Is PID common?

In the early 1990s, the self-reported frequency of PID in women was approximately one in nine. PID was more than twice as common in women with a history of sexually transmitted diseases (26 per cent) than among women who had never reported an STD (10 per cent).

Risk factors

Younger age: Sexually experienced teenagers are three times more likely to be diagnosed with PID than their 25- to 29-year-old counterparts. Scientists do not know, however, whether this is due to biological factors that make young women more susceptible to STDs or different sexual behaviors in these two age groups.

Women have the highest risk of PID of the ethnic groups seen in the U.S. This may be related to biological factors, or due to their comparatively high frequency of douching.

Contraceptive Choice: Barrier methods, such as condoms, and oral contraceptives reduce the risk of PID. Despite the problems with the Dalkon Shield in the 1970s, use of modern intrauterine devices (IUD) is not considered to significantly increase the risk of PID, except possibly around the time of insertion.

Douching: Douching greatly increases a woman’s risk of PID.

Concerns about PID

Worldwide, PID is one of the leading causes of ectopic pregnancy and preventable infertility in women. In 1988, a study estimated that the cost of preventable infertility in the US was in the vicinity of $64 billion, and it is probably substantially higher today. This includes the costs of both treating the STDs and PID that cause the infertility, and resolving the infertility in couples who wish to become pregnant. In contrast, the costs of preventing PID-related infertility are probably much lower. Those costs would primarily include those for education about safer sex, douching, and condom use as well as screening and treatment for chlamydia and other STDs. The cost of such preventative measures would probably be only a minuscule fraction of the cost spent on treatment.

The relationship between PID and infertility is relatively well accepted. PID causes

infertility by the scarring process that occurs during the healing of sexually transmitted infections. The extensive scarring can eventually occlude one or both fallopian tubes, and scarring tends to be worse among older women, smokers and women using IUDs. Depending on the extent of scarring it may be impossible for sperm to reach the egg, or, if sperm can get through, the fertilized egg may be unable to get to the uterus.Not surprisingly, the percentage of women who experience infertility due to PID is directly proportional to the number of episodes of PID that they have experienced. Therefore, both treating and preventing PID are important steps in the reduction of infertility.
