The purpose of this study was to investigate the rate of pregnancy, abortion, delivery and contraceptive use and the relationship between the related factors and the early coitus among Korean teenagers. Method: The subjects of this study were 12,733 teenagers age 13-19 years in 7 major cities and 9 provinces in Korea. Data was collected from 2 Oct., to 28 Oct., 2000 and analyzed by using SPSS 10.0 Program. Results: The results showed pregnancy rate 4.5%, delivery rate 0.5%, abortion rate 0.4%. Adolescent girls who experienced coitus relatively went to vocational school, coeduaction school, night school in the general characteristics (p=0.000). Adolescent girls who experienced coitus tend to go to video room (18.5%), go the singing room (60.7%), the bar (54.8%), petting with the partner during the dates. There were overlapping juvenile delinquencies such as drinking (89.2%), pornography (65.3%), bond inhalation (2.7%), leaving homes (43.7%), smoking (14.5%), cyber sex (70.8%), phone sex (12.9%). Adolescent girls who experienced coitus were more suffering from Wangtta (26.1%) than who had not. They showed significant positive attitudes toward coitus; such as feeling of excitement (6.6%), nature (37.9%), beauty (8.7%). On the other hand, they had more guilty (2.8%) than the inexperienced (p=0.000). The main factors relating to early coitus were 'to confirm love' (46.9%), 'afraid of rejection' (32.2%). They think the benefits of coitus were 'more intimacy with boyfriends' (20.6%), 'satisfaction of curiosity' (16.8%). The losses on coitus were 'worry about pregnancy' (73.7%) and 'unability to refuse sexual contacts' (28.7%) Conclusion: It could be concluded that it is necessary to plan different sex education programs according to general characteristics and delinquency behaviors of teenage girls in Korea.

Objective: The goal of the present study was to investigate the rate of chromosomal aneuploidies in surplus embryos after sex determination at the cleavage stage. Then, the same chromosomal aneuploidies were evaluated in blastocysts after extended culture. Methods: Sixty-eight surplus embryos were biopsied at the cleavage stage and incubated for an additional 3 days to allow them to reach the blastocyst stage. The embryos were reanalyzed via fluorescence in situ hybridization (FISH) to examine eight chromosomes (13, 15, 16, 18, 21, 22, X, and Y) in both cleavage-stage embryos and blastocysts. Results: Although the total abnormality rate was lower in blastocysts (32.35%) than in cleavage-stage embryos (45.58%), the difference was not significant (p=0.113). However, when we restricted the analysis to autosomal abnormalities, we observed a significant difference in the abnormality rate between the cleavage-stage embryos (44.11%) and the blastocysts (17.64%, p=0.008). A higher rate of sex chromosomal abnormalities was also observed in cleavage-stage embryos (29.4%) than in blastocysts (14.70%, p=0.038). Conclusion: The data indicated that embryo biopsy should be conducted at the blastocyst stage rather than the cleavage stage. The results also emphasized that examination of common chromosomal aneuploidies apart from sex selection cycles can be conducted in the blastocyst stage with the FISH method.

Objective: To compare the pregnancy outcomes after in vitro fertilization with intracytoplasmic sperm injection (IVF-ICSI) between obstrucvtive and non-obstrucvtive azoospermia. Methods: From January 1994 to December 2002, 524 patients with obstructive azoospermia (886 cycles) and 163 patients with non-obstructive azoospermia (277 cycles) were included in this study. Microsurgical epididymal sperm aspiration (MESA) or testicular sperm extraction (TESE) in obstructive azoospermia and TESE in non-obstructive azoospermia were perfomed to retrieve sperm, which was used for ICSI and then fertilized embryos were transferred. The results of ICSI - fertlization rate (FR), clinical pregnancy rate (CPR), clinical abortion rate (CAR) and delivery rate (DR) - were statistically analysed in obstructive versus non-obstructive azoospermia. Results: There were no differences in the number of retrieved oocytes, injected oocytes for ICSI and oocyte maturation rate. FR was significantly higher in obstructive than non-obstructive azoospermia (71.7% vs. 61.1%, p<0.001). There was no difference in CPR per embryo transfer cycle. After pregnancy was established, however, CAR was significantly higher in non-obstructive than obstructive azoospermia (25.6% vs. 12.5%, p=0.004). DR per clinical pregnancy cycle was significantly higher in obstructive than non-obstructive azoospermia (78.0% vs. 64.4%, p=0.012). In the karyotype ananlysis of abortus, abnormal karyotypes were found in 75.0% (6/8) of obstructive and 55.6% (5/9) of non-obstructive azoospermia. Conclusion: Our data show significantly higher FR in obstructive than non-obstructive azoospermia. Though there was no differrence in CPR, CAR was significantly higher in non-obstructive than obstructive azoospermia. The abortion may be related to the abnormal karyotype of embryo, but further investigations are necessary to elucidate the cause of clinical abortion in azoospermia.

This study was conducted to investigate optimal time of artificial insemination (AI) to Hanwoo female after natural estrus. AI was occurred 12 and 24 hours after natural estrus in both heifer and multiparous recipient then pregnancy and parturition rates were estimated. Results indicated that AI performed at 24 hours after natural estrus showed significant (p<0.05) higher pregnancy rate in both heifer and multiparous recipient groups with significantly (p<0.05) higher abortion rate. However, there are no significant differences of parturition rate, twin birth and sex ratio in both heifer and multiparous recipient groups. Therefore, our results may suggest that performance of AI at 24 hours after natural estrus promise higher pregnancy rate than AI at 12 hours after natural estrus in both heifer and multiparous recipient.

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.

Habitual pregnancy loss has been defined as three or more consecutive spontaneous abortions. The rate of recurrent pregnancy loss is 2% to 5% of reproducible women. Half of this failure can be explained by genetic, hormonal, infectious, and anatomic factors. And eighty percent of the unexplained failures are proposed to have an immunologic cause. The antiphospholipid antibodies are characterized by prolonged phospholipid-dependent coagulation test (known as APTT or Russel viper venom), thrombosis, thrombocytopenia, and fetal loss. The association of antiphospholipid antibodies with one or more of these characteristic clinical features has been termed the antiphospholipid syndrome. We have experienced a case of successful live birth after treated a woman with heparin and aspirin who has experienced spontaneous abortion four times with antiphospholipid antibodies and present it with the review of literature.

Human chorionic gonadotropin(hCG) and intravenous immunoglobulin(IVIG) treatment were attempted as a novel therapeutic approach for unexplained recurrent spontaneous abortion(RSA). Forty-four and 3 women with a history of RSA were treated with hCG and IVIG, respectively, during pregnancy. Of these patients, serum blocking factor assay was performed before and after each treatment, in 15 patients; 12 cases with hCG and 3 cases with IVIG. The results were as follows: 1. Of 44 women who receive hCG during pregnancy, 24 delivered healthy infants at term, 10 patients suffered repeat abortion, and 10 women are still pregnant under 28 weeks. Over all success rate of hCG treatment was 70.6% (24/34). Although there is no statistical significance, absolute serm blocking level was decreased after treatment(N=12). 2. Of 3 women who receive IVIG during pregnancy, all 3 women are still pregnant under 28 weeks. Serum blocking level was increased after treatment, however, this increment was not statistically significant. Although no conclusion could be extracted from the patients who received IVIG, the therapeutic effect of hCG is comparable to that of the other therapeutic regimens, such as allogeneic leukocytes. It was postulated that actual etiology of unknown RSA would be classified as hormonal origin although combined etiologies are common in Korean women.
