From original NYT piece that much of linked article in OP was sourced.
"Perfect Fertility Center, or P.F.C., a surrogacy agency registered in the British Virgin Islands, showed rare sympathy for L.G.B.T.Q. intended parents, promising babies via Cambodia, Mexico and the United States. The company’s website is illustrated with photos of same-sex couples cradling babies.
P.F.C. was founded by Tony Yu, who turned to Cambodian surrogates for his own children. Mr. Yu, who is openly gay, said Cambodian lawyers assured him that his agency was legal.
It was a multinational operation that spanned continents. Mr. Yu partnered with a fertility clinic in Phnom Penh run by a Vietnamese person. There, a German fertility specialist trained Cambodian doctors. An Indian logistics expert flew in with eggs harvested from donors.
In 2017, Mr. Xu signed a contract with P.F.C., agreeing to pay $75,000 for surrogacy in Cambodia, according to documents reviewed by The New York Times.
Mr. Xu visited Ms. Hun Daneth at the luxury villa. He told her that the egg donor was a Russian model, and he later showed Ms. Hun Daneth and her husband photographs of a white woman with wavy hair standing next to a sports car.
Mr. Yu, the agency founder, said that many of its egg donors came from Russia, Ukraine and South Africa. The intended fathers were Chinese, and many were gay.
“Mixed-race children are popular with our clients,” said Mr. Yu."
Long story short for Chinese or other Asian men (gay only?) and perhaps straights as well bi-racial children are the "in" thing.
Eastern European men and women are known for their physical beauty. It is one reason white Western Europeans, Americans and others who want "white" children turn to Ukraine or Russia as first choice if they cannot afford or get to USA.
Part of the work of hunky Richard B. Vaughn, Esq, also involves matching egg donors to couples (gay and straight) or singles (ditto).
NPH, Lance Bass, Andersen Cooper, along with many others who use surrogates don't necessarily want that woman's gene pool. They would be happy enough if say a black woman carried their child to term and gave birth, but actual eggs often come from another woman, and she is usually white/European.
Gays of course must use an egg donor from somewhere since there isn't a female "spouse" or whatever to provide eggs for in vitro fertilization.
