More than two thirds of British fertility clinics have been unable to recruit donors or have had “great difficulty” in buying supplies, since the Government lifted donors’ lifelong anonymity last year, research shows.

BBC News found that 50 of the 74 clinics and sperm banks that responded to its survey are not recruiting new donors.

There are 84 licensed centres for sperm donation in Britain. Those that can find men to donate have only 169 approved donors on their books and 90 per cent of these serve just ten clinics. There is only one registered donor in Scotland, and none in Northern Ireland.

This compares with a peak of 459 in the 1990s, when men could donate sperm knowing that any offspring would not have the right to trace them.

This provision was removed in April last year, despite warnings from fertility doctors that it would lead to a collapse in supply. The Government argued that children conceived from donated sperm or eggs had a right to know the identity of their biological parents.

Allan Pacey, head of andrology at Sheffield University and Secretary of the British Fertility Society, said: “If there aren’t enough men who are willing to donate and be identified to the donor-conceived offspring later in life, and if we don’t have the ability to import sperm from other countries because the regulations are too tough, then we are not going to be able to treat patients that require donor sperm treatments.

“Sadly some will go without. I think we are certainly in a crisis at the moment. Most of the clinics are finding it very difficult to get enough sperm to treat their patients.”

He said that many patients who needed donated sperm to conceive were considering travelling abroad.

“It leaves patients in a desperate situation. If they are unable to get treatment in their local clinic, then they are looking to other sources. Some are getting flights to other European countries. Others may turn to internet sites that provide sperm for home insemination. These are signs of desperation and I thoroughly understand them.”

Zoe and Colin Veal, whose only possibility of conceiving is by using donated sperm or an IVF technique called ICSI (intra-cytoplasmic sperm injection), were told by their Bristol clinic that there was no sperm available.

Mrs Veal said: “I think it was a huge shock as for the first time we realised that we weren’t going to be able to access treatment. You then have to start thinking about where you go from here and then you have to start thinking about risks that you might have to take, such as buying fresh sperm over the internet or whether you just move on and become a childless couple permanently. Without sperm you can’t have a baby, and so that is the end of the line.”

Mark Hamilton, chairman of the British Fertility Society, said: “The British Fertility Society is well aware of the difficulties many patients throughout the country are experiencing in accessing gamete donation services, in particular donor insemination treatment.

“Provision of such services requires significant resources to attract, recruit, screen, and counsel prospective donors. The survey reinforces our own findings that many clinics are now finding it impossible to provide these services.

“One solution may be the development of a nationally co-ordinated donor recruitment service, managed through adequately resourced recruitment centres, to meet the urgent needs of our patients.”
