  • 목 적: 본 연구에서는 과배란 유도과정에서 나타나는 고농도의 에스트라디올이 임상 결과에 미치는 영향을 알아 보기 위해, 신선주기 배아이식과 동결-응해 배아이식의 임신율, 착상률과 분만율을 살펴보았다. 연구방법: 2003년부터 2005년까지 제일병원 아이소망센터를 내원한 불임 환자에서 신선주기 배아이식 1,565주기와 동결-융해 배아이식 670주기를 대상으로 조사하였다. 과배란 유도 시 hCG투여 당일 에스트라디올 농도에 따라 일차적으로 네 그룹으로 (A: 1,000$\sim$2,000 pg/ml, B: 2,000$\sim$3,000 pg/ml, C: 3,000$\sim$4,000 pg/ml, D: 4,000 pg/ml 이상) 구분하였으며, 이차적으로 환자의 나이에 따라 35세 미만인 군과 이상인 군에서 각각의 임신율, 착상률과 분만율을 통계적으로 분석하였다. 결 과: 전체적으로 신선주기 배아이식과 동결-융해 배아이식에서의 임신율, 착상률 및 분만율에는 유의한 차이가 없었다. 그리고 35세 미만인 환자들에서도 에스트라디올 농도에 따른 각 군에서의 신선주기와 동결-응해 배아이식의 임상결과에는 차이가 없었다. 그러나 35세 이상의 환자들에서는 에스트라디올 농도가 높은 Group-D에서 동결-융해 배아이식의 임신율이 신선주기 배아이식에서보다 유의하게 높게 나타났다 (51.3% vs 25.0%, p<0.05). 결 론: 결론적으로 나이가 많은 환자에서 과배란 유도에 의해 과도하게 높아진 고농도의 에스트라디올은 자궁내막의 착상 환경과 임상 결과에 좋지 않은 영향을 줄 수 있으므로, 이러한 경우 당 주기에 이식하는 신선주기 배아이식보다는 동결-융해 배아이식을 시도하는 것이 높은 임신율을 기대할 수 있는 방법으로 사료된다.

  • At infertility clinic, department of Obstetrics and Gynegology, Kyung Hee Medical Hospital, 80 patients who underwent IVF-ET from January to July, 1989 were evaluated for the prediction of endogenous LH Surge and its effects on outcome of controlled ovarian hyperstimulation (COH) were compared among LH Surge group without hCG given (N=18), with hCG given (N=5), and no-LH Surge group with hCG given (N=57). LH Surge were occurred in 23(28.7%) out of 80 patients studied. Serum E2 levels on Day-1, Day 0, Day+1, were no significant different among three groups. When basal serum LH/FSH ratio is above 1.0, the possibility of endogenous LH Surge is much higher (56.3% in LH Surge group without hCG given). Serum P4 levels on Day 0 were significantly increased in LH Surge group without hCG given. Cycles which serum P4 level is higher than l.0ng/ml were 70.6% of LH Surge group without hCG given. But there was no significant interrelationship between endogenous LH Surge and serum P4 rising rate as an efficient predictor of the occurrence of endogenous LH Surge in COH for IVF. There was no significant differences in number of follicles, follicular size on Day-1, Day 0, Day+1, and number of oocyte collected per cycle. The oocyte fertilization rate of No-LH surge group with hCG given was significantly higher than LH Surge group without hCG given. There was no significant difference in oocyte cleavage rate among three groups.

  • Objective: To investigate the association of FSH receptor (FSHR) polymorphism at position 680 with outcomes of controlled ovarian hyper-stimulation for IVF-ET in Korean women. Design: Genetic polymorphism analysis. Materials and Methods: The FSHR polymorphism was analyzed by PCR-RFLP in 172 ovulatory women below the age of 40 year. Patients with polycystic ovary syndrome, endometriosis, or previous history of ovarian surgery were excluded. Results: Genotype distribution was 41.9% for the Asn/Asn, 47.7% for the Asn/Ser, and 10.5% for the Ser/Ser FSHR genotype group. There was no difference in age of subjects and infertility diagnosis between genotype groups. When the patients were grouped according to their FSHR genotype, the basal levels of FSH (day 3) were significantly different among the three groups ($6.0{\pm}0.3\;IU/L$ (mean $\pm$ SEM), $5.8{\pm}0.3\;IU/L$, and $8.6{\pm}1.2\;IU/L$ for the Asn/Asn, Asn/Ser, and Ser/Ser groups, respectively, p=0.002). The Ser/Ser group showed a higher total doses of gonadotropins required to achieve ovulation induction, and a lower serum estradiol levels at the time of hCG administration compared with other two groups, but the differences were of no statistical significance. The numbers of oocytes retrieved were significantly different among the three groups ($8.6{\pm}0.8$, $9.9{\pm}0.6$, and $6.3{\pm}0.9$, for the Asn/Asn, Asn/Ser, and Ser/Ser groups, respectively, p=0.049). Clinical pregnancy rates were 42.4%, 25.9%, and 29.4% for the Asn/Asn, Asn/Ser, and Ser/Ser groups, respectively. Conclusion: Homozygous Ser/Ser genotype of FSHR polymorphism at position 680 was associated with decreased ovarian response to gonadotropin stimulation for IVF-ET.

  • The present study was designed to investigate if antithyroid antibodies (ATA) could affect the pregnancy outcome in euthyroid women undergoing in vitro fertilization and embryo transfer (IVF-ET). From October 1995 to September 1996, 28 euthyroid women with ATA who underwent IVF-ET were studied. Fifty-one euthyroid women without ATA who underwent IVF-ET served as control. Thyroid peroxidase antibody (TPOA) and thyroglobulin antibody (TGA) were assayed using radio ligand assay kits as ATA. All patients included in study and control groups had only tubal factor in infertility. Long protocol of gonadotropin-releasing hormone agonist (GnRH-a) was used for controlled ovarian hyperstimulation (COH) in all patients. There were no significant differences between study and control groups in patient characteristics such as age, infertility duration and hormonal profile. There were also no significant differences between two groups with respect to the clinical response to COH and IVF results such as number of retrieved oocytes, fertilization rate, number of embryos frozen and number of embryos transfered. There were no correlations between ATA (TPOA and TGA) titers and fertilization rate. The clinical pregnancy rate per cycle seemed to be lower in the study group than in the control group (26.3% vs 39.3%), but the difference was not statistically significant. The biochemical pregnancy rate per cycle and miscarriage rate were significantly higher in the study group at 18.4% (7/38) and 40.0% (4/10) compared with 5.6% (5/89) and 11.4% (4/35) in the control group. In the study group, both TPOA and TGA titers were significantly higher in the biochemical pregnancy group than in the clinical pregnancy group or non-pregnancy group. In 10 women with ATA who achieved pregnancy following IVF-ET, both TPOA and TGA titers were significantly higher in the miscarriage group than in the ongoing or delivery group. In conclusion, euthyroid women with ATA appear to represent a less favorable subset within other tubal factor patients when treated with IVF-ET.

  • 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.

  • Objectives: Recently, recombinant FSH (rFSH) has been manufactured using a Chinese hamster ovary cell line transfected with the gene encoding human FSH. Both rFSH and urinary gonadotropin (uFSH) could be used for controlled ovarian hyperstimulation (COH). However, uFSH implies a number of disadvantages, such as batch-to-batch inconsistency, no absolute source control, dependence on large amounts of urine, low specific activity, and low purity. The purpose of this study was to evaluate the efficacy of rFSH in human IVF-ET program. Materials and Methods: A total of 508 infertile women was enrolled in this study. They are classified into rFSH group (n=177) or uFSH group (n=331), and all of them were matched by age and cause of infertility in same period. The $Puregon^{(R)}$ (Organon, Holland) was used as rFSH, and the Metrodin-$HP^{(R)}$ (Serono, Switzeland) and $Humegon^{(R)}$ (Organon, Holland) was used as uFSH. We subdivided the patients into three age groups. The outcomes of IVF-ET program were analyzed using the statistical package for social sciences (SPSS). Results: There was no significant differences in the level of estradiol on hCG injection day, the numbers of retrieved oocytes, matured oocytes, fertilized oocytes, transferred embryos, frozen embryos between the two groups. The total dose (IU) of gonadotropin for COH was significantly lower in the rFSH group compared to uFSH group ($1339{\pm}5491.1$ vs $2527.8{\pm}1075.2$ IU, p<0.001). Clinical pregnancy rate per embryo transfer in the rFSH group showed increasing tendency, compared to the uFSH group, but there was no statistical significance (35.2% vs 29.3%). Our results demonstrated that the relative efficiency of rFSH compared with uFSH is higher in older patients. Conclusions: The ovarian stimulatory effect and clinical outcome of recombinant FSH was similar to that of the urinary gonadotropin. The IVF-ET cycles with significantly lower dose of gonadotropin in rFSH group showed comparable results. Therefore, we suggest that recombinant FSH is more potent and effective than urinary gonadotropin.

  • Objective: To evaluate the clinical outcomes and influencing factors of in vitro fertilization and embryo transfer (IVF-ET) in patients with failed pregnancy after microsurgical reversal of tubal sterilization. Materials and Methods : From January, 1997 to December, 2000, IVF-ET was performed in two groups; the study TR (tubal reanastomosis) group consisted of 147 cycles in 66 patients with failed microsurgical reversal of tubal sterilization, and the control group of 115 cycles in 67 patients with bilateral tubal occlusion (BTO). The two groups were evaluated and compared for clinical characteristics, clinical pregnancy rates, and factors influencing the outcomes of IVF-ET. Results: Compared with the control BTO group, age and the previous parity were significantly higher ($36.3{\pm}2.7$ vs. $33.6{\pm}2.0$ years, p<0.05; $1.6{\pm}0.7$ vs. $0.2{\pm}0.4$, p<0.05), and the clinical pregnancy rate per cycle was significantly lower (23.8% (35/147) vs. 29.3% (34/115), p<0.05) in the TR group. Difference in the clinical pregnancy rates was age-related, since there was no significant difference between the two groups, except for the previous parity ($1.6{\pm}0.7$ vs. $0.1{\pm}0.3$, p<0.05), when the patients aged 37 years or older were excluded. No difference was found in terms of the following: the proportion of controlled ovarian hyperstimulation (COH) cycles with GnRH agonist ultrashort protocol, the duration of COH, the dosage of gonadotropins used, and the numbers of oocytes retrieved and of embryos transferred, irrespective of age correction. Conclusions: The outcomes of IVF-ET following the failed microsurgical reversal of tubal sterilization depend upon patient age. The previous fertility of patients does not seem to be a factor of better IVF-ET prognosis.

  • Controlled ovarian hyperstimulation(COH) for in vitro fertilization and embryo transfer(IVFET) often results in the production of more embryos than can be efficaciously transferred at one time. However, embryo cryopreservation provides a mechanism by which additional embryos can be stored for later thawing and transfer. From November, 1990 to October, 1992, we completed 42 transfer cycles of cryopreserved pronucleus(PN) l-cell embryos using the fixed protocol of hormonal replacement therapy in a physiological manner regardless of individual ovarian function. Artificial endometrial stimulation was performed with only exogenous estradiol and progesterone(E-P) in 36 transfer cycles (Group I) and with gonadotropin-releasing hormone agonist(GnRHa) and exogenous estradiol and progesterone(GEEP) in 6 transfer cycles(Group II ). The results were as follows. 1. The Survival rate of total cryopreserved-thawed embryos was 64.9%(198/305): 64.9% (172/265) in Group I and 65.0% (26/40) in Group II. 2. Total 168 embryos were transferred with an average of 4.7 per ET in Group I and total 26 embryos were transferred with an average of 4.3 per ET in Group II. 3. The pregnancy rate(PR) per cryopreserved-thawed ET and the implantation rate was 33.3 %(14/42) and 6.7%(13/194), respectively. The PRs per cryopreserved-thawed ET were 30.6% (11/36) in Group I and 50.0% (3/6) in Group II without significant difference. 4. The take home baby rate was 11.1%(4/36) in Group I and 33.3% (2/6) in Group II.

  • It is well known that the clinical test for responsibility of accurate fertilization capacity in male partners is very important to diagnose and treat the infertility. However, it has been reported that the traditional semen analysis cannot accurately predict fertilization and pregnancy potential. The present study was performed to evaluate the acrosomal reaction to ionophore challenge (ARIC) test as a prognostic indicator for fertilization of sperm and oocyte in an in vitro fertilization and embryo transfer (IVF-ET) program. From March 1996 to Februry 1997, 30 couples undergoing IVF program were allocated to this study group. All female partners in the study group were 35 years old or less and their serum level of basal follicle stimulating hormone (FSH) and estradiol $(E_2)$ were normal. All the male partners have normal parameters of semen analysis. The ARIC tests were performed on the day of ovum pick up and in vitro insemination in all the male partners. The controlled ovarian hyperstimulation (COH) using luteal long protocol of gonadotropin releasing hormone (GnRH) agonist was used in all couples for IVF-ET. The acrosomal reaction with $10{\mu}l$ of 10% DMSO was induced spontaneously in $10.1{\pm}9.8%$, and acrosomal reaction with calcium ionophore A 23187 was induced in $27.4{\pm}18.1%$, and the ARIC value was $17.4{\pm}16.2%$. There were no significant correlation between the ARIC value and the fertilization rate ($r^2$=0.044, p=0.268). There were also no significant correlation between the ARIC value and the percentage of the grade I, II embryos ($r^2$=0.046, p=0.261). On the basis of above results, it was suggested that ARIC test might not be a useful prognostic indicator for fertilization in IVF-ET in male partners with normal parameters of conventional semen analysis. We guessed that IVF-ET could be performed to the patients primarily without universal appilcation of ARIC test to all male partenrs, and if fertilization failure occurs, the micro assisted fertilization (MAF) such as intracytoplsmic sperm injection (ICSI) might be used as an alternative mode of treatment with acceptable success rate.
