Doctor Wisit Tungnaphakorn said the four clinics would face a probe after they were implicated by a man arrested in Nongkhai on Thursday while allegedly trying to smuggle six tubes of semen to Laos.
The suspect, Nithinon Srithaniyanan, said he had been receiving semen tubes in a frozen nitrogen tank from Jetanin, Superior ART, First, and I-Baby clinics in Bangkok to deliver them to VIP Clinic in Vientianne.
Wisit said he will hold a press conference in the afternoon after checking the four Bangkok clinics.
