You may be interested in this article written by Professor Sheena Lewis who is Professor of Reproductive Medicine at Queen’s University Belfast about the increase in fertility problems and what she believes could be to blame.
Professor Lewis has carried out research into unexplained infertility which she says is often caused by undiagnosed male factor problems, in particular sperm DNA damage.
Professor Lewis makes the argument in her article that there is simply not enough research being carried out into the field of fertility, particularly considering how widespread the problem is – and she clearly feels that the current treatment funding situation is simply not good enough.

We’re always told that infertility is a growing problem and there have been some dire warnings about the way it will affect future generations – but a new global survey suggests that the picture may not be quite so bleak. A study published in PLoS Medicine which analysed regional, national and worldwide trends in infertility found that there was very little difference in the rates of infertility between 1990 and 2010 – and that there had been declines in the numbers in some parts of Africa and South Asia.
The report’s authors do add a note of caution to their findings as they looked at couples who didn’t have a child after five years as a benchmark, and they say that the levels would probably be higher had they looked at those who had reported having a problem – in reality many couples who experience difficulty conceiving do manage to have a child before five years have elapsed.
