Bacteria milked up: There are bacteria from the rectum outside and around the urethral opening, which is only 1-2 millimeters away fro the vaginal opening. They get pushed up the urethra by the pumping action of penis in the vagina, which lies directly under the urethra. Thus bacteria are "massaged", pushed or milked up into the bladder where they multiply and cause a uti. Hence advice to empty bladder after sex.

Flush them out!: During sex, there are several exchanges. Skin cells, fluids and bacteria are the most common exchanges. Women are most affected during these exchanges due to our short urethras. The debris can get to the opening of the urethra and travel a short distance to the bladder and wreak havoc! urinate as soon as you can after sex to "flush out" the possible debris. Drink plenty of water to help you out.

Honeymoon cystitis: Intercourse causes some of a woman's own bacteria to be pushed into her urethra were the can enter the bladder and multiply and cause cystitis. Some women have particularly "sticky" bladder epithelial cells which actually attract bacteria and allow them to adhere rather then be washed with urination.

Possibly: Sexual activity may create swelling of the urethra (tube from bladder to outside) or to the urethral outlet. This is a form of physiologic obstruction which can predispose to secondary uti. Women with this problem can be placed on prophylactic antibiotics which will help to minimize this.

Cranberry: Studies suggest that taking cranberry tablets or juice can reduce the risk of utis. Drinking lots of fluid and emptying your bladder before and after intercourse may help, too. If you have 3 utis within a year, your doctor may recommend using a very low dose of an antibiotic when you have sex.

Honeymoon cystitis: This is a phenomenon observed in newly weds, who have sex for the first time and lots of it. The female urine pipe draining the urine from the bladder is comparably short, and accommodates bacteria to be pushed into the bladder during intercourse. If drinking plenty of fluids does not help, a short course (1- 3 days) of antibiotics may remedy the situation.
