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.

Objective: The aim of this study was to establish whether differences in ovarian size exist between the right and the left ovary of the same individual in women with polycystic ovary syndrome. Methods: In total, 206 Korean women with polycystic ovary syndrome were included in this study. In all participants, a transvaginal or transrectal ultrasound examination was conducted in the early follicular phase of the menstrual cycle. Results: A significant linear correlation was found between the two ovaries with regard to antral follicle count and ovarian volume. The mean antral follicle count in the right ovary (26.75 ± 11.72) was significantly higher than that in the left ovary (23.98 ± 10.85), and the mean volume of the right ovary (11.06 ± 5.17 cm³) was significantly different from that of the left ovary (9.12 ± 4.89 cm³). Conclusion: Ovarian size is different between the right and the left ovary in women with polycystic ovary syndrome.

In this project, ovarian size and activity during the peak (November-April) and the low (May-October) breeding seasons in young and adult camels were studied. Ovaries of 92 camels (Camelus dromedarius), with clinically normal reproductive tracts, aged 3-15 years and slaughtered at Faisalabad or Lahore abattoirs over a period of 24 months, were collected. Jugular blood was collected from each animal before slaughter; the serum was separated and analyzed for oestradiol concentration. The size (length, width and thickness) and weight of each ovary were measured. Grossly observable Graafian follicles were counted and their diameter was measured using Vernier Calipers. The camels having ovaries presenting follicles more than 5 mm in diameter were taken as having active ovaries. The results showed that ovarian length, width and weight were significantly higher (p<0.05) during the peak than the low breeding season. The percentage of active ovaries was also significantly higher (p<0.01) during the peak than the low breeding season. However, the effect of season on ovarian thickness was non-significant. Similarly, the ovarian length, width, thickness, weight and activity did not vary significantly between young (3-7 years old) and adult (8-15 years old) animals. Serum oestradiol concentrations were significantly higher (p<0.05) during the peak ($67.70{\pm}1.36$ pg/ml) than the low breeding season ($15.25{\pm}1.54$ pg/ml). It was concluded that in Pakistani camels ovarian size and activity were higher during the peak than the low breeding season. However, age of the camel (from 3 to 15 years) had no effect on these parameters.

Objectives: The purpose of this study is to report the effect of combination treatment of Traditional Korean medicine (TKM) and chemotherapy on a ovarian cancer with lung metastasis patient. Methods: One ovarian cancer with lung metastasis patient was treated by TKM in conjunction with Carboplatin/paclitaxel since Feb. 2020. Repeat cycle every 3 weeks for 6 times. The patient has been treated with TKM at the same time. To evaluate the patient, symptoms were measured by Numeric Rating Scale (NRS), Eastern Cooperative Oncology Group (ECOG) and tumor size was measured by scanning with Computed Tomography (CT). Blood tests including cancer biomarker were conducted during treatment. Adverse events were evaluated by the National Cancer Institute Common Terminology Criteria for Adverse Event (NCI-CTCAE), version 5.0. Results: After treatment with Carboplatin/paclitaxel and TKM during 2 months, the size of the ovarian cancer was decreased(Partial Response, PR), size and malignant pleural effusion at right lung disappeared. And no evidence of newly developed metastatic lesions. After 2 months, the tumor response was stable disease while improving the performance and other symptoms. Conclusions: This case provides us conjunctive treatment with Conventional and Eastern medicine may have substantial benefit for patients with end-stage ovarian cancer.

With the development of fetal ultrasonography, detection of fetal ovarian cysts has been increased. Although ovarian cyst formation during the perinatal period is a self limiting process, there is still considerable controversy regarding the best treatment of the fetal ovarian cyst. The purpose of this study is to evaluate the natural history of fetal ovarian cysts and to analyze the result of treatment. From 1995 to 2004, 31 consecutive fetuses with ovarian cysts were followed by ultrasonography during the perinatal period. The fetal ovarian cyst was diagnosed by prenatal ultrasonography between 25weeks and 38 weeks and the mean size of the cysts was 5cm (ranged from 2 to 8cm). At birth, 3 cysts disappeared. In 2 cases, the diagnoses were changed to multicystic kidney disease and intestinal duplication. During following up of 26 cysts, 15 cysts have resolved completely. Seven cysts required oophorectomy because of cyst torsion (n=3), differentiation of tumorous condition (n=2), increased size of cyst (n=1), and large size (8cm) of cyst at birth (n=l). Fetal ovarian cyst should primarily be observed, and only in the limited cases, surgical treatment would be required for the risk of complications such as torsion and differentiation from benign to malignant pathology.

In order to investigate the effects of Gamikyuchoolpajingtang(GMKCPT) and Gamibojungikgitand(GBIKT) on the ovarian tumor, the ultrasonographic appearance were studied in a few patients. the results obtained were follows : 1. The administration of Gamikyuchoolpajingtang(GMKCPT) reduced significantly tumor's size in corpus uteri and uterus. 2. The administration of Gamibojungikgitang(GBIKT) reduced significantly size in the ovarian. 3. The tumors of ovarian and uterus seem to be connected with Seven Emotions. 4. In this study, it is suggested big tumors over 10cm can be treated as herbal prescription. From above findings, it is suggested that Gamikyuchoolpajingtang(GMKCPT) and Gamibojungikgitang(GBIKT) seem to reduce significantly tumor's size.

A case of ovarian teratoma is reported in a 11-year-old female Korean Jindo dog. Grossly, the left ovary was markedly enlarged ($5{\times}4{\times}4 cm in size$) and contained several cystic spaces filled with hairs and yellowish, fragile deratinous material on cross section. Histological observation of the hair and keratin containing cystic structures lined by stratified squamous epithelium, mature adipose tissue, and bone and cartilage is compatible with a diagnosis of ovarian teratoma, pyometra was also present in this dog. This is believed to be the first report on canine ovarian teratoma in Korea.

This study determined the effect of ovarian status at the beginning of the modified Double-Ovsynch program on reproductive performance in dairy cows. In the study, 1,302 cows were treated with a modified Double-Ovsynch program at 56 days after calving. This program comprises administering gonadotropin-releasing hormones (GnRH), prostaglandin F_2α (PGF_2α) 10 days later, GnRH 3 days later, GnRH 7 days later, and GnRH 56 h later, followed by timed artificial insemination (TAI) 16 h later. At the beginning of the program, cows were categorized according to the size of the largest follicle and the presence of a corpus luteum (CL) in the ovaries as follows: 1) small follicle (<5 mm, SF group, n = 100), 2) medium follicle (8-20 mm, MF group, n = 538), and 3) large follicle (≥25 mm, LF group, n = 354) without a CL, or 4) the presence of a CL (CL group, n = 310). The pregnancies per AI after the first TAI were analyzed by logistic regression using the LOGISTIC procedure, and the logistic model included the fixed effects of the herd size, parity, body condition score (BCS) at the first TAI, TAI period, and ovarian status. A larger herd size, higher BCS at the first TAI, and TAI period with no heat stress increased (p < 0.05) the probability of pregnancy per AI after the first TAI. However, ovarian status at the beginning of the program did not affect (p > 0.05) the pregnancies per AI (ranges of 37.9% to 42.9%). These results show that the modified Double-Ovsynch program can be used effectively while maintaining good fertility regardless of the ovarian status in dairy herds.

The purpose of this study was to develop a breeding technique to increase Hanwoo of superior characteristics. In the present study, reproductive status of Hanwoo such as size of farm, breeding system and gestationi length was investigated. In addition, effect of low dose administration of prostaglandin F2$\alpha$(PGF2$\alpha$) on luteolysis was examined. The size of farm was classified by the total number of cows and the number of breeding stocks, respectively. The distribution of herd size of < 5, 6~10, 11~30, 31~50 and > heads was 31%, 15%, 39%, 4% and 11%, respectively. Furthermore, the distribution of breeding stock size of <5, 6~10, 11~30, 31~50 and > 50 heads was 36%, 28%, 31%, 3% and 3%, respectively. Average parity was 2.1 in breeding stock. In breeding pattern, artificial in semination(A.I), estrus synchronization-A.I and natural mating was 92.7%, 2.4% and 4.9% respectively. Gestational length of Hanwoo was ranged 253~316 days (average length : 285 days) after estrus( estrus=0). To induce luteolysis, PGF2$\alpha$ was injected into ovarian parenchyma by a modified ovarian injector. The effect of administration of 6mg PGF2$\alpha$ on luteolysis and estrus induction was betweer (P<0.01) when PGF2$\alpha$ was administered into ovarian parechyma than when administered intramuscluarly (71 vs. 91%). When PGF2$\alpha$ was injected into ovarian parenchyma, a decreased concentration to 3 mg did not significantly decreaed its luteolytic effect(92%). When AI was performed following PGF2$\alpha$ treatment, the intraovarian injection group yielded a higher pregnancy rate(69 vs. 88%) than the IM injection groups, regardless of the dosage. In conclusion these results suggest that increasing herd size and regular reproductive management are needed to improve reproductive efficiency in Hanwoo industry. Furthermore, intraovarian administration of PGF2$\alpha$ is effective way to induce luteolysis compared with intramuscular injection.
