Whether paired variable reduction is difference between groups

I have two variables, triglyceride before and after treatment.

So I run the paired t test to see if triglyceride reduction is significant after treatment.

Then I run the test in different genders. The significance exists in both men and women.

Is there a test in Stata, which I can run to determine if the triglyceride reduction is significantly different between men and women?

Thank you very much.
