Chlamydia makes men infertile too, a new study finds. Spanish scientists say that infected sperm has three times more damage, or DNA fragmentation, as healthy sperm. Its density, shape and swimming ability also decline. But an antibiotics treatment repaired the damage by 36% over 4 months, and almost 90% of couples were able to conceive after the study.
Chlamydia is rampant and rates are rising, with up to 1 in 10 people aged 18-25 carrying the disease in the UK. Yet few men are ever diagnosed because symptoms can be minor, the BBC reports. A UK doctor says the remedy is more screenings: "There should be a page on Facebook you can log onto and sort screening out.”
