THURSDAY, July 24 (HealthDay News) -- A simple, minimally invasive procedure can treat a common cause of male infertility and improve a couple's chances of having a baby, a new study finds.
The condition, called varicocele, is a network of tangled blood vessels in the scrotum which prevents the normal circulation of blood through the veins in the testicles. A minimally invasive radiological procedure called embolization can, in most cases, correct the problem.

"Using the embolization of varicoceles, we were able to improve factors related to infertility, especially sperm count and sperm motility," said lead researcher Dr. Sebastian Flacke, an associate professor of radiology at Tufts University School of Medicine in Boston.
In embolization, a small catheter is inserted into the groin and, using X-ray guidance, is placed in the varicocele. Once the catheter is placed, a tiny platinum coil and a few milliliters of an agent to ensure the closure of the gonadic vein are also inserted.
The minimally invasive procedure has a short recovery time; most patients go home the next day.
Varicoceles are very common, Flacke noted. In fact, about 20 percent of all men have them. Not all of these cause infertility or need to be treated, he said. The problem is usually treated if it causes pain, shrinkage or fertility problems.
"If you're dealing with infertility and have varicoceles -- this should be treated," Flacke said. By improving sperm count, the treatment could also be valuable in situations where the woman is having problems conceiving, he added.
"Most of the time, infertility is on both the male and female side," Flacke said. "Most of the time females get treated first if there is an issue, and men are neglected. I think you could boost the performance of the sperm if a varicocele is present and treated."
