Dear Editor

The ‘male factor' is crucial to effectiveness of screening and is in danger of being overlooked

There has been much recent correspondence about screening for genital chlamydial infection and the importance of partner notification, which is acknowledged to be optimal in GUM settings1,2. However, we are concerned that two issues have been conspicuously absent from this debate; firstly, the emphasis on women as the target population for screening with no discussion about involving men and, secondly, the absence of discussion about availability of partner notification facilities in general practice (advocated by the advisory committee to the Chief Medical Officer and described by Boag and Kelly3). It seems likely that women have been chosen as the target population for screening because of difficulties in accessing young men in the primary care setting.

The ‘male factor' in chlamydial infection is crucially important in fulfilling any hopes of health gain. Selective screening in women, in health care settings without the resources to effect partner notification, may, paradoxically, create more morbidity than doing nothing at all; the male-to-female transmission rate of the infection is over 70% 4 and each repeated episode of re-infection doubles the risk of tubal infertility5.

Furthermore, there are perhaps some sociological concerns about focusing our public health efforts concerning chlamydial infection so strongly on women, who were traditionally viewed as the reservoir of venereal diseases in the past. Surely, strategies for optimising sexual health in the 1990s should adopt a more enlightened approach?

Successful strategies in Sweden and elsewhere for reduction of morbidity caused by Chlamydia trachomatis have included men in screening programmes. Ignoring the ‘male factor' would seem to be a dangerous course of action and is worthy of more debate.
