Contraception. 1973 Jul; 8(1):67-73.The World Health Organization (WHO) Program of Research in Human Reproduction that began in 1972 deals with the development of a variety of safe, acceptable, and effective methods for the regulation of human fertility. Research has concentrated on areas where international collaboration would be most likely to accelerate the development of new methods. The program is clinically oriented and emphasizes meeting the objectives in the shortest possible time. Collaborative task force research was started in the following fields: 1) methods to interfere with the transport and/or survival of the ovum; 2) methods to prevent the implantation of the fertilized ovum in the uterus; 3) contraceptive methods for men that affect the fertilizing capacity of sperm by interfering with their maturation and survival without affecting sexual competence; and 4) methods to regulate sperm migration and survival in the human female.
In: World Health Organization (WHO). World Health Organization expanded programme of research, development, and research training in human reproduction: fourth annual report. Geneva, Switzerland, WHO, November 1975. 33-36. (HRP/75.3)Methods of tubal occlusion being studied for use in developing countries are summarized. A comparative clinic trial will be undertaken in the CCCR network to assess safety of tubal occlusion by surgery when performed postpartum through a vertical miniincision and when performed as an interval procedure by minilaparotomy, laparoscopy, colpotomy, or culdoscopy. 8 chemical tubal occluding agents are being studied at the Central Drug Research Institute in India. Postcoital birth control methods are being investigated including: methods to alter the rate of ovum transport, methods of changihg oviduct motility (including the effect of steroids, catecholamine stimulating and blocking agents, prostaglandins, ergot derivatives, and oxytocics), and methods affecting ovum survival. A WHO Symposium on "Ovum Transport and Fertility Regulation" was held in June 1975 in San Antonio, Texas, to present the work of these various scientists.
In: Hankinson, R.K.B., Kleinman, R.L., and Ekstein, P., eds. Proceedings of the Eighth International Planned Parenthood, Santiago, Chile, April 9-15, 1967. London, International Planned Parenthood Federation, 1967. 501-506.Control of fertility in the male, ovum transport and fertilization, and the endocrinology and pharmacology of implantation are cited as areas of future study in contraception. In summarizing the proceedings of the Basic Science Sessions of the 8th International Conference of the International Planned Parenthood Federation, it is stated that 1) little has been developed in the immunological control of fertility, 2) the mechanism of IUD action is undetermined, and 3) 19-nor steroids do not appear to act directly on the ovary.
