Britain is in the grip of an epidemic of sexually transmitted infections. The number of cases of gonorrhoea has doubled in the last 5 years the number of confirmed syphilis cases has risen tenfold! But Chlamydia remains the most worrying infection.

Chlamydia
Three times as many people sought treatment for Chlamydia last year than in 1996. As many as 1 in 10 men and women under 25 now carry the infection, which is a major cause of female infertility.

Most will have no symptoms and remain unaware they, or their partners, have a problem.

Chlamydia can be detected using a urine test and most cases can be cured with just a one-off dose of antibiotic. Is it time we had a routine national screening programme?

HPV
Over half of all sexually active women are infected with the human papilloma virus the virus responsible for genital warts and the principal cause of cancer of the cervix. Most women wont develop warts but that wont stop them getting cancer.

Could a new vaccine against HPV be the first vaccine to protect against cancer? And if we can conquer HPV will we still need routine smear tests and the national cervical cancer screening programme?

Viagra
Levitra and Cialis are two new versions of Viagra but how do they stack up against the original? Supplies of all tadalafil 20mg
for impotence remain severely restricted on the NHS and most men have to pay for them.

The generic tadalafil softtabs
rush following the launch of Viagra never arrived. Is it time now to relax the rules? And should drug companies be lowering the prices up to 6 a dose is extortionate for any medicine, let alone one that sells in the volume that Viagra does?

Cialis wonder buy genuine tadalafil
Pill
The latest version of the morning-after pill, Levonelle, is more effective and better tolerated than its predecessor and is available without buy cheap tadalafil
. But what impact has this had on unplanned generic erectile dysfunction drug in teenagers (the UK has the highest rate in Europe)? And has it encouraged the growth of sexually transmitted diseases?
