  • It was conducted the experiment, divided into three groups as normal, poor and polycystic ovary syndrome, to detect the change of protein patterns in follicular fluid on ovarian response following controlled ovarian hyperstimulation for human IVF outcome. In the normal group, it was confirmed reproducible 57 spots in the detected total 81 spots. Then 1 spot was not found in the other groups. In the poor responder group, it was found reproducible 53 spots in the detected total 98 spots. 6 spots were down-regulation and 7 spots were up-regulation comparable with normal group. There were not 5 spots in poor responder group comparable with other groups. In the polycystic ovary syndrome group, it was expressed reproducible 53 spots in the detected total 80 spots and 3 spots were just expressed in this group. However, 4 spots were not found in polycystic ovary syndrome. 9 spots were up-regulation comparable with normal group. Significant up and down-regulation spots among the each groups were identified. The results were a cytosolic carboxypeptidase, a signal-induced proliferation-associated protein 1, a ceruloplasmin, a keratin(type II cytoskeletal 1), a polypeptide N-acetylgalactosantinyltransferase 2, a serine/threonine-protein phosphatase 4 regulatory subunit 4. It was identified that 8 spots, 6 kinds of protein are corresponded with NCBInr database research, but 10 spots were failed in the identification. In conclusion, it has been confirmed change and expression of protein on the ovarian response following COH of human.

  • To investigate the effects of ovarian cysts on the controlled ovarian hyper-stimulation cycles, 16 patients with 16 paired cycles for IVF-ET were analyzed. These patients had taken both type of cycles, i.e., with cyst(cyst group) and without cyst(control group). Mean diameter of ovarian cysts in cyst group was 18.2mm. There were no significant differences in hormone levels in early follicular phase between two groups. No significant differences were found in total dosage of hMG(IU) administered during the ovarian stimulation $843.8{\pm}123.0$ vs $891.0{\pm}129.8$, serum estradiol level (pg/ml) on the day of hCG administration($1542.8{\pm}1100.6$ vs $1567.5{\pm}1193.0$), the number of aspirated follicles $10.0{\pm}3.4$ vs $11.2{\pm}4.3$ and oocytes $5.3{\pm}3.3$ vs $6.2{\pm}3.1$, the fertilization rate(51.2 % vs 57.2 %) and the cleavage rate(40.5 % vs 52.0 %). Serum estradiol terminal patterns during COH in one group tended to be repeated in the other group. In conclusion, this study suggests that small ovarian cysts do not adversely impact on the controlled ovarian hyperstimulation parameters in IVF - ET program and the presence of small ovarian cyst without concomitant high basal serum estradiol level is not an indication of the cancellation of the controlled ovarian hyperstimulation for IVF-ET.

  • Objectives: The aims of this study are 1) to determine if GAST is a better indicator in predicting ovarian response to COH compared with patient's age or basal FSH level and 2) to evaluate its role in detecting abnormal ovarian response. Design: Prospective study in 118 patients undergoing IVF-ET using GnRH-a short protocol during May-September 1995. Materials and Methods: After blood sampling for basal FSH and estradiol $(E_2)$ on cycle day two, 0.5ml (0.525mg) GnRH agonist ($Suprefact^{(r)}$, Hoechst) was injected subcutaneously. Serum $E_2$ was measured 24 hours later. Initial $E_2$ difference $({\Delta}E_2)$ was defined as the change in $E_2$ on day 3 over the baseline day 2 value. Sixteen patients with ovarian cyst or single ovary or incorrect blood collection time were excluded from the analysis. The patients were divided into three groups by ${\Delta}E_2$; group A (n=30):${\Delta}E_2$<40 pg/ml, group B (n=52): 40 pg/ml${\leq}{\Delta}E_2$<100 pg/ml, group C (n=20): ${\Delta}E_2{\leq}100$ pg/ml. COH was done by GnRH agonist/HMG/hCG and IVF-ET was followed. Ratio of $E_2$ on day of hCG injection over the number of ampules of gonadotropins used ($E_2hCGday$/Amp) was regarded as ovarian responsiveness. Poor ovarian response and overstimulation were defined as $E_2$ hCGday less than 600 pg/ml and greater than 5000 pg/ml, respectively. Results: Mean age $({\pm}SEM)$ in group A, B and C were $33.7{\pm}0.8^*,\;31.5{\pm}0.6\;and\;30.6{\pm}0.5^*$, respectively ($^*$: p<0.05). Mean basal FSH level of group $A(11.1{\pm}1.1mlU/ml)$ was significantly higher than those of $B(7.4{\pm}0.2mIU/ml)$ and C $(6.8{\pm}0.4mIU/ml)$ (p<0.001). Mean $E_2hCGday$ of group A was significantly lower than those of group B or C, i.e., $1402.1{\pm}187.7pg/ml,\;3153.2{\pm}240.0pg/ml,\;4078.8{\pm}306.4pg/ml$ respectively (p<0.0001). The number of ampules of gonadotropins used in group A was significantly greater than those in group B or C: $38.6{\pm}2.3,\;24.2{\pm}1.1\;and\;18.5{\pm}1.0$ (p<0.0001). The number of oocytes retrieved in group A was significantly smaller than those in group B or C: $6.4{\pm}1.1,\;15.5{\pm}1.1\;and\;18.6{\pm}1.6$, respectively (p<0.0001). By stepwise multiple regression, only ${\Delta}E_2$ showed a significant correlation (r=0.68, p<0.0001) with $E_2HCGday$/Amp, while age or basal FSH level were not significant. Likewise, only ${\Delta}E_2$ correlated significantly with the number of oocytes retrieved (r=0.57, p<0.001). All four patients whose COH was canceled due to poor ovarian response belonged to group A only (Fisher's exact test, p<0.01). Whereas none of 30 patients in group A (0%) had overstimulation, 14 patients among 72 patients (19.4%) in group B and C had overstimulation (Fisher's exact test, p<0.01). Conclusions: These data suggest that initial $E_2$ difference after GAST may be a better prognostic indicator of ovarian response to COH than age or basal FSH level. Since initial $E_2$ difference demonstrates significant association with abnormal ovarian response such as poor ovarian response necessitating cycle cancellation or overstimulation, GAST may be helpful in monitoring and consultation of patients during COH in IVF-ET cycle.

  • Objective: To evaluate if there is any correlation between the growth rate of dominant follicles and clinical characteristics or outcome variables in women undergoing controlled ovarian hyperstimulation (COH). Methods: This study was performed in 313 in vitro fertilization (IVF) cycles. Follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) were measured on day 3 of menstrual cycle, and serial ultrasonographic measurement of the diameter of growing follicles was performed. The growth rates of dominant follicles calculated by diameter difference divided by days were correlated with clinical characteristics and outcome variables. Results: There was no significant difference in the growth rate of the dominant follicles between gonadotropin releasing hormone (GnRH) agonist and antagonist cycles. No significant correlation was found between the growth rates and evaluated factors such as age, body mass index, LH, FSH, $E_2$, retrieved oocytes and fertilization rate. Conclusion: The Growth rate of dominant follicles seems to show an independent feature of basal characteristics and ovarian response.

  • Objective: To evaluate the ability of serum anti-M$\ddot{u}$llerian hormone (AMH), FSH, and age to clinically predict ovarian response to controlled ovarian hyperstimulation (COH) in IVF patients with endometriosis. Methods: We evaluated 91 COH cycles, including 43 cycles with endometriosis (group I) and 48 cycles with male factor infertility (group II) from January to December, 2010. Patients were classified into study groups based on their surgical history of endometriosis-group Ia (without surgical history, n=16), group Ib (with a surgical history, n=27). Results: The mean age was not significantly different between group I and group II. However, AMH and FSH were significantly different between group I and group II ($1.9{\pm}1.9$ ng/mL vs. $4.1{\pm}2.9$ ng/mL, $p$ <0.01; $13.1{\pm}7.2$ mIU/mL vs. $8.6{\pm}3.3$ mIU/mL, $p$ <0.01). Furthermore, the number of retrieved oocytes and the number of matured oocytes were significantly lower in group I than in group II. In group II, AMH and FSH as well as age were significant predictors of retrieved oocytes on univariate analysis. Only the serum AMH level was a significant predictor of poor ovarian response in women with endometriosis. Conclusion: Serum AMH may be a better predictor of the ovarian response of COH in patients with endometriosis than basal FSH or age. AMH level can be considered a useful clinical predictor of poor ovarian response in endometriosis patients.

  • Ovarian hyperstimulation syndrome(OHSS) is one of the well-known complication of controlled ovarian hyperstimulation(COH). Though there have been numerous measures to prevent the occurrence of OHS, it has not been completely preventable until now. The fluid shift from the intravascular space to the third space is due to decreased oncotic pressure of the serum. The objective of this study was to evaluate if IV administration of 20% albumin in those patients with OHSS risk can make prevention of severe OHSS. We retrospectively analysed 70 patients undergoing IVF-ET who had serum peak estradiol($E_2$) level of >2,500 pg/ml and/or the number of oocytes retrieved over 20. The treatment group(n=39) received albumin while the control group(n=31) did not. After 40 grams of human albumin diluted in 1,000 ml of 0.9% sodium chloride solution, the treatment group received half of the fluid during oocyte retrieval, the remainder in the recovery suite. The results were as follows; There were significant differences in the levels of serum peak $E_2$ and number of oocytes retrieved between the two groups(p<0.05). However, there were no significant differences in the incidence of OHSS and pregnancy rate or multifetal pregnancy rate. In conclusion, administration of albumin to OHSS risk patients did not reduce the rate of OHSS in IVF-ET. However, if we consider the fact that there were differences in the level of peak serum $E_2$ and oocyte numbers, further prospective study may be needed.

  • Some infertile patients who need IVF-ET for conception have small ovarian cysts diagnosed in pelvic ultrasonography. It is well known that it is impossible or very difficult to perform controlled ovarian hyperstimulation(COH) for such patients because of the poor ovarian response or the possibility of ovarian hyperstimulation syndrome(OHSS). To remove or to decrease the size of ovarian cysts, estrogen and progesterone (E-P) therapy with oral contraceptives for 2 cycles and transvaginal aspiration of ovarian cysts using transvaginal ultrasonography were performed in 36 IVF-cancelled infertile patients with ovarian cysts from February to October, 1988 at Seoul National University Hospital. Thirty-nine ovarian cysts($32.8{\pm}9.6$mm in mean diameter) were treated with E-P therapy, and their size decreased to $28.2{\pm}11.0mm$ after 1 cycle and significantly to $24.8{\pm}14.7mm$ after 2 cycles. After E-P therapy for 2 cycles, 7(17.9%) ovarian cysts disappeared in ultrasonography, 9(23.1%) decreased in size significantly, 18(46.2%) had no change in size and 5(12.8%) increased in size. Thirty-two ovarian cysts($30.2{\pm}9.7mm$) in 30 patients were aspirated transvaginally, and there was no significant decrease in size after follow-up transvaginal ultrasonography($27.8{\pm}12.5mm$). After transvaginal aspiration, 3(9.4%) ovarian cysts disappeared and 28(87.5%) had no change in size. The mean amount of the transvaginally aspirated cystic fluids was $19.6{\pm}13.2ml$, and there was no malignant cells in aspiration cytology. Four endometrioid cysts, one dermoid cyst and one mucinous cyst could be diagnosed in consideration of the findings of transvaginal ultrasonography and the characteristics and cytology of aspirated fluids. Therefore E-P therapy and transvaginal aspiration of ovarian cysts had made it possible to restart IVF program earlier in the IVF-cancelled patients with ovarian cysts.

  • To investigate the factors that affect the fertilization and cleavage rates of mature oocytes, 44 patients undergoing controlled ovarian hyperstimulation(COH) with FSH/hMG/hCG regimen for IVF - ET were analyzed. During follicular phase, serum LH levels were measured by radioimmunoassay and bioassay. Based on the mean follicular immunoactive LH(i-LH) and bioactive LH(b-LH) levels, patients were divided into 3 groups, respectively. There were no significant differences in basal serum FSH levels on menstrual cycle day 3, serum estradiol($E_2$) and progesterone ($P_4$) levels on the day of hCG administration, and the numbers of follicles aspirated and oocytes retrieved among groups. In relation to the mean follicular i-LH levels, the fertilization and cleavage rates of mature oocytes did not show a significant difference among groups. However, in groups with higher mean follicular b-LH levels, the fertilization and cleavage rates were reduced significantly. During late follicular phase, day-to-day variance in b-LH levels was not significant, but there was a significant difference among groups. There was no significant correlation between serum P. and b-LH levels. These data suggest that the fertilization and cleavage rates of mature oocytes are adversely affected by the raised mean follicular b-LH levels, and monitoring of serum b-LH levels is more useful in COH when compared with i-LH. It appears that the reduced rates are not due to the attenuated endogenous LH surge.

  • Objective: The purposes of this study were to determine the distribution of follicle-stimulating hormone receptor (FSHR) genotypes in infertile Korean women and to evaluate the relationship between FSHR genotypes and clinical outcomes of IVF-ET cycles. Methods: Genomic DNA was extracted from peripheral blood in 1, 020 of infertile Korean women. Genotypes of FSHR at Thr307Ala (T/A) and Asn680Ser (N/S) were screened by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis. Clinical outcomes related to the genotypes of FSHR were evaluated in IVF-ET cycles (n=302) with controlled ovarian hyperstimulation (COH) of infertile women under 40 years old. Results: In a population of 1, 020 infertile Korean women, the frequency of TT/NN, TA/NS and AA/SS for the major variant Thr307Ala and Asn680Ser was 44.80%, 41.96% and 10.49%, respectively. There was no significant difference in characteristics of ovarian response and clinical pregnancy rate among the major genotypes of FSHR in IVF-ET cycles with COH. However, implantation rate of AA/SS patients was significantly higher than that of TT/NN patients (24.5% vs 15.7%, p<0.05). Conclusion: This study showed that FSHR genotype was not directly associated with ovarian response in IVF-ET cycles with COH. The relationship between clinical outcomes and FSHR genotypes of patients should be substantiated by further studies.
