Stretchesīrandeis says there is a stretching technique called jelqing which involves manually pulling on the penis, however, he says there is no scientific evidence that proves it to be effective. Because of both of these reasons, you should stay away from lotions that advertise penis enlargement. Yih adds that these products are not FDA-approved. While you may see penis enlargement lotions and creams on the market, Brandeis says these have not been proven to be effective in any scientific studies.
