Recently, during several years the number of ideal children have not changed at all. Because the most of Korean people considered that son is necessary absolutely for dependence in old age inheritance of family line and holding ritural and so on. Threfore, without revolution of value system for children we could no more expect to reduce fertility rate. The survey is intended to compare the characteristics between those women who want two or less number of ideal children and all married women(regardless the number of ideal children). The results showed as follows: The women who want small size of family were younger and little better educated than those of all married women. The age at marriage of women who want small size of family was older than that of all married women. The conducted rate of induced abortion and acceptance rate of contraception among those women who want small size of family were higher than those of all married women. The rate of those who want less than 2 children socalled ideal No. among all married women was 3.9 percent.

The paper provides a brief account of 11 plant species used by the tribal people of the district Purulia, West Bengal, India. Most of the plant species are common in this district and some have not been reported earlier for abortive purposes, pharmacology for preparation of medicines for antifertility. All these data were obtained from the tribal medicine men (ojha). At least 10 interview reports of various tribal medicine men were recorded. Parts of various medicinal plants were observed personally, collected and preserved as herbarium specimens for proper identification. The reports of various indigenous methods may help to give some clue in searching the potent contraceptives.

One of the major objectives in the developments of a progesterone I.U.D. is to prepare devices which release drug at a constant rate for extended periods. A constant release rate is achived by maintaining drug concentration at a constant valve via the introduction of rate limiting membrane to solute diffusion at the surface of the devices. In this study, progesterone dispersed at monolithic device were prepared from polyhydroxy ethyl methacrylate. Constant release rate were obtained with device which were soaked in on ethanol-hexan solution. The release rate was dependant upon the concentration of the ethanolic solution in the soaking solution. This devices offer significant potential for futher development of hydrogel in the intrauterine contraception device for controlled release of progesterone.

The testis is major male gonad responsible for spermatogenesis and steroidogenesis. Much knowledge is still remained to be learned about the control of these events. In this study, we performed a comprehensive bioinformatics analysis on 1,196 mouse testis proteins screened from public protein database. Integrated function and pathway analysis were performed through Database for Annotation, Visualization and Integrated Discovery (DAVID) and ingenuity Pathway Analysis (IPA), and significant features were clustered. Protein membrane organization and gene density on chromosomes were analyzed and discussed. The enriched bioinformatics analysis could provide clues and basis to the development of diagnostic markers and therapeutic targets for infertility and male contraception.

Sperm competent for fertilization can become capacitated, bind to the zona pellucida (ZP) of an egg in a specific manner, and complete acrosomal exocytosis. Failure to carry out these functions results in infertility. Although the interactions between the ZP and the plasma mem-brane overlying the sperm acrosome have been considered important for sperm-egg recognition and signalling, recent results have prompted a reassessment of current paradigms concerning these interactions. In this review, we're going to discuss about the roles of the acrosomal matrix, the particulate component of the acrosomal contents, in fertilization. The general hypothesis is that acrosomal exocytosis leads to the exposure of acrosomal matrix proteins that become de-facto extracellular matrix (ECM) on the surface of the sperm head, and that the dynamic interactions of this newly-exposed sperm ECM with the egg ECM (the ZP) govern sperm-egg recognition and sperm penetration of the ZP Informations from these experiments may provide new ways to address the poor ZP binding of sperm from some human infertility patients and may offer new avenues for contraception through the disruption of purposeful sperm-ZP binding.

Purpose: Aims of the researchers were to develop an birth control empowerment program (BCEP) designed to help married immigrant women in Korea to plan their pregnancies. Methods: This study was as a randomized controlled trial to verify the effects of the BCEP. The BCEP was developed based on Falk-Rafael (2001)'s Empowerment caring model. The program was offered once a week, for 90 minutes per session, for a total of 10 weeks. The BCEP incorporated group instruction, group discussion, and counseling. The eligible participants were randomly assigned to either experimental group (n=23) or control group (n=23). Results: Participants in the intervention group had significantly better outcomes in contraceptive knowledge (p<.001), contraceptive self-efficacy (p=.014), perceived contraceptive control (p<.001), sex-related spousal communication (p<.001), and sexual autonomy (p=.009). Conclusion: The BCEP was effective intervention method, which can promote family planning practices among married immigrant women.

Root barks of Paeonia suffruticosa Andrews (PS) was reported as contraindicated drugs of pregnancy by many Korean medical classics. Recently, a major ingredient component of PS, paeonol was reported that has contraceptive effect on early pregnancy in rats. However, the accurate molecular mechanism is not clear. In this study, we showed that PS decreased the expression of receptor for leukemia inhibitory factor (LIFR) in human endometrial Ishikawa cells at non-toxic dose, although the expression of leukemia inhibitory factor (LIF) was increased by PS. In addition, PS inhibited the adhesion of human trophoblastic JAR cells onto Ishikawa cells. Given importance of LIF-LIFR signaling pathway in the process of embryo implantation, the decreased LIFR expression by PS will be a good explanation on the PS- or its ingredient compounds-induced contraception.

The purpose of this study is to provide fundamental information for the development of new sex education image media through the analysis of those tools produced by Planned Parenthood Federation of Korea. Twenty three video tapes related to the sex education were analysed. The data were sampled on the basis of the sex education instructions for primary and secondary schools published by the Seoul Office of Education in 1996 and the list of sex education information composed by the Planned Parenthood Federation of Korea with the following requirements. 1) The education materials are oriented to the middle and high school students as well a juveniles and are being used in public health centers and schools. 2) The education materials are not confined to the single subject such as AIDS or contraception. Because this study is focused on the analysis of image media, an analysis method widely and effectively used in public media study was chosen. The frequency analysis and percentage treatment were done by an SAS program. The results of the study are as follows : 1. An analysis of the material structure type showed that the frequency of the following subjects in 15 video tapes, composed as drama and cartoon, had this decreasing orde : sex behavior, sex relation ships, sex health, human development, personal technique, and society and culture. 2. The eight tapes of explanation and counseling showed a different sequence from that of the drama and cartoon material, primarily treating human development with 5419 seconds (47.9%) of type. The following were also considered in decreasing order: at 2000seconds (17.6%) sex behavior, at 1366 seconds (12.1%) sex health, at 1240 seconds (11.0%) society and culture, at 667 seconds (6.0%) relation ships, and at 611 seconds (5.4%) personal technique. 3. In a thematic analysis those education materials dealing with human development show this frequency sequence: anatomic physiology, reproduction, and adolescence. In relation, ships the sequence is dates, love, marriage and vows, and family. For personal technique, it is expressed as asking for help, and an empnasis on moral values. For sex behavior, they focus on abstinence, the co-responsibility of sex behavior, the sexual response of the human, and sexual nightmares. For the sex health area, the focus is contraception with abortion and reproductive health following that. In society and culture diversity is considered. 4. An analysis of the differences in production and content between 1980s and 1990s was also done. For materials produced in the 1980s the frequency of the subjects follows this order: sex behavior, human development, relation ships, sex health, personal technique, and society and culture with sub subjects such as abstinence, dating, adolescence, anatomic physiology, reproduction, calls for help, and the sexual response of a human being. For materials produced in the 1990s, highest frequency was sex behavior, the same as the 1980s. The rest of the material follows this decreasing order: relationships, human development, sex health, society and culture, and personal technique with sub subjects such as dating, co-resposibility in sex behavior, abstinence, and love frequently considered.

Rapid socio-cultural and economic changes in the country has brought with it changes in the society's value system. For a traditional society that is increasingly being exposed to modernization but where sex norms are still very restrictive, the adolescent sexual mores takes on added significance. Adolescents are caught between two opposing forces, the changing environment that allows for freer and liberal mores and the traditional society that cannot keep pace with the changing environment and therefore demands resistance to changes. This paper focuses on problems of adolescent sexuality in this country and considers the countermeasures for the existing problems. Amongst the problems are: (a) increasingly younger age of the adolescents who start sexual intercourse (b) non-use of contraception, (c) unwanted pregnancies, (d) increase in the number of induced abortion and (e) increase in the number of unwanted children and unmarried mothers. The Korean adolescent's sexual behavior seems to follow that of the developed countries. In other words, many western modes of life and sexual values seem to bave been copied in Korea and yet Korean adolescents lack in their knowledge of sex related matters such as reproductive physiology and contraception. Among middle and high school students, female students are reported to have less knowledge on sex than male students according to a 1988 survey by KIPH. Even among the unmarried famale factory workers, only 42.5 percent replied they know of the condom, and 25.1 percent and 23.1 percent said they had knowledge of spermicide and menstrual regulation respectively. However, 14.9 percent and 13.9 percent reported that they had a knowledge of the loop and female sterilization respectively according to the 1984 study by KIPH. Among the middle school students 0.8 percent said they had experience in sexual intercourse, while 7.3 percent of the high school students reported having had sexual intercourse. The sexual intercourse experience rate among the unmarried female factory workers is 37.8 percent. Among those female factory workers with sexual experience, 46.7 percent had more than one sex partners. Only 39.1 percent of male students and 18.9 percent of female students among those with sexual intercourse experience have used contraceptives. mostly condoms and oral pills 45.1 percent of female factory workers with sexual intercourse experience used contraceptives such as pills, condoms and rhythm methods. The pregnancy experience rate among the female factory workers who had experience in sexual intercourse is 29.5 percent, which is 11.1 percent among the total respondents. Out of the 102 pregnant female workers, 98 workers(96.1 percent) terminated their pregnancy by induced abortion and 2 workders(2 percent) in natural abortion, while 1 worker(1 percent) was in pregnancy and another 1 worker had normal birth that was subsequently sent to orphanage. In order to cope with the problem of adolescent sexuality, a drastic and strong policy measures should be taken by the government. The most effective countermeasure to the adolescent sexual problems appears to the education. The sex and population education in the school is very much in need. In addition, sex education program through mass media and at the job sit-should be promoted for a healthy development of adolescents' sexual behavior. Also, the existing national family planning program, which has focused on the married couples, should be extended to the unmarried people in its scope and contents of the program.
