5 Most Common Causes of Infertility


Varicoceles might look a little alarming, but they're common -- 40 percent of men struggling with infertility have them [source: WebMD]. Put simply, they're varicose veins in the scrotum. Put a little more scientifically, it's when the veins in the spermatic cord responsible for getting blood to the testicles are backed up. Doctors and nurses refer to the look and feel of a varicocele as "a bag of worms." Just what you want your scrotum to be described as!

Not all varicoceles need to be fixed -- just if they're painful or messing up your sperm production. The solution? Surgery or a procedure called varicocele embolization, which is becoming more popular because, unlike surgery, it doesn't require general anesthesia or cutting into the scrotum (four words that should never be typed together).
