How To Know If You’re Allergic To Semen
When you get redness, swelling, and itchiness down
there, it’s easy to assume it’s a yeast
infection, or perhaps an STD. But experts say it may actually be a sign of
an allergy to semen—yup, semen—causing
your symptoms. While rare, a semen allergy can happen, and they’re not always
easy to detect. Here's what you need to know.
According to the International Society for Sexual Medicine,
a semen allergy (also known as seminal plasma hypersensitivity), is a rare allergic
reaction to proteins found in
a man’s semen that mostly impacts women.
Common symptoms include redness, swelling, pain,
itching, and a burning sensation in the vagina that usually starts about 10 to
30 minutes after you have contact with semen. Symptoms aren’t just restricted
to your vagina, though: They can happen on your skin or in your mouth as well.
Semen allergies can actually be pretty serious:
While the ISSM says that symptoms can be localized, they can also impact your
whole body, causing hives, swelling, trouble breathing, or anaphylaxis, a
life-threatening allergic reaction.
“It’s not very common, but it’s more common than
people may realize,” women’s health expert Jennifer Wider, M.D., tells SELF. It actually
may happen more often than doctors realize because some people may not
recognize or report it, she says.
While severe semen allergies happen, you shouldn’t
freak out and worry that unprotected
sex with your partner will
send you into anaphylactic shock: Maureen Whelihan, M.D., an ob/gyn at the
Center for Sexual Health & Education, tells SELF that those cases are
incredibly rare.
The more common symptoms
are similar to those of a yeast infection or herpes.
So how can you know if you have a semen allergy or one of those infections? For
one thing, Wider points out, the characteristic cottage cheese-like discharge
in yeast infections isn’t there with a semen allergy. Sherry Ross, M.D., an
ob/gyn and women's health expert in Santa Monica, Calif., tells SELF that
figuring out that you have a semen allergy is largely done through the process
of elimination. Doctors will typically test for infections as well as allergies
to latex, spermicide, and lubrication products—all of which are more common
allergies—before looking into a semen allergy, she says.
If a semen allergy is suspected, your ob/gyn may
send you to an allergist who can do a skin test with your partner's semen to
confirm it. You can also do some sleuthing on your own, provided your symptoms
are minor. Timing can help you figure it out, Wider says, since you’ll
typically notice these symptoms soon after your partner ejaculates.
There may be a cure for people with more mild
semen allergies, though: A case study of a semen allergy sufferer published in
the journal Obstetrics and Gynecology found that intravaginal
desensitization (i.e. small exposures of semen in the vagina) essentially cured
a woman of her allergy.
Condom use can also help, Wider says, as can
taking an antihistamine before having unprotected sex. But, if you suffer
extreme semen allergies, your doctor may want you to carry anEpiPen as a precaution.
Naturally, a sperm allergy can make it difficult
to get pregnant. However, the ISSM says women with this allergy can still get
pregnant through artificial insemination or IVF, and the allergy shouldn't impact
the pregnancy.
If you suspect that you have a semen allergy, talk
to your doctor. Whelihan recommends keeping a diary of your symptoms and even
taking photos to show your doctor to help figure out what’s going on. And, if
your symptoms are severe or bother you, use
a condom until you can get to
the bottom of things.
