A diastasis does not become a problem until the connective tissue becomes weakened. The connective tissue can be weakened from previous abdominal surgeries, taking part in sports with a cross-over movement (i.e. tennis, golf), doing crunches, and getting a "guy gut". Once the connective tissue has been weakened, men are prone to suffering from the same problems (bad back, poor posture, gastro intestinal issues) as women.
Generally speaking, the healing time for men is faster than for women because their connective tissue is stronger. This is because it has not been affected by the relaxin that impacts women's connective tissue during pregnancy. However, males who have used steroid injections will suffer from weaker connective tissue.
