The Wall Street Journal challenged the gender binary ideology that sex is on a spectrum beyond male and female.
"In humans, reproductive anatomy is unambiguously male or female at birth more than 99.98% of the time, said biologists Colin M. Wright and Emma N. Hilton in a WSJ op-ed published on Friday.
The biologists affirmed that the purpose of males and females is to reproduce.
"The evolutionary function of these two anatomies is to aid in reproduction via the fusion of sperm and ova. No third type of sex cell exists in humans, and therefore there is no sex 'spectrum' or additional sexes beyond male and female. Sex is binary."
LGBT+ groups insist sex is non-binary and there are multiple genders and sexes beyond male and female.
The Wall Street Journal writers said there is a "dangerous and anti-scientific trend toward the outright denial of biological sex," which sees male and female as "arbitrary groupings."
They added that "intersex individuals are extremely rare, and they are neither a third sex nor proof that sex is a 'spectrum' or a "social construct."
Referring to children who believe they are the opposite sex, researcher Jane Robbins said, "The concept of changing one's biological sex is, of course, nonsense."
She said "sex is determined by unalterable chromosomes."
"An individual can change his hormone levels and undergo surgery to better imitate the opposite sex, but a male on the day of his conception will remain a male on the day of his death."
The Wall Street Journal's op-ed said the current ideology driven approach to human sexuality often results in real-life damage to the most vulnerable members of society.
