Other factors resulting in a high incidence of abortion have included shortages of high-quality modern contraceptives and reliance upon less dependable traditional methods; a lack of knowledge among couples of contraception and of the detrimental health consequences of frequent abortions; and the absence of adequate training for physicians, nurses, teachers and other specialists. In 1989, the availability of condoms in the entire former USSR amounted to only 11 per cent of demand; intrauterine devices (IUDs), 30 per cent; and pills, 2 per cent. Data from the 1990 all-union sample survey of contraceptive use indicate that, in Azerbaijan, 6.5 per cent of all women aged 15–49 years regularly used contraception, 10.1 per cent sometimes used contraception, 41.9 per cent did not use any contraceptive method and 35.3 per cent knew nothing about contraception.[1]
