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.
Males from India had a 30.3% decline in sperm count, 22.9% decline in sperm motility, and a 51% decrease in morphology over a span of a decade. Doctors in India disclosed that the sperm count of a fertile Indian male had decreased by a third over a span of three decades. [82]

The research is mixed on whether cycling affects male fertility, including sperm—but doctors offer some tips on protecting your swimmers, if you have concerns.
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
Hims reports that the respondents who used their phone more than 20 times per day had a 30% increased risk for lower sperm concentration and 21% increased risk for total sperm count to be below ...
