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...

reproduction parameters for helicoverpa armigera (hübner) were determined and compared on 13 soybean varieties (dpx, l17, bp, clark, jk, 356, m4, m7, m9, gorgan3, sahar, zane and williams) at 25±1ºc, 65±5% rh over a photoperiod of 16:8 (l:d) hours. reproduction parameters were estimated for individual newly emerged moths, which had spent their immature stages on different soybean varieties. the...

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...

a larger proportion of energy intake for reproduction and also low food availability maydecrease the growth rate of other organs during the late stage of the gonadal development. themain goal of this study is to examine the biological characteristics and organs growth pattern inclupeonella cultriventris during the late stages of gonad development. samples were collectedby capturing 300-350 kilk...

background: high dietary fat consumption may alter oocyte development and embryonic development. this prospective study was conducted to determine the relation between dietary fat consumption level, its food sources and the assisted reproduction parameters. methods: a prospective study was conducted on 240 infertile women. in assisted reproduction treatment cycle, fat consumption and major food...

Our results showed that treatment with both cyclooxygenase (COX1 or COX2) inhibitors impair reproduction parameters of the medaka. Resveratrol (COX1 inhibitor) caused an decrease in the number of spawning females at the first week of feeding fish with experimental diets. In the group treated with NS398 (COX2 inhibitor) we found the lowest sperm velocity parameters and decreased linearity of mov...
