Gosnell, 72, did not take the stand and the defense called no witnesses.
Defense lawyer Jack McMahon has done his work by challenging witnesses on cross-examination. The court is now in recess until Monday when closing arguments will be heard.
Gosnell is charged with killing four babies allegedly born alive at his clinic. He is also charged in the 2009 overdose death of a 41-year-old refugee who died months after coming to the U.S.
