In what lawyers are describing as an attack on LGBTQ rights in Russia, gay men who have fathered children with surrogate mothers face arrest as part of an investigation into child trafficking.

Surrogacy is legal in Russia but has come under fire from conservative lawmakers and the Orthodox church. Police arrested a number of fertility doctors earlier this year and have accused them of “child trafficking” in an ongoing case.

State news agency TASS recently quoted an unnamed official saying that investigators intend to widen their investigation into surrogacy to include single fathers, whom the official assumed would be gay.

“They are planning to arrest more suspects, including single Russian men who used surrogate mothers to have babies,” the official said, claiming it was illegal for gay men to have children in this way.
