Officials in Mexico City say 88 gay and lesbian couples married in the first 30 days since gay marriage became legal in the city, the AP reported.

The city government said 50 of the couples consisted of gay men and 38 of lesbians.

Mexico City became the first municipality in Latin America to legalize the institution on March 4. Nearly 10 million Mexicans live in the city, which is also home to the nation's largest gay community.

The law is opposed by Mexico's conservative National Action Party (PAN), which controls much of the country, including the federal government.

In an effort to derail the start of the law, Mexico's federal government appealed to the country's Supreme Court. The federal Attorney General's Office argued that the law, which allows gay couples for the first time to adopt, was unconstitutional because it “strays from the responsibility of the government to place a priority on safeguarding the interests of children.”

While the court has yet to review the federal challenge, it upheld the law in rejecting challenges brought by the governors of three PAN-controlled states. The governors had argued that the law would force their state governments to recognize the marriages of gay couples from Mexico City. The court, however, said the states did not have the legal authority to challenge the laws of another state or the nation's federal district of Mexico City.

An additional 37 gay couples have applied to marry.
