{{Women should not worry about using sperm from older donors as the success rate is the same as using a younger man’s sperm, researchers say. }} <\/p>\n

The average age of donors has risen in the UK since the right to anonymity was removed in 2005.<\/p>\n

Doctors said there was concern about the impact on the odds of a pregnancy.<\/p>\n

Experts said only older men with the best sperm could donate, so men as a whole should not see the results as an excuse to delay fatherhood.<\/p>\n

A presentation at the European Society of Human Reproduction and Embryology annual conference showed the average age of donors was 26 before the law change and 34 afterwards.<\/p>\n

“It is a huge difference,” said Dr Meenakshi Choudhary from the Newcastle Fertility Centre.<\/p>\n

“It may concern women, who are already older, who know their chances are lower, that if they go for an older sperm then their chance of a live birth will be further reduced and compromised.” <\/p>\n

She analysed data from 39,282 cycles of IVF between 1991 and 2012, concluding that older men had the same success rates as younger men.<\/p>\n

Dr Meenakshi Choudhary told media: “It doesn’t matter up to the age of 45 years, there was no decline observed in this study.<\/p>\n

“Sperm donors are a select group of the population, they are healthy fertile donors who go through a stringent recruitment criteria.<\/p>\n

“Based on this we can say that age does not matter as long as the sperm quality is good.”<\/p>\n

{{‘Men not invincible’}}<\/p>\n

Dr Allan Pacey, a lecturer in sperm at the University of Sheffield, said men should not be tempted by complacency.<\/p>\n

He told the media : “I think there is a perception out there that men are invincible from reproductive ageing – we just need to look at Charlie Chaplin who was 73 when he had his eleventh child.<\/p>\n

“We know that as men go above the age of 40 and go into their fifties, their chances of getting a woman pregnant does reduce as a consequence of age.<\/p>\n

“I don’t think you can take this data and apply it uncritically to the general population, the advice would still be you should be trying to have a child before the age of 40 or 45.”<\/p>\n
