You should be surprised when you first hear the term "male tube baby." How is it even possible for a man to become pregnant? In fact, it can't happen. We just wanted to use this concept to catch your attention.

More and more infertile couples turn to assisted reproductive technology (ART, also known as tube baby). But you don't know the fact that 50 percent of infertility problems are related to the husband. Varicocele, azoospermia and Idiopathic infertility are the most common conditions leading to male infertility.

In fact more than 50 percent of men with infertility can be treated by microsurgery.

Microsurgery is a microscopic surgery that can amplify x10-25, so the operation can be more accurate and effective than traditional operations.

Varicocele is the most common cause affecting 40 percent of men with primary infertility and 75 percent with secondary infertility. Some studies have shown the overall pregnancy rate stood at 43 percent to 69 percent with microsurgical varicocele repair.
