A 46,XY gonadal dysgenetic woman gave birth to two healthy girls following vitrified oocytes donation. The loss of SRY gene was considered as the cause of this patient. Although similar cases have been reported about pregnancies of 46,XY pure gonadal dysgenetic women, successful delivery from vitrified oocytes has been hardly reported yet. Oocytes vitrification technique provides a beneficial way by saving superfluous oocytes from the pregnancy patients to these women who need.

OBJECTIVE: To investigate the clinical significance of endometrial thickness and pattan as a predictor of successful implantation of embryos in ovum donation and cryopreserved-thawed embryo transfer program. METHODS: From January, 1996 to March, 1998, 31 cycles of ovum donation and 31 cycles of cryopreserved-thawed embryo transfer were enrolled in this prospective study. Endometrial thickness was measured three times: prior to progesterone administration (P), 1 day and 3 days after P. In cryopreserved-thawed embryo transfer cycles, the measurement at 1 day after P was omitted. Endometrial pattern was observed prior to progesterone, and was considered meaningful when a multi-layered triple-line was seen with prominent outer and central hyperchogenic lines and inner hypoechogenic regions. RESULTS: There were no differences in embryo quality, dose or duration of estrogen, and endometrial thickness or pattern between conception and non-conception cycles in both ovum donation and cryapreserved-thawed embryo transfer pmgram. In ovum donation cycles, no cortelation was observed between estrogen dose and endometrial thickness or pattern. In cryopreserved-thawed embryo transfer cycles, total estrogen dose and endometral thickness at 3 days after P has a inverse correlation, and estrogen dose over 4.3 mg per day can predict expression of a multi-layered triple-line pattern, CONCLUSION: Endometrial thickness or pattern. cannot predict a successful implantaion of embryos in both ovum donation and cryopreserved-thawed embryo transfer cycles.

Recent advances in assisted reproductive technology have been able to overcome the nearly all problems associated with traditional infertility factor. IVF and ET using donated oocyte has brought new hope to many couples who otherwise would remain childless, so oocyte donation can be the alternative treatment modality for specific fatal infertility patients. The high success rate of this procedure has led to its wide application in women with ovarian failure or dysfunction, at various ages and for various etiologies. Oocyte donation is also offered to patients who repeatedly fail to conceive with standard IVF. But there are many conflicting issues in this procedure such as moral, ethical, medical, legal problems. We review the technical aspects related with oocyte donation in infertility treatment and ethico-legal issue.

OBJECTIVES: To assess and compare the clinical outcomes between GnRH agonist long protocol and GnRH antagonist short protocol in oocyte donation program. MATERIALS AND METHODS: Of total 18 oocyte donation cycles, controlled ovarian hyperstimulation (COH) were performed with GnRH agonist long protocol and GnRH antagonist short protocol in initial 9 cycles and later 9 cycles, respectively. Oral estradiol valerate and progesterone in oil were administrated to all recipients for endometrial preparation. Oral estradiol administration was started from donor cycle day 1 after full shut down of gonadal axis with GnRH agonist in patients with ovarian function. Progesterone was injected from oocyte retrieval day of donor initially, then continuously till pregnancy 12 weeks if pregnancy was ongoing. We compared the parameters of clinical outcomes, such as number of the retrieved oocytes, fertilization rate, high grade embryo production rate, clinical pregnancy rate, implantation rate, ongoing pregnancy rate, COH duration, total gonadotropin dose for COH between GnRH agonist long protocol group and GnRH antagonist group. Statistical analysis was performed using Mann-Whitney test, p<0.05 was considered as statistically significant. RESULTS: The number of retrieved oocytes, fertilization rate, high grade embryo production rate, clinical pregnancy rate, implantation rate, ongoing pregnancy rate were 14.89+/-7.83, 81%, 64%, 78%, 31%, 78%, respectively in GnRHa long protocol group and 11.22+/-8.50, 79%, 64%, 67%, 34%, 56%, respectively in GnRH antagonist group. There was no significant differences in parameters of clinical outcomes between 2 groups (all p value >0.05). Duration and total gonadotropin dose for COH were 10.94+/-1.70 days and 43.78+/-6.8 vials in 18 cycles, 12.00+/-1.73 days and 48.00+/-6.93 vials in agonist group, 9.88+/-0.78 days and 39.55+/-3.13 vials in antagonist group, respectively. in GnRH agonist long protocol group, significantly longer duration and higher gonadotropin dose for COH were needed (p= 0.012). CONCLUSION: in oocyte donation program, clinical outcomes from controlled ovarian hyperstimulation with GnRH antagonist were comparable to those from GnRH agonist long protocol group, so controlled ovarian hyperstimulation with GnRH antagonist may be effective as GnRH agonist long protocol. At least there may not be harmful effects of GnRH antagonist on oocyte development and quality.

OBJECTIVE: Oocyte donation cycle has been a useful model for the assessment of potential factors affecting human pregnancy, such as uterine receptivity or oocyte quality. The purpose of this study was to investigate variable clinical factors affecting the outcomes of oocyte donation cycles. METHODS: This study reviewed 109 cycles of 85 women who underwent oocyte donation in SNUH infertility clinic from March 1992 to February 2004. Variable clinical characteristics were compared between pregnant and non-pregnant group. Data was evaluated by student's t-test, oneway ANOVA, and Chi-square test. RESULTS: Clinical pregnancy rate was 38.5% per cycle and 48.2% per recipient. When pregnant and non-pregnant groups were compared, there was a significant difference in donor age between both groups. (30.2+/-3.6 vs. 32.1+/-4.3, P=0.017). On the other hand, there were no significant differences in mean age, BMI, gravidity of recipient, and peak estradiol level of donor. The number of oocytes retrieved, embryos transferred, fertilization rate, and cumulative embryo score were not different between pregnant and non-pregnant group. Among the various donor age groups, clinical pregnancy rate was significantly higher in <30 years group than > or =35 years (50.0% vs 18.2%, P=0.015). There were no significant differences for both endometrial thickness and pattern in the pregnancy rate during the IVF-ET cycles by ovum donation. CONCLUSION: The most reliable predictive factor for pregnancy in oocyte donation cycles is the age of oocyte donor. The mid-cycle endometrial thickness and trilaminar patterns are insignificant predictors. The age of recipient and cumulative embryo score are also insignificant factors.

OBJECTIVES: Premature ovarian failure (POF) is a syndrome defined as the cessation of ovarian function before the age of 40 years that is characterized by amenorrhoea associated with elevated gonadotropin levels. The aim of this study was to compare clinical manifestation of primary amenorrhea and secondary amenorrhea group. METHODS: This study was designed as a retrospective multicenter study of 262 women with premature ovarian failure. Sixty eight women with primary amenorrhea and 194 women with secondary amenorrhea were evaluated and hormonal level, lipid profile, bone mineral density, and pregnancy rates were compared. RESULTS: The estradiol level was markedly lower in primary amenorrhea than secondary amenorrhea. The pregnancy rate of 43.3% before the diagnosis in secondary amenorrhea was markedly higher than the rate of 0% in primary amenorrhea. The pregnancy rates after treatment was 5.9% in primary amenorrhea, but 1.0% after diagnosis and 2.8% after treatment in secondary amenorrhea. The pregnancy rate after hormonal treatment was 3.7% in total, 8.3% in primary amenorrhea, and 2.8% in secondary amenorrhea. In nine cases of pregnancy, seven cases were after estrogen-progestin (EP), one case was after clomiphene citrate and one case was after EP/human menopausal gonodotropin (hMG). And In nine cases of pregnancy, six cases resulted from oocyte donation. The prevalence of osteopenia/osteoporosis was markedly higher in primary amenorrhea than in secondary amenorrhea. CONCLUSION: Premature ovarian failure has negative influences on the physical and psychological health of young patients. Effective management should include earlier diagnosis and intensive medical intervention to relieve symptoms of estrogen deficiency and to treat long-term disease such as osteoporosis and in assisted pregnancy by oocyte donation.

OBJECTIVETo assess the feasibility of using subclinical doses of pentazocine in painless egg retrieval.

METHODSEighty-one patients undergoing painless egg retrieval were randomized into the observation group and the control group to receive 0.4 mg/kg pentazocine with 1.5 mg/kg propofol and 0.5 mg/kg pentazocine with 1.5 mg/kg propofol, respectively. The mean arterial pressure (MAP), heart rate (HR), SPO(2), respiratory rate (RR), unconsciousness time, awake time, hospital stay, complications, consciousness during the operation and adverse effects were compared between the two groups.

RESULTSThe two groups showed no significant differences in the analgesic effect, dosage of propofol, adverse effects, unconsciousness time, awake time, or hospital stay. But compared with the control group, the observation group showed greater intraoperative consciousness but with more stable respiration.

CONCLUSIONSubclinical doses of pentazocine can be used in the painless egg retrieval, but the dose of propofol should be increased to reduce the body activity during the operation.
