Students have reported difficulty accessing services

The students' union said appointments at the Woolmanhill Genito-Urinary Medicine clinic were being turned down.

The clinic admitted that one-in-10 people on its waiting list for treatment were probably infected.

A sexual health plan, stressing information and access to services, was launched by ministers in January.

But the students' union claimed efforts to combat infections were being undermined by the lack of access to treatment.

It said students have had to fabricate symptoms or pretend they fall into a high-risk category to be seen.

Doctors at the Aberdeen Royal Hospital sexual health clinic admit that they are currently overwhelmed by demand and that the waiting list for a routine check-up is currently one month.

The Scottish Executive's Action Plan for Improving Sexual Health is aimed at tackling high rates of Sexually Transmitted Diseases (STDs) and unwanted pregnancy.

It has pledged redesigned sexual health services to ensure improved access in all areas of the country.

But students' union spokesman Paul Richards said: "If the NHS can't be providing this, then there's no point in the Scottish Executive and student associations and whoever else running campaigns raising awareness, because there's no solution."

'High risk groups'

A NHS Grampian spokesman said: "We are aware of the issues surrounding waiting times at the GUM clinic. Patients are however prioritised to ensure that high risk groups are seen as soon as possible.

"These include under 18s and patients with contact with infection or those with symptoms."

He added that NHS Grampian had been allocated �400,000 in government funding and an action plan would be drawn up with the executive "by the end of the month".

An Aberdeen University spokesman said: "The health and well-being of the university students is very important to us and is always a priority.
