With 374 million new curable STI infections among adults aged 15 to 49 in 2020, the numbers are both staggering and deeply personal. This post brings together contraception, pregnancy, and sexual health statistics across countries to show where gaps in access, education, and outcomes really sit. You will come away with a clearer picture of what is changing, what is not, and which questions matter most.

While the statistics paint a sobering picture of widespread and often unspoken human struggle—with nearly half of men and women grappling with various sexual dysfunctions—it also reveals a profound and universal opportunity for medicine to move beyond silence and shame toward honest care and connection.
How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
