When Cojones come to be heated up too much, it could end up affecting semen manufacturing and it can lead to it being tougher for a man to fertilize a woman. A periodic transition in climate does affect sperm fabrication. Cold climate can increment a man's semen result and increase your odds of conceiving. Frequently, there is a rise in the number of newborns during fall stacks up against other seasons. Nonetheless, this has not been scientifically proven. For those having a tough time to conceive, this can be good news.
When it is cold outside especially during the winter period human beings tend to keep warm inside the house and one thing leads to another. It is not rocket science.
This is the first time that I have heard of an increased production of semen when it is cold. I agree that hot temperature affects the testicles but I don't really know if it has something to do with the production of semen. My take on the weather is that it can really affect the appetite to make love that may lead to pregnancy.
I never heard this thing that the production of man's sperm cells is affected by the different weather conditions. That is back up scientific study or research. Most common factors that determine or affect the normal production of sperm cells are but not limited to emotional stress, drugs, alcohol, depression and weight.
The end result of the appetite of baby-making is making a baby off course. If you are not on any contraceptive chances are that you will end up pregnant.
