Objective: To compare the clinical outcomes of ICSI with sperm retrieved from testicular tissue in patients with obstructive azoospermia (OA) or hypospermatogenesis (HS). Methods: From January 2003 through December 2006, 155 patients with OA (241 cycles) and 28 patients with HS (34 cycles) were included in this study. We compared clinical outcomes of ICSI with testicular sperm such as fertilization rate, implantation rate, clinical pregnancy rate and delivery rate. Data were statistically analyzed using t-test and ${\chi}^2$-test. Results: Testicular spermatozoa could not be retrieved in 1 out of the 21 cycles where fresh testicular sperm extraction in HS patients. Fertilization rate (FR) was significantly higher in OA than HS (75.6 % vs. 62.6%, p<0.001). Cleavage rate (CR) per fertilized zygote was also significantly higher in OA than that in HS (66.8% vs. 54.8% p<0.001). However, there were no significant differences in good embryo rate (GER), clinical pregnancy rate (CPR), implantation rate (IR) and delivery rate (DR). Conclusion: Our results show that testicular sperm of HS does not affect CPR, IR, and DR although it has shown reduced FR and CR.

Background: Polycystic ovary syndrome (PCOS) is a combination of chronic anovulation, obesity, and hyperandrogenism and can affect sexual function in women of reproductive age. It is also associated with endometrial cancer. Our aim was to evaluate the frequency and predisposing factors of sexual dysfunction in PCOS patients. Materials and Methods: In this cross-sectional study, 16 married women with a definite diagnosis of PCOS were recruited. Sexual function was assessed in the domains of desire, arousal, lubrication, orgasm, satisfaction and pain using the female sexual function index (FSFI) questionnaire. Patients were also assessed for mental health using the depression, anxiety and stress (DASS-21) questionnaire. Presence of hirsutism was assessed using the Ferriman-Gallwey (FG) scoring system. Demographic data were obtained from patients during in-person interview. Results: Sexual dysfunction was present in 62.5% of patients with the domains of arousal and lubrication particularly affected (93.8% and 87.5%, respectively). Patients with symptoms of depression and anxiety were significantly more likely to suffer sexual dysfunction than those without these symptoms (p=0.04 and p=0.03 respectively). Patients with stress symptoms reported higher orgasm dysfunction than those without (p=0.02). No significant difference in any of the FSFI score domains was observed between patients with and without hirsutism. Conclusions: PCOS patients markedly suffer from sexual dysfunction and therefore it seems appropriate to be screened for intervention. Poor mental health conditions that may be the result of infertility or other complications of PCOS should also be considered as curable causes of sexual dysfunction in these patients.

Subzonal insemination(SUZI) has been proposed for patients with severe male factor and previous fertilization failure. However, very low fertilization rates still persisted. The aims of this study were firstly, to examine the relationships between the fertilization rate and sperm parmeters, sperm incubation media and time, secondly, to evaluate the outcome of 119 cycles of SUZI applied the modified sperm preparation method. The fertilization rates were influenced more sensitively by sperm preincubation media and time than by sperm parameters. According to preincubation media and time, the fertilization rates were 43.3% in 50% follicular fluid (HFF), 36.6% in 10% fetal cord serum(FCS), and with the time, increased in FCS, but decreased in HFF. In regrd with sperm parameters, the fertilization rates were 42.9% in normal and 37.6% in subnormal group. The best results were obtained from SUZI by the spermatozoa incubated in 50% HFF for 6-8 hours. So we tried 119 cycles of SUZI(normal; 39 cycles, subnormal; 80 cycles) using the preparation method of 6-8 hour incubation in 50% HFF. There were no signigicant differences in the fertilization rates between normal(125/269, 46.4%) and subnormal sperm(264/635, 41.6%). Contrary to the fertilization rates, pregnancy outcomes were different between both groups. Better results obtained from the subnormal group than the normal in the number of transferred embryos, that of good embryos, and developmental rate of the fertilized eggs. The pregnancy rates per transfer were totally 13.3%(13/98),20.0%(13/65) in subnormal group. In the normal group, 2 patients showed ${\beta}$-hCG positive, but resulted in chemical pregnancy. Of 13 clinical pregnancies, two aborted, 6 on-going, and 5 delivered. In conclusion, SUZI is an effective technique to overcome fertilization failure for male factor and unexplained. The fertilization rate is influenced by sperm parameters, sperm incubation media and time. Also the quality of oocytes might be important for pregnancy as same as that of sperm.

Anti-phospholipid antihodies (aPL) have important roles in various pregnancy complications such as recurrent miscarrige, growth retardation, placental abruption and stillbirth. However, their biological actions on preimplantation development of oocytes are still unclear. In this study, we investigated whether either aPL containing sera or phospholipids could affect in vitro fertilization and development of mouse oocytes. Sera used in this study were collected from three patients and the presence of aPL in the sera was confirmed by enzymatic-linked immunosorbent assay. When mouse oocytes were cultured in a serum-free, Chatot, Ziomek and Bavister (CZB) medium (Experiment 1), addition of aPL-containing sera (10%) to CZB medium did not. significantly (P>0.05) influence sperm penetration of oocytes. However, development to the blastocyst stage was significantly (P<0.05) inhibited by serum addition, and formation of morulae (16-23% vs. 58%) and blastocysts (0-4% vs. 21%) was markedly reduced compared with no addition (Experiment 2). In Experiment 3, pronuclear stage embryos were cultured for 96 h in GZB medium supplemented with 1 $\mu$g /ml phosphatidyl ethanolamine, 1 $\mu$g/ml phosphatidyl inositol or 1 $\mu$g /ml phosphatidyl choline. No increase in embryo development was found after addition of the phospholipids to CZB medium. These results suggest that 1) aPL have an inhibitory role in preimplantation development of mouse embryos, and that 2) the action of aPL may be related to a specific phospholid (s) rather than the tested phospholipids in the present study.

Objective: The aim of this study was to investigate whether anti-M$\ddot{u}$llerian hormone (AMH) levels could be predict ovarian poor/hyper response and IVF cycle outcome. Methods: Between May 2010 and January 2011, serum AMH levels were evaluated with retrospective analysis. Three hundred seventy infertile women undergoing 461 IVF cycles between the ages of 20 and 42 were studied. We defined the poor response as the number of oocytes retrieved was equal or less than 3, and the hyper response as more than 25 oocytes retrieved. Serum AMH was measured by commercial enzymelinked immunoassay. Results: The number of oocytes retrieved was more correlated with the serum AMH level (r=0.781, $p$ <0.01) than serum FSH (r=-0.412, $p$ <0.01). The cut-off value of serum AMH levels for poor response was 1.05 ng/mL (receiver operating characteristic [ROC] curves/area under the curve [AUC], $ROC_{AUC}$=0.85, sensitivity 74%, specificity 87%). Hyper response cut-off value was 3.55 ng/mL $ROC_{AUC}$=0.91, sensitivity 94%, specificity 81%). When the study group was divided according to the serum AMH levels (low: <1.05 ng/mL, middle: 1.05 ng/mL - 3.55 ng/mL, high: >3.55 ng/mL), the groups showed no statistical differences in mature oocyte rates (71.6% vs. 76.5% vs. 74.8%) or fertilization rates (76.9% vs. 76.6% vs. 73.8%), but showed significant differences in clinical pregnancy rates (21.7% vs. 24.1% vs. 40.8%, $p$=0.017). Conclusion: The serum AMH level can be used to predict the number of oocytes retrieved in patients, distinguishing poor and high responders.

Background: The Prostate cancer is the 2nd most common cancer worldwide for males, and the 5th most common cancer overall, with an estimated 900,000 new cases diagnosed in 2008 (14% of the total in males and 7% of the total overall) aim of this study was to assess some of the most proposed environmental factors influencing the incidence of prostate cancer among Iranian men. Smoking, opioids, occupation and living location were considered as studied risk factors of the prostate cancer in this research. Material and methods: Two groups of affected men with prostate cancer and controls aged 50-75 years referred to medical clinics were subjects in this case-control study. Living and working place, smoking and drug consuming habits were assessed for any associations with prostate cancer. Results: The largest number, of patients, in order, belonged to Tehran, provincial capitals, major industrial cities, small towns and villages, respectively. The disease showed links with smoking and drugs with a significant difference between controls and patients (P value <0.0001). Conclusions: Our recent evidence duplicates previously done researches confirming the serious adverse effects of smoking and drugs on the prostate cancer occurrence in Iranian men. Living place bearings some hazardous behaviors which increases the rate of diseases as well as advanced chance for associated cancers like prostate.

This study was conducted to identify characteristics observed by staff during infertility treatment, and to analyze the relationship between the result of the treatment according to the ART infertility characteristics. In cooperation with an Obstetrics and Gynecology Hospital in Ulsan, data were collected from 344 people receiving infertility treatment from 2012-1013 and evaluated by cross-analysis, logistic regression analysis, and the ${\chi}^2$ test. Age 30 subjects (72.1%), no disease (70.9%), and no birth children (77.0%) were most common among patients. Causes of infertility factor is the higher the age, followed by uterine factors, ovarian factors were the lower the age.Were assisted reproduction are IUI (51.5%), IVF (23.0%), IUI + IVF (25.6%), assisted reproduction were age (p<.013) infertility period (p<.014), abortion Experience (p<.008) it was not statistically significant. ART pregnancies result was 34.9%, IUI was 49.2%, IVF was 50.8%. The average number of successful IVF treatment was 1.64, while it was 1.36 for IVF. IVF is 0.28 times lower than the IUI. Thus, low in order to increase the success rate of pregnancy according to the assisted reproduction age, nanim period is short, and if you do not have birth children choose artificial fertilization, and high age, IVF If there are nanim period is longer and birth child treatment and you must choose. This study analyzed all subjects who underwent fertility treatment to have research significance. However, it is difficult to generalize, locally called Sun City limits. If this one based on regional and national follow-up study of infertility therapist made it will help to prepare the way of effective treatment for infertility causes.

Objectives: Despite severe oligospermia, males with Y chromosome microdeletion can achieve conception through ICSI (Intracytoplasmic Sperm Injection). However, ICSI may not only result in the transmission of microdeletions but also the expansion of deletion to the offspring. The purpose of this study was to screen vertical transmission, expansion of microdeletions and de novo deletion in male fetuses conceived by ICSI. Materials and Methods: A total of 32 ICSI treated patients with their 33 (a case of twin) male fetuses conceived by ICSI were used to make this study group. Sequence-tagged sites (STSs)-based PCR analyses were performed on genomic DNA isolated from peripheral blood of fathers and from the amniocytes of male fetuses. Ten primer pairs namely, sY134, sY138, MK5, sY152, sY147, sY254, sY255, SPGY1, sY269 and sY158 were used. The samples with deletions were verified at least three times. Results: We detected a frequency of 12.5% (4 of the 32 patients) of microdeletions in ICSI patients. In 4 patients with detected deletions, two patients have proven deletions on single STS marker and their male fetuses have the identical deletion in this region. Another two patients have two and three deletions, but their male fetuses have more than 3 deletions which include deletions to their father's. Meanwhile, seven male fetuses, whose fathers were analyzed to have all 10 STS markers present, have deletions present in at least one or more of the markers. Conclusions: Although the majority of deletions on the Y chromosome are believed to arise de novo, in some cases a deletion has been transmitted from the fertile father to the infertile patient. In other cases the deletion was transmitted through ICSI treatment, it is likely that one sperm cell is injected through the oocyte's cytoplasm and fertilization can be obtained from spermatozoa. Our tests for deletion were determined by PCR and our results show that the ICSI treatment may lead to vertical transmission, expansion and de novo Y chromosome microdeletions in male fetuses. Because the sample group was relatively small, one should be cautious in analyzing these data. However, it is important to counsel infertile couples contemplating ICSI if the male carries Y chromosomal microdeletions.

To evaluate the effectiveness of GnRH agonist for the treatment of uterine myoma as a cause of infertility, fourteen women were recruited to the study. The patients were treated with a delayed-release formulation of D-$Trp^6$-LHRH in biodegradable microcapsules(Decapeptyl-CR), administered intramuscularly at four week intervals for a period of six monthes. The first injection was given on day 21 of the cycle. Serum estradiol levels fell significantly to the mean value of 257.7pgjml 4 weeks after the first injection. Eleven patients in fourteen treated patients had a reduction in the size of uterine myoma as assessed by ultrasonography, two patients had no change of size and one patient had a increase of size. After the first or second injection, all patients became amenorrheic, then resumption of menstruation ocurred at 12 to 14 weeks after the last injection. Common side effects were hot flush, sweating and dyspareunia, whitch were acceptale. In Eleven patients who had a reduction in the size of uterine myoma by treatment with a delayed- release formulation of D-$Trp^6$-LHRH(Decapeptyl-CR), after above treatment with GnRH agonist, then four patients were treated with myomectomy, three patients had pregnancy and full term delivered by Cesarean section. These data suggest that administration of a delayed-release formulation of a GnRH agonist can be a worthwhile and convenient approach to the medical treatment of uterine myoma as a cause of infertility.

Objective: The aim of this study was to report a case series of in vitro matured (IVM) oocyte freezing in gynecologic cancer patients undergoing radical surgery under time constraints as an option for fertility preservation (FP). Methods: Case series report. University-based in vitro fertilization center. Six gynecologic cancer patients who were scheduled to undergo radical surgery the next day were referred for FP. The patients had endometrial (n=2), ovarian (n=3), and double primary endometrial and ovarian (n=1) cancer. Ex vivo retrieval of immature oocytes from macroscopically normal ovarian tissue was followed by mature oocyte freezing after IVM or embryo freezing with intracytoplasmic sperm injection. Results: A total of 53 oocytes were retrieved from five patients, with a mean of 10.6 oocytes per patient. After IVM, a total of 36 mature oocytes were obtained, demonstrating a 67.9% maturation rate. With regard to the ovarian cancer patients, seven IVM oocytes were frozen from patient 3, who had stage IC cancer, whereas one IVM oocyte was frozen from patient 4, who had stage IV cancer despite being of a similar age. With regard to the endometrial cancer patients, 15 IVM oocytes from patient 1 were frozen. Five embryos were frozen after the fertilization of IVM oocytes from patient 6. Conclusion: Immature oocytes can be successfully retrieved ex vivo from macroscopically normal ovarian tissue before radical surgery. IVM oocyte freezing provides a possible FP option in patients with advanced-stage endometrial or ovarian cancer without the risk of cancer cell spillage or time delays.
