The present study was accomplished to investigate the relation between menstrual cycle and ovulation by studying the fluctuation of FSH, LH, estrogen and progesterone concentration in serum samples of selected senior high school women with normal and delayed menstrual cycles after administration of Jokyungijongoktang which was a widely used herb medicine for controlling abnormal menstrual cycles. The obtained results were summarized as follows : 1. There was a significant increase of FSH concentration in women with delayed menstrual cycles after administration of Jokyungjongoktang during the preovulatory phase. 2. Jokyungiongoktang produced a significant elevation od LH concentration in women with normal and delayed menstrual cycles, respectively, during the critical interval of ovulation. 3. Estrogen concentration was significantly decreased in women with delayed menstrual cycles after administration of Jokyungjongoktang during the critical interval of ovulation. 4. Peogesterone concentration significantly increase in women with delayed menstrual cycles after administration of Jokyungjongoktang, respectively, during the postovulatory phase. According to the above results, it can be considered that Jokyungjongoktang restore menstruation and pregnancy-related hormones to normal serum levels of women with normal menstrual cycles by activating maturation of ovum and action of estrogen during the preovulatory phase, ovulation and progesterone synthesis during the critical interval of ovulation, and nidation and endometrium sufficient for the continued pregnacy during the postovulatory phase in women with delayed menstrual cycles.

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.

Photoperiodism is an important adaptive phenomenon in various physiological parameters including reproduction to cope with seasonal changes. Involvement of extraretinal photoreceptors in the photoperiodism in non-mammalian vertebrates has been well established. In addition, circadian clock system is known to be involved in the photoperiodic time measurement. The pathway consists of light-input system, time measurement system (circadian clock), gonadotropin releasing hormone (GnRH) production in the hypothalamus, luteinizing hormone (LH) and follicle stimulating hormone (FSH) production in the pituitary, and final gonadal development. Recently, several laboratories reported photopigments newly cloned in the pineal, eyes and deep brain in addition to already known visual pigments in the retina. These are pinopsin, parapinopsin, VA-opsin, melanopsin, etc. All these photopigments belong to the opsin family having retinal as the chromophore. However, the function of these photopigments remains unknown. I reviewed the studies on the location of the photopigments by immunocytochemistry. I also discussed the results on the action spectra for induction of gonadal development in relation with the location of the photoreceptors. Various physiologically active substances distribute in the vertebrate brain. Such substances are GnRH, GnIH, neuropeptide Y, vasoactive intestinal peptide, c-Fos, galanin, neurosteroids, etc. I summarized the immunhistochemical studies on the distribution and the photoperiodic changes of these substances and discussed the route from the deep brain photoreceptor to GnRH cells.

Contrast to mouse where its in vitro maturation rates are high without specific supplements or presence of the cumulus cells, there are some species, such as porcine, where its in vitro oocyte maturation rates are still very low. This comparative study was conducted to investigate the role of malate dehydrogenase(Mor2) during oocyte maturation by RNAi in the mouse and porcine. The Mor2 double-stranded RNA(dsRNA) was prepared speciesspecifically and microinjected into the cytoplasm of denuded germinal vesicle(GV) oocytes. Oocytes were cultured for 48 h(porcine) and 16 h(mouse) in M199 with 10% porcine follicular fluid, pyruvate, p-FSH, EGF, cystein, and estradiol-$17{\beta}$. We measured changes in oocyte morphology, maturation rates and mRNA levels after Mor2 RNAi. We confirmed gene sequence-specific knock down of Mor2 mRNA in both species after Mor2 RNAi. In contrast to our previous finding that mMor2 RNAi resulted in GV arrest in the mouse, we found that pMor2 RNAi resulted in MI arrest in denuded porcine oocytes(58%), but developed to MII(84.4%) in COCs. To determine whether this difference between mouse and porcine RNAi is due to differences in culture media, we cultured mouse oocytes in the M199 media for 16 h after mMor2 RNAi. Mouse oocytes were developed to MII stage(62%) and there was no statistical difference compared to that of non-injected(76.8%) and buffer-injected(73.3%) control groups. Therefore, we concluded that the mouse and porcine oocytes are having different metabolic systems in relation to malate dehydrogenase for oocyte maturation. This could be a basis for differences in maturation rates in vitro in two species. Further scrutinized studies on the metabolic pathways would led us in finding better culture system to improve oocyte maturation rates in vitro, especially in more challenging species like the porcine.

Objective: To evaluate correlations between serum anti-M${\ddot{u}}$llerian hormone (AMH) levels, phenotypes of polycystic ovary syndrome (PCOS), obesity, and metabolic parameters in patients with PCOS. Methods: A total of 175 patients with PCOS were diagnosed according to the Rotterdam Consensus were included. Exclusion criteria were age over 40, FSH>25 mIU/mL, and 17a-OHP>1.5 ng/mL. The Phenotypes of PCOS were divided into a severe form (oligo-anovulation, ANOV/hyperandrogenism/polycystic ovary morphology [PCOM]; n=59) and a mild form without HA (ANOV/PCOM, n=105). The serum AMH levels were classified into 3 groups (<5 vs. 5-10 vs. >10 ng/mL). Obesity was defined as body mass index (BMI) ${\geq}25kg/m^2$ (n=34). Results: The mean age was $25.9{\pm}5.7$ year and mean AMH level was $10.1{\pm}5.4$ ng/mL. The BMI ($kg/m^2$) was higher in group 1 ($24.2{\pm}6.3$) than in group 2 ($21.9{\pm}4.3$, p=0.046) or group 3 ($21.6{\pm}3.3$, p=0.019). There was no difference among the three groups in age, menstrual interval, antral follicle counts, androgens, or other metabolic parameters. The obesity group showed significantly lower AMH ($7.7{\pm}3.9$ ng/mL vs. $10.7{\pm}5.6$ ng/mL), p=0.004) and low-density lipoprotein levels ($93.1{\pm}21.2$ mg/dL vs. $107.5{\pm}39.3$ mg/dL, p=0.031), and showed higher total T ($0.74{\pm}0.59$ L vs. $0.47{\pm}0.36$ ng/mL, p=0.001), free T ($2.01{\pm}1.9$ vs. $1.04{\pm}0.8$ pg/mL, p=0.0001), and free androgen index ($6.2{\pm}7.9$ vs. $3.5{\pm}3.0$, p=0.003). After controlling for age factors and BMI, the serum AMH levles did not show any significant correlations with other hormonal or metabolic parmeters. Conclusion: For PCOS patients under the age 40, serum AMH is not negatively correlated with age. High serum AMH levels can not predict the phenotype of PCOS and metabolic disturbances in PCOS patients in the non-obese group. Further study might be needed to define the relation more clearly.
