Reactive oxygen species, also known as oxygen and oxygen-derived oxidants, cause cellular damage at a higher rate under the term "oxidative stress" (ROS). Oxidative stress is typically present as a background factor in all live aerobic cells. This oxidative process can be accelerated and lead to cell damage by several stress-related situations, including chronic disease states, aging, toxin exposure, physical injury, and exposure to a variety of foods. One of the main contributing factors to infertility is thought to be the malefactor. A new and significant reason, oxidative stress, has been...

Androgens are important steroid hormones that control how the male phenotype is expressed, including the establishment and maintenance of spermatogenesis as well as the external development of secondary sex traits. The development of male reproductive organs such as the epididymis, vas deferens, seminal vesicle, prostate, and penis is greatly influenced by androgens. Additionally, males require androgens during puberty, masculine sexuality, and reproduction. Spermatogenesis requires a lot of intratesticular testosterone, which is released by the Leydig cells. The majority of the...

The dengue virus is currently one of the most widespread arboviruses infecting human populations, with serious negative effects on South America and South-East Asia economies and societies. Inadequate funding, wrong policies, a lack of political will, expanding mosquito vectors, and increasing urbanization and globalization are some of the factors contributing to the failure of initiatives to address this serious public health issue. Recent data estimates that there were 96 million apparent dengue illnesses globally in 2010. This figure, which is far higher than the WHO projection, shows that...

Le virus de la dengue est actuellement l'un des arbovirus les plus répandus parmi les populations humaines, avec des effets négatifs graves sur les économies et les sociétés d'Amérique du Sud et d'Asie du Sud-Est. Un financement inadéquat, des politiques erronées, un manque de volonté politique, l'expansion des moustiques vecteurs et l'augmentation de l'urbanisation et de la mondialisation sont quelques-uns des facteurs qui contribuent à l'échec des initiatives visant à résoudre ce grave problème de santé publique.

Infertility is a disease of the reproductive system. It makes a person unable to have children. It can affect a man, a woman, or both. Male infertility means that a man has a problem with his reproductive system. It means you cannot start a pregnancy with your female partner. Since they haven't been able to produce a child despite engaging in frequent, unprotected sexual activity for a year or longer, nearly one in seven couples are infertile. Up to half of these partners are affected to some extent by male infertility. Low sperm production, abnormal sperm function, or obstructions that...
