No. But it is better for fertility if they are lower than the core temperature of the body.
The "Ball Sack" is called a "scrotum" and contains testicles.
Males have testicles.
Sperm are produced externally because there is a certain temperature at which they survive. for this reason, when its cold, your testicles "shrink" to warm up and keep it at the required temperature. when its warm on the other hand, your testicles "drop" to drop the temperature
because they must maintain a certain temperature. they get closer to your body to stay warm in winter and the opposite in the summer time **To properly form sperm the testicles need to remain at a very high body temperature. The scrotum(sack that holds the testicles) will flex and relax to maintain this temperature.
Males don't have ovaries, males have testicles instead. The testicles produce sperm, which through intercourse merges with an egg from the female to create a baby.
Testicles are held in the scrotum which hangs them outside the body where it is cool enough for spermatozoan production. The function of the testicles is spermatozoan production.
when the testicles are not undescended it affects the temperature which causes infertility due to no sperm production.Adult males with cryptorchidism typically have lower sperm counts and produce sperm of poorer quality than men with normal testicles
Males that have not been castrated only have testicles.
cryptorchidism which is undescended testicles in males is one example
In females it is the ovaries and in the males it is the testicles.
they are the 2 "balls" that create sperm which are located underneath the penis in males.
During puberty, a males testicles will get lower and increase in size.
