  • PrEP (daily pill) is 99% effective against HIV — available at government ARTC centers in India

Why I Always Ask About STI Testing in My Clinic

I’ve made it a habit to ask every sexually active patient who visits my clinic: “When was your last STI test?” The most common answer is: “I don’t have any symptoms, so I don’t think I need one.” That’s exactly the problem. 50% of all STIs produce no symptoms at all — yet silently cause infertility, organ damage, and transmission to partners.

Getting tested isn’t a confession of recklessness. It’s an act of responsibility — for yourself and your partner. In my experience, the most responsible, thoughtful patients are the ones who come in for annual screenings even when they feel fine.

The Global STI Burden: Numbers You Should Know

WHO estimates over 1 million new STI infections occur every single day worldwide. The four most common curable STIs — Chlamydia, Gonorrhea, Syphilis, and Trichomoniasis — together cause 376 million new infections annually. In India, ICMR estimates 37.7 million STI cases per year, with Chlamydia and Gonorrhea leading.

Safe Sex Toolkit: Practical Guide

Condom use — the right way: Check the expiry date. Open carefully (not with teeth or scissors). Pinch the tip to remove air before unrolling. Use from beginning to end, not just at climax. Use water-based lubricant only — oil-based lubricants degrade latex. Store at room temperature, not wallets (heat degrades latex).

Internal condoms (female condoms): Provide similar protection, allow women to control their own protection. Can be inserted up to 8 hours before intercourse.

PrEP for HIV prevention: Daily Tenofovir/Emtricitabine (TDF/FTC) reduces HIV acquisition by 99% when taken consistently. Available free at ART centers in India for high-risk individuals. Doesn’t protect against other STIs — use with condoms.

HPV Vaccine: Who Needs It

Gardasil 9 protects against 9 HPV strains causing 90% of cervical cancers and most genital warts. Ideally given before first sexual contact (ages 9-12), but effective up to age 45. 3-dose schedule over 6 months. Cost in India: ₹2,000-3,500/dose at private clinics; some government programs offer it free for girls. Men can also benefit — HPV causes penile, anal, and throat cancers too.

Having the STI Conversation with Your Partner

Choose a calm, private moment — not right before or during intimacy. Be direct and non-accusatory: “I care about both our health. Can we get tested together before we have sex without condoms?” Frame it as teamwork, not suspicion. If a partner reacts with anger to a reasonable health request, that itself is important information about the relationship.
