Objective: The aim of this study was to evaluate pregnancy outcomes and the live birth rate at 1-year age increments in women aged ${\geq}40years$ undergoing fresh non-donor in vitro fertilization (IVF) and embryo transfer (ET), and to identify predictors of success in these patients. Methods: This retrospective study was performed among women ${\geq}40years$ of age between 2004 and 2011. Of the 2,362 cycles that were conducted, ET was performed in 1,532 (73.1%). Results: The clinical pregnancy rate and live birth rate in women ${\geq}40years$ significantly decreased with each year of increased age (p<0.001). Maternal age (odds ratio [OR], 0.644; 95% confidence interval [CI], 0.540-0.769; p<0.001), basal follicle-stimulating hormone (FSH) levels (OR, 0.950; 95% CI, 0.903-0.999; p=0.047), the number of high-quality embryos (OR, 1.258; 95% CI, 1.005-1.575; p=0.045), and the number of transferred embryos (OR, 1.291; 95% CI, 1.064-1.566; p=0.009) were significant predictors of live birth. A statistically significant increase in live birth rates was seen when ${\geq}3$ embryos were transferred in patients 40 to 41 years of age, whereas poor pregnancy outcomes were seen in patients ${\geq}43years$ of age, regardless of the number of transferred embryos. Moreover, the cumulative live birth rate increased in patients 40 to 42 years of age with repeated IVF cycles, but the follicle-stimulating hormone in those ${\geq}43years$ of age rarely showed an increase. Conclusion: IVF-ET has acceptable outcomes in those < 43 years of age when a patient's own oocytes are used. Maternal age, basal FSH levels, and the number of high-quality embryos and transferred embryos are useful predictors of live birth.

Mycoplasmas have long been suspected of contributing to involuntary infertility in couples. However considerable disagreement exits concerning the role of genital mycoplasma infection in human infertility. Several investigators have noted abnormalities in the semen analysis of men with positive mycoplasma cultures, and early epidemiologic studies indicated that Ureaplasma urealyticum was linked to human reproductive failure on the basis of higher frequencies of isolation from infertile versus fertile couples and successful pregnancies in infertile couples after doxycycline therapy. However, subsequent investigators have questioned these findings because there are many studies in which treatment for mycoplasma in the male or female did not demonstrate an improved pregnancy rate, and semen samples from unexplained infertile men containing ureaplasmas have not revealed poorer motility, fewer spermatozoa and more aberrant forms. The objective of this study were to investigate the incidence rate of mycoplasma in semen and to investigate whether the presence of mycoplasma in semen makes significant difference to the semen volume, sperm motility and sperm counts. The results were that the rate of isolation of mycoplasma species was 70.3%. Semen volume is $2.84{\pm}1.01ml$ for culture negative and $3.15{\pm}1.42ml$ for culture positive group. Sperm motility is $46.23{\pm}15.80%$ for culture negative and $50.09{\pm}15.69%$ for culture positive group, and sperm count is $95.47{\pm}47.14({\times}(P)10^6/ml)$ for culture negative and $86.73{\pm}47.59({\times}10^6/ml)$ for culture positive group. In conclusion, we suggest that the presence of mycoplasma in semen makes no significant differences to the sperm parameters.

Purpose: This study examined degrees of irrational parenthood cognition, post traumatic stress disorder (PTSD), spousal support, and quality of life and investigated factors that influence the quality of life of infertile women. Methods: Research design was a cross sectional correlational survey with a total of 113 female patients receiving treatment for infertility. Data were collected from August 1 to November 30, 2015. The collected data were analyzed using t-test, ANOVA, Pearson's correlation, and multiple regression analysis. Results: The mean score of the quality of life was $59.0{\pm}14.8$. The quality of life was significantly associated with irrational parenthood cognition (r=-.70), post traumatic stress disorder (r=-.65), and spousal support (r=.56). The factors significantly affecting the quality of life in infertile women were irrational parenthood cognition (${\beta}=-.45$), post traumatic stress disorder (${\beta}=-.34$), and spousal support (${\beta}=-.32$). The explained variance by these factors was 70.4%, and the regression model was valid (F=89.81, p<.001). Conclusion: This study may contribute to the development of nursing intervention program to improve the quality of life of infertile women.

Known as a female hormone, estrogen, performs important functions, and the activities of the hormone are mediated via the estrogen receptor. The principal objective of the present study was to assess the effects of a estrogen receptor agonist in male reproductive organs. In this study, the estrogen receptor alpha agonist, PPT, was injected subcutaneously into adult male mice. The effects of PPT on the murine reproductive system were histologically assessed at 3,5, and 8 weeks after treatment. In the treatment group, reductions were observed in the weight of the body, testis and epididymis. Microscopic examination revealed a reduction in seminiferous tubular diameter in the testis, and epithelial cell height in the epididymis during the experiment. 8 weeks after treatment, spermatogenesis was not detected, nor was the lumen of the seminiferous tubules. In the fertility test, 1 week after PPT injection, the fertilizing ability of males was decreased, and on the 2nd and 3rd weeks, complete infertility was observed. In conclusion, the injection of high concentrations of PPT into adult males induced physiological changes, including infertility, and also induced morphological changes, including a reduction in the height of epithelial cells within the reproductive system.

We found reports of only about 20 cases of well documented ejaculatory duct obstruction presenting with infertility and treated by TUR. While infertility caused by ejaculatory duct obstruction is rare accurate diagnosis by vasoseminal vesiculography is important, since these obstructions may be treatable. In our 29 patients undergoing vasoseminal vesiculography for 1 year to demonstrate obstruction site in seminal tract the ejaculatory duct obstruction was found in 6 patients. The intial methods of treament were TUR of the ejaculatory duct in 2 patients, forceful lavage of ejaculatory duct through the vas deferens in 4 patients. One patient's wife who had undergone TUR of the ejaculatory duct delivered a normal female baby 15 months postoperatively. In one patient who had undergone forceful lavage of ejaculatory duct semen analysis returns to normal level except the motility. When initial methods of treatment fail to get the normal semen we have the plan to perform TUR of the ejaculatory duct or aspiration of seminal fluid in the seminal vesicle under the control of the ultrasonography for AIH according to the level of ejaculatory duct obstruction. Our report suggests that ejaculatory obstruction has been underdiagnosed and should receive more attention by urologist.

Reproductive dysfunction is a major health concern amongst the inhabitants of Tana River County. An ethno botanical study was conducted in Garsen, Itsowe and Ngao sub divisions of Tana River County to document the utilization of medicinal plants for the management of female reproductive ailments. The target population was practicing herbalists from Pokomo, Ormo and Giryama communities in the study area. Structured questionnaires and focussed group discussions were used to collect data. Forty eight plant species distributed in 40 genera and 29 families were documented as being important for the management of pregnancy related complications, menstrual disorders, infertility, fibroids and as contraceptives. The species most frequently cited by the herbalists were fourteen. Fifty two percent of the plant species were probably being mentioned for the first time as being useful in reproductive health management. In conclusion, Tana River has a pool of TMPs with a wealth of indigenous knowledge that needs to be exploited. The plants used to treat dysmenorrhea for example may be important analgesic agents that need further investigation while those with anti-fertility properties may contain steroidal phyto chemical compounds. Such species therefore need further investigation to establish their efficacy and mechanism of action.

The toxicity of aristolochic acid (ArA) has attracted considerable attention since the case of nephropathy regarding diet pill preparations was reported. The present study was performed to determine the reproductive toxicity of ArA in female SD rats. ArA was administered orally to female rats at 2, 8 or 16 mg/kg b.w./day and the females were mated with untreated males and their reproductive status was determined. ArA is well known as PLA2 inhibitor, toxic effects of such a relationship are not yet clear, and in vivo study on this matter are scarce. For this study, ArA was administered to pregnant rats at 10 or 20 mg/kg b.w./day, because premating treatments were not conducted. Administration of 20 mg/kg b.w./day caused infertility or abortion. In ArA-treated groups, PGF2a productions were inhibited and apoptosis were suppressed. Collectively, this study may help to further define the roles of sPLA2 in reproductive organs and to determine the toxic mechanisms of ArA.

Chronic and unpredictable stress can disrupt the female reproductive system by suppression for secretion of gonadotrophin-releasing hormone (GnRH) and gonadotrophin, resulted in ovarian malfunction and infertility. In the recent days, kisspeptin has been highly highlighted as a hypothalamic peptide which directly stimulates synthesis and release for GnRH. However, in spite of the key role of kisspeptin in the female reproductive system, little information is still available on the changes of its expression during ovarian cycle under stressed condition. Therefore, we induced chronic and unpredictable stress series to the female mice to analyze kisspeptin expression in the brain and ovary. Stressed mice exhibited changes of behavior and body weight gain during the stress assessment, which suggested that the present stress model in mice was successfully established. In the brain level, kisspeptin expression was attenuated than control. In the ovary level, the stressed mice displayed irregularly shrunk oocytes with broken zona pellucida throughout the follicle stages, pyknotic granulosa cells, decreased number of developing follicles and increased number of atretic follicles than the control. In case of kisspeptin expression in the whole ovary tissue, the expression level was decreased in the stressed mice. In detail, the less intensity of kisspeptin expression in the antral follicles phase was observed in the stressed mice than control mice, indicating that local function of kisspeptin during ovary cycle is highly associated with development of ovarian follicles. We expect that the present study has important implications for the fields of reproductive biology.
