The male infertility crisis is an increase in male infertility since the mid-1970s. [91] The issue attracted media attention after a 2017 meta-analysis found that sperm counts in Western countries had declined by 52.4 percent between 1973 and 2011.

Countries by fertility rate as of 2020. Total fertility rate (TFR) - the total number of children a woman would bear during her lifetime if she were to experience the prevailing age-specific fertility rates of women. TFR equals the sum for all age groups of 5 times each ASFR rate. [7] Gross Reproduction Rate (GRR) - the number of girl babies a ...
Natural fertility populations deliver an easier platform to study the reproductive behavior which may affect the levels of fertility such as pregnancy loss, time for conception, and length of breastfeeding. [24] In Pennsylvania and Ohio states in the United States, the Amish settlements have been studied to understand the age of marriage, the ...
Therefore, while reduced fertility rates are positive for society and the environment, the short term focus should be on mitigating the human impact on the environment through technological and social innovations, along with reducing overconsumption, with population planning being a long-term goal.
A 2017 review and meta-analysis found sperm counts among Western men (i.e. men in Australia, Europe, New Zealand, and North America) declined 50–60% between 1973 and 2011, with an average decline of 1.4% per year. The meta-analysis found no indication the decline is leveling off.
