear why, Bernstein claims he has never witnessed a case of this. Although this doesn’t account for the instance where it happened following anal intercourse between a man and a woman, he pondered whether the symptoms might be connected to specific vaginal conditions.

options for treatment.

In order to desensitise the patient, Bernstein previously experimented with injecting a partner’s semen under or inside the skin. The treatment for post-orgasmic illness syndrome, a rare and frequently incapacitating condition in which men are sensitive to their own ejaculate, is comparable to this. However, preparing the samples required a lot of laboratory work, which meant that “patients were having to pay for that,” according to Bernstein.

In a two-hour one-time procedure, Bernstein and his colleagues discovered that localizing the treatment was reportedly just as safe and effective. The sperm and seminal fluid were first separated. Depending on the severity of the patient’s reactions, they then diluted the seminal fluid to one part in a million or one in ten million. The fluid was then inserted into the patient’s vagina at 15-minute intervals. In order to increase the patient’s tolerance, they used the fluid at progressively higher concentrations. They kept an eye on the patient the entire time. With at least that partner, Bernstein claims that “they don’t tend to have many systemic reactions and they are able to tolerate unprotected intercourse thereafter.”.

Very little research has been published on potential allergies to cervicovaginal fluid, a substance secreted by the vaginal and cervix cells that lubricates the area and offers some defense against infections. Marek Jankowski, though, thinks he has seen at least one person with this illness. Jankowski, an assistant professor of venereology and dermatology at Nicolaus Copernicus University in Poland, claims that he once provided treatment to a patient who had visited numerous other medical professionals. The patient stated that his genitalia would get red and itchy around half an hour after vaginal sex. After cunnilingus, his face would itch as well. The patient believed that this was an allergy, but the doctors rejected or mocked this notion, according to Jankowski.

But Jankowski remained open-minded, researching other possible allergies to cervicovaginal fluid secreted by women during intercourse. He states that “the patient ultimately responded well to antihistamines.”. Jankowski and his associates conducted a study as a result of the case, which was published in 2017. Both dermatologists and those who might be afflicted by this condition were polled by the researchers. Although many doctors were skeptical that the condition existed, one-fifth of the dermatologists who responded said they had seen such cases.

Both the victims and their partners may experience complicated emotional effects.

After contact, patients reported hives, redness, itching, burning, and swelling, according to this study. Jankowski and his colleagues estimated that cervicovaginal fluid allergy was as common as semen allergy, which is believed to affect at least tens of thousands of people in the United States alone, based on their reports. Nevertheless, Jankowski notes that “the current level of evidence for cervicovaginal fluid allergy phenomenon is only circumstantial and further research in this field would be necessary.”.

Since condoms wouldn’t protect the groin and scrotum, they are unlikely to alleviate the symptoms of any allergy to cervicovaginal fluid, which is one way that allergies to semen differ from those to the latter. Jankowski and his colleagues’ survey results, however, suggested that both antihistamines and repeated exposure helped the participants with their cervicovaginal fluid allergy. The flame of passion was apparently stronger than the discomfort, and repeated [exposure] to the allergen led to desensitization, according to Jankowski, who notes that “the majority of cases identified were young adults early in the sexual relationship.”. Seminal plasma hypersensitivity is not known to resolve on its own; this is different.

The repercussions can be severe for those who are allergic to a certain feature of their spouse. Maura thinks that her sensitivity to semen contributed to her and her partner’s decision to forgo having children because she anticipates that finding a solution that would have allowed her to avoid being around semen would have been costly.

The emotional effects on victims and their partners can be complicated. Maura claims that although her partner is content to use condoms and their relationship is safe, “he did tell me that he was offended by the idea that I was allergic to his semen,” she adds. He blames the universe for that, not me. “..”
