Don?t get your shorts in a twist over it just yetPosted by jesuslewis on August 10th, 2017 Stories this week about a study reporting sperm counts among Western men have fallen by more than half in less than 40 years had researchers warning of a fertility “crisis” and others offering tips on how men could counteract the “shocking” and “all-time low” sperm slump by, among other things, eating tomatoes and pomegranates. However, a Canadian expert in human sperm pathophysiology says semen analysis tests are among the most poorly performed medical laboratory tests on the planet, with a margin of error as high as 50 per cent, and that while Monty Python sang that every sperm is sacred, what matters most isn’t the number of swimmers but morphology and motility — two heads instead of one? Too timid or sluggish? Yes, all sorts of “nasty” things in the environment are undoubtedly affecting male fertility, says Vancouver’s David Mortimer, president and co-owner of Oozoa Biomedical, an international consulting company in reproductive biology. But it’s not necessarily time to get our shorts in a twist. The new study, appearing this week in the journal Human Reproduction Update, is billed as the first systematic review and meta-analysis of trends in sperm counts. Researchers from the Hebrew University-Hadassah Braun School of Public Health and Community Medicine and the Icahn School of Medicine at Mount Sinai, New York analyzed 185 studies involving nearly 43,000 men from six continents and 50 countries who provided semen samples from 1973 to 2011.
