background: the initial step in the diagnostic investigation of male infertility has been traditionally based on the conventional seminal profile. however, there are significant limitations regarding its ability to determine the underlying mechanisms that cause the disorder. sperm dna fragmentation has emerged as a potential causative factor of reproductive failure and its assessment has been s...

Rapid development in assisted reproductive techniques along with relieving the pain of childlessness has brought new ethical and policy dilemmas. Posthumous assisted reproduction is the most challenging, difficult and sensitive issue to be discussed ethically and religiously. In this paper the acceptability of the posthumous reproduction in Islamic contexts is evaluated and major concerns like ...

Background: Cigarette smoke contains many oxidants and may alter the human reproduction by inducing oxidative stress (OS) in both active and passive smokers. This study was designed to evaluation the effect of environment tobacco smoke (ETS) exposure on oxidative stress in follicular follicle and assisted reproduction outcomes. Materials and Methods: A prospective study was carried out on 236 i...

Background: To examine the relative contributions of dietary fat intake level and its food sources and assisted reproduction parameters. Materials and Methods: A prospective study was conducted on 240 infertile women. In assisted reproduction treatment cycle, body mass index (BMI), physical activity (PA), calorie intake, fat consumption and major food sources were assessed. The number of retrie...
