The male infertility crisis is an increase in male infertility since the mid-1970s. [1] 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.
There has been a lot of talk in the past few years about global declines in sperm counts. Recent research found that sperm counts dropped by 1.2% per year on average from 1973 to 2018, with ...
Across the globe, male sperm count is on the decline—a decades-long drop that has been alternately blamed on pesticides, heavy metals, obesity, and potentially microplastics.More worrying, the ...
Sperm are notoriously difficult to count and the technology to do so has changed over the years. There are many confounding factors that can affect male fertility, including age, obesity and ...
Low sperm counts are often associated with decreased sperm motility and increased abnormal morphology, thus the terms "oligoasthenoteratozoospermia" or "oligospermia" can be used as a catch-all. Special obtaining
In men who have the necessary reproductive organs to procreate, infertility can be caused by low sperm count due to endocrine problems, drugs, radiation, or infection. There may be testicular malformations, hormone imbalance, or blockage of the man's duct system.
Men aren’t producing as many sperm as they were decades ago. It’s a trend observed around the globe. The pace of decline is accelerating.
Asthenozoospermia—sperm motility below lower reference limit Azoospermia—absence of sperm in the ejaculate Hyperspermia—semen volume above upper reference limit Hypospermia—semen volume below lower reference limit Oligospermia—total sperm count below lower reference limit Necrospermia—absence of living sperm in the ejaculate
