The scrotum adjusts the temperature of the testicles, but many chastity devices loop around the scrotum. Won't this affect testicular temperature? ...and therefore be damaging to the sperm count?
The function of the scrotum appears to be to keep the temperature of the testes slightly lower than that of the rest of the body. For human beings, the temperature should be one or two degrees Celsius below body temperature (around 37 degrees Celsius or 99 degrees Fahrenheit); higher temperatures may be damaging to sperm count. The temperature is controlled by the scrotum moving the testicles closer to the abdomen when the ambient temperature is cold, and further away when it is hot. Moving the testes away from the abdomen and increasing the exposed surface area allow a faster dispersion of excess heat. This is done by means of contraction and relaxation of the cremaster muscle in the abdomen and the dartos fascia (muscular tissue under the skin) in the scrotum.

Yes

Possibly.... But, actually most studies say that heat is more damaging to sperm counts. So, by keeping everything further away from the body may help increase sperm counts.
If you are worried about it, and you are trying to have a kid. Try a different device. Or, go on the honor system for awhile. Or, I have even read about people wearing socks around their junk to help keep it warm.

This is just my experience, yours can.... and probably will.... vary!

I'm not sure where you live, but out here in New England we have these things called "clothes." They are shaped fabric swatches that you can wrap around various body parts to keep them warm.

Yep, those clothes thingies do indeed keep us warm But therein is the problem - overheating can result in low sperm count. A chastity device may limit the scrotum's ability to lower the family jewels to a cooler place and perhaps that can be a problem, I don't know. It's something I'd want to know when wearing a device for longer periods and still wanting to keep family options open. Of course not wearing clothes might solve the problem of overheating (Is this why people are into being naked around the house?! ) Or alternatively, a move to Alaska could keep things fresh.
Device dependant, but most devices actually hold the scrotum and testes further from the body, the weight of my JB pulls down and away from my body, so the overheating is less likely, the problem is more when its really cold the body wants to pull the scrotum in and the cuff ring on most devices will ultimately limit this. In terms of overheating, I think the references Tom et al made in jest about clothes is actually a serious point. If you sit in a car or at a desk for any length of time, fully clothed... the heat in your scrotum is not going to be affected by a device, even a non device wearers temperature down there would be warmer.
Sperm count/production is adversely affected by temparature, this is true. But this was an evolutionary thing long before tight briefs, jeans and various other trouser types came along. In summary I think it is not likely to be a problem. Any device should not be so restrictive to cause any decrease in blood flow, this would cause far more serious problems than low sperm count!
We were practicing MC/OD when we tried for a baby. CQ was pregnant in 5 months of trying.

In New England, it gets pretty chilly in the winter, and most of the discomfort I have from my devices is precisely *because* my testicles are trying to retract into my body.
And those mornings getting into a car when it's 14º F? That's a serious test of willpower, right there.

I just did the maths on that (well, my iphone did..) That's -10ºc Wow... Let's hope the recent bad weather you have had stays away...
I live in the upper Midwest USA. Don't come here in the middle of winter.
It is common to have a one or two week stretch where the day temp will get up to 14F (-10 C) and at night it will get to -5F (-21 C). Then we'll have a cold snap for four or five days.
Last year we had six days when the high temp was 0F (-18 C) and at night it would get down
to -15F (-25 C). We had one night it went to -25F (-32 C).
Last year from the second week of December until the first week of March we had at least 6" of snow cover.
I used to live in upstate New York and the weather was similar.
Current device - MM Custom
Previous devices - CB2000, 3000, 6000, 6000s, Curve
Don't knock your cage... it might just shatter! As your balls cling to you for warmth, did you get any problems with the cuff ring on your device as your balls tried to move back?
(Whilst this is getting off topic from the orginal OP... I gotta ask, how you function daily in those temperatures. Diesel will hit a gel point around -10c (depending on the mix..) How do you keep trucks etc running??)
