Sperm Allergy: Symptoms, Causes, and Treatment Options

A sperm allergy, also known as seminal plasma hypersensitivity, occurs when a woman develops an allergic reaction to her partner’s semen. While rare, this condition can cause discomfort during or after sex, with symptoms such as vaginal itching, swelling, or a burning sensation. In severe cases, it may even lead to anaphylactic shock, a life-threatening condition.

How to Identify a Sperm Allergy

If you experience itching or discomfort after sex, it’s important to determine whether it’s a sperm allergy or another issue like a fungal infection (thrush). One way to test this is by having sex with a condom. If symptoms persist even with a condom, it’s unlikely that sperm is the cause. However, since some people are allergic to latex, make sure to use a latex-free condom to rule out that possibility.

Causes of Sperm Allergy

The exact cause of sperm allergies remains unclear. However, women who are generally prone to allergies or have had infections like chlamydia may be more susceptible. A sperm allergy can develop at any time, whether it’s your first sexual experience, with a new partner, or suddenly within a long-term relationship. Symptoms typically appear within 10 to 30 minutes of contact with sperm and may spread to other parts of the body.

What to Do If You Suspect a Sperm Allergy

If you think a sperm allergy might be affecting your ability to conceive, it’s essential to speak with your GP. They may recommend treatment to gradually desensitize your body to the allergen, although success is not guaranteed. For those struggling to conceive due to a sperm allergy, assisted conception methods like intrauterine insemination (IUI), in vitro fertilization (IVF), or intracytoplasmic sperm injection (ICSI) are often viable options.

Sperm Allergy in Men

Though extremely rare, men can also experience symptoms of a sperm allergy, typically presenting as flu-like symptoms after ejaculation. If this occurs, it’s important to consult a GP, who may refer you to a specialist for further evaluation and treatment.

In summary, while sperm allergies are rare, they can cause significant discomfort and may impact fertility. Early diagnosis and appropriate treatment can help manage symptoms and improve your chances of conception.
