no i am sorry because one of your testicles needs to be active in order to produce the right kind of sperm
yes you can (I did)
Yes.
A 30 year old will have no problem having children if he has only one testicle, as long as that single testicle is in good health.
Absolutely - the man would simply be unable to sire children.
If both are healthy, both will produce sperm.
no. the testes produces sperms
No, both testicles do the same job, they aren't differentiated in any way.
Nope, each testicle both produces and stores the sperm.
In a healthy male with intact genitalia and testes, there should be no difference in the production between left & right. For practical reasons it would be nearly impossible to measure output or quality between left and right.
Testify and testicle both come from the Latin "testis" meaning "witness." Testicles are witness to a man's virility.
Yes, a man with one testicle can still have children. As long as the remaining testicle is healthy and functioning properly, it can produce enough sperm for conception. Many men with one testicle have fathered children successfully. However, individual fertility can vary, so consulting a healthcare provider for a fertility assessment may be beneficial.
Hospital, or destroy both and help the gene pool get better
