Objective: The aim of the present study was to investigate the relationship between ovarian follicle count and volume on ultrasonography and serum hormone levels including the levels of the anti-$M\ddot{u}llerian$ hormone (AMH) and gonadotropin in women with the polycystic ovary syndrome (PCOS). Methods: A total of 118 Korean women aged 18-35 years who were newly diagnosed with PCOS at a university hospital were included in this study. Serum LH, FSH, and AMH levels were measured in the early follicular phase, and the total antral follicle count (TFC) and the total ovarian volume (TOV) were assessed by ultrasonography. The correlations between serum hormonal parameters and ultrasonography characteristics in women with PCOS were evaluated using Pearson's correlation coefficients and a linear regression analysis. Results: Serum AMH levels were significantly correlated with serum LH levels and LH/FSH ratios, and TFC and TOV were significantly correlated with each other on ultrasonography. Serum AMH and LH levels and the LH/FSH ratio were significantly correlated with TFC. Statistically significant correlations between TOV and the LH level (r=0.208, p=0.024) and the LH/FSH ratio (r=0.237, p=0.010) were observed. However, the serum AMH level was not significantly correlated with the ovarian volume, and this result did not change after adjusting for age and body mass index. Conclusion: Serum AMH is not related to the ovarian volume in women with PCOS. My results suggest that serum LH level and the LH/FSH ratio may be more useful than the serum AMH level for representing the status of the ovarian volume in women with PCOS.

Objective: To assess the difference of baseline hormonal status and pathophysio logy, and confirm the risk factors for long term complication according to Body Mass Index in women with polycystic ovary syndrome. Materials and Methods: Serum level of LH, FSH, Estradiol, Prolactin, Testosterone, DHEA-S, fasting insulin were measured and 100 gm oral glucose tolerance test and endometrial biopsy were performed in total 75 chronic anovulation patients and 20 normal cycling infertility patients. 95 evaluated patients were divided into 3 groups including patients with chronic anovulation having BMI below 25, BMI beyond 25.1, normal cycling infertility patients, Group 1 (n=39), Group 2 (n=36), Group 3 (n=20), respectively. Statistical analysis was performed respect to relationship between BMI and measured hormone level, sum of glucose level during 100 gm OGTT, insulin resistance using t-test, ANOVA test, Post Hoc test, Mann-Whitney test. p<0.05 was considered as statistically significant. Results: Serum LH level and LH/FSH ratio was significantly higher in Group 1, compared than Group 2 or 3 (p<0.05), BMI and LH, LH/FSH ratio was negatively correlated (r=-0.351, r=-0.318). There was no significant difference according to BMI in FSH, testosterone, estradiol, prolactin, DHEA-S level. Fasting insulin and sum of glucose level during 100 gm OGTT were significantly higher in Group 2 compared than Group 1 or Group 3 (p<0.05), there was no significant difference between Group 1 and Group 3. Insulin resistance was more frequently identified in Group 2 compared than Group 1 (p=0.001). Conclusions: BMI and LH, LH/FSH ratio were negatively correlated, so clinical significance of LH, LH/FSH ratio in diagnosis of PCOS may be attenuated by increasing body weight. Overweight patients with chronic anovulation may be the risk group for developing insulin resistance, hyperinsulinemia, glucose intolerance, later type 2 DM. Hyperinsulinemia may operate mainly in overweight chronic anovulation patients in development of hyperandrogenism.

본 연구는 생식주기중 폐쇄여포액내에서 생물학적， 면역학적 특성을 나타내는 GTH 의 변화를 조사하고 steroid hormone과의 상관관계를 조사하며 국부조절인자로서 의 GTH의 역 활을 조사하고자 하였다. 가임기간중 215개의 여포와 IVF과정에서 185개의 여포를 얻어 여포액내 GTH의 생물학적 또는 면역학적 활성을 측정하였다. Bioactive LH(bLH)는 생쥐의 Leydig cell-testosterone production assay, bFSH는 흰쥐의 Sertoli cell aromatase assay로 측정 하였 다. Immunological GTH(iLH , iFSH) 는 MaiaClone RIA , Delfia kits를 사용하였다. 여포액내 iLH, iFSH , ihCG 는 hyperstimulation에 의해 형성된 여포의 크기와는 무관하였다. 또 hMG, huFSH 의 처리와도 상관성이 없었다. T의 농도가 높은 여포액내의 iFSH는 현저히 낮았으며 E, P 가 고농도인 여포의 ihCG 양은 현저히 낮았다. 과배란이 유도된 난소의 여포액내 iLH는 LH specific RIA로 측정시 3mIU/ml 이하이었다. 생식주기중 여포액내 bLH, bFSH는 배란기에 현저히 증가 하였다. 혈청내 GTH B/I ratio는 엘정한 반면 여포액내 LH，FSH의 생물학적， 면역학적 활성은 미수정란을 가지거나 폐쇄된 여포내의 활성보다 현저하게 높았다. 위의 결과로 보아 여포액내 생식소자극호르온은 면역학적활성보다 높은 생물학적 활성을 가지며， 생리적 현상의 지표가 된다고 추론된다. 또한 steroid, bGTH는 여포의 선택， 폐쇄를 구분하는 지표로 사용가능하며， 여포가 폐쇄될때 여포액내 B/I ratio가 현저히 낮아지는 것으로 보아 GTH의 활성이 감소되는 것으로 판단된다.

Purpose Precocious Puberty is defined as the development of secondary sexual characteristics in girls younger than 8 years, and boys 9 years. Cause premature closure of the epiphysis is a disease that eventually decreases the final adult height. In this study, we retrospectively analyzed to evaluate the diagnostic difference the GnRH (Gonado-tropin-releasing Hormone) stimulation test results with medical records of precocious puberty in girls. Materials and Methods From February 2015 to December 2015 it was enrolled in the girls 118 people who visited the Seoul National University Bundang Hospital, Pediatrics, Endocrinology Internal Medicine. True precocious puberty group (n=57), early puberty group (n=39), were divided into Premature thelarche (n=22) group. A Tanner stage, chronological age, bone age, height, body weight for each group was determined by examining the mean${\pm}$standard deviation. GnRH test result was compared LH (Basal, 30 min, 45 min, 60 min), FSH (Basal, 30 min, 60 min) for each group, Each group LH, FSH Peak value distribution, the mean${\pm}$standard deviation was calculated for the peak LH/LH basal ratio, peak LH/Peak FSH ratio. The significance probability (P-value) between the value of each third group was determined. Results The average height of the true precocious puberty group $131{\pm}14.85$, the mean weight was $28.80{\pm}4.93$, the average chronological age $7.1{\pm}0.81$, the mean bone age was $9.9{\pm}0.9$, The average height of early puberty group was $134{\pm}5.10$, the average weight $28.50{\pm}4.43$, the average chronological age $8.05{\pm}0.03$, the mean bone age was $10.0{\pm}0.62$, The average height of Premature thelarche $129{\pm}6,01$, the average weight was $28.65{\pm}5.98$, the average chronological age $7.02{\pm}0.58$, the mean bone age was $8.04{\pm}1.29$. There was no significant difference when compared to the height and weight. There was a significant difference between the groups in the chronologic age and bone age difference (P <0.0002) True precocious puberty group showed peak LH levels at 30'(82.5%), 45'(12.3%), 60'(5.3%), in Peak FSH 30'(8.8%), 60'(91.2%). Early Puberty group showed high values in Peak LH at 30'(79.5%), 45'(17.9%), 60'(2.6%), in peak FSH levels at 30'(7.7%), 60'(92.32%). In Premature thelarche Group it showed the Peak LH levels at 30'(30%), 45'(59%), 60'(9.09%), Peak FSH levels at 30'(0%) 60'(100%). When compared with the The Peak LH/basal LH ratio, True precocious puberty group was $19.09{\pm}17.15$, early puberty group was $15.23{\pm}10.88$, Premature thelarche group showed significant differences between the three groups as $4.93{\pm}4.36$.(P <0.0001) LH Peak/FSH Peak ratio, true precocious puberty group was $1.222{\pm}0.77$, early puberty group was $1.34{\pm}1.23$, Premature thelarche group showed significant differences between the three groups as $0.3{\pm}0.09$(P <0.0001) Conclusion In order to diagnose the true precocious puberty have a diagnostic value when the LH peak after GnRH stimulation is increased by more than two to three times compared to baseline or a predetermined level or more than 5~10 IU/L increases. GnRH Test is a test for a long time and the patient discomfort due to repeated blood sampling, but the hypothalamus-pituitary gland- gonad axis activity evaluate and is the most basic accurate test in the differential diagnosis of precocious puberty disorders.

Equine chorionic gonadotropin (eCG) consists of highly glycosylated noncovalently linked $\alpha$- and $\beta$-subunits and belongs to the glycoprotein hormone family that includes lutropin (LH), follitropin (FSH), and thyrotropin (FSH). eCG is a unique member of the gonadotropin family because it elicits response characteristics of both FSH and LH in other species than the hone. eCG is synthesized and secreted by trophoblastic cells of the endometial cups between 40 and 130 days of gestation. In the present study, mRNA expression ratio of eCG, eLH and eFSH $\alpha$- and $\beta$-subunints was investigated in the placenta and pituitary. mRNA was extracted from equine placenta on day 70 of gestation and from pituitary of male horse (27 month-old). When the expression of both subunit mRNAs of eCG in the equine placenta was compared by Northern blotting, the expression of the $\beta$ -subunit mRNA was relatively greater than that of the $\alpha$-subunit. And mRNA expression of $\alpha$-, LH $\beta$- and FSH $\beta$-subunits was analysed in the equine pituitary. An $\alpha$-subunit was revealed with a size of approximately 0.8 kb. FSH $\beta$-subunit mRNA also was detected out 1.8 kb. It is the same size of the FSH $\beta$ -subunit mRNA cloned. The intensity of $\alpha$-subunit mRNA was greater than that of the $\beta$-subunit suggesting that the expression of $\alpha$ -subunit was dominant in the equine anterior pituitary. Thus, the subunit mRNA levels seem to be independently regulated and their imbalance may account for differences in the quantities of $\alpha$- and $\beta$-subunits in the equine placenta and pituitary.

Purpose:The gonadotropin-releasing hormone (GnRH) test results of girls with precocious puberty were analyzed to determine whether this test can efficiently and clearly differentiate between central precocious puberty (CPP) and other disorders. Methods:Clinical and laboratory data of 54 girls with precocious pubertal signs were reviewed. Intravenous GnRH test was performed with blood samples obtained at 0, 30, 60, and 90 minutes. A peak luteinizing hormone (LH) level of ${\geq}5.0IU/L$ was indicative of CPP. Results:Of the 40 girls with CPP, 36 (90.0%), 3 (7.5%), and 1 (2.5%) showed peak LH levels at 30, 60, and 90 minutes, respectively. A percentage of girls whose peak LH ${\geq}5.0IU/L$ up to 30, 60, and 90 minutes was 92.5%, 100%, and 100%, respectively. The peak LH/follicle stimulating hormone (FSH) ratio of girls with CPP was 0.89${\pm}$0.49 and was <1 in 16 of the 40 girls (40.0%). Girls with peak LH/FSH ratio of >1.0 showed higher chronological age (CA) ($8.3{\pm}0.6$ vs. $7.7{\pm}1.0$ years, P=0.033), bone age (BA) ($10.9{\pm}0.8$ vs. $9.7{\pm}1.1$ years, P=0.001), and BA-CA difference ($2.6{\pm}0.7$ vs. $2.0{\pm}0.7$ years, P=0.009) than those of girls with peak LH/FSH ratio of ${\leq}1.0$. Higher percentage of girls with peak LH/FSH ratio of >1.0 showed advanced breast development (${\geq}TannerIII$) (93.7% vs. 41.7%, P=0.001). Conclusion:LH levels after 30 and 60 minutes of intravenous GnRH administration are the most useful for diagnosing CPP in girls.

Objectives: Polycystic ovary syndrome (PCOS) has the feature of excessive LH, hyperandrogenism and disturbance of folliculogenesis. Also, insulin, IGF-I and IGFBP-l are involved in the pathogenesis of PCOS. Various surgical and medical therapies have been used and the action mechanisms are related to the endocrine effect. Laparoscopic ovarian electrocautery or laser vaporization is effective in the restoration of ovulation and normal menstrual cycle with minimal invasive procedure especially in the patients resistant to medical therapy. Clomiphen citrate (CC) is used for the ovulation induction in pcas and the resistance is known to be related to insulin, IGF-I, IGFBP-l levels. This study was performed to evaluate the effect of the laparoscopic laser vaporization on the levels of LH, FSH, testosterone, IGF-I and IGFBP-l and on the ovarian response to clomiphen citrate in patients with CC-resistant PCOS. Materials and Methods: The fasting basal serum LH, FSH, testosterone, IGF-I and IGFBP-l level were measured in 10 PCOS patients with CC-resistance and 7 normal controls with regular menstrual cycle. In PCOS, after laparoscopic $CO_2$ laser vaporization, endocrine levels were measured in 1 week interval for 4 weeks and then compared with preoperative levels. Results: In PCOS group, mean serum LH/FSH ratio, testosterone, IGF-I levels were higher and IGFBP-l level was lower than control. LH/FSH ratio decreased from $2.51{\pm}0.67$ to $1.7{\pm}0.6$ (p<0.05) in 2 weeks, to $0.56{\pm}0.2$ (p<0.01) in 3 weeks and to $1.41{\pm}0.3$ (p<0.01) in 4 weeks after operation. Testosterone level decreased from $1.51{\pm}0.82ng/ml$ to $0.65{\pm}0.34ng/ml$ (p<0.05) in 2 weeks, to $0.56{\pm}0.67ng/ml $(p<0.01) in 3 weeks after operation. IGF-I level also decreased from $436{\pm}47.5{\mu}g/l$ to $187{\pm}38{\mu}g/l$ (p<0.0l) in 1 week, to $167{\pm}42{\mu}g/l$ (p<0.01) in 2 weeks, $179{\pm}55{\mu}g/l$ (p<0.01) in 3 weeks and to $120{\pm}43{\mu}g/l$ (p<0.01) in 4 weeks after operation. IGFBP-l level showed no significant change. In 8 of 10 PCOS patients, ovulation was induced with low dose clomiphen citrate. Conclusion: Laparoscopic $CO_2$ laser vaporization restores normal menstrual cycle and ovulation through endocrine effect of decreasing LH/FSH ratio, testosterone and IGF-I level and increases the response to CC. Therefore it is useful for restoration of normal menstruation and induction of ovulation in CC resistant PCOS patients.
