The efficacy of a recently marketed posttesticular male oral contraceptive, Contrasperm, was assessed in a clinical trial involving 32 Malaysian volunteers ages 21-39 years. Contrasperm is claimed to be a pure botanical extract free of toxic chemicals, steroids, and hormones. The drug is believed to cause cells surrounding the sperm in the seminiferous tubules to secrete carbon dioxide, producing a weakly acidic environment that greatly increases the sperms' metabolism and reduces the pH of semen from its normal level of 7.5 to 1.5. The manufacturer claims that this drop in pH decreases motility from 95% to 0%. Semen samples were collected by masturbation from subjects to provide baseline data. 3 days after the initial sperm analysis, subjects were given 1 capsule of Contrasperm containing 10 mcg of the active ingredient. Additional semen analyses were conducted 30 minutes, 6 hours, and 24 hours after ingestion. Sperm count and sperm motility were greatly reduced in most subjects 30 minutes after ingestion. However, 6 subjects had increased sperm counts and 4 subjects demonstrated increased sperm motility, indicating an enhancing effect. At 6 hours after ingestion, 20 subjects had lowered sperm motility and 12 subjects showed normal sperm motility, contradicting the manufacturer's claim that motility is reduced to 0%. Although Contrasperm is claimed to be effective for 6-8 hours after ingestion, its effect wore off in less than 6 hours in 37% of subjects. Both sperm count and sperm motility returned to normal levels 24 hours after ingestion, confirming the reversibility of this drug. Most subjects reported mild side effects such as muscle weakness, blurred vision, dizziness, perspiration, urgency, abnormal muscle tension, and dry throat which persisted longer than 24 hours. Further studies, with proper controls, are needed to assess the reliability and toxicity of this preparation.
Which factors have the greater influence on family planning performance: fixed background variables such as racial composition, urbanization, and mortality, which are affected by level of development, or program inputs such as assignment of personnel and location of clinics, which are subject to manipulation by administrators? An analysis of differences in family planning acceptance among 70 districts of Malaysia shows that two main program-manipulable variables--level of personnel deployment and accessibility of clinics--have the largest direct effect upon acceptance levels. Variations in background factors explain a smaller proportion.
PIP: The application to the Malaysian family planning program of a conceptual model in which background factors, affected by the level of development, are distinguished from program input variables, subject to program manipulation, is considered in an effort to examine reasons for variations in program performance. Focus is particularly on the inputs of workers, who provide services and distribute supplies, and clinic facilities, through which services and supplies are made available. The questions asked concerned how their availability and use are affected by background factors, which themselves reflect to some extent the population's readiness to accept family planning. Distinguishing the program-manipulable factors from the background factors involved determination of the impact of both groups of variables, separately and together on levels of program acceptance, using appropriate bivariate and multivariate techniques. The evidence shows that in addition to background factors, over which program administrators can exercise no direct influence, there is a major contribution made to program acceptance through program factors over which the planner and administrator do have control. The 2 program variables contributed more in explaining performance levels than all 5 selected background variables combined, and the relative contribution of these program factors has increased over time. The key finding emerging from the different analyses is that program manipulable inputs are the dominant direct determinants of subsequent levels of family planning acceptance in Malayasia. Clearly, higher levels of development, as reflected in the measures of background variables, have facilitated acceptance, and background variables contributed significantly. Yet, whatever the level of development, the extent of deployment of program resources does significantly influence the level of program performance.
PIP: Analysis of family planning clinic services offered by the FFPA and its state Family Planning Associations in Malaysia in 1978 has shown that oral contraceptives continued to be the most popular contraceptive method among family planning acceptors, but there had been notable increases in acceptance of the condom and the IUD. There was a marginal decrease from 1977 figures in the acceptance rate among the new and continuing acceptors of OCs in Peninsular Family Planning Associations. 77.1% of new acceptors chose OCs in 1978, compared with 85.3% in 1977. 15% of the new acceptors chose condoms in Peninsular Family Planning Associations last year, compared with 10.2% in 1977. The injectable contraceptive has been well received in Sawawak; 14,681 vials were dispensed in 1978.
PIP: Responses to questions relating to breastfeeding in the World Fertility Surveys of South Korea, Indonesia, Nepal, Sri Lanka, Malaysia, and Bangladesh are analyzed. Of these countries, the percentage of ever-married women who had breastfed in the last closed interval was between 94-99%, except for Malaysia (81%) and average number of months breastfeeding took place was from 16.5-19.2, except for Malaysia (7.3). The infant mortality rate in these countries was 33/1000 live births for South Korea, 45/1000 for Malaysia, 51/1000 for Sri Lanka, 137/1000 for Indonesia, 150/1000 for Bangladesh, and 152/1000 for Nepal. Responses, however, might vary according to different interview situations. Assuming that the reporting errors are of similar magnitude and direction, the relationship between duration of breastfeeding and the birth interval can be studied. But it is possible that breastfeeding was prolonged due to other reasons for which conception was delayed; thus the regression of breastfeeding duration on the birth interval is not as logical as the regression of the birth interval on the breastfeeding is, especially when habitual breastfeeding can be avoided. The negative relationship between breastfeeding and infant mortality does exist, assuming that a woman breastfeeds all her children for similar durations. Some breastfeeding differentials are place of residence (less for rural areas), education (reduces duration), and religion (Christians have shorter duration than Muslims, Hindus, or Buddhists). In South Korea the mean length of breastfeeding of women aged 25-34 and 35-44 are 17.5 and 20.5, and women using contraceptives are 26% for 25-34 and 20% for 35-44. South Korea also has the highest level of breastfeeding, highest incidence of ever use of contraceptives, and a very low level of fertility. Nepal and Bangladesh have a high level of breastfeeding but since their contraceptive incidence is low, their fertility level remains high. Some areas of further research include influence of breastfeeding on infant and child mortality.
Analysis of World Fertility Survey data from five countries--Colombia, Costa Rica, Korea, Malaysia and Nepal--shows that the availability of contraceptive services and supplies is a major determinant of use. In Nepal, where few women know where to obtain supplies, only two percent are contracepting. In Costa Rica, where almost all married women know an outlet nearby, 53 percent use effective methods.
PIP: Organizational and content features of various national family planning programs are reviewed. The Thai program is cited as an example of a family planning program organized on a massive unipurpose compaign basis. The Korean and Taiwan programs have utilized special field workers while upgrading the general health care network. 3 major problems with family planning programs are: 1) the lack of experience with such programs; 2) lack of commitment at the highest political levels; and 3) medical conservatism. Utilization of all available contraceptive methods instead of reliance on 1 method would improve most programs. Nursing and auxiliary personnel could be trained to take over the work of physicians in family planning programs. This is already being done with IUD insertion and pill prescription in several programs. The postpartum tubal ligation approach has proven effective and should be extended. There is a place in all national programs for both the private and the commercial sectors. Incentives for clinics, personnel, and acceptors might spread family planning more rapidly.
PIP: Family planning in Malaysia is discussed. Family planning began in Malaysia about 15 years ago through the efforts of voluntary family Planning Associations in the various Malay states. In 1966 the Malaysian Parliament passed the National Family Planning Act setting up the National FAmily Planning Board to formulate policies and methods for the promotion and spread of family planning knowledge and practice on the grounds of health of mothers and children and welfare of the family. In 1967, the board set a target of 40,000 new acceptors of family planning and 90% of the target was reached. This represents 3% of the child-bearing married women aged 15-49. The target for 1968 of 65,000 new acceptors is being achieved. A survey of acceptors is to be carried out from December 1968 to April 1969 to ascertain how many women who accepted family planning continue to practice it. Malaysia's crude birth rate declined from 46.2 in 1957 to 37.3 in 1966 before the government program was instituted. Abortion attempts have been frequent. The main method of contraception used is oral contraceptives. According to a 1957 survey, 31% of the married women in the metropolitan areas and 2% of rural women were using contraception. Presently, in Malaysia there is a need to: 1) train personnel to provide services, 2) inform and motivate families to accept family planning, 3) continue a broad educational program, 4) reform Malaysia's antiquated abortion law, and 5) integrate family planning services more fully into the general health services of the country.
