OBJECTIVES: Klinefelter syndrome is the most common genetic cause of male infertility and presents with 47, XXY mainly or 46, XX/47, XXY mosaicism. It is characterized by hypogonadism and azoospermia due to testicular failure, however, sporadic cases of natural pregnancies have been reported. With the development of testicular sperm extraction (TESE) and intracytoplasmic sperm injection (ICSI), sperm can be retrieved successfully and ART is applied in these patients for pregnancy. It has been suggested that the risk of chromosome aneuploidy for both sex chromosome and autosome is increased in the sperms from 47, XXY germ cells. Considering the risk for chromosomal aneuploidy in the offspring, preimplantation genetic diagnosis (PGD) could be applied as a safe and more effective treatment option in Klinefelter syndrome. The aim of this study is to assess the outcome of PGD cycles by using FISH for sex chromosome and autosome in patients with Klinefelter syndrome. MATERIALS AND METHODS: From Jan. 2001 to Dec. 2003, PGD was attempted in 8 cases of Klinefelter syndrome but TESE was failed to retrieve sperm in the 3 cases, therefore PGD was performed in 8 cycles of 5 cases (four 47, XXY and one 46, XY/47, XXY mosaicism). In one case, ejaculated sperm was used and in 4 cases, TESE sperm was used for ICSI. After fertilization, blastomere biopsy was performed in 6~10 cell stage embryo and the chromosome aneuploidy was diagnosed by using FISH with CEP probes for chromosome X, Y and 17 or 18. RESULTS: A total of 127 oocytes were retrieved and ICSI was performed in 113 mature oocytes. The fertilization rate was 65.3+/-6.0% (mean+/-SEM) and 76 embryos were obtained. Blastomere biopsy was performed in 61 developing embryos and FISH analysis was successful in 95.1% of the biopsied blastomeres (58/61). The rate of balanced embryos for chromosome X, Y and 17 or 18 was 39.7+/-6.9%. The rate of aneuploidy for sex chromosome (X and Y) was 45.9+/-5.3% and 43.2+/-5.8% for chromosome 17 or 18, respectively. Embryo transfer was performed in all 8 cycles and mean number of transferred embryos was 2.5+/-0.5. In 2 cases, clinical pregnancies were obtained and normal 46, XX and 46, XY karyotypes were confirmed by amniocentesis, respectively. Healthy male and female babies were delivered uneventfully at term. CONCLUSION: The patients with Klinefelter syndrome can benefit from ART with TESE and ICSI. Considering the risk of aneuploidy for both sex chromosome and autosome in the sperms and embryos of Klinefelter syndrome, PGD could be offered as safe and more effective treatment option.

OBJECTIVES: The risk of aneuploidies of embryos increases in advanced maternal age or parental karyotype abnormality and it results in poor reproductive outcomes such as recurrent spontaneous abortion (RSA) or repeated implantation failure (RIF). Preimplantation genetic diagnosis for aneuploidy screening (PGD-AS) can be applied for better ART outcome by selecting chromosomally normal embryos. The aim of this study is to evaluate the clinical outcome of PGD-AS and which group can get much benefit from PGD-AS among the patients expected to have poor reproductive outcome. METHODS: In 42 patients, 77 PGD cycles were performed for aneuploidy screening. Patients were allocated to 3 groups according to the indication of PGD-AS: group I-patients with old age (> or =37) and RIF more than 3 times (n=11, mean age=42.2 yrs.), group II-patients with RSA (> or = 3 times) associated with aneuploid pregnancy (n=19, mean age=38.9 yrs.), group III-parental sex chromosome abnormality or mosaicism (n=18, mean age=29.6 yrs.) including Turner syndrome, Klinefelter syndrome and 47,XYY. PGD was performed by using FISH for chromosome 13, 16, 18, 21, X and Y in group I and II, and chromosome X, Y and 18 (or 17) in group III. RESULTS: Blastomere biopsy was successful in 530 embryos and FISH efficiency was 92.3%. The proportions of transferable embryos in each group were 32.5+/-17.5%, 23.0+/-21.7% and 52.6+/-29.2% (mean +/- SD), respectively, showing higher normal rate in group III (group II vs. III, p<0.05). The numbers of transferred embryos in each group were 3.9+/-1.5, 1.9+/-1.1 and 3.1+/-1.4 (mean +/- SD), respectively. The clinical pregnancy rates per transfer was 0%, 30.0% and 20.0%, and it was significantly higher in group II (group I vs. group II, p<0.05). The overall pregnancy rate per transfer was 19.6% (10/51) and the spontaneous abortion rate was 20% (2/10) of which karyotypes were euploid. Nine healthy babies (one twin pregnancy) were born with normal karyotype confirmed on amniocentesis. CONCLUSION: Our data suggests that PGD-AS provides advantages in patients with RSA associated with aneuploidy or sex chromosome abnormality, decreasing abortion rate and increasing ongoing pregnancy rate. It is not likely to be beneficial in RIF group due to other detrimental factors involved in implantation.

OBJECTIVES: We aimed to investigate the clinical effect of low-dose intravenous immunoglobulin treatment in unexplained recurrent spontaneous aborters (RSA) with elevated peripheral CD56+ natural killer (NK) cell levels and to determine the pre-conceptional NK cell percentage predictive of subsequent successful pregnancy outcome. MATERIALS AND METHODS: Sixty four cases of unexplained recurrent miscarriage with elevated peripheral NK cells (>15%) were received low dose IVIg infusion at the dosage of 400 mg/Kg/month after confirmation of gestational sac and continued until 20 weeks. The patients were divided into two groups according to the pregnancy outcome: Group I was success of treatment defined as live birth at or after 25 gestational weeks and Group II was failure of treatment. The preconceptional levels of the peripheral blood NK cells were compared between two groups. RESULTS: Fifty-three pregnancies resulted in live births after 25 weeks and 11 resulted in abortion (Overall success rate of IVIG treatment was 82.8%). Preconceptional CD56+ NK cell percentage in group II (27.4+/-1.9%) was higher than those in group I (22.3+/-0.8%). By using ROC curve, optimal discrimination between success and failure of treatment was achieved with < or = 27% of preconceptional NK cell percentage. CONCLUSION: In RSA patients with elevated NK cells, we suggest that preconceptional peripheral blood CD56+ NK cell level could be a useful marker for predicting successful treatment outcome of low-dose IVIg infusion.

OBJECTIVE: The aim of present study was to evaluate the effectiveness of low-dose intravenous immunoglobulin (IVIg) therapy in women with recurrent spontaneous abortions (RSA) and elevated pre-conceptional peripheral blood CD56+Natural Killer (NK) cell percentage. STUDY DESIGN: Retrospective case control study. MATERIALS AND METHODS: Thirty three women with RSA and elevated pre-conceptional peripheral blood CD56+NK cell percentage who had received low-dose IVIg therapy (400 mg/kg per day, every 4 week, until 20 gestational weeks) were included in this study. Controls were nine women with RSA and elevated pre-conceptional peripheral blood CD56+ Natural Killer (NK) cell percentage who had not received IVIg therapy were included in this study. Medical records of study and control groups were retrospectively analyzed and we compared the successful pregnancy outcomes between two groups. Successful pregnancy outcome was defined as pregnancy ongoing beyond 25 gestational weeks. RESULTS: Age, number of previous abortions, pre-conceptional CD56+NK cell percentage and type of RSA were not statistically different between two groups. Otherwise, twenty-five women who received IVIg therapy (25/33, 75.8%) but, only three women who had not received (3/9, 33.3%) had a successful pregnancy outcome and the rate difference between two groups was statistically significant. CONCLUSION: Based on our study, low-dose IVIg therapy have a effective role in treatment of RSA patients with elevated pre-conceptional peripheral blood CD56+ Natural Killer (NK) cell percentage, but more larger scaled prospective study is needed for available of conclusive evidence.

OBJECTIVE: To determine whether characteristics of sperm motility obtained by computer-assisted sperm analysis (CASA) could predict pregnancy after intrauterine insemination (IUI) in couples with unexplained infertility. METHODS: Three hundred eighty-three cycles of intrauterine insemination with superovulation were retrospectively analyzed. Semen analysis was performed with CASA before and after swim-up and the parameters were compared between pregnant and non-pregnant women. RESULTS: The pregnancy rate per cycle was 14.1%. Pregnant and non-pregnant women were comparable in terms of age, infertility duration, the number of dominant follicles. While sperm concentration, motility, and parameters such as average path velocity (VAP) and percentage rapid (RAPID) before semen preparation were significantly different between the pregnancy and non-pregnancy groups, there were no differences in sperm parameters when comparing the two groups after preparation. Using a receiver operating characteristic curve to measure sensitivity and specificity, the optimal threshold value for the predictors of pregnancy was revealed to be a concentration of > or =111x10(6)/mL, a motility of > or =51.4%, and RAPID > or =30.1% before preparation for IUI. CONCLUSION: Sperm parameters including concentration, motility, and RAPID before sperm preparation could have predictive value for pregnancy outcome after intrauterine insemination with superovulation in couples with unexplained infertility, and would be helpful when counseling patients before they make the decision to proceed with IVF/ICSI-ET.

Background: Tea tree oil has antiviral, antimicrobial and antifungal effects and Mastic oil has antifungal and anticancer effects. For synergistic effects of oils, blending oil containing a mixture of two to three oils is recommended. This study aimed to determine the antibacterial effects of Tea tree oil, Mastic oil, and Blending oil containing the two oils in a mixture, to verify and suggest the potential use of these oils as a substance to prevent dental caries. Methods: Tea tree oil, Mastic oil, and Blending oil with a 1:1 blend of the two oils were diluted in liquid medium to 0% (negative control), 0.5%, 1.0%, and 2.0%. Streptococcus mutans was applied to each experimental group of the three diluted oils and after 8 h culture, the optical density (OD) was measured and the growth inhibition rate for S. mutans was estimated. Results: Tea tree oil had significantly low OD values across all concentrations (p<0.05) without significant variation among different concentrations (p>0.05). Mastic oil did not significantly vary in OD compared to the negative control across all concentrations (p>0.05) without significant variation among different concentrations (p>0.05). Blending oil, compared to the negative control, did not significantly vary in OD at 0.5% (p>0.05) but significant variation was found as the concentration increased (p<0.05). Additionally, for Tea tree oil and Mastic oil, the growth inhibition rate showed no significant variation according to concentration (p>0.05), whereas for Blending oil, the growth inhibition rate for S. mutans showed a significant difference at 1.0% (p<0.05) and at higher concentrations. Conclusion Blending oil containing a Tea tree oil and Mastic oil demonstrated a significant growth inhibition effect on S. mutans from the concentration of 1.0%, which suggested its potential use as an effective antibacterial agent for dental caries.

Peritoneal pregnancy is an implantation in the peritoneal cavity exclusive of tubal, ovarian, or intra-ligamentary implantations. This is a rare obstetric complication with high maternal mortality and even higher perinatal mortality, and secondary type was most common. Risk factors for peritoneal pregnancy are previous history of extrauterine pregnancy or tubal surgery pelvic post-inflammatory status or presence of an intra-uterine device. As it is a life-threatening condition, expectant management carries a risk of sudden life-threatening intra-abdominal bleeding and a generally poor fetal prognosis. So, when it is recognized, immediate termination of pregnancy is usually recommended. Early diagnosis of peritoneal pregnancy is difficult, but is important by their life threatening progress course to patients. Recently, we experienced primary peritoneal pregnancy which meets both the original and modified criteria. In this paper, we reported the case of early diagnosed and successfully treated peritoneal pregnancy despite of their diagnosis was incidentally.

OBJECTIVE: To evaluate correlations between serum anti-Mullerian hormone (AMH) levels, phenotypes of polycystic ovary syndrome (PCOS), obesity, and metabolic parameters in patients with PCOS. METHODS: A total of 175 patients with PCOS were diagnosed according to the Rotterdam Consensus were included. Exclusion criteria were age over 40, FSH>25 mIU/mL, and 17a-OHP>1.5 ng/mL. The Phenotypes of PCOS were divided into a severe form (oligo-anovulation, ANOV/hyperandrogenism/polycystic ovary morphology [PCOM]; n=59) and a mild form without HA (ANOV/PCOM, n=105). The serum AMH levels were classified into 3 groups (<5 vs. 5-10 vs. >10 ng/mL). Obesity was defined as body mass index (BMI) > or =25 kg/m2 (n=34). RESULTS: The mean age was 25.9+/-5.7 year and mean AMH level was 10.1+/-5.4 ng/mL. The BMI (kg/m2) was higher in group 1 (24.2+/-6.3) than in group 2 (21.9+/-4.3, p=0.046) or group 3 (21.6+/-3.3, p=0.019). There was no difference among the three groups in age, menstrual interval, antral follicle counts, androgens, or other metabolic parameters. The obesity group showed significantly lower AMH (7.7+/-3.9 ng/mL vs. 10.7+/-5.6 ng/mL), p=0.004) and low-density lipoprotein levels (93.1+/-21.2 mg/dL vs. 107.5+/-39.3 mg/dL, p=0.031), and showed higher total T (0.74+/-0.59 ng/mL vs. 0.47+/-0.36 ng/mL, p=0.001), free T (2.01+/-1.9 vs. 1.04+/-0.8 pg/mL, p=0.0001), and free androgen index (6.2+/-7.9 vs. 3.5+/-3.0, p=0.003). After controlling for age factors and BMI, the serum AMH levles did not show any significant correlations with other hormonal or metabolic parmeters. CONCLUSION: For PCOS patients under the age 40, serum AMH is not negatively correlated with age. High serum AMH levels can not predict the phenotype of PCOS and metabolic disturbances in PCOS patients in the non-obese group. Further study might be needed to define the relation more clearly.

OBJECTIVE: The aim of this study was to evaluate the influences of uterine septum and their elimination on the reproductive outcomes in women who have history of recurrent spontaneous abortion (RSA) and/or infertility. METHODS: The medical records of reproductive outcomes in patients who have had history of RSA and infertility who were diagnosed with uterine septum only by hysterosalpingogram (HSG) between January 2008 and December 2009 were retrospectively analyzed. The subjects who have had severe male factor, tubal factors, other uterine factors, endocrine abnormalities, peritoneal factors, and abnormal karyotyping among both partners were excluded. In 27 patients, confirmation of diagnosis by laparoscopy and elimination of uterine septum by trans-vaginal hysteroscopy was done. Seventeen patients were strongly suspected to uterine septum on HSG but tried to get pregnancy without any other procedure for evaluation and management of uterine anomaly. Age matched 42 patients who have history of RSA and/or infertility and diagnosed to normal HSG finding at same period were randomly selected as control. The medical records of reproductive outcomes were analyzed and compared between groups. RESULTS: The mean time of observation after diagnosis was 21.8 months (10 to 32). 55.6% (15/27) of patients in patients who received trans-vaginal hysteroscopic uterine septotomy were success to get pregnancies and was significantly higher than that of 17 patients who did not receive proper management (23.5%, 4/17, p<0.05). In control population, 40.5% (17/42) were success to pregnancies and the differences were not statistically significant compared to both two study groups. The live birth rate which was excluded pregnancy loss by abnormal fetal karyotyping and congenital anomaly were 75% (9/12) in treated septated uterus group and 84.6% (11/13) in control group each which have no statistically significant different. In patients with septated uterus who did not receive proper management showed lower delivery rate (50%, 2/4) than that of other groups but was not statistically significant. CONCLUSION: According to present data, women with a uterine septum have an increased chance of successful pregnancy with improved obstetric outcome after proper management of the uterine cavity. And these results were showed in patients with no regard to their reproductive history. But, in case of failed to receive proper management, uterine septum can affect not only pregnancy ongoing but successful pregnancy too.
