The National Assembly has revised the law to allow medical professionals to reveal the gender of a fetus before week 32 of pregnancy.

The revisions, passed during a plenary session on Monday, come after a Constitutional Court ruling in February that Article 20, Section Two, of the Medical Service Act violated the Constitution.

That section prohibited doctors from disclosing the gender of a fetus before week 32 of pregnancy.

It was first put into effect in 1987 to prevent the abortion of female fetuses when families tended to favor boys over girls, and the “before week 32 of pregnancy” stipulation was added in 2009.

With the court ruling in February, Section Two immediately became invalid.
