: Research into the physiological changes of the breast and nipple-areola complex over time often uses terms like "involution" or "ptosis" rather than "seamed" [5].

: In mechanical engineering, "nipples" can refer to small pipe fittings. "Seamed" could refer to the manufacturing process of the metal tubing (seamed vs. seamless), though "mature" would be an unusual descriptor in this field.

If you are looking for research on or nipple reconstruction techniques , I can provide more specific papers on those topics. If this was a specific term from a text you've read, providing a bit more context would help me track down the exact reference.

It is possible this phrase refers to one of the following specialized areas, or may be a specific search term from a different context:

: In bra or lingerie manufacturing, "seamed" refers to cups made of multiple pieces of fabric stitched together (as opposed to molded, seamless cups). These seams are often designed to provide specific lift or shaping for "mature" figures where tissue density has changed [3, 4].
