Introduction: The reason of infertility can have a direct influence on the plan and outcome of management. In this paper we intend to show the effect of tuberculosis (TB) history on female infertility among infertile couples attending to Rooyan infertility management center. Materials and methods: In this case-control study our cases were those who were diagnosed as infertile female and controls were those women whose husbands were infertile due to some male factor. We used logestic regression for analyzing the association of history of Tuberculosis and female infertility with attributable risk estimation. Results: 308 cases were compared to 314 controls. Considering the odds ratio and its 95% confidence interval, there was a significant difference between the history of TB and infertility (OR=4.7, 95% CI: 1.01-29.91). The attributable risk of TB for female infertility was 0.023±0.01 (which is significant at 5% level). Conclusion: These figures show that at least 2% of female infertility can be prevented by prevention and proper treatment of tuberculosis.

Background and Aim: Resistance training with blood flow restriction can have the same effects as traditional resistance training. The current study aimed to determine the effect of six weeks of selected resistance training with active and passive rest, with and without blood flow restriction, on young men’s C Reactive Protein (CRP), Lactate Dehydrogenase (LDH), and muscle endurance.
Methods & Materials: From the available and voluntary samples, 24 healthy young soldiers of the Islamic Republic of Iran Air Force were divided into 3 groups of 8 subjects: traditional resistance training, resistance training with blood flow restriction, and passive rest and resistance training with blood flow restriction and active rest. Exercise programs were performed for 6 weeks, 3 sessions per week with an intensity of 70-80% One-repetition maximum (1RM) for the traditional resistance group (3 sets of 10), 20-30% 1RM for the passive rest group (30-15-15-15), and 20 -30% 1RM was administered for the active rest group (30-7-15-7-15). Before and after six weeks, physiological and anthropometric characteristics, muscle endurance, and hormonal levels were measured, and ELISA measured blood samples. Data were analyzed using covariance and Bonferroni post hoc tests and paired t-test for comparison within groups.
Ethical Considerations: All experimental procedures were approved by the Ethics committee of the Sport Sciences Research Institute of Iran (Code: I.R.SSRC.REC.1398.129), Clinical Trial (Code: ID IRCT20191207045644N1) from the Iran Clinical Trial Registration Center and were conducted under the Declaration of Helsinki.
Results: Results showed that 6 weeks of exercise had a significant effect on Muscle endurance (P=0.001) but on the levels of C-reactive protein (P=0.43) and Lactate dehydrogenase (P=0.44) had no significant difference. 
Conclusion: According to the results of this study, it seems that a combination of resistance training with restriction of blood flow and Interval training (active rest) can be a good alternative to traditional training and, in some cases, replace resistance training with occlusion and passive rest.
