Sexually transmitted diseases (STDs) are a common group of infections that are often overlooked but can have serious implications for reproductive health if not detected and treated promptly. Common examples include syphilis, gonorrhea, chlamydia, human papillomavirus (HPV), genital warts, genital herpes, and HIV. Most of these infections may not present clear symptoms in the early stages, yet they harbor significant risks that can adversely affect long-term health.
