Mumps, a contagious viral infection primarily affecting the salivary glands, presents with symptoms like fever, headache, muscle aches, and swelling of the parotid glands, which are located on the sides of the face. While mumps is often associated with childhood, it can affect individuals of any age. One of the lesser-known but significant concerns associated with mumps, particularly in post-pubertal males, is its potential link to male infertility.
Mumps Orchitis: The Link to Infertility
Orchitis, the inflammation of the testicles, is a known complication of mumps infection in post-pubertal males. The occurrence of orchitis after mumps infection varies, but estimates suggest that up to 30-40% of post-pubertal males with mumps will develop orchitis. This inflammation can lead to swelling, pain, and discomfort in the affected testicle.

When mumps virus infects the body, it can reach the testicles, leading to orchitis. The inflammation can damage the testicular tissue, affecting sperm production. Orchitis typically occurs within a week or two after the onset of mumps symptoms and can affect one or both testicles.
Impact on Sperm Production:
Orchitis can severely impact sperm production within the testicles. The inflammation can disrupt the delicate process of sperm formation, leading to potential consequences such as reduced sperm count and testicular shrinkage. These effects can significantly impair fertility in affected individuals.
Sperm production, or spermatogenesis, occurs within the seminiferous tubules of the testicles. Inflammation due to orchitis can disrupt this process, leading to the destruction of sperm-producing cells (spermatocytes) and impairing the maturation of sperm. As a result, individuals with orchitis may experience a decrease in sperm count and quality, affecting their ability to conceive naturally.
Mumps and Infertility: Separating Myth from Reality
While concerns about mumps-induced infertility are valid, it’s essential to provide reassurance that severe fertility problems are relatively rare. Studies have shown that while men who develop orchitis after mumps infection may experience a significant reduction in sperm count, complete infertility is uncommon. Only a small percentage of men with orchitis will experience long-term fertility issues.
According to research, approximately 30-87% of men with mumps orchitis experience a decrease in sperm count, with about 30% experiencing a reduction below the threshold of subfertility. However, complete infertility is rare, affecting only a small percentage of individuals.

Prevention is Key:
Prevention remains the cornerstone in mitigating the risks associated with mumps and male infertility. Vaccination against mumps is highly effective in preventing both the infection and its potential complications. The MMR (measles, mumps, and rubella) vaccine is routinely recommended for children and adolescents, typically administered in two doses, the first around 12-15 months of age and the second between 4-6 years old. Additionally, individuals who have not received the vaccine or have incomplete vaccination should consider catching up with the recommended schedule.
Conclusion:
In conclusion, while mumps infection can indeed lead to orchitis and pose risks to male fertility, it’s crucial to understand that severe fertility problems as a result of mumps-induced orchitis are relatively rare. Most men who develop orchitis after mumps infection will not experience long-term infertility. However, anyone with concerns about mumps or male infertility should consult with a healthcare professional for personalized advice and guidance. Prevention through vaccination remains the best strategy to safeguard against the risks associated with mumps infection and its potential impact on male fertility.
