Objective: Human exposure to multiple xenobiotics, over various developmental windows, results in adverse health effects arising from these concomitant exposures. Humans are widely exposed to bisphenol A, and acetaminophen is the most commonly used over-the-counter drug worldwide. Bisphenol A is a well-recognized male reproductive toxicant, and increasing evidence suggests that acetaminophen is also detrimental to the male reproductive system. The recent recognition of male reproductive system dysfunction in conditions of suboptimal reproductive outcomes makes it crucial to investigate the contributions of toxicant exposures to infertility and sub-fertility. We aimed to identify toxicity in the male reproductive system at the mitochondrial level in response to co-exposure to bisphenol A and acetaminophen, and we investigated whether melatonin ameliorated this toxicity. Methods: Male Wistar rats were divided into six groups (n=10 each): a control group and groups that received melatonin, bisphenol A, acetaminophen, bisphenol A and acetaminophen, and bisphenol A and acetaminophen with melatonin treatment. Results: Significantly higher lipid peroxidation was observed in the testicular mitochondria and sperm in the treatment groups than in the control group. Levels of glutathione and the activities of catalase, glutathione peroxidase, glutathione reductase, and manganese superoxide dismutase decreased significantly in response to the toxicant treatments. Likewise, the toxicant treatments significantly decreased the sperm count and motility, while significantly increasing sperm mortality. Melatonin mitigated the adverse effects of bisphenol A and acetaminophen. Conclusion: Co-exposure to bisphenol A and acetaminophen elevated oxidative stress in the testicular mitochondria, and this effect was alleviated by melatonin.

Purpose : This study was undertaken to evaluate the effects of the different administration duration of Epimedium Herb extract solution on the spermatogenic abilities such as concentration, motility and morphological normality of sperm from the testis and the activities of sperm hyaluronidase. Methods : We used the 2-month-old mice and administered the extract solution of Epimedium Herb 0.3 ml/g/day for 30, 60, 90 and 120 days. The control group was administered the normal saline as the same way. We examined the number of total, motile and normal sperm from the cauda epididymis, the activities of sperm hyaluronidase. Also we observed changes of isolated testis before and after administration of Epimedium Herb extract solutions in the mice. And we compared the testicular tissue especially seminiferous tubules with the control and treated group by histochemical methods. Results : The significant differences were observed in the concentration of total sperm and normality of spermatozoa of the Epimedium Herb extract solution administered groups compared to the control group in 60, 90 and 120 days groups. The significant differences were observed the motility of the Epimedium Herb extract solution administered groups compared to the control group in 60 days group. In the histological analysis of the testicular tissues, the enlargement of testicular lobe diameter and apparent vasculogenesis between testicular lobes were observed in the Epimedium Herb extract solution administered groups compared to the control group, respectively. And the activity of hyaluronidase was significantly increased in the Epimedium Herb extract solution administered groups compared to the control group. Conclusion : This study shows that Epimedium Herb has the beneficial effect on the concentration, morphology and motility of sperm, the testicular tissues and the activities of sperm hyaluronidse in 60 days administration group. We can suggest that Epimedium Herb extract solution be useful for the treatment of male sexual dysfunction and infertility.

Purpose : These studies were undertaken to evaluate the effects of Allii tuberosi Semen (ATS) on the spermatogenic abilities such as concentration, motility and morphological normality of sperm from the testis and the activities of sperm hyaluronidase, testicular peroxidase and testicular catalase. Materials and Methods : We used the 8-week-old mice and administered the 0.2 ml extract solution of ATS in the different concentration (0.1 mg/ml, 1 mg/ml, 10 mg/ml and 100 mg/ml) once a day for 60 days. The control group was administered the distilled water in the same way. After the administration of each extract solution, we examined the number of total, motile and normal sperm, the activities of sperm hyaluronidase, testicular peroxidase and testicular catalase. Also we observed the histological changes of isolated testis. And we compared to the testicular tissue especially seminiferous tubules between control and treated group by histochemical methods. Results : The concentration of total sperm, the motility and normality of spermatozoa were significantly increased in ATS groups, especially in 1 and 10 mg/ml groups, compared to control group. In the histological analysis of the testicular tissues, the enlargement of testicular lobe diameter and apparent vasculogenesis between testicular lobes were observed in the ATS groups compared to the control group, respectively. Also, the activity of hyaluronidase was significantly increased in the ATS groups compared to the control group. In the antioxidant activity analysis, the activity of testicular peroxidase was significantly increased in the ATS groups compared to the control group, especially in 1 mg/ ml group. The activity of testicular catalase was increased in ATS groups. Conclusion : This study shows that ATS has the beneficial effect on the concentration, morphology and motility of sperm, the activities of sperm hyaluronidase and testicular peroxidase. We can suggest that ATS extract solution be useful for the treatment of male sexual dysfunctions and infertility.

Currently, infertility and artificial insemination have increased. However, there is no detailed legislation about this. In this study, I'll consider the legal status of artificial insemination child. Through the examination of the overseas legislation, we may get the reference of the future legislation. If we consider the increasing of infertility, artificial insemination should be allowed. And due to the well-being of artificial insemination child, such as the United States and France, the artificial insemination child should be regarded the legal child of the infertile couples. When the contradiction between the subject's basic rights has occurred, we need to consider the welfare of the child preferentially. Because the artificial insemination child has no selection of opportunity in birth, unlike adults who select the artificial insemination in their own free will. The development of biotechnology should be for the treatment of human. But creation and improvement of human must be prohibited. In addition, the social investigation of recognition about A.R.T. and general public administrative legal regulation should be made. There is a need for balanced discipline through a multi-disciplinary research. This study may be providing a legal interpretation criteria of other biotechnology researches.

Objectives: This study was performed to elicit the effectiveness of a herbal formula, Kamisoyo-san (Jiaweixiaoyaosan) on enhancing ovarian function in infertile woman with ovarian dysfunction. Methods: 28 patients who initially visited between November 2006 and February 2009 and were administered Kamisoyo-san until May 2009 were retrospectively evaluated for their ovarian function by means of basal FSH (b-FSH), menstrual cycle, body mass index (BMI), and body fat ratio. To identify the major factor of improving ovarian function, 28 patients were classified into two groups by criteria of patent factors, such as pre-administration b-FSH, patient age, and treatment duration, respectively. Two groups were compared in terms of pregnancy percentage, b-FSH, menstrual cycle, BMI, and body fat ratio. Results: Post-administration b-FSH significantly decreased in comparison with pre-administration (p=0.004). The higher group (b-FSH $\geq$ 25mIU/mL) in pre-administration b-FSH was more effective in decrease of post-administration b-FSH than the lower one (10mIU/mL < b-FSH < 25mIU/mL). Conclusion: Kamisoyo-san may have a therapeutic effect on the infertility of child bearing period woman with ovarian dysfunction.

Purpose: This study was undertaken to evaluate the effects of the different administration duration of Cynomorii Herba extract solution on the spermatogenic abilities such as concentration, motility and morphological normality of sperm from the testis and the activities of sperm hyaluronidase. Methods : We used the 8-week-old ICR mice and administered 0.3mg/g extract solution of Cynomorii Herba once a day for 30, 60, 90 and 120 days. The control group was administered the normal saline in the same way and duration. We examined the number of total, motile and normal sperm from the cauda epididymis. And we compared the testicular tissue especially seminiferous tubules between control and treated groups by histochemical methods. At the end we observed the difference of sperm hyaluronidase activities between control and treated groups. Results : The significant differences were observed in the concentration of total sperm, the motility and normality of spermatozoa of the Cynomorii Herba extract solution administered groups compared to the control group in 60 and 90 days groups. In the histological analysis of the testicular tissues, the enlargement of testicular lobe diameter and apparent vasculogenesis between testicular lobes were observed in the Cynomorii Herba extract solution administered groups compared to the control group, respectively. Also, the activity of hyaluronidase was significantly increased in the Cynomorii Herba extract solution administered groups compared to the control group. Conclusion : This study shows that Cynomorii Herba has the beneficial effect on the concentration, morphology and motility of sperm especially in 60 and 90 days administration group. We can suggest that Cynomorii Herba extract solution be useful for the treatment of male sexual dysfunctions and infertility.

Objectives: The aim of this study was to find out the attitude of Korean women towards IVF surrogacy which is not yet regulated by the law. Methods: We evaluated with a questionnaire, in how far IVF surrogacy was accepted in different groups of Korean women. Total 300 questionnaires were sent out to women who visited our infertility clinic, and to the nurses and office workers of our hospital. Among them, 246 questionnaires were returned, and 211 of them (85.7%) were complete and analyzed. The responders were 58 unmarried women and 153 married women including 60 infertile patients. Results: Only 17 (8.1%) women believed that IVF surrogacy was an acceptable treatment for infertile women without uterus (eg. MRKH or hysterectomized patients), and 125 (59.2%) women chose the adoption. There were no significant differences in response amongst different age group, marital status, or in relation to income level or educational level, or infertility status. A significantly higher level of acceptance was noted only in religious groups, especially in Christians. Most of responders (66.5%) chose unrelated and unknown women as a desirable host, and 28.4% of responders chose the sister or sister-in-law. Conclusions: Overall the different groups were critical towards IVF Surrogacy in Korea, irrespective of the infertile patient group. Despite the established clinical ability to have her own genetic child in women without uterus, this survey reveals that only minority supports the IVF surrogacy. So we need the survey with large, randomized population and then make a regulation about the IVF surrogacy in law.

Objective: To measure Irish opinion on a range of assisted human reproduction (AHR) treatments. Methods: A nationally representative sample of Irish adults (n=1,003) were anonymously sampled by telephone survey. Results: Most participants (77%) agreed that any fertility services offered internationally should also be available in Ireland, although only a small minority of the general Irish population had personal familiarity with AHR or infertility. This sample finds substantial agreement (63%) that the Government of Ireland should introduce legislation covering AHR. The range of support for gamete donation in Ireland ranged from 53% to 83%, depending on how donor privacy and disclosure policies are presented. For example, donation where the donor agrees to be contacted by the child born following donation, and anonymous donation where donor privacy is completely protected by law were supported by 68% and 66%, respectively. The least popular (53%) donor gamete treatment type appeared to be donation where the donor consents to be involved in the future life of any child born as a result of donor fertility treatment. Respondents in social class ABC1 (58%), age 18 to 24 (62%), age 25 to 34 (60%), or without children (61%) were more likely to favour this donor treatment policy in our sample. Conclusion: This is the first nationwide assessment of Irish public opinion on the advanced reproductive technologies since 2005. Access to a wide range of AHR treatment was supported by all subgroups studied. Public opinion concerning specific types of AHR treatment varied, yet general support for the need for national AHR legislation was reported by 63% of this national sample. Contemporary views on AHR remain largely consistent with the Commission for Assisted Human Reproduction recommendations from 2005, although further research is needed to clarify exactly how popular opinion on these issues has changed. It appears that legislation allowing for the full range of donation options (and not mandating disclosure of donor identity at a stipulated age) would better align with current Irish public opinion.

Intracytoplasmic sperm injection (ICSI) has been widely used to treat couples with infertility due to severely impaired sperm charateristics and for whom conventional in-vitro fertilization (IVF) had failed. The extent to which the morphology of the oocyte at the light microscopy level is related to the results of ICSI vis controversial. In this study, oocytes from 44 patients were reviewed. The ICSI procedure was recorded through CCD camera. The oocytes were divided into five groups according to the presence of cytoplasmic inclusions, the width of perivitelline space (PVS), the presence of cell debris in PVS, the status of first polar body and the flexibility of oolemma. The results showed that the fertilization rate and embryonic development were not associated with the morphological criteria of oocyte. The degeneraton rate of oocytes after ICSI was significantly higher (P<0.001) in the oocytes whose membranes were broken at the moment of insertion (17.7%) than the oocytes whose membranes were broken by aspiration of cytoplasm (1.6%). More oocytes with cytoplasmic inclusions (48.4% vs. 25.1%, p<0.001), wide PVS (35.2% vs. 19.0%, p<0.001), or cell debris in PVS (53.3% vs. 38.4%, p<0.05) were observed in patients with female factor infertility compared to patients with male factor infertility. These results .suggest that the fertilization rate and embryonic development after ICSI are not correlated with oocyte morphology based on the presence of cytoplasmic inclusions, size of PVS, the presence of cell debris in PVS and the status of polar body. And the degeneration rate of oocytes after ICSI was associated with the flexibility of oolemma.
