Modulator was stating "目前還沒有實際證據能證明這種說法" but this is not a positive proof, this is a negative proof, which is not comforting.
Lets look at just ONE fact: Roughly, a healthy male produce some 200 million sperms per day, while a healthy female produce one egg per month, who do you think will more likely suffer auto-immune disease because the "way to freedom" is blocked and the sperm/egg need to be re-absorb into the body ? ? ?
Just proof to me that there are no increase probability of auto-immune disease for tieing the tube for male.
I am POSITIVE you cannot provide that positive proof. |
