Most people hear about prolactin only during pregnancy, but high prolactin levels can affect both women and men , even if they are not planning a baby. In this article, we will explain everything about prolactin in very simple words — what it is, why it increases, how to check it, problems caused by high prolactin, natural ways to reduce it at home , and safe medical treatments . What Is Prolactin? Prolactin is a hormone that mainly helps in milk production after childbirth . But its role does not stop there. It also affects: Menstrual cycle Ovulation Fertility Sexual health Mood and stress balance When prolactin stays within normal range, the body works smoothly. When it becomes too high, many problems can start silently. Where Is Prolactin Produced? Prolactin is produced by a small but powerful gland cal...
A new study in the journal Cell reveals something surprising: ancient viruses may have helped shape our bodies and brains. These viruses, which infected vertebrates millions of years ago, played a crucial role in the evolution of our nervous systems and large sizes. Researchers focused on a substance called myelin, which coats nerve fibers and helps messages travel quickly in our bodies. They found that a gene sequence from these old viruses is essential for making myelin. This gene is now found in many animals, from mammals to fish. Dr. Tanay Ghosh, who led the study, searched through DNA databases to find clues about how myelin evolved. He discovered a specific sequence called "RetroMyelin" that comes from these ancient viruses. When they experimented with cells, they found that knocking out this sequence stopped them from making myelin. What's really interesting is that this RetroMyelin sequence isn't just in mammals like us – it's in all sorts of animals with...
