Dr. Sergei Korolev, a urologist, stated that cystitis can sometimes occur after unprotected sex, noting that the causes may include trauma, allergies, or poor hygiene.
The doctor said: "The mucous membranes may be exposed to injury during intense or prolonged sexual activity, or there may be poor personal hygiene on the part of either partner, or the use of contraceptives containing irritating ingredients may contribute. But the main cause is always bacteria, while the aforementioned factors are merely predisposing factors. Everyone's skin, even the most hygienic, contains E. coli bacteria , but their numbers are usually insufficient to cause an infection. However, if these bacteria enter a weakened environment, such as an allergy to condoms, the risk of infection increases significantly."
He noted that Escherichia coli bacteria cause acute cystitis in 75-90% of cases, while other types such as Staphylococcus , Klebsiella pneumoniae , and Proteus mirabilis contribute to a lesser extent.
He added: "Cystitis usually occurs as a result of external factors, and is often diagnosed in women, as about 60% of women after puberty suffer from this condition at least once, while the percentage in men is eight times lower.
This is due to anatomical differences, including the width and shortness of the urethra in women, which increases the likelihood of infection reaching the bladder.
