Tubal infertility: an ounce of (more specific) prevention.

Infertility was a problem experienced by 1.7 million US women in 1984. The national expenditure for infertility exceeds US$1.5 billion annually. There are additional costs in terms of psychological factors such as depression anger and quilt. The main preventable causes of infertility are those resulting from sexually transmitted infections. Bilateral tubal occlusion is the major condition related to past tubal infections and is presumably related to a prior episode of clinical or subclinical upper genital tract infection. Early treatment of symptomatic pelvic inflammatory disease may play a role in reducing the sequelae from infection. In the area of primary prevention the use of both mechancial and chemical contraception appears to provide the greatest degree of protection against tubal infertility. The use of barrier methods such as condoms in conjunction with spermicides has potential to prevent unplanned pregnancy preserve fertility for a future time and protect against transmission of acquired immunodeficiency syndrome and other sexually transmitted infections.
