Objective: To Evaluate PREGNANCY RATE in synchronized dairy herd by Selectsynch procedure and PG.Design: Experimental study.Animals: Three hundred and seventy four dairy cows were randomly allocated to three groups: selectsynch, synchronized with PG and spontaneous heat.Procedure: All cows were cleaned at day 30 after parturition and allocated to the following groups: synchronization by select synch-insemination (n=139), synchronization by PG-insemination (n=125) and natural heat-insemination (n=110). PREGNANCY was diagnosed at days 42-50 after insemination.Statistical analysis: Chi-square test.Results: For these methods PREGNANCY RATE were54 percent, 44.8 percent and 46.4 percent, respectively. Moreover there were not any significant difference among them.Clinical implications: Since selectsynch made an acceptable PREGNANCY, it can be recommended for dairy herds.

Background: Infertility not only as a disease but also as a serious problem affects the family and harms its health.Approximately 50 to 80 million people in the world suffer from infertility. Laparoscopy is a golden standard which helps diagnose peritoneal and the fallopian tubal problems and treat them.Materials and Methods: In this cross-sectional study, 162 infertile women referring to the Honari Clinic of Jahrom, Iran from 2008 to 2010 were enrolled. Laparoscopy was applied for these women due to other unsuccessful treatments. Information was collected from medical documents and analyzed by SPSS 11.5.Results: With the mean age of 27.2±5.31years, 95.7% of the cases had their first marriage, 80.2% had primary infertility, and 93.8% were housewives. The result of hysterosalpingography revealed normal fallopian tubes in 126 cases (77.8%). Of all the cases 18.5% had had unsuccessful intra-uterine injection of sperm. According to the laparoscopic findings and evaluation of ovarian problems, the causes of infertility included 66% ovarian cysts, 4.3% adhesions, 9.9% endometrioses. Also, the evaluation of the fallopian tubes showed 77.8% open tubes and 22.2% closed ones. The RATE of PREGNANCY after laparoscopic surgery was 54.9%, most of which (84.6%) had been after cauterization of polycystic ovaries.All of these pregnancies had been spontaneous, of which 83.15% had led to termination and 16.85% had ended in abortion. None of the cases had had ectopic PREGNANCY or any other problem.Conclusion: The most common cause of women's infertility in Jahrom is polycystic ovaries, which in most cases is fortunately treated after laparoscopy. Hence cauterization of ovaries by laparoscopy can be an effective treatment for infertility.

Introduction: Is there any differences between the PREGNANCY RATE of frozen-thawed embryo transfer (FET) in agonist and antagonist protocols. The aim of this study was to assess the effect of gonadotropin-releasing hormone (GnRH) antagonists/buserelin on embryos by comparing the outcome of cryopreserved-thawed embryo transfers for cycles using a GnRH agonist or GnRH antagonist/buserelin protocol for the controlled ovarian stimulation in the oocyte retrieval cycle.Materials and Methods: We studied the frozen embryos from 80 women undergoing ICSI which were administered either HCG/GnRH agonist long protocol (Group A, n=52) or GnRH/buserelin antagonist protocol (Group B, n=18) that were thawed in Novin Infertility Center (Mashhad, Iran) from March 2010 to June 2010 (there were no significant statistically differences between two groups in the age and male factor). Frozen embryo transfer PREGNANCY RATE of these two groups were evaluated. Data analyzed by Fisher test (SPSS version 7).Results: PREGNANCY RATEs were similar independent of whether they resulted from the long-protocol cycles with HCG (46.2%) or from the antagonist protocol cycles with buserelin (38.9%).Conclusion: Frozen-thawed embryo derived from the GnRH agonist cycles have the same PREGNANCY RATEs to those derived from the GnRH/buserelin antagonist cycles, Furthermore, in fresh embryo, lower PREGNANCY RATEs following GnRH/buserelin-antagonist protocols compared with long GnRH/agonist protocols have been reported, The differences might be due to an impact on oocyte number and quality or on the endometrium, not embryos quality, so according to this point in the patient with the risk of OHSS who received GnRH/buserelin antagonist protocol, it would be better to freeze all the embryos and then transfer them in a better situation.

Infertility is one of the social problems all over the world included our country. One of the treatable causes of infertility is an ovarian diseases like polycstic ovary syndrom (PCOS). The first line of treatment of women with polycystic ovary syndrom (PCOS) and women who are resistant to clomid and gonadotropin is to use the standardized techniqe of Laparoscopic ovariain drilling with unipolar forceps cautery. The purpose of this research was to evaluate the reproductivity outcome of infertile women with PCOS in jahrom city. In this retrospective study, e evaluated a consecutive series of 40 - cases of PCO related unovulatory infertility treated with Laparoscopic ovarian drilling between march 1999 and September 2001. In all of these cases PCOS was demonstRATEd by using sonography, hormaonal profile and menstural history. All of them were resistand to maximum dose of clomid (200 mg/day) and some of them did not response to HMG. Ovulatory RATE, PREGNANCY RATE and miscarriage RATE were obtained. Evaluation of menstural history and basal body temperature after surgical operation showed the ovulation with regular cycle in 35 women (87.5%), 17 women conceived after 1-2 years of surgery (42.5%) and two cases had abortion (11.7%). In general the results of this research showed that Laparoscopic ovarian drilling is an effective alternative treatment in clomid resistant infertile women with PCOS.

Background: The current study is to evaluate cardiovascular effects of anesthetic medications and volatile anesthetics on cardiac stress using cardiac stress index (CSI) and RATE pressure product (RPP) and to determine which of them in useful in evaluating cardiac stress after comparing results obtained from each method.Materials and methods: 40 patients, 60-80 years old, who were all performed trans abdominal prostatectomy were studied. Patients were divided into two groups, half of patients were placed in group A and the other half in group B. The study was carried out as a blinded study. CSI was measured and evaluated in group A and RPP changes were studied in group B.Results: The mean CSI were 60.25±5.57, 63.05±5.54, 55.75±4.78 and 67.65±4.88 before anesthesia induction, after induction, before surgical incision and in recovery respectively. There was no meaningful difference.RPP mean in four above mentioned stages was 10.15±0.44, 9.9±0.69, 6.8±0.36 and 9.2±0.61 respectively. There was a meaningful difference between RPP in stages before anesthesia induction and before surgical incision (P<0.0001).Conclusion: Considering the obtained results from this study, it can be seen that even in noncardiac surgery, the stress level is high in patients in the stage before surgery. This figure was not clear in RPP index case and was not in accordance with CSI, which means CSI has been able to illustRATE existing stress level better and efficiently.

Background: Assisted hatching techniques are utilized to facilitate the embryo escape out of the zona pellucida and increase the PREGNANCY RATEs in IVF centers. The objective of this study was to evaluate if assisted hatching improved the RATEs of PREGNANCY for in-vitro fertilization, in Isfahan Infertility Center.Materials and methods: This case-control study was carried out on 296 infertile patients. Patients with assisted hatching were 131 (case group) and non-treated patients were 165 (control group). Patients' age, number of oocytes aspiRATEd, number of oocytes fertilized, and numbers of embryos transferred were matched. The PREGNANCY was determined by positive b-HCG, 14 days after transfer; and implantation was defined as presence of gestational sac in uterus on sonography. Statistical analysis was done with the student t-test and X2 test. A Pvalue of less than 0.05 was considered statistically significant.Results: No significant difference was noted in the mean age of patients, the number of oocytes aspiRATEd, the number of oocytes fertilized, and the number of embryos transferred between the case and control groups. In addition, no significant difference was observed in the RATEs of PREGNANCY between the hatched and control groups (22.9% versus 20.6%, respectively).Conclusion: Assisted hatching has no significant impact on PREGNANCY RATEs in the patients population studied. Further data are needed to determine if assisted hatching has beneficial effect on PREGNANCY RATE.

Introduction: The usefulness of ultrasound determination of endometrial thickness and pattern in PREGNANCY prediction is a matter of controversy. The present study attempts to clarify this controversial issue more. Materials and Methods: 1030 infertile couples with ovulatory factor infertility who had undergone one cycle of ovulation induction were included in this study. All patient charts were reviewed for endometrial thickness (<7, 7-14, >14 mm) and pattern (trilinear vs. homogenous) on the time of hCG administration. Age, duration of infertility, and number of follicles were evaluated in all patients. Clinical PREGNANCY RATE was considered as the desired treatment outcome. The SPSS 10 software and chi-Square t-test were used for statistical analysis, and P<0.05 was defined as statistical significance. Results: The overall PREGNANCY RATE was 25.8% (266 out of 1030). There was no significant difference in PREGNANCY RATEs in three groups of endometrial thickness, nor in two groups of endometrial pattern. Conclusion: This study failed to show any significant relationship between endometrial thickness and pattern, and PREGNANCY RATE. Further studies are recommended

Introduction: One of the causes of infertility is due to male factors (Sperm count, sperm motility and morphology). Male factor infertility may be due to disorders in the number of spermatozoa, sperm motility or sperm morphology. Intrauterine insemination (IUI) is routinely used to help couples with male factor infertility. The criteria used to evaluate semen quality include sperm concentration, sperm motility and the percentage of sperm with normal morpho-logy. Several studies have been done on motility and sperm concentration but few studies have been done on sperm morphology. In this study, we evaluated IUI success RATEs in normal sperm morphologies that were greater or fewer than 5% in the Northern part of Iran (Mazandaran(.Materials & Methods: This analytical study was performed on patients referred to two infertility centers in Babol after ovulation induction. After collecting sperm specimens from the cases, the samples were kept in sterile tubes and then they were washed and swum up before performing IUIs. Sperm concentration, motility and morphology were evaluated according to NAFA and ESHRE-SIGA criteria (2002). Statistical analysis was done by SPSS software using logistic regression, paired t-tests and Fisher’s exact test. A p–value < 0.05 was considered significant.Results: Out of 561 patients, IUIs were successful in 103 (20.2%) patients with normal sperm morphology greater than 5% and in 4 (7.7%) patients with normal sperm morphology fewer than 5%; the difference being statistically significant (p<0.05). In 504 cases with sperm concentrations greater than 20 million/ml, IUI success RATEs in subjects with normal sperm morphology greater than 5 % were significantly higher than cases with normal sperm morphology fewer than 5% (21.4:5.6), (p<0.01). In 543 cases with sperm motility greater than 50%, IUI success RATEs were significantly higher in patients with normal sperm morphology greater than 5% compared to the cases with normal sperm morphology fewer than 5% (20.5:8.3), (p<0.05(.Conclusion: It seems that normal sperm morphology >5% is an important and effective factor in IUI outcomes and normal sperm morphology, alongside sperm counts and normal motility, has an essential role in increasing PREGNANCY RATEs. Therefore, it is suggested that in addition to sperm counts and motility, evaluations of sperm morphology be included in the work up too.
