Purpose: The purpose of this study was to identify the effects of a Yoga-focused prenatal program on the stress, anxiety, self confidence and labor pain of pregnant women who had in vitro fertilization (IVF) treatment. Methods: A quasi experimental study with a non-equivalent control group pretest-posttest design was used. The data collection period and meditation program were between January 9 and August 31, 2009. Forty-six women who were pregnant following IVF, and were between 12-20 weeks gestation, participated in the study (23 experimental group, 23 control group). Data were analyzed using Chisquare test, Mann-Whitney U Test, ANCOVA, and Cronbach's alpha coefficients with the SPSS 12.0 for Windows Program. Results: Although the sample size was limited, women who participated in the program showed statistically significant improvements in stress, anxiety, labor pain, and labor confidence for women pregnant after IVF. Conclusion: The result indicate that this 12-week Yoga-focused educational program can be utilized for women pregnant following IVF to reduce their stress, anxiety, and labor pain, and to increase delivery confidence. It is suggested that the Yoga-focused educational program be offered to every pregnant woman.

Objectives: The aim of this study was to assess appropriate time to convert intramuscular progesterone support to oral administration for luteal phase support in in vitro fertilization (IVF). Methods: Seventy-six cycles of IVF in which fetal heart beat was identified after treatment were included. Patients underwent controlled ovarian hyperstimulation with GnRH agonist long protocol (n=7) or GnRH antagonist protocol (n=66). Cryopreserved embryo transfer was performed in three cycles. Luteal support was initiated by daily intramuscular injection of progesterone, and after confirmation of fetal heart beat, converted to oral micronized progesterone (Utrogestan, Laboratoires Besins International, France) 300 mg daily before or after 8 gestational weeks. The oral progesterone was continued for 11 weeks. Results: Overall clinical abortion rate was 3.9% (3/76) and mean time to conversion was $8^{+4}$ gestational weeks ($46{\pm}5.8$ days after oocytes retrieval). The abortion rate was 5.6% (1/17) and 3.4% (2/59) in patients with conversion before 7 weeks and after 8 weeks, respectively, which were not statistically significant (p=0.678). The miscarriages were occurred at $9^{+4}$ weeks, $11^{+3}$ weeks and $11^{+4}$ weeks. Conclusion: Sequential luteal support using intramuscular and oral progesterone yields a relatively low clinical abortion rate. If fetal heart beat confirmed, sequential regimen appears to be safe and convenient method to reduce patients' discomfort induced by multiple injections.

In oocyte retrieval, a vein anesthetic drug is commonly used for induction and maintenance of general anesthesia. Propofol and Thiopental sodium are frequently used for ultrasound-guided transvaginal oocyte retrieval. The present study aimed to assess the effects of Propofol and Thiopental on in vitro fertilization(IVF). Immature porcine oocytes were exposed to various concentrations ot Propofo1 and Thiopental sodium. The rates of oocyte maturation, fertilization and development were observed. The parthenogenetic effects of the anesthetics were also evaluated. The rate of oocyte maturation after exposure to high concentrations of the anesthetics for long time was significantly higher than that of the control. But the rate of fertilization after long-time exposure to the high concentration of the anesthetic drugs was significantly lower than that of the control. The results support that Propofo1 serves like other anesthetics described, as a parthenogenetic activator. Oocytes exposed to Thiopental sodium showed decreased rates of maturation and fertilization. These results suggest that usage of optimum concentration of anesthetic drug is important in increasing the rates of oocyte maturation, fertilization and development in IVF.

The purpose of this study was to examine obstetrical & gynecological health status and body composition for married female immigrants. The participants were 154 immigrant women living in Busan. Data were collected from July 2008 to July 2009 using a questionnaire and a bioelectrical impedance analysis tool (Inbody 720) for analysis of body composition. Most subjects were in the normal range for body composition, but some of those who answered the questionnaire had experienced some gynecological problems such as dysmenorrhea, or irregular menstruation. There was a significant difference in experiences with in vitro fertilization, pregnancy and abortion according to age and in premensturaion syndrome, as well as differences in regulation of menstruation during the past year, leukorrhea odor, experiences in in vitro fertilization, and delivery and breastfeeding according to nationality. There were significant differences in body mass index and waist-hip ratio according to age, as well as differences in percent body fat, body mass index and waist-hip ratio according to nationality. There were also significant differences in body mass index and waist-hip ratio according to period of stay in Korea. Procreative care protocols concerning married female immigrants' characteristics should be developed.

Controlled Ovarian hyperstimulation(COH) is generally used to obtain synchronous high quality oocytes in in vitro fertilization-embryo transfer(IVF-ET). Many investigators have studied the relationship between serum hormone levels and outcomes of IVF-ET because there is no accurate estimation method of oocyte quality. Early premature luteinization of follicles before oocyte retrieval is the most troublesome problem in COH for IVF-ET. Gonadotropin-releasing hormone agonists(GnRH-a) are used as adjuncts with gonadotropins for COH in patients undergoing in IVF. The possible benefits of GnRH-a pretreatment include improving oocyte quality, allowing a more synchronous cohort of follicles to be recruited, and preventing premature lueinization hormone surges. In COH of IVF cycles, we investigated whether an elevated progesterone(P4) level on the day of human chorionic gonadotropin(hCG) administration indicates premature luteinization and is associated with a lower fertilization rate. Many investigators have studied that the lower fertilization rates seen in patients with elevated P4 levels might result from an adverse effect of P4 on the oocytes. We hypothesizes that serum P4 levels around the day of hCG may be helpful prediction of out come in IVF-ET cycles. Success rates after COH of IVF-ET cycles are dependent upon many variable factors. Follicular factors including the number of follicles, follicular diameters and especially serum estradiol(E2) levels as an indirect measurement of follicular function and guality have been thought to influence the outcomes of IVF-ET. To assess whether serum P4 and E2 levels affect the fertilization and pregnancy rate, we reviewed the stimulation cycles of 113 patients (119 cycles) undergoing IVF-ET with short protocol with GnRH-a, from March 1993 to August 1994 retrospectively. The serum P4 and E2 levels were compared on the day of hCG in the pregnant group, 45 patients(47 cycles) and in the non-pregnant group, 68 patients (72 cycles) respectively. The serum E2 level in non-pregnant group was $1367{\pm}875.8$ pg/ml which was significantly lower than that of pregnant group, $1643{\pm}987.9$ pg/ml( p< 0.01 ). And the serum P4 level in non-pregnant group was $2.1{\pm}1.4$ ng/ml which was significantly higher than that of pregnant group, $1.0{\pm}0.7$ ng/ml( p< 0.001 ). The fertilization rate was $61.3{\pm}21.3%$ in pregnant group which was higher than that of non-pregnant group, $41.1{\pm}20.2%$ (p< 0.01). We suggest that the serum levels of P4 and E2 on the day of hCG administration are additional parameters that predict the outcomes of IVF-ET cycles.
