Objectives: The purpose of this study is to investigate the clinical significance of age and basal serum FSH in predicting the outcomes of in vitro fertilization (IVF) in patients with poor-ovarian response. Methods: From January 2000 to December 2004, 85 second IVF cycles of 85 poor-ovarian response patients under the age of 42 with a back-ground of the first IVF cycles at our infertility center and 5 or less oocytes were retrieved and their basal serum FSH levels of 15$\sim$25 mIU/ml were enrolled in this study. Exclusion criteria were patients with a male factor for the etiology of infertility and undergoing genetic diagnosis of embryo such as PGD. Flare-up protocol was used for ovarian stimulation in all cases. Results: When we stratified the study groups by patient's age, the younger age group (age<35, n=35) showed significantly higher implantation rate (19.0% versus 4.0%, p<0.05) and higher ongoing pregnancy rate (100% versus 14.3%, p<0.05) than the older age group (age$\geq$35, n=50). And then, when we stratified the study populations by basal serum FSH level, the lower FSH group (basal serum FSH<20 mIU/ml, n=58) showed significantly higher number of retrieved oocytes (4.6$\pm$0.7 versus 2.2$\pm$0.5, p<0.05) and lower cancellation rate (19.0% versus 55.6%, p<0.05) than higher FSH group (basal serum FSH$\geq$20 mIU/ml, n=27). Conclusions: In conclusion, it was suggested that the patient's age could predict the IVF outcomes in respect to its potency of pregnancy and ongoing pregnancy. Serum basal FSH levels could predict more accurately the ovarian response of cycle, but not clinical outcomes.

The experiment was conducted to study the effect of GnRH administration at induced estrus on pituitary and ovarian response in buffalo heifers. Eight Murrah river buffaloes of 12 to 13 months of age were treated with $PGF_{{2}{\alpha}}$ and eCG combination. GnRH (Fertagyl) 200 ug was injected (iv) at estrus in four heifers (treated group) while saline (2 ml, iv) was injected in remaining four heifers (control group). Blood was collected through jugular catheter to estimate plasma FSH, LH and estradiol level. The pretreatment plasma FSH, LH and estradiol values ranged from $8.46{\pm}1.97ng/ml$ to $12.31{\pm}1.30ng/ml$, $0.87{\pm}0.21ng/ml$ to $1.19{\pm}0.29ng/ml$ and $19.09{\pm}2.38pg/ml$ to $20.24{\pm}1.00pg/ml$ respectively. The plasma estradiol concentration elevated significantly (p<0.05) within 24 hr after eCG administration and reached its peak levels of $154.09{\pm}17.28pg/ml$ and $181.95{\pm}31.82pg/ml$ at estrus in respectively treatment and control groups. The plasma FSH and LH concentrations did not increase during follicular development after eCG administration while initial significant (p<0.05) increases in both plasma FSH and LH concentrations occured within 5 and 10 min, reaching peak levels of respectively $110.06{\pm}23.56ng/ml$ and $13.15{\pm}3.13ng/ml$ within 90 min after GnRH injection was detected. A sharp and significant decline in plasma estradiol concentration ($59.27{\pm}8.78pg/ml$) associated with synchronized ovulation within 24 hours after GnRH injection was recorded. The observation suggest that the hypophysis of prepubertal buffaloes treated with eCG have gonadotrophins awaiting the releasing factor to evoke release of gonadotrophin during the follicular phase to induce synchronized ovulation.

Objective: Pituitary adenomas are common neurological lesions believed to account for 10% to 15% of all primary brain tumors. There can be diagnostic confusion due to discordance of the preoperative endocrine and the postoperative immunohistochemical diagnosis. In this study, the rate of discordance between preoperative and postoperative findings and their clinical implications were investigated. Methods: From March 2005 to March 2006, 26 patients who underwent surgery for a pituitary adenoma were enrolled in this study. The preoperative pituitary hormone level and postoperative immunohistochemical results were compared and analyzed. Results: The median age of the patients was 38 years [range 15-66 years]. The male to female ratio was 8 to 18. The endocrine evaluation showed 16 hormonally-active and 10 hormonally-inactive adenomas. The immunohistochemical findings showed : 13 prolactin-positive, 1 GH-positive, 1 FSH-positive, 8 pleurihormone-positive and 3 stain-negative adenomas. The percentage of discordance observed between the preoperative endocrine and postoperative immunohistochemical diagnosis was 54%. Nine of 10 endocrine non-functioning adenomas showed : 3 PRL positive, 1 GH positive, 2 PRL+GH positive, 1 TSH+FSH positive, 1 FSH+ACTH+PRL positive and 1 FSH+LH+PRL positive adenomas by immunohistochemistry. Three endocrine PRL+GH secreting adenomas showed 2 PRL positive and 1 FSH+GH positive by immunohistochemistry. One endocrine PRL secreting and 1 GH secreting adenoma showed 1 PRL+ TSH positive and 1 GH+PRL positive by immunohistochemistry, respectively. The diagnosis of the other 12 pituitary adenomas showed concordance. Conclusion : The results of this study showed 54% discordance rate between the preoperative endocrine and postoperative immunohistochemical diagnosis for pituitary adenomas.

The effect of Cervi Cornu Parvum aqua-acupuncture on serum levels of sex hormone was investigated in ovariectomized rats. Water extract of Cervi Cornu Parvum was daily injected for 30 days at points in rats corresponding to bilateral Taixi (Ki. 3) points of human and non-point at root of tail after ovariectomy, respectively. Serum levels of estradiol, testosterone, progesterone, LH and FSH were measured at 2 and 4 weeks after aqua-acupuncture treatment, respectively. Compared with ovariectomized rats, significant increase of estradiol and progesterone and significant decrease of FSH and LH were elicited at 2 and 4 weeks after aqua-acupuncture treatment. Aqua-acupuncture treatment at non-point did not produce any remarkable effect. These findings suggest aqua-acupuncture may restore dysfunction of hypothalamic-pituitary-ovarian axis, associated with a significant increase of serum estradiol level in ovariectomized rats.

Ethane 1,2-dimethane sulfonate(EDS), a toxin which specifically kills Leydig cells(LC), has been widely used to prepare the reversible testosterone(T) depletion rat model. In the present study, we monitored the gene expression profiles of pituitary gonadotropins, LH and FSH, up to 7 weeks after EDS injection. Adult male Sprague-Dawley rats($300{\sim}350\;g$ B.W.) were injected with a single dose of EDS(75 mg/kg i.p.) and sacrificed on weeks 0, 1, 2, 3, 4, 5, 6 and 7. Total RNAs were purified from each pituitary, and the message levels of common alpha subunit($C{\alpha}$) of pituitary glycoprotein hormones, LH beta subunit($LH{\beta}$), FSH beta subunit($FSH{\beta}$) and GnRH receptor(GnRH-R) were evaluated by semi-quantitative RT-PCRs. The message levels of $C{\alpha}$ increased sharply during weeks 1-4, then return to the control level on week 5. The mRNA levels of $LH{\beta}$ were elevated after week 2, reached the peak at week 4, then declined to the control level after week 5. The message levels of $FSH{\beta}$ were elevated after week 2, reached the peak at week 3, then declined to the nadir at week 5. Similarly, the mRNA levels of GnRH-R were elevated after week 2, reached the peak at week 3, then gradually declined to the control level after week 5. The present study indicated that EDS treatment could induce reversible alterations in the transcriptional activities of gonadotropin subunits and GnRH-R in the anterior pituitary from male rats. EDS injection model might be useful to understand the mechanism of hormonal regulation of hypothalamus- pituitary neuroendocrine axis in male rats.

This experiment was carried out to investigate the effects of unilateral and bilateral ovariectomy in immature rats on the weight of body, ovary, uterus and adrenal gland and the change of serum FSH and LH level. Ninty Sprague-Dawley female rats, 23${\pm}$2 days old, were divided into 3 groups with 30 heads per group; control, unilaterally and bilaterally ovariectomized group. Each group was subdivided into 6 groups according to 6 experimental periods; day 4, 8, 12, 16, 20, and 24 after operation. Five rats at every 4 days intervals were measured their body weights and sacrificed for the measurement of their ovarian, uterine and adrenal weights and at the same time blood samples were taken for the determination of serum FSH and LH level by radioimmunoassay. The following results were obtained: 1. Body weights in the unilaterally and bilaterally ovariectomized goups were higher than those of control groups during all experimental periods, even though there were no significant differences among the above 3 groups. 2. A significant hypertrophy of the remained ovary in the unilaterally ovariecto mized group was observed from day 16 till day 24 after operation. The ovarian weight; 22.1${\pm}$1.73mg, at day 16 in control group was smaller than the unilaterally ovariectomized group weighing 50.5${\pm}$8.45mg (p<0.01) and the ovarian weights, 75.9${\pm}$2.25mg and 63.3${\pm}$7.08mg ; at day 20 and 24 in unilaterally ovariectomized group were significantly larger than 29.1${\pm}$2.33mg and 26.3${\pm}$1.76mg in control group, respectively (p<0.01 and p<0.05). 3. The uterus of bilaterally ovariectomized group were remarkably atrophied from day 8 after operation as compared with those of control and unilaterally ovariectomized group. The uterine weight at day 24 was 96.7${\pm}$9.15mg for control group, 139.4${\pm}$1.73mg for unilaterally ovariectomized group and 21.7${\pm}$1.08mg for bilaterally ovariectomized group, respectively and there were significant differences among 3 groups (p<0.01). 4. A statistically significant increase ofthe weight of adrenal gland was observed at day 16 in the unilaterally ovariectomized group with 24.4${\pm}$2.58mg against 15.5${\pm}$3.09mg in control group and 13.9${\pm}$1.38mg in bilaterally ovariectomized group (p<0.05). The adrenal gland weight in unilaterally ovariectomized group with 24.7${\pm}$1.63mg at day 20 and 31.2${\pm}$1.62mg at day 24 increased significantly as compared with bilaterally ovariectomized group with 15.1${\pm}$13.11mg at day 20 and 15.6${\pm}$1.76mg at day 24. 5. Serum FSH level of unilaterally ovariectomized group increased remarkably up to 2.97${\pm}$0.37mIU/ml at day 4 after operaton and then decreased gradually. Serum FSH level of bilaterally ovariectomized group were higher than those of control group throughout all experimental periods. 6. Serum LH level ofunitelarally ovariectomized group with 3.17${\pm}$0.32mIU/iml at day 4 and 3.57${\pm}$0.58mIU/ml at day 24 increased noticeably more than those of control group with 1.79${\pm}$0.16 mIU/ml at day 4 and 2.17${\pm}$0.27mIU/ml at day 24 (p<0.05).

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.

The aim of this study was to determine if the isoflavones from Sophorae fructus (SISO) have potential clinical benefit in hormone replacement therapy (HRT) for the treat ment of menopausal signs, such as the levels of total cholesterol (TC), high density lipoprotein (HDL), low density lipoprotein (LDL) and follicle stimulating hormone (FSH). An additional aim was to present the potential antioxidant effect of SISO in a microglial cell line. For the animal model, the ovaries were removed from adult rats and the indicators of menopause were measured at the pre- and post-administration time points. Although no statistically significant correlation was found, SISO tended to decrease the TC level (p=0.15) and the FSH level (p=0.36), but to increase the HDL level (p=0.303).SISO (< 5${\mu}g$/mL) also exerted antioxidant activity on BV-2 microglial cells by inhibiting lipopolysaccharide-induced nitric oxide. This cytoprotective effect was confirmed by trypan blue staining, which was used to test for cellular damage from H$_2O_2$. In conclusion, this study highlights the anti-menopausal and antioxidant effect of SISO in an ovariectomized rat model, as well as in microglial cells, and provides new clinical targets for the screening of phytoestrogens as potential candidates for HRT in menopausal women.

Objectives: This study aims to analyze the medical record of eight cases of polycystic ovary syndrome (PCOS) in a local Korean medicine clinic, in order to provide evidence on Korean medicine treatment of PCOS and to suggest the direction of future studies. Methods: The medical records of eight cases diagnosed with PCOS based on 2003 Rotterdam Criteria and whose total testosterone level was 0.53 ng/ml and over were retrospectively analyzed. The primary outcome was total testosterone level, and the secondary outcomes included luteinizing hormone (LH) and follicle stimulating hormone (FSH) levels, LH/FSH ratio, weight, last mentrual period (LMP), numerical rating scale (NRS) score of dysmenorrhea, and other associated symptoms pre- and post-treatment. Korean medicine treatment consists of the complex herbal prescription consisting of Yukmijihwang-tang, Baekho-tang, Daesiho-tang, and Gyejibokryeong-hwan, modified according to symptoms; acupuncture and electroacupuncture on 中脘 (CV12), 下脘 (CV10), 關元 (CV4), 石門 (CV5), 合谷 (LI4), 太衝 (LR3), 三陰交 (SP6), and 懸鍾 (GB39); and indirect moxibustion on 神闕 (CV8). Results: The average total testosterone level lowered statistically significantly after the treatment. The average FSH and LH levels lowered with insignificance, while the average LH/FSH ratio and weight lowered statistically significantly. During the treatment period of three to six months, every patient had the menstrual cycle shortened except for one case; and two cases with infertility problem succeeded in being pregnant. There was no adverse event. Conclusions: The Korean medicine treatment was found effective in treating PCOS, especially regarding hyperandrogenism, amenorrhea or oligomenorrhea, and infertility.

The objective of this study was to examine the effect of eCG and various concentrations (20, 40, and 80 ${\mu}g/ml$) of porcine FSH on nuclear maturation and intracellular glutathione (GSH) level of oocytes, and embryonic development after parthenogenetic activation (PA) and somatic cell nuclear transfer (SCNT) in pigs. Immature pig oocytes were matured in TCM-199 supplemented with porcine follicular fluid, cysteine, pyruvate, EGF, insulin, and hormones (10 IU/ml hCG and 10 IU/ml eCG or $20{\sim}80{\mu}g/ml$ FSH) for the first 22 h and then further cultured in hormone-tree medium for an additional 22 h. Nuclear maturation of oocytes ($85{\sim}89%$) was not influencem foreCG and various concentrations FSH. Embryonic development to the cleavage stage ($86{\sim}94%$) and mean number of cells in blastocyst ($33{\sim}37$ cells) after PA were not altered but blastocyst formation e-treignificaddlor(p<0.05) improvem forthe supplementation eith 80 ${\mu}g/ml$ FSHr(64%) compared to 47%, io8%, iand 47% in oocytes that were treated with eCG, 20,i and 40 ${\mu}g/ml$ FSH,i numectivelo. In SCNT, fusion ($78{\sim}83%$) of cell-cytoplast couplets and siosequent embryo cleavage ($82{\sim}88%$) were not influencem fordifferent gonadotropins but blastocyst formation tended to increase forthe supplementation eith 80 ${\mu}g/ml$ FSHr(25% vs. $11{\sim}18%$). Our nuults demonstrated that oocyte maturation and embryonic development after PA and SCNT e-frinfluencem fortype of gcem fortype of gits concentration. In this study, supplementation of maturation medium eith 80 ${\mu}g/ml$ FSHrimproved preimplantation development of PA and SCNT pig embryos, probably by increasing intracellular GSH concentration of matured oocytes.
