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.
The main cause of male infertility is low semen quality. 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.
Terms oligospermia, oligozoospermia, and low sperm count refer to semen with a low concentration of sperm [1] and is a common finding in male infertility. Often semen with a decreased sperm concentration may also show significant abnormalities in sperm morphology and motility (technically oligoasthenoteratozoospermia). There has been interest ...
While a sperm analysis can determine what's happening, other issues may be the root cause of male infertility. "The most common thing that causes infertility in men is a condition that's called ...
Aspermia is the complete lack of semen with ejaculation (not to be confused with azoospermia, the lack of sperm cells in the semen). It is associated with infertility.. One of the causes of aspermia is retrograde ejaculation, because of that the sperm is kept into the bladder and the final ejaculate is 0 mL. [1]
It decreases the sperm quality and is therefore one of the major causes of infertility or reduced fertility in men. A method to increase the chance of pregnancy is ICSI . [ 1 ] The percentage of viable spermatozoa in complete asthenozoospermia varies between 0 and 100%.
Azoospermia is the medical condition of a man whose semen contains no sperm. [1] It is associated with male infertility, but many forms are amenable to medical treatment.In humans, azoospermia affects about 1% of the male population [2] and may be seen in up to 20% of male infertility situations in Canada.
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 ...
