Objectives: This review plans to assess the efficacy and effectiveness of oriental medicine for the treatment of Ovarian Hyperstimulation Syndrome (OHSS) through literature research and overview. Methods: Database searching was conducted to identify relevant randomized controlled trials (RCTs) on oriental medicine for the treatment of Ovarian Hyperstimulation Syndrome. Studies were searched from Journal of Korean Obstetrics and Gynecology, Korean Medical Database, Korean studies Information Service System, China National Knowledge Infrastructure, Cochrane library, PubMed and EmBase up to 21^st May, 2020. Results: Seventeen studies were finally selected. Fifteen studies intervened with oral Chinese herb medicine, two studies intervened with acupuncture and moxibustion. Nine studies concluded that intervention with oriental medicine significantly relieved OHSS symptoms. Three studies reporting ovary diameter, four studies reporting abdominal circumference and other four studies reporting pelvic effusion showed significant reduction compared to control groups. Six studies showed significantly shorter duration for hospitalization in intervention groups. Only one study showed significantly higher pregnancy rate. Factors related with vascular permeability and blood cell coagulation were significantly lowered in intervention groups in general. Conclusions: From seventeen studies, oriental medicine relieved OHSS symptoms and showed treatment effectiveness. Further strictly designed studies and long-term observed studies are needed to establish evidences.

Methods: Database searching was conducted to identify relevant randomized controlled trials (RCTs) on oriental medicine for the prevention of Ovarian Hyperstimulation Syndrome. Studies were searched from Journal of Korean Obstetrics and Gynecology, Korean studies Information Service System, Korean Medical Database, China National Knowledge Infrastructure, Cochrane library, PubMed and EmBase up to 7^th November, 2019. Results: Ten RCTs were finally selected. Eight studies intervened with oral Chinese herb medicine, one is intervened with Chinese medicine enema and the other with acupuncture. Eight studies concluded that intervention with oriental medicine significantly decreased OHSS incidence. Five studies showed significantly higher pregnancy rate in the intervention groups. Two studies reported higher ovulation rate and other two studies showed more maturated eggs than the control groups. Four studies showed opposite results in serum Estradiol level. Vascular Endothelial Growth Factor level was significantly lower in the intervention groups in two studies. Conclusions: From ten studies, oriental medicine reduced OHSS incidence rate and showed preventable effectiveness. Further strictly designed studies and acupuncture intervened studies are needed to establish evidences.

To investigate the effects of ovarian cysts on the controlled ovarian hyper-stimulation cycles, 16 patients with 16 paired cycles for IVF-ET were analyzed. These patients had taken both type of cycles, i.e., with cyst(cyst group) and without cyst(control group). Mean diameter of ovarian cysts in cyst group was 18.2mm. There were no significant differences in hormone levels in early follicular phase between two groups. No significant differences were found in total dosage of hMG(IU) administered during the ovarian stimulation $843.8{\pm}123.0$ vs $891.0{\pm}129.8$, serum estradiol level (pg/ml) on the day of hCG administration($1542.8{\pm}1100.6$ vs $1567.5{\pm}1193.0$), the number of aspirated follicles $10.0{\pm}3.4$ vs $11.2{\pm}4.3$ and oocytes $5.3{\pm}3.3$ vs $6.2{\pm}3.1$, the fertilization rate(51.2 % vs 57.2 %) and the cleavage rate(40.5 % vs 52.0 %). Serum estradiol terminal patterns during COH in one group tended to be repeated in the other group. In conclusion, this study suggests that small ovarian cysts do not adversely impact on the controlled ovarian hyperstimulation parameters in IVF - ET program and the presence of small ovarian cyst without concomitant high basal serum estradiol level is not an indication of the cancellation of the controlled ovarian hyperstimulation for IVF-ET.

This article reports a case of spontaneous ovarian hyperstimulation syndrome (OHSS) following a thawed embryo transfer cycle. OHSS, a potentially life-threatening condition, is an iatrogenic complication of controlled ovarian stimulation; therefore, it is very important to prevent and treat OHSS during treatment with ovulation-inducing agents. Despite our efforts to prevent OHSS, in this case, severe spontaneous OHSS occurred, which resulted in uncontrolled preterm labor and a preterm delivery and also persisted for 6 weeks after delivery. Freezing all embryos cannot entirely prevent the development of OHSS because OHSS can occur spontaneously. Although spontaneous OHSS remains a rare event, females with a history of OHSS may have an elevated risk for spontaneous OHSS. We suggest closely monitoring cases of pregnancy following thawed embryo transfer for early diagnosis of spontaneous OHSS and the use of conservative management.

Objective: This study was performed to compare the clinical response to controlled ovarian hyperstimulation (COH) of in vitro fertilization and embryo transfer (IVF-ET) according to the size of baseline ovarian cyst. Method: From February 1992 to March 1999, a retrospective analysis was done of 272 cases who underwent COH using mid-luteal phase long protocol of gonadotropin-releasing hormone agonist (GnRH-a) for IVF-ET. These cases were divided into four group; group 1 (n=63) had cysts with mean diameters between 20.0 and 29.0 mm on their baseline ultrasound on cycle day 3, group 2 (n=57, $30.0{\sim}49.0mm$), group 3 (n=68, >50.0 mm) and control group (n=84). Cases were excluded according to the following criteria; pure male factor infertility, the presence of only one ovary, high CA-125 level and previous endometriosis. Results: There were no statistically significant differences between cases with baseline ovarian cyst <50.0 mm in diameter and control group in any of the parameters. However, cases with baseline ovarian cyst>50.0 mm in mean diameter needed more amount of human menopausal gonadotropin (hMG), showed significantly lower estradiol ($E_2$) level, the number of follicle >15.0 mm on the day of human chorionic gonadotropin (hCG) administration, the number of oocytes retrieved, the number of mature oocytes, and pregnancy rate compared with control group. Conclusion: This study suggests that cases with baseline ovarian cyst <50.0 mm in diameter do not adversely impact on IVF-ET outcome. However, cases with baseline ovarian cyst >50.0 mm in diameter had adverse effects on various parameters. Therefore, to improve the outcome of IVF-ET in these cases, ovarian cyst aspiration prior to initiating COH may be required.
