I want to know whether there is any advanced treatment for azoospermia?

Yes! Well, actually, it depends on what you mean by "treatment". If you mean "cure", then it depends on the cause of azoospermia. Some men with azoospermia due to a large varicocele, for example, may have better sperm after surgical treatment. Men with congenital absence of the vas deferens, as another example, can typically have sperm surgically extracted and injected into eggs during ivf.
