Sexually transmitted disease among seniors is rising amid more social, sexually active lifestyles.

New research published Thursday by the British Medical Journal shows that 80% of 50 to 90 years olds are sexually active. And with that, cases of sexually transmitted diseases have more than doubled in this age group over the past 10 years

Men often avoid condoms because of issues with erectile dysfunction and older women are more vulnerable to disease physiologically because of the changes which occur as their bodies age.

Numbers from the Centers for Disease Control and Prevention indicate that incidences of syphilis and chlamydia in adults aged 45 to 64 have nearly tripled over the past decade. Cases of Gonorrhea are up as well.
