One year after a gay marriage law took effect in Mexico City, 700 gay and lesbian couples have married in the nation's capital.

The figures were released Friday by the city government.

Three-hundred-sixty-seven of the couples were male and three-hundred-thirty-three were female.

Most of the couples (456) were between 30 and 40 years of age, but 9 were in the age group of 71-90.

Lawmakers approved the law that gives gay couples all the rights and responsibilities of marriage, including the right to adopt children, in December, 2009. Previously, the city government recognized gay couples with civil unions, but gay adoption was banned. The law went into effect on March 4, 2010.

The conservative federal government challenged the law, but the nation's Supreme Court declared the law constitutional and ruled that all Mexican states must recognize the gay marriages of the nation's capital.

Following in the footsteps of Mexico City was Argentina, the first Latin American country to legalize the institution, and its first gay couple married on Friday, July 30, 2010 in provincial Santiago del Estero.

The Roman Catholic Church has harshly criticized the movement to legalize gay marriage in the region.
