Objective: The aim of this study was to compare GnRH antagonist and agonist flare-up treatment in the management of poor responder patients. Methods: One hundred forty-four patients from Jan. 1, 2002 to Aug. 31, 2005 undergoing IVF/ICSI treatment who responded poorly to the previous cycle (No. of oocyte retrieved$\leq$5) and had high early follicular phase follicle stimulating hormone (FSH>12 mIU/ml were selected. Seventy-five patients received agonist flare-up protocol and 71 patients received antagonist protocol. We analyzed the number of oocytes retrieved, number of good embryos (GI, GI-1), total dose of hMG administered, implantation rate, cycle cancellation rate, pregnancy rate, live birth rate. Results: The cancellation rate was high in antagonist protocol (53.5% vs. 30.1%). The number of oocyte retrieved, the number of good embyos were high in agonist flare-up group. There was no statistical difference between GnRH agonist flare up protocol and GnRH antagonist protocol in implantation rate (14.5%, 10.1%), clinical pregnancy rate per transfer (29.4%, 21.2%) and live birth rate per transfer (21.6%, 18.2%). Although the result was not statistically significant, GnRH agonist flare up group showed a nearly doubled pregnancy rate and live birth rate per initial cycle than GnRH antagonist group. Conclusions: The agonist flare-up protocol appears to be slightly more effective than the GnRH antagonist protocol in implantation rate, pregnancy rate, live birth rate but shows statistically no significance. Agonist flare-up protocol improved the ovarian response in poor responders. However, based of the result of the study, we can expect improved ovarian response in poor responders by GnRH agonist flare up protocol.

The purpose of this study was to examine obstetrical & gynecological health status and body composition for married female immigrants. The participants were 154 immigrant women living in Busan. Data were collected from July 2008 to July 2009 using a questionnaire and a bioelectrical impedance analysis tool (Inbody 720) for analysis of body composition. Most subjects were in the normal range for body composition, but some of those who answered the questionnaire had experienced some gynecological problems such as dysmenorrhea, or irregular menstruation. There was a significant difference in experiences with in vitro fertilization, pregnancy and abortion according to age and in premensturaion syndrome, as well as differences in regulation of menstruation during the past year, leukorrhea odor, experiences in in vitro fertilization, and delivery and breastfeeding according to nationality. There were significant differences in body mass index and waist-hip ratio according to age, as well as differences in percent body fat, body mass index and waist-hip ratio according to nationality. There were also significant differences in body mass index and waist-hip ratio according to period of stay in Korea. Procreative care protocols concerning married female immigrants' characteristics should be developed.

Purpose: To report the effect of oriental medicine on a infertile patient with endometriosis diagnosed as a IVF case due to pelvic adhesion. Methods: The patient who had infertility problem with pelvic adhesion from endometriosis in spite of 2 times of IVF trials was treated with the oriental medicine such as herbal medication, herbal acupuncture and moxibustion therapy, and so forth. Results: After the oriental medical treatments, the patient could give a natural birth to a healthy baby. Conclusion: This case report shows that the oriental medical treatment is effective for treating infertility of endometriosis with pelvic adhesion.

Combined intrauterine and ectopic (heterotopic) pregnancy occurs in approximately 1 in 30,000 spontaneous gestations. Heterotopic gestations are increased in women who have had reconstructive pelvic surgery, pelvic inflammatory disease and artificial ovarian hyperstimulation. Patients who require assisted reproductive technologies, such as in vitro fertilization / embryo transfer and gamete intrafallopian transfer, also have an increased risk of a heterotopic pregnancy. We experienced two cases of combined pregnancy following IVF-ET. Following is a report of these cases with a brief review of references.

This is a report concerning IVF-ET program and its outcomes of the reproductive center of the Ohio State University(OSU). The pregnancy rate/laparascopy in the OSU reproductive center was average 12.2%. However, the fertilization rate was lower than other reporters. The other problem of the OSU reproductive center was that there was no success in the field of cryopreserved embryo and donor embryo. Therefore, many aspects such as hyperstimulation protocol, culture systems, and embryo transfer technique should have to be reevaluated in order to enhance the outcome of IVF-ET program in the OSU reproductive center.

A prospective study was undertaken to test whether immunosuppression improves implantation, pregnancy rates and their outcomes in an in-vitro fertilization-embryo transfer( IVF-ET) cycles in patients with tubal factor infertility. The implantation and pregnancy rates was not significantly higher in patients recieving prednisolone than in control patients in routine IVF-ET cycles and unstimulated IVF-ET cycles. It can be concluded that prednisolone dose not support implantation and pregnancy outcomes of in routine IVF-ET cycles at least.

A total of 55 patients with various etiologies of infertility particitated in a study comparing two regimens of controlled ovarian hyperstimulation (COH) with GnRH agonists and gonadotropins. Nineteen patients were given an ultra-short stimulation protocol when the agonist was administered for 3 day from Day 2 of the cycle. The remaining 36 patients were given a long stimulation protocol when the agonist was administered from the mid-luteal phase of the cycle preceding the stimulation cycle. The mean number of gonadotropins used per patient was not different between two groups. No significant differences were found in the mean number of oocytes recovered, fertilization rate and embryo cleavage rate between two groups. Pregnancy and delivery rates were higher in ultra-short protocol than in long protocol, but these were not significant. These results suggest that an ultra-short protocol is as effective as a long protocol in in-vitro fertilization and embryo transfer.

The purpose of this study is to improve fertilization rate in IVF-ET program of patients with male infertility used micromanipulation technique, partial zona dissection (PZD) or micro-insemination by sperm transfer (MIST). The results were as follows 1. The fertilization rate of non-micromanipulated oocytes and micromanipulated (PZD) oocytes were 12.5% (n=2) and 42.2% (n=19), respectively, and showed significant differences between two groups (p<0.05). 2. The fertilization rate of micromanipulated (MIST) oocytes was 30% (n=27). 3. The damage rate of Group 1 (PZD) and Group 2 (MIST) were 15.7% (3/19) and 29.6% (8/27), respectively. 4. One pregnancy resulted following replacement of micromanipulated (MIST) embryos in 4 patients.
