Total fertility rate in South Korea is the lowest in the world. A fertility rate below replacement fertility level will result in serious social problems in the long term. Therefore, it is worthwhile to study a general understanding about the low fertility rate phenomenon and to investigate the effectiveness of fertility policies in order to ameliorate the resulting social problems due to the low fertility rate. This research was a descriptive examination into the low fertility rate phenomenon and an investigation of the needs for fertility potties and their effectiveness. The study subjects were consisted of 769 unmarried people aged from 18 to 40 years old. Data were collected from June to August 2004 and were analyzed by frequencies, mean, and standard deviation. The following results were revealed. First, unmarried people in general had positive perspectives about getting marriaged, giving birth, and being a parent. In addition, the primary cause of low fertility rate was economical difficulties for raising a child. Third, unmarried people thought that the low fertility rate phenomenon resoled in both positive and negative changes in a society. Fourth, policies for economical supports for raising children, establishing social atmosphere for gender equality, and trustful public educational systems were the political alternatives that people really wanted for having a child in the future. Effective alternatives for policies and strategies to address the low fertility rate problems are suggested in the discussion section.

Fertility has been declined since 1966 (see Table 1). This fertility reduction was duely caused by age at first marriage, induced abortion and contraceptive practice which has been largely increased in recent years. Although tbe proximate determinant such as induced abortion, age at marriage and breastfeeding can and do have an effect on fertility, the principal cause of the reduction in fertility in Korea during the fertility transition can be supported by correlation between level of fertility and contraceptive prevalence (See Fig. 4). Taking a regression equation between fertility (TER. Y) and prevalence level (X), the total fertility rate in 1984 was estimated as 1.9 and 2.1 based on lenear and expotential function shown as follow; $Y_1$=5.709-0.0549 X and $Y_2$_______80________ 1+e2.433+0.017X ($R^2$=O. 93) ($R^2$=0. 96) Where $Y_1$ and $Y_2$ denote total fertility rates obtained through two equations respectivelly. The peak of contraceptive prevalence was assumdd as 80 percent which is almost upper limit in human society. On the other hand, an observed value of 1984 fertility level obtained from five month period shows 2.1 which is coincident with logistic fitting after the adjustment of response error assumed around 10 to 20 percent, At any rate, fertility of Korean women will have been reached replacement level (2.1) by 1985.Thus policy for family planning program must be reviewed toward the direction of integrated approach particularly with MCH program inasmuch as fertility in Korea has already shown population replacement level that require more good quality of service in family planning and their There must be an advanced level of fertility in Korea because wide use of contraception and induced life abortion and age at marriage will effect modern fertility which shows up and down trend between 2.1 and 1.5 in general.

The fertility rate of Korea has rapidly decreased to the lowest in the World. The fertility rate below replacement fertility level might result in many social problems. First, this study investigated the cause of low fertility rate. Second, the theories of the relationship between fertility rate and women's employment were reviewed. The previous studies suggested that the fertility rate was not always related to women's employment negatively and there was mediating factors between them. Third, the various factors that mediated the negative relationship between fertility rate and women's employment were described in personal, family and social levels. Finally, this study suggested the policies and strategies to solve the low fertility rate problem in Korea.

This study examines the socioeconomic determinants of fertility behavior in Korea by developing a model which simultaneously takes into account both individual and community-level differences. It especially focuses on the micro-macro nexus of fertility behavior depending on social contexts. This study utilizes micro data obtained from the 1974 Korean National Fertility Survey(KNFS), and macro data obtained from Korean government statistics. The framework of the model is formalized as a set of structural equations modelling the fertility process. The model is formed on a cohort-specific processual basis and is restricted to five-year birth cohorts. Three cohorts of women are studied : those aged 30-34, 35-39, and 40-44. The model includes three fertility-process components : age at first birth, early fertility, and later fertility, which are defined by reference to the age of the mother. The results of this study indicate that socioeconomic development in Korea results in increased age at first birth and reduced numbers of children per couple. In addition to the developmental change, Korea's fertility decline is found to be facilitated by family planning programs. As expected, the effect of family planning on fertility is greater among better-educated women than among poorly educated women. The inconsistent but suggestive result, however, is that the effect of socioeconomic development on fertility is greater among less-privileged women than among more-previleged women.

The low fertility rate and the unprecedented rapid pace of population aging is a significant factor degrading the national competitiveness and the social security system of Korea. The government has implemented various maternity incentives to alleviate the low birth problem; however, the policy seems in effective to solve the problem of low fertility. This study proposes a conditional birth-order specific fertility rate and investigates the policy effects of fertility transition in Korea to provide a basis for more effective policy development. The use of a conditional birth-order specific fertility rate allows for an effective calculation of the change and the effect in total fertility rate than a birth-order specific fertility rate. We compare the effects of the total fertility rate according to various scenarios that enables us to calculate how the total fertility rate can achieve the current multi-child childbirth support policy of the government and estimate how the total fertility rate can be achieved when focusing on the first or second childbirth support policy. We also summarize the research results on policy development for a practical increase in the childbirth that considers the rapid decrease in women of childbearing age (15-49 years) due to continued low fertility and present the number of childbirths in accordance with the total fertility rate.

This study was designed to make a comparative analysis of fertility control policies in developing countries selected from Asia and Latin America. Considering the size and the density of population, the history of the fertility control policy, and the availability of references, eight countries were chosen among Asian developing countries that have adopted the fertility control as an official policy. All of nine countries in Latin America that have adopted family planning as an official policy were included in this study. An attempt was made to formulate an analytical framework to be used for a comparative analysis of fertility control policies. It can be represented by a continuum which consists of individual approaches and structural approaches to fertility control at both extremes. It represents fairly well the controversies between those who advocate family planning and those who advocate measures beyond family planning, but assumes that the two sides of the controversy form a continuum of approaches to fertility control. Various fertility control policies of each country were placed along this continuum and analyzed. The results of the analysis can be summarized as follows: (a) Those countries that have higher population pressure in terms of either the size of population or the population density tend to adopt fertility control policies earlier in time. (b) Those countries that have higher population pressure in terms of either the size of population or the population density tend to adopt more comprehensive measures along the continuum of fertility control policies. (c) Those countries that adopted more comprehensive measures along the continuum seem to have succeeded in reducing their level of fertility more effectively. (d) Developing countries in Asia tend to adopt more comprehensive measures to control fertility than those in Latin American countries. (e) The reduction of fertility in developing countries seems to be associated with both the fertility control policies and the level of socioeconomic development.

In this study, pooled whole semen and diluted semen with skim milk lactose solution and yolk skim milk lactose solution were inseminated at 6 and 7 days interval during 90 days. Egg production, fertility and hatchability were investigated. The results obtained from this study are summarized as following: 1. The average fertility of 57.8% for whole semen was clearly higher than that of 35.2% for diluted semen during 90 days insemination trial. 2. The highest fertility was a, pp.ared from 35 to 99 days after insemination for the whole semen, but from 28 to 60 days for the diluted semen during 90 days insemination trial. 3. In case of 7 days insemination interval, highest fertility of 86.6 and 70.0% for the whole semen and the diluted semen was a, pp.ared on 2 days after insemination and thereafter the fertility was gradually decreased according to passage of insemination. The lowest fertility of 35.0 and 0.0% for the whole semen and diluted semen was a, pp.ared on 1 day after insemination. 4. In case of 6 days insemination interval, highest fertility of 80.0 and 55.8% for the whole semen and the diluted semen was also a, pp.ared on 2 days after insemination and thereafter the fertility was slowly decreased according to passage of insemination. However, lowest fertility of 25.0 and 20.0% for the whole semen and the diluted semen was a, pp.ared on 0 day after insemination. 5 It suggests that there was no difference in fertility between the skim milk lactose and the yolk skim milk lactose dilutors. 6. In case of whole semen, average fertility of 7 days insemnaition interval was a, pp.rently lower than that of 6 days, however there was no difference in fertility between 6 and 7 days insemination interval. 7. Insemination interval of 6 and 7 days and passage day after insemination did not alter egg production and hatchability of fertilized egg production and hatchability of fertilized egg in both whole and diluted semen.

The purpose of this study is to identify the important marriage variables influencing fertilty. The data on which this study is based was selected from the survey data which was nation-widely collected from 2,824 married women in 1989 as the Korean. Family Function Study performed by the Korea Institute for Population and Health. The data was analyzed by the methods such as Cross Tabulation, Pearson's Correlation, and Multiple Regression. And the data analysis was processed by SPSS. The results are as follows. 1. There are differences in fertility according to the socioeconomic factor. The higher the educational level of a married woman is the lower the fertility level. And if the decision of marriage was made by herself, the fertility level is significantly low. As the duration of living in a large city is longer and the educational level of her husband is higher, the fertility level is low. 2. There are differences is fertility according to the demographic factor. As the first marriage age of her and her husband, the fertility level was low. And when a couple doesn't live with the husband's parents and the size of a family is small, the fertility level is low. 3. Finally the factors affecting fertility were analyzed by the Stepwised Multiple Regression. The result shows that as the educational level of a married woman is higher, she herself decides the marriage, the first marriage level of her is higher, the size of a family is small, her husband is higher, the fertility level is low.

Obstructive azoospermia caused by acute epididymitis is usually permanent, and microsurgical vasoepididymostomy is the only reconstructive treatment option. There have been no reports of delayed recovery of sperm count after over 1 year in a patient with obstructive azoospermia related to history of acute epididymitis. We present a young male patient who had azoospermia and a history of acute epididymitis who experienced delayed recovery, with complete restoration of sperm production and the ability to conceive naturally.
