Background: Different studies show that chromosomal balance translocation in the parents can cause recurrent spontaneous abortions. Incidence of chromosomal translocation abnormalities in couples with repeated abortions is from 0% to 31%.
Objective: The purpose of this research was studying the presence or absence of chromosomal abnormalities and heteromorphism in couples with recurrent abortions and also the role of this anomaly in the abortions.
Materials and Methods: This study is a cross sectional descriptive study which have investigated 75 couples who had three abortions or more, and 65 couples who had two abortions that referred by gynecologist to the lab of Beheshti Hospital in Hamedan for cytogenetical investigation. Also 40 healthy individuals without history of abortion investigated as control group.GTG bonding technique (staining banding with gymsa and trypsin) is used in this study.
Results: Frequency of chromosomal abnormalities and heteromorphism among couples with three or more abortions were reported respectively 5.3% and 9.3%. This frequency in couples with two abortions was respectively 3.07%and 6.15%. The frequency of chromosomal heteromorphism in control group was 7.5% and no chromosomal abnormalities were observed in them.
Conclusion: This study shows that chromosomal abnormality can be one reason of recurrent spontaneous abortions and more abortion increases the probability of this anomaly. Also, existence of chromosomal heteromorphism in the general population without clinical abortion symptoms shows that chromosomal heteromorphism cannot be the reason of these spontaneous abortions.

Background: Diabetes has an adverse effect on spermatogenesis by rising oxidative stress.
Objective: The aim of this study was to investigate the effect of Teucrium Polium extract administration on spermatogenesis and testicular structure in diabetic rats induced with Streptozotocin.
Materials and Methods: 32 male Wistar rats were randomly divided into four groups (n=8/each): control group, diabetic group received distilled water, and two experimental groups included diabetic rats treated with 50 and 100 mg/body weigh of Teucrium Polium extract for 6 six weeks. After six weeks, the left testis had been removed and the morphometrical study was performed. Blood samples were collected from the ophthalmic veins of the rats and plasma levels of glucose and testosterone hormone were measured afterward.
Results: The reduction in diameters of the seminiferous tubules and thickening ofthe wall of the seminiferous tubules (p=0.05) were seen in diabetic rats. Also, thedegenerative changes in cells arrangement have been observed. Statistical analysisshowed the use of Teucrium Polium significantly improved the above disorders intreatment group (100 mg/BW) in contrast to the non treated diabetic group (p=0.05),but no significant difference was seen between the experimental group treated with50 mg/BW of Teucrium polium and diabetic group (p=0.08). These data alsorevealed that treatment of diabetic rats with 100 mg/BW of Teucrium Polium extractsignificantly improves the change in serum glucose (p=0.001) and testosterone(p=0.03).
Conclusion: The results of the present study indicate that diabetes produces degenerative changes in the testis of rats and administration of Teucrium polium reduces complications resulted from diabetes.

Background: Selection of the best embryo for transfer is very important in assistedreproductive technology (ART). Using morphological assessment for this selectiondemonstrated that the correlation between embryo morphology and implantationpotential is relatively weak. On the other hand, aneuploidy is a key genetic factorthat can influence human reproductive success in ART.
Objective: The aim of this lab trial study was to evaluate the incidence ofaneuploidies in five chromosomes in the morphologically high-quality embryosfrom young patients undergoing ART for sex selection.
Materials and Methods: A total of 97 high quality embryos from 23 women at theage of 37or younger years that had previously undergone preimplantation geneticscreening for sex selection were included in this study. After washing, the slides ofblastomeres from embryos of patients were reanalyzed by fluorescence in-situhybridization for chromosomes 13, 18 and 21.
Results: There was a significant rate of aneuploidy determination in the embryosusing preimplantation genetic screening for both sex and three evaluated autosomalchromosomes compared to preimplantation genetic screening for only sexchromosomes (62.9% vs. 24.7%, p=0.000). The most frequent detectedchromosomal aneuploidy was trisomy or monosomy of chromosome 13.
Conclusion: There is considerable numbers of chromosomal abnormalities inembryos generated in vitro which cause in vitro fertilization failure and it seems thatmorphological characterization of embryos is not a suitable method for choosing theembryos without these abnormalities.
