Estrogen in men?
Estrogen is commonly known as a ‘female’ hormone. However, men also manufacture estrogen. Does this make men confused about their sexuality? Christopher S. from the United States writes:
My Dad recently engaged my Aunt in a discussion on homosexuality. My Aunt said that because men have an X and Y chromosome they are torn in their sexuality and also because men have estrogen. I gave many examples as to why this is wrong, however I wanted a more I informed position. I am extremely sorry to have bothered CMI. I appreciate your work. If there is anything I can do to help CMI, please let me know. God bless and keep your eyes on Jesus.
CMI’s Shaun Doyle responds:
Regarding your aunt’s ‘men having X and Y chromosomes makes them sexually confused’ argument, there are a number of problems with it. First, if having an X and Y chromosome made one confused about one’s sexuality, why wouldn’t all men be sexually confused? Regardless of the definition used, only a very small percentage of men would be ‘confused’ about their homosexuality. As such, your aunt’s statement is empirically false.
Second, what about biologically ordinary women who have two X chromosomes? There are lesbians, biological women pretending to be men, and women whose self-described sexual identity changes over time. And there would no doubt be women who would be unsure about their sexual identity. Are any of these women less confused than men?
Finally, just because men have an X chromosome does not make them ‘half woman’. Among many other important things, it means they can procreate and produce female offspring. The X chromosome houses a number of genes essential to human survival, and since men are humans, men need the X chromosome.
On her other point, do men produce estrogen? Yes, but it is not because men started off as women (men have, after all, had the male XY sex chromosome condition since fertilization). Rather, estrogen is an important hormone for men to have, and it’s even important for male reproductive function!1 The idea that estrogen is a ‘female hormone’ was refuted 20 years ago.
Furthermore, females produce the ‘male’ sex hormone, testosterone. So, if estrogen in males causes them to be confused about their sexuality, why does not testosterone in females do the same? These notions are devoid of scientific merit.
God created mankind both male and female (Adam and Eve), and He did not design us with a built-in propensity to be confused about whether we are male or female.
