What Are the Long-term Risks of Pubic Liposuction for Males?

I think a plastic surgeon is very familiar with  the anatomy of the male pubic area and has the experience and expertise in liposuction to make them the better choice. A urologist may have no training whatsoever in liposuction as it is  outside of their training and clinical practice.
When liposuction is done for males or females around the pubic area the opposing hand and fingers are placed over the base of the penis or clitoral hood as a backstop to make sure that the areas suctioned are well away from these areas. The suction is done carefully and precisely to contour just what is needed and to avoid trauma to the genital structures. 
Pubic liposuction is commonly done for males and females in a plastic surgeon's practice. I would advise you to consult with a plastic surgeon who is board-certified by the American Board of Plastic Surgery.

Liposuction is an excellent
method for treating localized fat collections. The procedure significantly improves contour and is associated with high
satisfaction rates. In addition, the
procedure is considered safe and has low complication rates.The
majority of liposuction complications are related to inadequate aesthetic
results. These include contour
irregularities, dimpling of the skin, skin sag and asymmetry. In addition, infection, bleeding, hematoma
formation, scarring and, rarely, injuries to the deeper structures can occur
with this type of procedure. When the
pubic area is liposuctioned, sexual function is not affected.The
majority of these complications resolve with time or, in some cases, can be
treated with additional surgery.Ultimately, the vast majority of patients are satisfied with their
results.

Liposuctioning of the pubic mons is a very easy, straight-forward procedure under local anesthesia for around $2500 with no down time.  There is a lot of bruising and swelling in the genitals but no permanent sexual dysfunctions.
