Dr. Sergey Korolyov, a urology specialist, reported that cystitis can sometimes occur after unprotected sexual intercourse, noting that the causes may include trauma, allergies, or poor hygiene.
The doctor said: "The mucous membranes during intense or prolonged sexual activity can be injured, or there could be poor personal hygiene from either partner, or the use of contraceptives containing irritating components can contribute. However, the main cause is always bacteria, while the aforementioned factors merely predispose. Even the skin of the most hygiene-conscious person contains Escherichia coli bacteria, but usually their numbers are not sufficient to cause inflammation. However, if these bacteria enter a vulnerable environment, such as an allergy to a condom, the risk of inflammation significantly increases."
He pointed out that Escherichia coli bacteria cause acute cystitis in 75-90% of cases, while other types like Staphylococcus, Klebsiella pneumoniae, and Proteus mirabilis contribute less frequently.
He added: "Cystitis usually occurs due to external factors, and is commonly diagnosed in women, as about 60% of women post-puberty experience this condition at least once, while the rate is eight times less frequent in men."
The reason is due to anatomical differences, including the width and shortness of the urinary tract in women, which increases the likelihood of the infection reaching the bladder."
