Purpose: The purpose of this study was to test a model for quality of life among infertile women. This model was based primarily on the concept of the Fertility Quality of Life by Boivin et al. (2011) and the Infertility Resilience Model by Rindenour (2009). Methods: Fifteen measurable variables were used to estimate quality of life. They included endogenous variables such as fertility quality of life and resilience, and exogenous variables such as infertility related stress, depression, marital adjustment, and family support. Data sets (n=203) used for analysis were collected in a general hospital which had, on average, 400 assisted reproductive technologies per month. Results: The assessment of the modified model indicated acceptable fit, with $x^2/d.f$=2.07, GFI=.90, AGFI=.89, NFI=.89, CFI=.91, RMSEA=.07. Depression, infertility related stress, marital adjustment, resilience, and family support had direct influences on quality of life. Conclusion: The results of this study should contribute to the development of nursing intervention programs to enhance quality of life using factors that affect fertiQol (fertility quality of life) of infertile women.

Objective: To evaluate whether diagnostic laparoscopy before transcervical fallopian tube catheterization (TFTC) would improve tubal recanalization rate and pregnancy rate in patients with bilateral proximal tubal blockage in hysterosalpingogram (HSG). Methods: The retrospective study was performed in those underwent TFTC from January 1998 to December 2001. A total of 50 patients with bilateral proximal tubal blockage in HSG were subjected to TFTC sequentially using repeated HSG (rHSG), selective salpingography (SS) followed by tubal catheterization (TFTC). Each procedure was terminated once patency had been achieved without proceding to the next technique. In Group A patients (n=35, 64 tubes), diagnostic laparoscopy was performed before TFTC was taken to exclude the tube combined with peritubal adhesion or distal tubal pathology. In Group B, patients (n=15, 26 tubes) were performed TFTC without diagnostic laparoscopy. Results: There were significant difference in clinical pregnancy rate (45.7% vs 15.4%, p=0.034) but no differences were found in recanalization rate (75.0% vs 73.1%) and complication rate (8.6% vs 13.3%). Although there is no signficant difference, more tubes were canalized by SS, which means tubal obstruction rather than occlusion, in Group A (25.0% vs 5.3%, p=0.069). Conclusion: Diagnostic laparoscopy would be effective in the selection of tube for the relatively inexpensive and less invasive TFTC or patients in need of assisted reproductive technologies. With the tubes without combined peritubal adhesion or distal tubal pathology, pregnancy rate was significantly increased.

Previous studies have indicated that immunological factor is responsible for the infertility. We have detected sperm antibodies in ZIFT patients which grouped as fertilization failure (A; n=18) and low fertilization rate (${\leq}50%$)(B; n=20). Patients, however, had normal oocytes and sperms. We collected serum from wives and semen from husbands and donors (fertile sperm), if it was needed. We examined class, binding patterns and amounts of antisperm antibodies(ASA) by direct and indirect immunobead binding assay. In group A, 11 husbands were ASA positive showing 62.2% and 61.1% binding with IgA and IgG, respectively, and two wives were ASA positive showing 70.0% and 71.0% binding with IgA and IgG, respectively. Binding sites were mainly at the head of sperms (84%). In group B, 8 husbands were ASA positive showing 37.5% and 40.0% binding with IgA and IgG, respectively, and two wives were ASA positive showing 41.3% and 42.0% binding with IgA and IgG, respectively. Binding sites were also mainly at the head of sperms (78%). For the treatment of ZIFT patients who had fertilization failure at the first trial, we used albumin fractionation method and dilution method with 30% fetal cord serum (FCS) to reduce the titer of ASA. We used partial zona dissection (P.Z.D.) method for wives who have antisperm antibodies in their serum. According to represented method, we could inhance the fertilization rate to 60.0% by albumin fractionation and 20.0% by P.Z.D., respectively. We concluded that the use of micromanipulation like P.Z.D. or the other sperm processing methods is required to increase a chance of fertilization. This result suggested that it should be a prerequisite to test antisperm antibodies prior to entering assisted reproductive technologies (ART) programs.

Purpose: The purpose of this study was to analyze anxiety and depression among infertile women at different time points during the first In Vitro Fertilization (IVF) or Intracytoplasmic Sperm Injection (ICSI) treatment through a systematic review and meta-analysis. Methods: Seven out of 3,011 studies were included for meta-analysis. To estimate the effect size, a meta-analysis of the studies was performed using the RevMan 5.3 program. We compared the measurement outcomes at three time points: before the start of treatment (T0), cancellation of treatment after pregnancy detection (T2), one to six months after treatment (T3). The effect size used was the standardized mean difference (SMD). Results: In comparing the different time points of the pregnant women from their cycle, significantly lower levels of depression were found at T2 than at T0. In non-pregnant women, anxiety at T2 and depression at T2 and T3 were significantly higher than those at T0. At T2 and T3, the non-pregnant women reported higher levels of anxiety and depression compared with the pregnant women. Conclusion: Anxiety and depression in infertile women undergoing the first IVF or ICSI are associated with the time points and pregnancy status after treatment. These findings suggest that attention should be paid to helping infertile women prepare for and cope with treatment and treatment failure.

수정에 의한 배 발생은 정자가 난자 내로 침입하여 정자와 난자의 반수체 핵질이 융합되고 이어 유사분열로 이어지는 과정에서 시작된다. 하지만 수정 및 초기 배 발생 동안 자웅 핵질과 난 세포질 구성 요소 상호간의 작용기전에 관해서는 명확히 알려져 있지 않은 부분이 많다. 수정보조기법인 세포질 내 정자 직접 주입법의 개발은 남성불임치료에 혁신적인 기술로 자리잡고 있을 뿐만 아니라 포유동물의 수정과정을 이해하는데 많은 도움을 주고 있다. 핵치환에 의한 복제동물 생산기법도 분화된 핵이 난 세포질 내에서 재 분화 (reprogramming)하여 발생하는 유일한 과정으로 세포질 구성요소들의 상호작용과 발생 조절 기능을 이해하는데 도움을 준다. 최근 몇 년간 돼지 난자 세포질에 정자 및 원형정자 직접주입, 세포질 이식, 세포질 융합 및 핵치환 한 후 난자의 발생과정을 간접 면역형광 분석법과 주사 전자현미경으로 조사하였다. 이러한 연구를 통해 체외수정, 세포질 이식 및 정자직접 주입법 등과 같은 임상치료기술 과 핵치환에 의한 복제동물생산 기법의 개선에 필요한 기초자료를 얻을 수 있었고, 포유동물 난자의 후생적 발생과정 (epigenesis)에 관해 공부할 수 있었다.

The aim of this study was to evaluate the post-thawed characteristics of leopard cat semen. In this experiment, semen was collected from two leopard cats (A and B) at wild animal center in Seoul Grand Park in Korea. After collection, the sperms were washed with D-PBS and diluted by the freezing medium (Irvine science, USA) and stored in liquid nitrogen. The post-thawed concentration was $357{\times}10^6sperms/ml$ for A and $97{\times}10^6sperms/ml$ for B. The viability of post-thawed sperm from A and B individual was 24.0% and 19.0%, respectively. Pre-freezing motility of A and B individual semen was 68.54% and 56.65. Leopard cat A had more normal sperm than that of B (69.5% vs. 54.5%). Acrosome integrity analysis detected live (14.5% vs. 9.0%), damage (39.0% vs. 44.0%) and dead (46.0% vs. 47.0%) in leopard cat A and B, respectively. The present results concluded that leopard cat semen can be collected successfully by electro-ejaculation method and cryopreserved successfullyfor future use in different assisted reproductive technologies. The cryopreservation protocol needs to be modified for increasing post-thawed viability of leopard cat spermatozoa.

Objectives: The purpose of this study was to analyze the current characteristics and prescriptions of outpatients with Polycystic Ovary Syndrome (PCOS). Methods: We searched medical records from January 1, 2017 to December 31, 2017 and found out 31 patients who first visited with PCOS. Results: The average age of PCOS patients was $26.48{\pm}5.15years$ old, average height was $162.16{\pm}5.56cm$, average weight was $55.27{\pm}9.34kg$, and average BMI was $21.01{\pm}3.48kg/m^2$ A total of 24 patients who had received western treatment for PCOS in the past, 13 people received oral contraceptions, 4 hormones, 2 metformin, one hormone and metformin, also 4 people were treated for assisted reproductive technologies due to infertility. There were only two patients who combined Korean and Western treatments. The most common menstrual-related symptoms of PCOS patients were oligomenorrhea (48.4%) and dysmenorrhea (22.6%). Other symptoms were the highest in the cold symptoms (54.8%), followed by infertility (9.7%). The average number of patients visiting the hospital was $6.26{\pm}7.2$, with 22 (71.0%) coming from 1 to 5. The average treatment period for patients was $10.1{\pm}10.8weeks$, with 41.9% the largest for 1 to 4 weeks. Acupuncture (93.5%), moxibustion (96.8%) herbmed (96.8%) was treated to most PCOS patients. The most commonly used herbal medicines were Ongyeong-tang (35.5%), Ijin-tang-gami (19.4%), Dodam-tang-gami (12.9%), and Jogyeongjongok-tang-gami (12.9%). Conclusions: These results could be helpful to treat PCOS patients in Korean gynecologic clinical fields.

Objective: If fertilization does not occur within a specific period, the quality of unfertilized oocytes in the oviduct (in vivo aging) or in culture (in vitro aging) will deteriorate over time. Icariin (ICA), found in all species of Epimedium herbs, has strong antioxidant activity, and is thought to exert anti-aging effects in vitro. We asked whether ICA protects oocytes against age-related changes in vitro. Methods: We analyzed the reactive oxygen species (ROS) levels and expression of antioxidant, maternal, and estrogen receptor genes, and along with spindle morphology, and the developmental competence and quality of embryos in the presence and absence of ICA. Results: Treatment with 5 μM ICA (ICA-5) led to a significant reduction in ROS activity, but increased mRNA expression of glutathione and antioxidant genes (superoxide dismutase 1 [SOD1], SOD2, peroxiredoxin 5, and nuclear factor erythroid 2-like 2), during aging in vitro. In addition, ICA-5 prevented defects in spindle formation and chromosomal alignment, and increased mRNA expression of cytoplasmic maturation factor genes (bone morphogenetic protein 15, cyclin B1, MOS proto-oncogene, serine/threonine kinase, and growth differentiation factor-9). It also prevented apoptosis, increased mRNA expression of antiapoptotic genes (BCL2-like 1 and baculoviral IAP repeat-containing 5), and reduced mRNA expression of pro-apoptotic genes (BCL2 antagonist/killer 1 and activation of caspase-3). Although the maturation and cleavage rates were similar in all groups, the total cell number per blastocyst and the percentage of apoptotic cells at the blastocyst stage were higher and lower, respectively, in the control and ICA-5 groups than in the aging group. Conclusion: ICA protects oocytes against damage during aging in vitro; therefore, it can be used to improve assisted reproductive technologies.
