In terms of male fertility, ozone is reported to cause a significant decrease in the concentration and count of sperm in semen after exposure. [9] Similarly, sperm vitality, the proportion of live spermatozoa in a sample, was demonstrated to be diminished as a result of exposure to air pollution. [ 10 ]
Reproductive toxicants may adversely affect sexual function, ovarian failure, fertility as well as causing developmental toxicity in the offspring. [2] [3] Lowered effective fertility related to reproductive toxicity relates to both male and female effects alike and is reflected in decreased sperm counts, semen quality and ovarian failure.
Other effects directly influencing the sex of an individual include a decrease in number and quality of sperm and increased deficiency in a male's reproductive system. [ 13 ] Specifically looking at the effects of EDCs on sperm, these chemicals cause a premature release of a chemical that the sperm cells use to penetrate the egg's outer layer ...
A prolonged decline in male fertility in the form of sperm concentrations appears to be connected to the use of pesticides, according to a study published Nov. 15.
Health effects of pesticides may be acute or delayed in those who are exposed. [1] Acute effects can include pesticide poisoning, which may be a medical emergency. [2] Strong evidence exists for other, long-term negative health outcomes from pesticide exposure including birth defects, fetal death, [3] neurodevelopmental disorder, [4] cancer, and neurologic illness including Parkinson's disease ...
There is increasing evidence that the harmful products of tobacco smoking may damage the testicles [34] and kill sperm, [35] [36] but their effect on male fertility is not clear. [37] Some governments require manufacturers to put warnings on packets. Smoking tobacco increases intake of cadmium, because the tobacco plant absorbs the metal.
By Mary Gillis (Reuters Health) - Women exposed to high levels of air pollution may have less success getting pregnant with fertility treatments or staying pregnant, compared to women breathing ...
Social commentators have said that the wide-ranging consequences of male infertility necessitate the use of crisis, [13] since widespread involuntary childlessness can be viewed as a crisis. [14] Research analysis has found that amongst a sample of British newspapers in the 1990s, there was a recognizable discourse about a male fertility crisis ...
