One of the most important complications in assisted reproductive technology (ART) is multiple pregnancy, which is associated with an increased risk of maternal and perinatal complications. There have been several attempts to achieve the highest pregnancy rates while minimizing multiple pregnancy rates in in vitro fertilization and embryo transfer (IVF-ET). One approach for this purpose is extended embryo culture and transfer of fewer (one or two) blastocysts. However, there are emerging concerns about the increase of the risk for embryo splitting and subsequent monozygotic multiple pregnancy with this approach. Recently, there have been several reports on the possible increased risk of monozygotic twinning after extended embryo culture and blastocyst transfer. We have experienced a case of two sets of monozygotic twins after intracytoplasmic sperm injection (ICSI) and transfer of two blastocysts. We report the first case of pregnancy of monozygotic twins after blastocysts transfer with a brief review of literature in Korea.

Heavy menstrual bleeding (HMB) is a common problem in primary care clinic of gynecology. HMB could cause adverse effect on the quality of life of many women. This guideline will provide evidence based information concerning diagnosis and management of HMB. Constructive dialogue should allow patients to be able to trust the advice given by their practitioner as they will be confident that they have and will be able to use it to inform this decision-making process. This guideline has been developed with the aim of providing guidance on HMB. The effectiveness of the various treatments as well as their risks and benefits are discussed in relation to their use in the treatment of HMB. We wish the information contained in this guideline will help clinicians reach a reasonable and beneficial decision with the latest information.

Authors designed a computer-based article data management system using a 16 bit IBM personal computer and dBASE IV program and applied it to the management of article data of the Korean Journal of Thoracic and Cardiovascular Surgery. In this system, authors developed a coding system for systemic classification of form and subject of articles and this coding system made the storage and inquiry of data easy and convenient. Using the coding system in this article management system, total 1476 sheets of articles in the Korean Journal of Thoracic and Cardiovascular Surgery were analyzed and briefly described according to their forms and subjects. If this article data management system including the coding system is applied to other Journals related to the department of thoracic and cardiovascular surgery, we can utilize them easily and conveniently for the save of time and effort in the data inquiry or article preparation.

Objective: To investigate the effects of female age on in vitro maturation and fertilization of immature oocytes from controlled ovarian hyperstimulation (COH) in human IVF-ET program. Method: A total of 96 immature oocytes (GV & metaphase I) obtained from 40 cycles of IVF-ET (29 patients). The mean age of female patients was $31.8{\pm}3.1years$. Ovulation was triggered by urinary or recombinant hCG. Immature oocytes were cultured with YS medium containing 30% of patients' human follicular fluids, LH (1 IU/mL), FSH (1 IU/mL) and EGF (10 ng/mL), and then matured oocytes were fertilized by ICSI. In vitro maturation and fertilization of immature oocytes were analyzed according to age of female (< 34 or ${\geq}34years$). Results: The maturation rate was similar between two groups (68% vs 64%). The fertilization rate of in?vitro-matured oocytes was higher in patients < 34 years old, but there was no statistical significance (64% vs 50%, p=0.347). The fertilization rate of in-vitro-matured oocytes was significantly lower compared with those of in-vivo-matured oocytes in both age groups (64% vs 79%, p=0.035, 50% vs 86%, p=0.007). Conclusion: In older female group, fertilization rate of in-vitro-matured oocytes seems to be decreased. Further investigations should be warranted to increase fertilization potential of in-vitro-matured oocytes.

목 적: 보조생식술에서의 정자처리법으로서 인간 난포액을 이용한 swim-down 방법의 유용성을 확인해 보고자 하였다. 연구방법: 분당서울대학교병원 산부인과에서 불임평가 목적으로 정액검사를 시행할 때 정자무력증 (asthenozoospermia, sperm motility < 50%)을 보이는 12명의 남성을 대상으로 하였다. 이들에서 검사 후 남은 정액을 100% 인간 난포액을 이용한 swim-down법과 SpermGrad를 이용한 밀도차 분리법을 적용하여 각각 처리하고 컴퓨터 정액분석기를 이용하여 정액검사를 시행하였다. 결 과: 두 군 모두에서 운동성과 빠른 운동성 정자의 비율, VCL (curvilinear velocity), ALH (amplitude of lateral head displacement)치 및 과활동성 정자의 비율이 통계적으로 유의하게 상승하였고 LIN (mean linearity)치는 유의하게 감소하였다. 100% 인간 난포액을 이용한 swim-down법에서 정자의 운동성이 SpermGrad를 이용한 밀도차분리법에 비하여 유의하게 높게 나타났으며 ($81.2{\pm}4.7$ vs. $67.6{\pm}2.3$, p=0.02), 다른 변수들은 두 군에서 차이를 보이지 않았다. 결 론: 100% 인간 난포액을 이용한 swim-down법은 정자무력증을 보이는 경우 유용한 정자 처리법으로 사료된다. Objective: We tested the usefulness of swim-down technique using human follicular fluid (hFF) in sperm preparation. Methods: Semen samples were obtained from twelve male partners showing asthenozoospermia (sperm motility < 50%) at the time of routine andrologic evaluation in Seoul National University Bundang Hospital. After dividing into two aliquots, each samples were processed either by swim-down using 100% hFF or density gradient using SpermGrad. Sperm quality was assessed by computer-assisted semen analyzer (CASA). Results: Motility, Rapid motility, VCL (curvilinear velocity), ALH (amplitude of lateral head displacement), and hyperactivated sperms were significantly increased, and LIN (mean linearity) was decreased significantly after sperm preparation in both groups. Motility was significantly higher after swim-down using 100% hFF when compared with density gradient using SpermGrad ($81.2{\pm}4.7$ vs. $67.6{\pm}2.3$, p=0.02) The other parameters assessed by CASA were not different between the two methods. Conclusion: Swim-down method with 100% hFF may be a useful method in preparation of sperm from asthenozoospermia.
