AKUSHERSTVO I GINEKOLOGIIA. 1979; 2:3-5.The problem of human reproduction, especially of birth rate regulation has received much attention in the last decade. The main goal of the enlarged program of research undertaken by WHO in 1977 is to find modern, safe, convenient, and effective methods of contraception which are helpful for family planning. The basic topics under study are oral contraceptives, hormonal medications with prolonged effectiveness, intrauterine contraception, intravaginal and intercervical contraception, contraceptives from plants, biochemical methods of determining ovulation and others. Promising methods under study are the immunological approach based on the search for vaccines with the ability to inhibit sperm locomotion, development of zygote or implantation of the ovum and new methods for male fertility contraception (e.g., intranasal introduction of steroids). Definite attention is paid to methods of surgical sterilization of men and women. Problems of the postabortion period and treatment of infertility are also under intensive investigation in many countries participating in the WHO enlarged program on human reproduction.
