The overall Count will be a bit lower, but if that testicle is healthy, the man will still be fertile.
If both are healthy, both will produce sperm.
yes
I am told that well over 9000 testicles are required to make testicle soup.
In most cases the doctors would put a 'falsie' in the scrotum. As long as the other testicle is healthy, it would not prevent reproduction.
In a word - No. There is no surgical means to create or substitute for the missing one.
Usually hard impacts to the testicles will make them swell up. Continued hard strikes can make testicles rupture (often referred to as popping). When the testicle ruptures the side of the testicle will tear and the insides of the testicle a white jell like substance will come out. If the testicle is then flattened all of the internal content will come out and the testicle will have to be removed. If it is not flattened surgery can sometimes save the testicle through stitching up the tear.Boys / men will likely throw up or pass out when such injuries occur as the pain is so intense.
Not if only one testicle is removed. You can produce sperm just fine with only one testicle
Yes, as long as the testicle is functioning properly then you can reproduce with one testicle.
When a man has a testicle removed by a doctor, he may opt to have an implant put into the scrotum in order to make it seem like he still has both testicles. The implant does nothing other than occupy the empty space where the removed testicle once resided.
Is having just one testicle normal, no. Normal is men have two testicles, but it does happen. Sometimes due to an accident or illness, sometimes a boy is born with only one developed testicle and as long as it is healthy, your sex life and fertility will not be effected. Make sure you see a doctor to ensure you don't have an undescended testicle or a hernia. If the second testicle is trapped in your abdomen, it can be strangled and the one testicle you can see could end up slipping through the hernia too.
The left testicle does the same as the right testicle, which is to produce sperm cells. Combined both testicles actually make 1,000 sperm cells a second. Although, you must take into account a large number of those cells will be deformed / unusable. (About half)
