Background: Chromosomal disorders are the most common cause of first trimester spontaneous abortion. Among the human chromosomes, chromosome no.9 was the most common structural chromosomal variant and it is not thought to be of any functional importance, which often considers as a normal variation in structural polymorphisms, nevertheless there are some studies which claim that there is an association between heteromorphism of chromosome no.9 and some pregnancy complication.
Case: To postulate any correlation between chromosome no. 9 heteromorphism and recurrent abortion, chromosomal analysis was performed on the basis of G-banding technique at high resolution for a couple with the history of 4 ultrasound diagnosed blighted ovum and Chromosome constitution appeared with chromosome no.9 heteromorphism in all 30 metaphases screened for both partners (9p11-q13).
Conclusion: Observation of reproductive failure in couples with heteromorohic pattern of chromosome no.9 suggests that, although the heteromorphism of chromosome no.9 is not a rare condition which often consider as a normal variation with no evidence of any phenotypic effect of patient, nevertheless it seems as if the location of heteromorphic region maybe interfere with meiotic events like the phenomenon of crossing over or miotic segregation of fertilized egg that eventually lead to the development of fertilized eggs with chromosomal abnormalities leading to the possibility of anemberyonic pregnancy, therefore chromosomal analysis for detecting of chromosome no.9 heteromorphism for couples with the history of ultrasound diagnosed blighted ovum will be strongly suggested.

Background: Approximately 205 million pregnancies occur each year in the worldwide. On the other hand, Spontaneous abortion has been reported in 15-20% of all diagnosed pregnancies. The most common cause of spontaneous abortion is chromosomal abnormalities of the embryo. Robertsonian translocation carriers specially 21-14 are the most common balanced rearrangement among the carrier couples with the history of spontaneous abortion. In order to search for balanced chromosomal rearrangement and cytogenetic disorders, 10 members of related family with consanguinity marriage with the history of recurrent miscarriage were assessed.
Case: Cytogenetic evaluation on the basis G-banding technique at high resolution was performed in 3 couples and their related family with the history of idiopathic RSA in order to postulate any balanced chromosomal rearrangement.
Conclusion: six members of them appeared with robertsonian balanced translocation between chromosome No.21 to No. 14 with the karyotype of 45, XX, t (14, 21) and 45, XY, t (14, 21), which this results are in agreement with several similar works which claimed that the risk of spontaneous abortion in couples with balanced chromosomal rearrangements is higher compared with general population. Considering to results of present study, it seems as if the cytogenetic analysis of couples with the history of recurrent abortions should be suggested compulsory to estimate the probable presence of any chromosomal rearrangement. This offer wills valuable information for genetic consulting.

Background: Male hypogonadism is associated with type II diabetes mellitus due to testicular dysfunction. Medicinal plants have received considerable attention for the management of diabetes and its complications.
Objective: The aim of present study was to evaluate the anti-diabetic and protective influence of Crocin on testopathy in diabetic rats.
Materials and Methods: In this experimental study, type II of diabetes mellitus was induced by high-fat diet and low dose of streptozotocin. Male Wistar rats (8 weeks,150–200 gr, 18 rats; n= 6 per group) were divided into a control group (standard diet), diabetic group (streptozotocin+high-fat diet), and treatment group (High-fat diet+streptozotocin+Crocin at 20 mg/kg/day, i.p. for 60 days). After 60 days, animals were euthanized, testis and epididymis were dissected, and weights of testes and sperm count were analyzed. Hematoxylin-eosin-stained was done for histopathological examination. Blood samples were collected for the assessment of serum glucose and cholesterol.
Results: High-fat diet and streptozotocin significantly increased the serum glucose and cholesterol levels as compared to the control group (p≤ 0. 001). Moreover, there was a significant decrease in the weight of right (p= 0.008) and left testes (p≤ 0.001) and also the total sperm count (p= 0.023) in the diabetic group compared with the control group. Current results also identified that type II diabetes mellitus induced degeneration in the morphology of seminiferous tubules. Application of Crocin couldsignificantly decrease serum glucose and cholesterol levels (p= 0.003). Furthermore, Crocin treatment significantly increased the weight of the right (p= 0.026) and left (p= 0.014) testes and total sperm count (p= 0.000). Also, Crocin could attenuate the
pathological changes of the testes in the treatment group.
Conclusion: Present findings concluded that Crocin treatment improved diabetic testopathy and impairment of seminiferous tubules induced by high-fat diet and streptozotocin.
