But the authors of the latest study say they have addressed such concerns, analysing only studies that used the same sperm count method, were of a reasonable size and involved men not known to have infertility problems or disease, among other measures.
But he agreed there is cause for concern around male reproductive function, pointing out that rates of testicular cancer are on the rise, and stressed that men who are concerned about their sperm count and who wish to have children should not delay. Numerous possibilities have been mooted, with research suggesting links to body weight, a lack of physical activity , smoking , and exposure of pregnant women to chemicals found in myriad household products, known as endocrine disruptors. Levine agreed that research into potential causes was needed. While infertility treatments such as IVF can offer solutions to potential ramifications of the decline on one level, little has been done to address the root of the issue, said Levine, pointing out low sperm counts might also be an indicator of poorer health among men more generally. The team split the data based on whether the men were from western countries — including Australia and New Zealand as well as countries in North America and Europe — or from elsewhere.
