Introduction:

The Yuzpe regimen, named after Dr. Albert Yuzpe who developed it in the 1970s, is a method of emergency contraception. It involves the use of combined oral contraceptive pills containing estrogen and progestin to prevent pregnancy after unprotected sexual intercourse or contraceptive failure.
