Objective: To investigate the value of stimulated intrauterine insemination (IUI) in women with unilateral tubal occlusion. Methods: Superovulation and IUI was performed during 2003-2010 and the medical records were reviewed retrospectively. Thirty-seven infertile women (52 cycles) with unilateral tubal occlusion diagnosed by hysterosalpingography and without other causes of infertility were selected. One-hundred fourteen patients with unexplained infertility served as a control group (182 cycles). The main outcome was the clinical pregnancy rate per cycle. Results: The pregnancy rate per cycle was similar, 17.3% for the unilateral tubal occlusion group and 16.5% for the unexplained infertility group. The rate of miscarriage (11.1% vs. 23.3%) and ectopic pregnancy (11.1% vs. 6.7%) was similar between the two groups. The pregnancy rate was higher in patients with proximal occlusion (25.0%) compared with distal occlusion (13.9%) or unexplained infertility, but not statistically significant. Conclusion: Stimulated IUI can be suggested as the initial treatment option in women with unilateral proximal or distal tubal occlusion.

We have reviewed the pregnancy rate and outcome of 130 patients who underwent tubocornual anstomosis for correction of proximal tutal occlusion at Dong San Medical Center between September 1983 to May 1994. Tubal occlusion was the result of previous tubal sterilization in 115 patients(99 laparoscopic electrocautery, 16 laparoscopic ring, 1 tubal ligation with partially segmental resection and previous tubal infection in 14. Sixty four of the patients conceived(61.5%). Viable pregnancy was achieved in fifty patients (48%), tubal pregnancy in six (5.7%) and spontaneous abortion in eight(6.1%). No significant difference in pregnancy rates was found between patients with diseased cornua and those previously sterilized by either electrocautery or tubal ligation. We conclude that tubocornual anastomosis still remains the treatment of choice for patients with proximal tubal obstruction.

This study was carried out to provide the basic information for the implementation of population quality policies by analyzing fetal life. The outcomes and process of all the pregnancies of women with spouses living in Gapyung-gun, Kyunggi province from November 3, 1993 through December 31, 1995 were analyzed. The results of the study are as follows: According to the fetal life table, the estimated probability of pregnancy outcome showed 53.5% of live birth, 14.5% of fetal death, 32.0% of induced abortion, which resulted in 46.5% of pregnancy wastage throughout gestation period. The curve of the estimated probability of pregnancy outcome by gestation weeks showed L shape in case of total pregnancy rate, induced abortion rate and fetal death rate. The estimated probability of fetal death was 21.9% in case that the induced abortion was excluded, which was 7.4% higher than the case that induced abortion was included. The expected duration of pregnancy was 22.9 weeks until the fourth week of gestation and then started to become the highest, 26.6 weeks at the tenth week. At the 11th week, it declined to decrease to 26.4 weeks. This is attributed to the fact that the pregnancy wastage including fetal death and induced abortion occurred in the early period of pregnancy. The establishment of appropriate policies to cope with this situation are needed.

Objective This study aimed to develop a nomogram that predicts ongoing pregnancy after in vitro fertilization and embryo transfer (IVF-ET) using patient age and serum hormonal markers. Methods A total of 284 IVF-ET cycles were retrospectively analyzed. At 14 days post-oocyte pick-up (OPU), the serum human chorionic gonadotropin (HCG) and progesterone levels were measured. The main predicted outcome was ongoing pregnancy. Results Patient age and serum of HCG and progesterone levels at 14 days post-OPU were good predictors of ongoing pregnancy. The cut-off value and area under the curve (AUC) (95% confidence interval) were 36.5 years and 0.666 (0.599-0.733), respectively, for patient age; 67.8 mIU/mL and 0.969 (0.951-0.987), respectively, for serum HCG level; and 29.8 ng/mL and 0.883 (0.840-0.925), respectively, for serum progesterone level. When the prediction model was constructed using these three parameters, the addition of serum progesterone level to the prediction model did not increase its overall predictability. Furthermore, a high linear co-relationship was found between serum HCG and progesterone levels. Therefore, we developed a new nomogram using patient age and HCG serum level only. The AUC of the newly developed nomogram for predicting ongoing pregnancy after IVF-ET cycles using patient age and serum HCG level was as high as 0.975. Conclusion We showed that ongoing pregnancy may be predicted using only patient age and HCG serum level. Our nomogram could help clinicians and patients predict ongoing pregnancy after IVF-ET if the serum JCG level was ${\geq}5IU/L$ at 14 days post-OPU.

The survey was conducted to investigate several factors affecting the disease outcome with 116 infants aged 10 to 24 months residing in Kunsan city, Cheonbuk province . General characteristics, weaning practice , nutrient intake and the actual state for affecting disease were studied. Among many factors, mother's educational status was found to be the most influencing factor for affecting the disease outcome analyzed by oneway ANOVA. The exposure index disease, cold and diarrrhea, against mother's education were analyzed to find out the major factors for disease outcome. The education group up to middle school graduates, mother's job , nutrients supplements, feeding method, sex of baby were the factors, for the high school graduates, job , nutrients supplements were the causes, and the group graduated from the college the above grade mother's health state was the most important factor for the baby exposing to the disease. The disease outcome decreased when the bottle feeding was replaced by breast feeding, sufficient nutrients supplementation was recommended , and health care for mother during pregnancy was strongly advised.

This study was performed to determine if women with day 3 serum inhibin-B concentrations <45pg/ml (conversion factor to SI unit, 1.00) demonstrate a poor response to ovulation induction and assisted reproductive technology outcome to women with inhibin-B${\ge}45pg$/ml, independant of day 3 FSH, E2 and patient age. From Jan 1996 to Dec 1996, 16 volunteers patients who underwent 25 IVF cycles with luteal phase GnRH agonist suppression and HMG stimulation were allocated to the study group. We evaluated day 3 serum inhibin-B, FSH, E2, peak E2, cancellation rate per initiated cycle (%) and clinical pregnancy rate per initiated cycle (%) according to the above two groups and independent of patient age, day 3 FSH, day 3 E2 and all of above combined. Women with day 3 serum inhibin-B${\ge}45pg$/ml demonstrated higher average day 3 inhibin-B level, clinical pregnancy rate per initiated cycle ($20.3{\pm}2.5$ pg/ml vs $80.9{\pm}5.0$ pg/ml, p<0.05; 24.8% vs 8.5%, p<0.05) and lower day 3 FSH level, cancellation rate per initiated cycle ($6.9{\pm}0.3$ mIU/ml vs $8.5{\pm}0.5$ mIU/ml, p<0.05; 1.5% vs 9.0%, p<0.05). Women with day 3 serum inhibin${\ge}45pg$/ml and age<40 year demonstrated higher pregnancy rate per initiated cycle (28.2% vs 7.4%, p<0.05) and lows. day 3 FSH level, cancellation rate per initiated cycle ($6.9{\pm}0.5$ mIU/ml vs $8.2{\pm}0.7$ mIU/ml, p<0.05; 1.0% vs 9.0%, p<0.05). Women with day 3 serum inhibin${\ge}45pg$/ml and day 3 FSH<15mIU/ml demonstrated higher pregnancy rate per initiated cycle (33.5% vs 9.5%, p<0.05) and lower day 3 FSH level, cancellation rate per initiated cycle ($7.7{\pm}0.2$ mIU/ml vs $8.5{\pm}0.5$ mIU/ml, p<0.05; 1.5% vs 10.0%, p<0.05). Women with day 3 serum inhibin${\ge}45pg$/ml and day 3 E2<50pg/ml demonstrated higher pregnancy rate per initiated cycle (30.0% vs 9.5%, p<0.05) and lower cancellation rate per initiated cycle (1.5% vs 9.5%, p<0.05). Women with day 3 serum inhibin${\ge}45pg$/ml, age<40 year, day 3 FSH<15mIU/ml and day 3 E2<50pg/ml demonstrated higher pregnancy rate per initiated cycle (30.0% vs 10.8%, p<0.05) and lower day 3 FSH level, cancellation rate per initiated cycle ($6.8{\pm}0.6$ mIU/ml vs $8.4{\pm}0.9$ mIU/ml, p<0.05; 1.5% vs 7.8%, p<0.05). Therefore women with low day 3 serum inhibin-B concentrations demonstrate a poorer response to ovulation induction and are less likely to conceive a clinical pregnancy though ART relative to women with high day 3 inhibin-B and day 3 serum inhibin-B, in addition to a day 3 FSH, E2 and patient age, appears helpful in prediction in IVF-ET outcome.

Purpose: The aim of this study was to determine the influence of various factors on preterm labor symptoms (PLS) and preterm birth (PB). Methods: This prospective cohort study included 193 women in the second stage of pregnancy. Multiple characteristics including body mass index (BMI), smoking, and pregnancy complications were collected through a self-report questionnaire. Pregnancy stress and PLS were each measured with a related scale. Cervical length and birth outcome were evaluated from medical charts. Multiple regression was used to predict PLS and logistic regression was used to predict PB. Results: Multiple regression showed smoking experience, pregnancy complications and pregnancy specific stress were predictors of PLS and accounted for 19.2% of the total variation. Logistic regression showed predictors of PB to be twins (OR=13.68, CI=3.72~50.33, p<.001), shorter cervix (<25mm) (OR=5.63, CI=1.29~24.54, p<.05), BMI >25 ($kg/m^2$) (OR=3.50, CI=1.35~9.04, p<.01) and a previous PB (OR=4.15, CI=1.07~16.03, p<.05). Conclusion: The results of this study show that the multiple factors affect stage II pregnant women can result in PLS or PB. And preterm labor may predict PB. These findings highlight differences in predicting variables for pretrm labor and for PB. Future research is needed to develop a screening tool to predict the risk of preterm birth in pregnant women.

Purpose: : The purpose of this study was to evaluate the intrauterine insemination (IUI) success rate and to define the variables for predicting success. Methods: The secondary data analysis was used with data collected from infertile females who underwent IUI in Fertility and IVF (In Vitro Fertilization) clinics, who benefited from the 'National Medical-aid Program for ART (assisted reproductive technology) in 2016', in which the data of 34,920 IUI cases were retrospectively reviewed. The primary outcome measure was the clinical pregnancy rate in elderly and young infertile females. Data were analyzed by descriptive statistics, χ2 test and logistic regression. Results: The pregnancy rate was 12.1% (2,095 cases) in elderly infertile females and 15.6% in young infertile females (2,758 cases) (χ2 = 87.90, p< .001). Using the logistic regression analysis, clinical pregnancy was positively associated with the ovulatory factor (OR= 1.48, p< .001) and male factor (OR= 1.19, p< .05) in elderly infertile females. It was positively associated with the ovulatory factor (OR= 1.30, p= .001) and the peritoneal cavity factor (OR= 0.58, p< .05) in young infertile females. Conclusion: Our results indicate that the pregnancy rate in young infertile females was higher than that in old infertile females, and the IUI is the effective option in pregnancies in all ages with infertility due to the ovulatory factor. Additionally, further studies are necessary to fully describe pregnancy experiences for all the infertile females.

Objective: The aim of this study was to compare the pregnancy outcomes of in vitro fertilization with embryo transfer between embryos cultured in a time-lapse monitoring system (TLS) and those cultured in a conventional incubator (CI). Methods: The medical records of 250 fertilized embryos from 141 patients undergoing infertility treatment with assisted reproductive technology at a tertiary hospital from June 2018 to May 2020 were reviewed. The study population was divided into TLS and CI groups at a 1 to 1 ratio (125 embryos per group). The primary outcome was the live birth rate. Results: The TLS group had a significantly higher clinical pregnancy rate (46.4% vs. 27.2%, p=0.002), implantation rate (27.1% vs. 12.0%, p=0.004), and live birth rate (32.0% vs. 18.4%, p=0.013) than the CI group. Furthermore, subgroup analyses of the clinical pregnancy rate and live birth rate in the different age groups favored the TLS group. However, this difference only reached statistical significance in the live birth rate in women aged over 40 years and the clinical pregnancy rate in women aged 35-40 years (p=0.048 and p=0.031, respectively). The miscarriage rate, cleavage rate, and blastocyst rate were comparable. Conclusion: TLS application improved the live birth rate, implantation rate, and clinical pregnancy rate, particularly in the advanced age group in this study, while the other reproductive outcomes were comparable. Large randomized controlled trials are needed to further explore the ramifications of these findings, especially in different age groups.
