The ethanol extract of the Crotalaria juncea seeds, which showed promising antispermatogenic and antiandrogenic activities in albino mice, was taken up further for the isolation of the active fractions present in it. Two fractions that were obtained from thin layer chromatography were subjected for testing to know their antispermatogenic and antiandrogenic activities. After preliminary trials the fraction I showed maximum antifertility activity at the dose level of 200 mg/kg body weight when administered orally to the rats for 50 days. The fraction I was found to affect spermatogenesis as well as the endocrine functions of the testis as indicated by gravimetric, histopathological and biochemical changes. Further this fraction has caused degenerative changes in the seminiferous tubules and Leydig cells of the testis. The accessory reproductive organs like epididymis, seminal vesicles, vas deferens, prostrate, Cowper's gland and Levator Ani muscle showed significant malfunction. Cauda epididymal sperm count and sperm motility were reduced significantly. The treatment has also resulted in increase in the cholesterol level and alkaline phosphatase activity, and decrease in protein, glycogen, sialic acid contents and acid phosphatase activity in testis. It is noteworthy that RIA studies have shown significant reduction in serum FSH, LH and testosterone. Scanning electron microscopic observations revealed abnormalities in sperm structure.

The present experiments were carried out to investigate the mode of cAMP regulation of cumulus expansion in pig. Intracellular level of cAMP in the cumulus cells was modulated by culturing porcine cumulus oocyte complexes (COC's) with forskolin, an adenylate cyclase stimulator and 3-isobutyl-1-methylxanthine (IBMX), a phosphodiesterase inhibitor. The role of calcium in the hormone induced cumulus expansion process was also studied. Forskolin in the medium stimulated cumulus expansion from the concentration of 0.01 $\mu$M and induced full expansion at l-10 $\mu$M In contrast, IBMX in the medium (20-180 $\mu$M) failed to induce the expansion. Verapamil, a calcium ion transport blocker, suppressed follicle stimulating hormone(FSH)-induced cumulus expansion in a dose dependent fashion (0.002-0. 2 mM) when the COC's were exposed to the drugs during culture period (32 hr). But verapamil did not interfere with the triggering action of FSH during early four hours of culture period. The data presented here showed that adenylate cyclase in the porcine cumulus cells may play a key role in the regulation of the intracellular cAMP level and calcium ion may be involved in the later period of cumulus expansion process.

Objectives: To determine whether the body weight, body mass index (BMI), and basal serum level of LH, FSH, testosterone (T), dehydroepiandrosterone sulfate (DHEA-S) are related to the ovarian response to clomiphene citrate (CC) in patients with polycystic ovarian syndrome (PCOS). Materials and Method: From January 1996 to June 1997, total 57 patients with PCOS were enrolled in the present study. Women who had other infertility factors were excluded from our study. The ovulation induction using CC was used in all patients. The patients were grouped into 50 mg group, 100 mg group, and 150 mg group according to their daily CC dose. The patients were also grouped to ovulatory and non-ovulatory group. The body weight, BMI, and basal serum level of LH, FSH, T, DHEA-S were measured in all patients on the 2nd or 3rd day of the menstrual cycle. Results were analysed with Student's t-test and Fisher's exact test. Results: The body weight and BMI of the nonovulating group were significantly higher than those of the ovulating group in all groups (50, 100, 150 mg of CC). However, there were no significant differences of the level of LH and FSH between ovulating and nonovulating groups in all CC groups (50, 100, 150 mg). The level of T of nonovulating group was significantly higher in 50 and 100 mg of CC groups, but not in 150 mg group. The level of DHEA-S of the non-ovulating group is significantly higher in 50 mg group, but not in 100 and 150 mg groups. Conclusion: The body weight and BMI could be useful predictors of ovarian response to CC in patients with PCOS, and basal T and DHEA-S also might be useful in cases of low-dose CC treatment.

Normal and abnormal follicular growth and steroidogenesis depend on gonadotropins as well as intraovarian peptides, which may mediate or potentiate gonadotropin action. Inhibin also affect follicular development and steroidogenesis and may play a role in dominant follicle selection and follicular atresia. Therefore, we studied the differences of serum inhibin, gonadotropin and androgen levels in the women with only the ultrasound findings and no disorder, and polycystic ovary (PCO) with ovulatory disturbance. We prospectively analysed forty-three women with PCO. The diagnosis of PCO was based on typical appearance of the ovaries on TVS. Twelve women with regular menstrual cycle and normal ovarian morphology were selected as control. Basal levels of inhibin, luteinizing hormone (LH), follicle stimulating hormone (FSH), estradiol $(E_2)$, testosterone (T), androstenedione (ADD), dehydroepiandrosterone-sulfate (DS), prolactin and TSH in serum were determined. There were significant differences in basal LH levels and LH/FSH ratio between the control and the women with PCO. The basal levels of inhibin and $E_2$ in the oligo-amenorrheic PCO (N=34) were significantly higher than those in the control. There was higher negative correlation between the inhibin and T levels in the oligo-amenorrheic PCO, but, not in the regular cycling PCO. Also, there was higher positive correlation between the LH and T levels in the oligo-amenorrheic PCO, but not in the regular cycling PCO. These data presume that the initial event of PCO is elevated pituitary LH secretion. Elevated levels of LH may down-regulate LH receptors on granulosa cells and also cause hypertrophy of the thecal layer. High level of androgen secreted by the hypertrophied thecal layer may stimulate inhibin secretion from granulosa cells and can be converted to estrogen by extraovarian tissues and could serve to augment pituitary sensitivity to GnRH with a resultant secretion of more LH than FSH. Inhibin may inhibit FSH action on granulosa cell in the PCO follicle, impairing follicular development and dominant follicle selection resulted in ovulatory disturbance.

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.

Recently the application of gonadotropin-releasing hormone (GnRH) agonist to superovulation in previous poor responders has resulted in the improved outcomes after in vitro fertilization (IVF) outcome. However, poor responders with poor estradiol $(E_2)$ rise or single dominant follicle are a particularly challenging group. Recent reports have also shown that patients with higher basal serum follicle stimulating hormone (FSH) level, result in poorer ovarian response and lower pregnancy rate. Analysis of the differences of superovulation outcomes according to the different protocols of GnRH agonist, long (L, n = 18) and short (S, n = 16) protocols, in patients with high basal FSH levels (>20mIU/ml) were undertaken at Seoul National University Hospital from June to October 1990. The administration of GnRH agonist was begun on day 21 of the cycle in long protocol, and on day 2 in short protocol. Ages of patients and husbands, basal FSH and luteinizing hormone (LH) levels and FSH/LH ratio did not differ significantly. Types and causes of infertility were evenly distributed. Whereas the duration of stimulation and the amounts of gonadotropins administered were significantly reduced in short protocol, the numbers of oocytes retrieved and cleaved, the cleavage rate and the number of embryos transferred were higher in long protocol without statistical signifieance. The pregnancy rate per ET was 16.7% (2/12) in short protocol, and 17.6% (3/17) in long protocol. These data suggest that both protocols result in the similar superovulation outcomes in patients with higher basal serum FSH levels.
