FOR IMMEDIATE RELEASE

AMERICAN MEDICAL SYSTEMS REPORTS STRONG FOURTH QUARTER REVENUE OF $114.8 MILLION

Significant Strength seen in both Base Business and Laser Therapies

MINNEAPOLIS, January 5, 2007 — American Medical Systems Holdings, Inc. (NASDAQ: AMMD) reported preliminary sales of $114.8 million for the fourth quarter of 2006, a 57 percent increase over sales of $73.1 million in the comparable quarter of 2005. Preliminary sales for the year 2006 were reported at $357.7 million, a 36 percent increase over sales of $262.6 million for the year 2005. The Company’s organic growth rate for the fourth quarter and fiscal year, adjusted for the July 2006 Laserscope acquisition, were both 18 percent.

The Company experienced strong growth across all businesses including its laser therapy business which was acquired in July 2006. Martin J. Emerson, President and Chief Executive Officer, noted, “The fourth quarter represented the first full quarter of the Laserscope operations, and the business finished strongly with $28.5 million in fourth quarter sales, representing accelerating customer demand for ourGreenLight HPS™system. Clearly, our supply chain focus has paid off as we built and sold 96 HPS consoles in the quarter.”

The Company’s base men’s health business, which grew 15 percent in the fourth quarter and 12 percent in the fiscal year, experienced its highest growth rate in several quarters, led by the rapid acceptance of the700 MS™product line introduced in late November 2006. The700 MSproduct line offers improved performance and ease of use for the 700 series, already the market leading inflatable penile prosthesis in the world. TheAdVance™launch in late November contributed to the significant male continence growth rate for the quarter.

The Company’s base women’s health business, which grew 22 percent in the fourth quarter and 28 percent in the fiscal year, continued to see significant increases in prolapse and uterine health products. Prolapse products again reported strong sequential growth for the quarter. This significant growth is the result of physician conversion related to the Company’s investment in physician training and clinical data supporting the safety and effectiveness of bothApogee™andPerigee™. In uterine health, sales ofHer Option™more than doubled in the fourth quarter compared to the prior year and increased 30 percent sequentially from the third quarter as physicians and their patients continue to recognize the ease of use and comfort that comes from this in-office procedure.

Mr. Emerson added, “There was balanced strength across all products, and we also saw expansion in our international growth rates this quarter. International sales now account for 26 percent of the Company’s total sales. As we look at the Company’s many accomplishments in 2006, and most significantly, the acquisition and assimilation of Laserscope, I am very pleased with the strong sales momentum with which we exit the year. Entering 2007, AMS has its strongest product offering ever, driven by proven technology platforms.”
