  • This study was undertaken in an effort to product embryos through in vitro maturation(IVM), in vitro fertilization(IVF) and in vitro culture(IVC) after cryopreservation of immature and mature porcine oocytes. The experiments were conducted to investigate IVM rate of oocytes frozen with 3 different cryoprotectants and to examine IVF and IVC of frozen-thawed oocytes. The CEI(cumulus cells expansion index) after IVM of frozen-thawed immature oocytes was higher in oocytes frozen with PG+PEG(propylene glycol plus polyethylene glycol) than those frozen with single cryoprotectant and this index was almost 90% of unfrozen oocyte's index(2.39 vs. 2.66). The IVF rate of all frozen oocytes was very low(68% of unfrozen oocytes) and the IVF rate of frozen immature oocytes was slightly higher than that of frozen mature oocytes(39.0% vs. 34.4%), but polyspermic penetration was higher in frozen immature oocytes(21.9% vs. 19.1%). The cleavage rate after IVF of frozen-thawed oocytes was 9.3% for frozen mature oocytes and 11.3% for frozen immature oocytes and this rate was significantly lower(P<0.05) than that of control(60.7%). The development to 8-cell stage was greatly lower in frozen mature oocytes than in frozen immature oocytes. The results indicate that the use of PG plus PEG as cryoprotectant may be very effective for vitrification of porcine oocytes and the frozen-thawed immature porcine oocytes can be used fro in vitro embryo production based on IVM, IVF and IVC system.

  • Purpose: The purpose of this paper is to report the effect of Korean medicine treatments on a female and a male patient who were infertile and failed to in vitro fertilization(IVF) treatment. Methods: The patients are a 30-year-old female who had been diagnosed with the ovulation dysfunction caused by the depression of ovarian function, and a 33-year-old male who had been diagnosed with sperm defect. The female patient alone underwent Korean medicine treatment after the eighth failure in IVF treatment and the male patient received Korean medicine treatment along with his wife after he failed in the first IVF treatment. The Korean medicine applied include herb-medicine administration, acupuncture, moxibustion, Jwa-Hun, and Du-Han-Jok-Yeol treatment. Results: Through Korean medicine treatment the female patient had succeeded in the IVF treatment and she also recovered completely from allergic rhinitis. The male patient whose wife also received Korean medicine treatment with him got his wife pregnant naturally. Conclusions: This result concludes that Korean medicine treatment is effective in infertile patients. Therefore, there needs to be more of subsequent research on infertile patients that is based on Korean medicine treatment.

  • The research work was undertaken to determine an effective fertilization medium, sperm separation method and sperm capacitating agent for optimum in vitro fertilization (IVF) rates of indigenous zebu cow oocytes. In experiment 1, tissue culture medium (TCM 199), Tyrode's albumin lactate pyruvate (TALP) and Brackett and Oliphant (BO) medium were used as basic medium for IVF of oocytes of indigenous zebu cows. In experiment 2, three sperm separation methods namely centrifugation, swim up and percoll gradient methods were used for separation of motile and viable spermatozoa for IVF. In experiment 3, for capacitation of spermatozoa, IVF medium supplemented with the heparin, mixture of penicillamine, hypotaurine and epinephrine (PHE) or the combination of heparin with PHE were used for fertilization. In vitro culture (IVC) of presumptive zygotes was done in modified synthetic oviduct fluid (mSOF) medium using standard procedure 24 h after sperm-oocytes co-culture. The cleavage rate was determined to evaluate the efficacy of fertilization medium, sperm separation method and sperm capacitating agent 24 h after IVC. The cleavage rate was higher in oocytes fertilized in TALP (63.3%) than in TCM 199 (47.5%) (p < 0.05). The cleavage rate was higher in oocytes fertilized by spermatozoa separated by percoll gradient method (62.3%) than by centrifugation (51.6%) (p < 0.05). The cleavage rate of oocytes was higher when insemination was done with spermatozoa capacitated in TALP supplemented with heparin and PHE (61.3%) compared to control (40.9%) (p < 0.05). In conclusions, TALP based medium and percoll gradient sperm separation followed by capacitation with combination of heparin and PHE are suitable for IVF of indigenous zebu cow oocytes in Bangladesh.

  • The techniques of IVM, IVF and IVC of canine oocytes may provide useful information for gamete salvage programs and the conservation of endangered canidae. This investigation has been made to determine the efficiency of in vitro maturation (IVM) as a basic experiment to study the development of canine oocytes after in vitro fertilization (IVF). The rate of oocytes developing to the Mil stage was higher in the hormone treated group (10 IU/ml hCG+eCG, 14.7%, p<0.05) than in the control group (0 IU/ml hCG+eCG, 10.0%). The monospermy and pronuclear rates of canine oocytes were investigated after caffeine treatment on IVF. Canine oocytes were fertilized in the Fert-TALP medium supplemented with 0, 10, 20 or 30 mM caffeine (Fert I, Fert II, Fert III or Fert IV, respectively). The highest pronuclear formation rate was obtained in the Fert I for 24 h IVF (6.7%, 6/89). Therefore, it is believed that unlike in other mammals, caffeine in canine IVF does not increase the efficiency of fertilization rate, and is not an important factor.

  • A phenomenological study was conducted to investigate the experiences of mothers pregnant via in vitro fertilization (IVF). Sample of nine mothers participated. Ten theme clusters emerged when the formulated meanings were organized into categories. During the infertility period, the participants were subject to self- depreciation, envy, anxiety, and depression. It changed their priorities in life from a job-oriented life to one where having a baby was the most important thing. After trying numerous alternative therapies, IVF became their last hope in having a baby. Since the success rate for IVF is low (only 20-30%), the participants for the treatment were overwhelmed with uncertainty, and it led to further anxiety, depression and despair. Success of pregnancy gave them extreme satisfaction, but they became very cautious in their day-to-day life because of their fear of abortion and early delivery. Some were even worried about the side effect of IVF during the pregnancy. Finally, the delivery of the baby gave them relief from the obligation of having a baby. Women did not have any difficulties in rearing a "test tube baby" except in the case of twins. Most women had no ethical difficulty in having a baby by IVF. However they did not wish this information to be revealed to other people. They again turned to IVF to have a son(s) when the resultory child(s) was a daughter(s). This is because of the strong preference for sons in Korean society.

  • 최근 몇년전부터 한국에서도 In Vitro Fertilization - Embryo Transfer Program(IVF-ET)에 대한 논의가 있어왔다. 현재 몇몇 종합병원 및 개인 산부인과 의원에서 수십명의 난관 유착환자를 위한 IVF가 시도되었으나 아직까지, 한건도 성공되었다는 보고는 없다. 몇 십명이 실험적 모델로 제공되었으나 한 건의 성공사례도 없었다는 것은 문제점이 있는 것이 분명하며 이러한 한국에서의 문제점을 시설 문제와 전문가 또 IVF 과정에서의 technical problem들을 종합해서 다루어 보고져 하는 것이 본 논의의 주제임을 먼저 밝혀둔다.

  • Objective: The decision to use in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), or split insemination (IVF-ICSI) in the first cycle is based on the number of motile sperm. Hence, total fertilization failure (TFF) often occurs during IVF cycles, despite normozoospermia. To investigate whether the cumulative motile swim-up spermatozoa percentage at 22 hours post-insemination (MSPPI) is an indicator for ICSI, we analyzed TFF, fertilization, blastocyst development, chemical pregnancy, clinical pregnancy, and live birth rates. Methods: This prospective study was performed using data obtained from 260 IVF cycles. At 22 hours after insemination, the remaining swim-up spermatozoa were observed and divided into six groups according to MSPPI (<10%, 10% to <30%, 30% to <50%, 50% to <70%, 70% to <90%, and 90% to 100%). Results: Regardless of the ejaculated motile sperm concentration ($0.6-280{\times}10^6/mL$ motile spermatozoa), the incidence of TFF significantly increased when MSPPI was <10%, and the fertilization rate significantly decreased when MSPPI was <30%. We found that cumulative MSPPI correlated with the cumulative fertilization rate (Spearman correlation, 0.508, p<0.001). Regarding embryo development, we observed no significant differences in the rates of blastocyst development, chemical pregnancy, clinical pregnancy, or live birth among all groups. Conclusion: Our findings suggest that MSPPI is a viable indicator for split IVF-ICSI and ICSI. Taken together, by employing the MSPPI test in advance before IVF, ICSI, or split IVF-ICSI cycles, unnecessary split IVF-ICSI and ICSI may be avoided.

  • Objectives: The purpose of this systematic review is to assess the effects of herbal medicine with in vitro fertilization-embryo transfer (IVF-ET) based on the current evidence. Methods: Eligible randomized controlled trials (RCT) searched from Pubmed which compared a combination of herbal medicine and IVF with IVF alone were included. Results: Sixteen trials, in which 2025 women involved, were included in this review. The review results showed that the effect of traditional herbal medicine can improve the clinical pregnancy rate (herbal medicine intervention: 30.36~63.64%, Control: 9.38~47.5%) and rate of high quality oocytes and embryos. The mechanism may be through regulating follicular fluid to improve microenvironment for oocytes which would lead to a successful embryo implantation. Conclusions: This analysis showed that combination of IVF and traditional herbal medicine used in the included trials improve clinical pregnancy rate and IVF success. During in vitro fertilization, TCM can regulate the microenvironment in the follicular fluid to mature the oocyte, improve the quality of the embryo, and help the development and implantation of the embryo. Further large randomized placebo controlled trials are needed to confirm the effectiveness of traditional herbal medicine with concurrent IVF.

  • Purpose: The purpose of this study was to identify the effects of a Yoga-focused prenatal program on the stress, anxiety, self confidence and labor pain of pregnant women who had in vitro fertilization (IVF) treatment. Methods: A quasi experimental study with a non-equivalent control group pretest-posttest design was used. The data collection period and meditation program were between January 9 and August 31, 2009. Forty-six women who were pregnant following IVF, and were between 12-20 weeks gestation, participated in the study (23 experimental group, 23 control group). Data were analyzed using Chisquare test, Mann-Whitney U Test, ANCOVA, and Cronbach's alpha coefficients with the SPSS 12.0 for Windows Program. Results: Although the sample size was limited, women who participated in the program showed statistically significant improvements in stress, anxiety, labor pain, and labor confidence for women pregnant after IVF. Conclusion: The result indicate that this 12-week Yoga-focused educational program can be utilized for women pregnant following IVF to reduce their stress, anxiety, and labor pain, and to increase delivery confidence. It is suggested that the Yoga-focused educational program be offered to every pregnant woman.

  • Objectives: Spontaneous pregnancy is a rare event after repeated failure of in vitro fertilization (IVF) or Intrauterine insemination (IUI) treatment. So this paper is to report the natural pregnancy of Gamiseogagjihwang-tang treatments on two infertile patients who were repeatedly failed in IVF or IUI. Methods: One patient was a 35-year-old patient diagnosed with the adenomyosis and contralateral tubal obstruction, treated with 90 cc Gamiseogagjihwang-tang two times per day for 6 weeks after second failure of IVF. The other patient was a 34-year-old patient undergone induced abortion by three times, treated with 90 cc Gamiseogagjihwang-tang two times per day for 4 weeks after second failure of IUI. Results: Through taking Gamiseogagjihwang-tang without assisted reproduction techniques, two cases got pregnant naturally. Conclusions: These cases suggest that Gamiseogagjihwang-tang is effective in treating infertile female after failure in IVF or IUI and inducing spontaneous pregnancy. Therefore, there needs to be more trial on infertile patients treated with Seogagjihwang-tang.
