Background: Hops Plant (Humulus lupulus L.) plants is very beneficial has many industrial and medical applications. hops has protein, amino acids, lipids, fatty acids, sugars such as glucose and fructose, pectin, salts, wax and estrogenic compounds. So the aim of this study was to evaluate the effect of hops extracts on hormone levels and sex cells in adult mice. Materials and Methods: 40 adult...

Background: There is a great concern for the possible adverse effects of cell phones and noise waves and it looks these wave effects on the individuals’ health. Thus, the present study was conducted to examine the effect of cell phone waves, severity noise, and simultaneous effect of cell phone waves and severity noise on sperm motility and sexual hormones in adult male rats. Materials and Meth...

In this paper, we investigate the coevolution of diploid sexual reproduction and cell senescence (i.e., cell aging). We use probability analysis, computer simulation, and exact numerical computation to analyze the impacts of deleterious recessive mutations on sexual and asexual reproduction. The main conclusion is that, without cell senescence, the evolutionary advantages of sexual reproduction...

Background: More than a decade work in preservation of male fertility by spermatogonial stem cell (SSC) transplantation in animal models as well as new discoveries about the nature of human SSCs has prompted an investigation into the possibility of an effective clinicalgrade procedure for isolation and cryopreservation of human testicular cells. Materials and Methods: Clinical-grade reagents, v...

the issues that arise in this articles are the causes and the bases of social - and sexual - devience according to a sociological point of view. then a search through a number of 350 files of sexual - crimes in babol, declares the causes on a sociological point of view, cultural transmission & contrast theory. in assessment during this research regarding age, sex & occupation as the main criter...

Plants have the remarkable ability to establish new cell fates throughout their life cycle, in contrast to most animals that define all cell lineages during embryogenesis. This ability is exemplified during sexual reproduction in flowering plants where novel cell types are generated in floral tissues of the adult plant during sporogenesis, gametogenesis, and embryogenesis. While the molecular a...

PURPOSE/OBJECTIVES To examine changes in sexual functioning during treatment for lung cancer and the extent to which age, gender, social support, and mood status affect sexual dysfunction. DESIGN Prospective, exploratory. SETTING Outpatient cancer clinic. SAMPLE 59 of 84 eligible patients diagnosed with small cell or non-small cell lung cancer. METHODS The Derogatis Interview for Sexual...
