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. [2][3] The decline is particularly prevalent in Western countries such as New Zealand, Australia ...
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 ...
Semen quality is a measure of male fertility, a measure of the ability of sperm in semen to accomplish fertilization. Semen quality involves both sperm quantity and quality. Semen quality is a major factor for fertility. An amount of human semen of unknown quality. Cryptorchidism, hypospadias, testicular cancer and poor semen quality make up ...
A 2022 meta-analysis reported that this decline extends to non-Western countries, namely those in Asia, Africa, Central America, and South America. [95] This meta-analysis also suggests that the decline in sperm counts may be accelerating. [95] This decline in male fertility is the subject of research and debate.
The pace of decline is accelerating. 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.
Hypospermia is a condition in which a man has an unusually low ejaculate (or semen) volume, less than 1.5 mL. It is the opposite of hyperspermia, which is a semen volume of more than 5.5 mL. [1] It should not be confused with oligospermia, which means low sperm count. Normal ejaculate when a man is not drained from prior sex and is suitably ...
A team of scientists is sounding the alarm about declining sperm counts among men in the Western world.
