TL;DR: Spermatozoa need small amounts of ROS to acquire the ability of nuclear maturation regulation and condensation to fertilize the oocyte, indicating that oxidative stress is one of the main cause of DNA damage in the germ cells, then there should be good reason for antioxidant therapy in these conditions.
Abstract: Sperm is particularly susceptible to reactive oxygen species (ROS) during critical phases of spermiogenesis. However, the level of seminal ROS is restricted by seminal antioxidants which have beneficial effects on sperm parameters and developmental potentials. Mitochondria and sperm plasma membrane are two major sites of ROS generation in sperm cells. Besides, leukocytes including polymer phonuclear (PMN) leukocytes and macrophages produce broad category of molecules including oxygen free radicals, non-radical species and reactive nitrogen species. Physiological role of ROS increase the intracellular cAMP which then activate protein kinase in male reproductive system. This indicates that spermatozoa need small amounts of ROS to acquire the ability of nuclear maturation regulation and condensation to fertilize the oocyte. There is a long list of intrinsic and extrinsic factors which can induce oxidative stress to interact with lipids, proteins and DNA molecules. As a result, we have lipid peroxidation, DNA fragmentation, axonemal damage, denaturation of the enzymes, over generation of superoxide in the mitochondria, lower antioxidant activity and finally abnormal spermatogenesis. If oxidative stress is considered as one of the main cause of DNA damage in the germ cells, then there should be good reason for antioxidant therapy in these conditions.
TL;DR: In this article, a Wistar male rat (n=30) was allocated into three groups, control (n =10), test groups (n/20) that subdivided into groups of 2 that received ginger rhizome powder (50 and 100mg/kg/day) for 20 consequence day.
Abstract: Background: Ginger rhizome (Zingiber officinale R., family: Zingiberaceae) is used medicinally and as a culinary spice. Objective: Medicinal use of ginger dates back to ancient China and India. Ginger and its constituents are stated to have antiemetic, antithrombotic, antihepatotoxic, antiinflammatory, stimulant, cholagogue and antioxidant. It has been used since ancient time as medicinal and food origins it contain antioxidative and androgenic activities and have well effect in diseases treatment in more countries world-wide. As an antioxidant’s ginger has a useful effect on spermatogenesis and sperm parameters. Materials and Methods: Wistar male rat (n=30) were allocated into three groups, control (n=10) and test groups (n=20), that subdivided into groups of 2 that received ginger rhizome powder (50 and 100mg/kg/day) for 20 consequence day. Animals were kept in standard conditions. In twentieth day the testes tissue of Rats in whole groups were removed and sperm was collected from epididymis and prepared for analysis. Results: Serum total testosterones significantly increased in experimental group that has received 100 mg/kg/day Ginger (p<0.05) in comparison to control group. Besides, the percentage of sperm viability and motility in both test groups significantly increased (p<0.05) in comparison to control group, Whereas, LH, FSH hormones, sperm concentration, morphology and testes weights in both experimental and control group were similar. Conclusion: Results revealed that administration of 100 mg/kg/day of ginger significantly increased sperm percentage, viability, motility and serum total testosterones. This suggested that ginger may be promising in enhancing sperm healthy parameters.
TL;DR: It is revealed that Iranian infertile women seeking treatment face several psychological-emotional problems with devastating effects on the mental health and well-being of the infertiles individuals and couples, while the infertility is often treated as a biomedical issue in Iranian context with less attention on themental-em emotional, social and cultural aspects.
Abstract: Background: Infertility is a major life event that brings about social and psychological problems. The type and rate these problems in the context of socio-cultural of different geographical areas and sex of people is different. Objective: The aim of this qualitative study was to explain the psychological consequences of infertility in Iranian infertile women seeking treatment. Materials and Methods: This qualitative study was done using qualitative content analysis on 25 women affected by primary and secondary infertility with no surviving children in 2012. They were purposefully selected with maximum sample variation from a large Fertility Health Research Center in Tehran, Iran. Data were collected using 32 semi-structured interviews and analyzed by the conventional content analysis method. Results: The findings of this study include four main themes: 1. Cognitive reactions of infertility (mental engagement; psychological turmoil). 2. Cognitive reactions to therapy process (psychological turmoil; being difficult to control in some situations; reduced self-esteem; feelings of failure). 3. Emotional-affective reactions of infertility (fear, anxiety and worry; loneliness and guilt; grief and depression; regret). 4. Emotional-affective reactions to therapy process (fear, anxiety and worry; fatigue and helplessness; grief and depression; hopelessness). Conclusion: This study revealed that Iranian infertile women seeking treatment face several psychological-emotional problems with devastating effects on the mental health and well-being of the infertile individuals and couples, while the infertility is often treated as a biomedical issue in Iranian context with less attention on the mental-emotional, social and cultural aspects
TL;DR: It was showed that antioxidant supplements, especially a combination of antioxidants such as vitamin C, vitamin E, and CoQ10 intake can effectively improve semen parameters in infertile men.
Abstract: Many studies have focused on male infertility. There is limited evidence about the influence of nutrition on quality of semen. Approximately, 30-80% of infertility cases are caused by oxidative stress and decreased level of seminal total antioxidant capacity. This study was aimed to review the effects of oral antioxidant supplements on improving major semen parameters such as sperm concentration, motility, morphology, DNA damage, and fertility rate. Data were extracted from PubMed and Google scholar database by using the terms "antioxidant", "multivitamin", "carnitine", "CoQ10", "vitamin C", "vitamin E", "zinc", "folic acid", "N-acetyl cysteine" and "selenium" combined with "male infertility", "semen", and "sperm" to generate a set of relevant citations. Supplements such as CoQ10 and alpha-tocopherol significantly improve sperm count. Also, carnitine has positive effects on sperm motility and morphology. Simultaneous administration of vitamin E and vitamin C reduces the sperm DNA damage. However, in some studies, one or more factors have not changed substantially. In most of the studies, antioxidant supplementation improved the number, motility, morphology and sometimes DNA integrity of sperm. The present study showed that antioxidant supplements, especially a combination of antioxidants such as vitamin C, vitamin E, and CoQ10 intake can effectively improve semen parameters in infertile men.
TL;DR: The results revealed that the main socio-cultural challenges to sexual health education for adolescents in Iran are affected by taboos surrounding sexuality, and it seems that cultural resistances are more important than religious prohibitions, and affect more the nature and content ofSexual health education.
Abstract: Background: Despite clear reasons for necessity of sexual health education for adolescents, it is a contested issue and has faced challenges in most cultures. Providing sexual education for non-married adolescents is culturally unacceptable in most Muslim societies. Objective: This qualitative study addressed socio-cultural challenges to sexual health education for female adolescents in Iran. Materials and Methods: Qualitative data from female adolescents (14-18 yr), mothers, teachers, authorities in health and education organizations, health care providers and clergies were collected in two large cities of Iran including Mashhad and Ahvaz through focus group discussions and individual in-depth interviews. Data were analyzed using conventional qualitative content analysis with MAXqda software. Results: Our results revealed that the main socio-cultural challenges to sexual health education for adolescents in Iran are affected by taboos surrounding sexuality. The emergent categories were: denial of premarital sex, social concern about negative impacts of sexual education, perceived stigma and embarrassment, reluctance to discuss sexual issues in public, sexual discussion as a socio-cultural taboo, lack of advocacy and legal support, intergenerational gap, religious uncertainties, and imitating non-Islamic patterns of education. Conclusion: It seems that cultural resistances are more important than religious prohibitions, and affect more the nature and content of sexual health education. However, despite existence of salient socio-cultural doubtful issues about sexual health education for adolescents, the emerging challenges are manageable to some extent. It is hoped that the acceptability of sexual health education for adolescents could be promoted through overcoming the cultural taboos and barriers as major obstacles.
