Sperm Count Decline

A 2017 systematic review and meta-regression analysis, conducted by an international group of researchers, reported a significant decline in sperm count among Western countries from 1973 to 2011.

Studies involving men with infertility issues or exposure to environmental factors known to affect sperm count were excluded. Sperm motility and morphology were not part of the analysis because these factors were rarely included in older studies.

The Midlife Women's Health Summit is three days on what the research actually says about menopause care when you add a longevity lens. What works, what doesn't, what's being oversold, and what to tell the patient sitting in front of you. Co-chaired by Lisa Larkin, MD, FACP, MSCP, IF, Jen Gunter, MD, FRCS(C), FACOG, DABPM, ABPMR, and Lauren Streicher, MD, FACOG, MSCP; three of the clearest voices in women's health on separating data from marketing.
