Abstract
Background: In 2-4% of couples in fertile ages, recurrent pregnancy loss (RPL) occurs which consisted one out of 300 pregnancies. The aim of this study was to comparison insulin resistance (IR) in patients with RPL to normal individuals.
Materials and Methods: In a case-controlled, prospective study, 49 non-pregnant, non-diabetic women with early RPL as the case group and 49 non-pregnant, non-diabetic women without RPL who had at least one live infant as the control group, and were matched by age, weight, and height, were enrolled. In both groups fasting insulin and glucose levels were measured and insulin resistance, which was defined as a fasting insulin (FI) level ≥20 microU/mL or a fasting glucose to insulin ratio (FGI ratio) of <4.5, was calculated.
Results: The RPL and control groups were similar with respect to age, BMI, fasting glucose levels and glucose to insulin ratios. FI was significantly higher in RPL group than control group (15.20±5.82 vs. 12.23±5.64 microU/mL). Also the frequency of patients with high FI (FI≥20µU/ml) in RPL group was significantly higher than in control group (22.45% vs. 6.12%, Odds Ratio=4.44, Confidence Interval 95%=1.15-17.07). Among the RPL group, 24.49% demonstrated insulin resistance, whereas only 8.16% of the matched controls were insulin resistant (Odds Ratio=3.65, Confidence Interval 95%=1.08-12.26). The RPL and control groups had similar in frequency of low FGI ratio. Also there was no significant difference between mean of FGI ratio in patients with fewer than 12 weeks miscarriage compared to over 12 weeks in RPL group.
Conclusion: Women with RPL have a significantly increased prevalence of insulin resistance when compared with matched fertile controls. It's recommended that in all women with RPL the glucose and insulin measurement should be carried.

Abstract
Background: Recurrent pregnancy loss is a form of infertility with at least three consecutive pregnancy losses or more. Y chromosome microdeletions are a class of most likely genetic factors that occur in a special zone of Y chromosome which is named azoospermia factor region. The purpose of this study was to analyze the presence of Y chromosome complete microdeletions in male partner of couples suffering from idiopathic recurrent pregnancy loss among Iranian population.
Methods: In the present study, Y chromosome microdeletions were evaluated in ninety-two male partners of couples with the experience of recurrent pregnancy loss as the patient group and also a group containing fifty fertile males as the control group. The research has done in Medical Genetic laboratory of Tehran and Islamic Azad University Science and Research Branch, Tehran, Iran within June 2013 to September 2014. The selected sequence tagged site markers (primers) including sY84, sY86, for azoospermia factor a; sY127, sY134, sY129, for azoospermia factor b and sY254, sY255, for azoospermia factor c were used to screen complete microdeletions in Y chromosome. At the first step DNA samples were extracted from all men’s peripheral blood in both patient and control groups and then multiplex polymerase chain reaction and also agarose gel electrophoresis were performed on this DNA samples so as to detect deletions.
Results: With due attention to the data resulted from multiplex polymerase chain reaction and agarose gel electrophoresis in order to recognize Y chromosome micro deletions in azoospermia factor region, in this work, all the bands related to the mentioned primers which were formed during the polymerase chain reaction, were detected on the gel obviously. It means that none of the samples neither the fifty fertile men nor the ninety-two patient men had complete micro deletions in their Y chromosome.
Conclusion: This study suggests that there is no correlation between Y chromosome micro deletions and occurrence of recurrent pregnancy loss in Iranian population.
