Uterus Transplant - Tumblr Posts
Not to mention that there are some incredibly deserving women who for one reason or another cannot use their own uterus to get pregnant. It's known as Absolute Uterine Factor Infertility and Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome and cervical cancer early on in adulthood are two of the leading reasons it may occur. And a few important points that people don't seem to understand:
Every successful uterus transplant thus far has involved the recipient having their own ovaries. You need ovaries in order to menstruate or get pregnant. Trans women do not have ovaries.
Almost all, if not all, of the successful births following transplant, were using uteri from women who had previously had a child. Which just makes sense. If you are going to do a complicated surgery to provide someone with a uterus that they can use to get pregnant, better to pick a uterus that has a good track record. So the idea that you can just "donate your uterus" to anyone, including trans women, because you "don't want children" is not really a thing.
We JUST performed the first successful transplantation followed by childbirth in 2014. That's not even ten years ago. This field has so much more to learn in the next few decades.
Uterus transplantation's primary focus will be helping infertile women, because our bodies already have all the rest of the gear you need to have a child. An example of this would be how the pregnancy hormone lactin prepares a female's body to begin lactation when the infant is born, producing a very specific pre-milk called colostrum. Among this substance's many benefits are boosting a neonate's immune system and helping to fight infection. (My mom, who works in a NICU, calls this substance "liquid gold" because it makes such a big difference if an infant can be provided with it). This is something that biological males, even with a uterus transplant, would not be able to produce. Everything from where are bladders are located to how our pituitary glands work are different in biological women than in biological men, and affected greatly in terms of fertility and pregnancy.
While having children is certainly a choice, there is only one sex who is able to get pregnant, because we have fucking amazing bodies that know how to build human beings. I get that men are jealous of that ability, but they can get tf over it because they will never be able to do what we can do.
