Weight lifting and varicocele

Hey T-dudes,
i recently read something about a guy feeling pressure in his testicles after wight lifting.
He was told by a doctor that wieght lifting can cause the intestines to “pop out”,putting extra pressure on the testicles, thus increasing the chance of varicocele.I was just wondering what your opinions were on this.I have already had varicocele in one of my balls treated,and let me tell you it wasn’t fun.
