The Family Planning Association has recently introduced a nationwide poster campaign warning young people, particularly women, about the dangers of chlamydiainfection, which can cause infertility.
It may be provoked by infection with Chlamydia trachomatis, a sexually transmitted denizen of the genital tract, and Ureaplasma urealyticum and Mycoplasma fermentans, two other inhabitants of the genitals.
Eight out of ten sportsmen studied by Oyudo had an infection call non-specific urethritis, and two tested positive for chlamydia, another sexually-transmitted disease.
