Xiaflex® and Peyronie’s Disease

Dr. Hossein Sadeghi-Nejad is trained to administer the Xiaflex® treatment to men with Peyronie’s disease (PD).

Xiaflex® is the only FDA-approved medication for PD.

Dr. Hossein Sadeghi-Nejad is a urologist in the northern New Jersey / NYC area who treats men with Peyronie’s disease. Peyronie’s disease – or its acronym, PD, as it is sometimes referred to -- is a medical condition described by fibrous scar tissue in the penis. The condition leads to curved erections that are also painful and that can prevent intercourse. Dr. Sadeghi-Nejad is on the forefront of research on Peyronie’s disease and has received special training in the administration of Xiaflex® intralesional injections for the treatment of PD.

Xiaflex® treatment includes a series of injections that work to disintegrate the scar tissue associated with Peyronie’s disease that is responsible for “the curve.” There are other treatment options for PD, both surgical and nonsurgical, but Xiaflex® is considered the most effective nonsurgical treatment available.
