[Comparison of the effects of Myo-inositol alone or in combination with MEM vitamins on embryo development in Sanjabi Sheep]

The objective of this study was to evaluate the effects of myo-inositol alone or in combination with MEM vitamins on embryo development in sanjabi sheep. Sheep Cumulus Oocytes Complexes [COCs] were matured in vitro at 39 °C, in humidified 5% CO2 atmosphere for 22-24 h. There were three treatments, culture in synthetic oviductal fluid medium [treatment I], culture in synthetic oviductal fluid medium supplemented with1 x MEM vitamins [treatment II], culture in synthetic oviductal fluid medium supplemented with myo-inositol [treatment III], COCs were then fertilized and cultured in vitro for and days when the ratios of in vitro embryo development of the hatched blastocysts were assessed and compared with the control group. The presence of myo-inpsitol significantly improved overall morula rates [34.39%] than that of control group [24.18%], but there was no difference between myo-inositol and 1 x MEM vitamins in the percentage of embryos successfully developing to the morula stage [p<0.05]. The addition of myo-inositol improved the mean blastocyst formation compared to the oocytes matured in medium containing no MEM [control] or 1 x MEM vitamins [32.63, 13.96 and 21.06% respectively]. However, the mean percentage of cleavage rate was not substantialy different between treatments. These results suggest that adding myo-inositol to SOF medium be more beneficial for subsequent sheep embryonic development

[ assessment of sonohysterography as a diagnostic tool for uterine cavity defects and tubal patency]

In a prospective blind study, we evaluated Sonohysterography [SHG] as a diagnostic tool for uterine cavity and tubal patency and compare SHG with laparoscopy in tubal patency and hysterosalpyngography for Uterine anomaly as gold standard methods. 76 infertile patients undergone SHG and HSG and laparoscopy and comparison between the different diagnostic techniques for the evaluation of the uterine cavity and tubes was carried out. In comparison between SHG and HSG in the evaluation of uterine cavity, the sensivity of SHG for uterine anomalies was 50% and its specificity was 86.95%. In comparison between SHG and laparoscopy in evaluating tubal patency, specificity of SHG was 81.29% and its sensivity was 28.57%. Sonohysterography can be considered as a reliable and accurate method in the first line of evaluation of uterine cavity and tubal patency in infertile patients before HSG, Hysteroscopy, laparoscopy and the all of patients with history of failed IVF
