According to "Medical News Today" on average the male reproductive system produces millions of semen every day.
Semen quality and count tend to decline as you advance in age, however. This is because older males may possess more mutations in their smen and because they may generate fewer semen.
Other conditions, including health and lifestyle, may also implicate both semen production and health.
For instance, research conducted in 2013 on mice found that exposing yourself to small particles of titanium dioxide decreases semen counts in the first generation of mice born to mothers that the researchers exposed to the particles.
Furthermore, mice whose fathers were exposed by scientists to small particles of carbon black exhibited lower semen production for two generations.
About 1% of all males and 10–15% of those with infertility do not have any semen in their had-orns. Specialists refer to this ailment as azoospermia.
In some cases, a male generates normal, healthy semen that does not travel to the had-orns as a result of blockage or other physical crisis.
In other cases, a male manufactures little or no semen. This is a result of ab issue with the bollock or endocrine system.
