Q: लैंगिक संचारित रोग (STD) क्या हैं? जीवाणु और विषाणु जनित किन्हीं चार STD के नाम लिखिए तथा इनसे बचने और जनसंख्या वृद्धि को नियंत्रित کرنے के लिए उपयोग की जाने वाली विभिन्न गर्भनिरोधक विधियों को समझाइए।

Introduction to Sexually Transmitted Diseases (STDs)\nInfections that are spread from person to person through sexual contact are called Sexually Transmitted Diseases or STDs. They can be caused by bacteria, viruses, or parasites. Unsafe sexual practices are the primary mode of transmission. Examples of STDs Bacterial STDs: Gonorrhea Syphilis Viral STDs: Acquired Immunodeficiency Syndrome (AIDS) caused by HIV Genital Warts caused by Human Papillomavirus (HPV) Methods of Contraception and Prevention\nContraception refers to the deliberate prevention of pregnancy during sexual intercourse. These methods also play a crucial role in preventing the transmission of STDs (especially barrier methods). Barrier Methods: Use of condoms (for males and females) which prevent the physical contact of body fluids and sperm. They are the only contraceptive methods that also protect against STDs. Chemical Methods: Use of oral pills (hormonal preparations) that alter the hormonal balance of the body so that eggs are not released and fertilization cannot occur. Use of spermicides that kill sperm. IUDs (Intrauterine Devices): Devices like Copper-T placed in the uterus by doctors to prevent implantation, though they do not protect against STDs. Surgical Methods: Vasectomy: Blocking the vas deferens in males to prevent sperm transfer. Tubectomy: Blocking the fallopian tubes in females to prevent the egg from meeting the sperm. Conclusion\nAwareness, safe sex practices, and the correct use of barrier contraceptives are essential for controlling population growth and maintaining reproductive health.
