Summary Introduction
To write:
How frequent douching can be a predisposing factor to bacterial vaginosis, vulvovaginal candidiasis and trichomoniasis
Given:
Frequent douching is a predisposing factor to bacterial vaginosis, vulvovaginal candidiasis and trichomoniasis
Introduction:
Cleaning the intravaginal area with liquid is termed as douching to prevent infection. However, frequent douching may disturb the normal healthy flora of the vagina which leads to pelvic associated diseases.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
