TL;DR: The evidence in the demographic and family planning literature of the range and diversity of the barriers to fertility regulation in many developing countries is reviewed in this article from a consumer perspective.
Abstract: The evidence in the demographic and family planning literature of the range and diversity of the barriers to fertility regulation in many developing countries is reviewed in this article from a consumer perspective. Barriers are defined as the constraining factors standing between women and the realistic availability of the technologies and correct information they need in order to decide whether and when to have a child. The barriers include limited method choice, financial costs, the status of women, medical and legal restrictions, provider bias, and misinformation. The presence or absence of barriers to fertility regulation is likely an important determinant of the pace of fertility decline or its delay in many countries. At the same time, barriers inhibit women's ability to avoid unintended pregnancy. Problems of quantifying barriers limit understanding of their importance. New ways to quantify them and to identify misinformation, which is often concealed in survey data, are needed for future research.

TL;DR: The evidence for the effect of access to reproductive health services on the achievement of Millennium Development Goals 1, 2, and 3, which aim to eradicate extreme poverty and hunger, achieve universal primary education, and promote gender equality and empower women, is considered.

TL;DR: Fertility was not affected by the husband's smoking, and data provide evidence that reduced fertility should be added to the growing list of reproductive hazards of cigarette smoking.
Abstract: We conducted an epidemiologic study to test the hypothesis that women who smoke have reduced fertility. Data on smoking history and number of noncontracepting cycles until conception were collected from 678 pregnant women. Thirty-eight percent of nonsmokers conceived in their first cycle compared with 28% of smokers. Smokers were 3.4 times more likely to have taken greater than a year to conceive compared with nonsmokers. After adjusting for potential confounding variables by Cox proportional hazards regression, fertility of smokers was estimated to be 72% of the fertility of nonsmokers. Heavy smokers experienced lower fertility than did light smokers (57% and 75% of the pregnancy rate of nonsmokers, respectively). Fertility was not affected by the husband's smoking. These data provide evidence that reduced fertility should be added to the growing list of reproductive hazards of cigarette smoking. ( JAMA 1985;253:2979-2983)

TL;DR: The hazard of disruption has strong negative effects on the hazard of marital childbearing, lengthening the intervals between births and decreasing the chances that a child will be born.
Abstract: Married couples with children appear to be less likely to end their marriages than childless couples, especially when the children are young. Although this suggests that children affect the chances that their parents will divorce, the process may not be so simple: the chances that the marriage will last also may affect couples' willingness to make the commitment to the marriage implied by having children. This paper uses data from the Panel Study of Income Dynamics (PSID) to test the hypothesis that the risk of disruption faced by a married woman affects the chances that she will conceive and bear a child. The model used takes into account the simultaneous relationships between marital dissolution and marital fertility by including the hazard of disruption as a predictor of timing and likelihood of marital conception, and by including the results of previous fertility decisions as predictors of disruption of the marriage. We find that the hazard of disruption has strong negative effects on the hazard of marital childbearing, lengthening the intervals between births and decreasing the chances that a child will be born. This effect appears to be strongest for women who have had at least one child, either before or during the current marriage, although it is also large for childless women. Explicitly including the hazard of disruption in models of marital childbearing has sizable and important effects on many predictors of fertility.

TL;DR: The main finding about aggregate prediction is that 1970 intentions overestimated 1971–1975 fertility to the same extent as the conventional 1970 total fertility rate.
Abstract: On the basis of data collected in the 1975 National Fertility Study (NFS) in which continuously married white women interviewed in the 1970 NFS were reinterviewed five years later, the aggregate and individual validity of reported fertility intentions is evaluated. The main finding about aggregate prediction is that 1970 intentions overestimated 1971–1975 fertility to the same extent as the conventional 1970 total fertility rate. The conclusion is that intentions suffer all of the same vulnerabilities as other period measures. At the individual level, the validity of intentions is considerable in comparison with most other indicators.
