But that's different than freely choosing transition knowing it will lead to loss of fertility. They made that choice, it is not a doctor's job to predict with certainty where your mind will be in the far future.

How can someone "freely choose" to lose their own fertility when they are still a child, tween or teenager?

It's the same logic that doctors use to misogynistically deny tubal ligation or hysterectomies to young women. No other condition is treated this way as far as I know, nowhere else do we withhold treatment just because of the mere possibility of regret.

But there are many reasons why doctors are cautious in these situations; it's not just a matter of misogyny. Fact is, lots of women who don't want kids in their teens and 20s decide differently when they are older. I personally didn't want children until I was 33. Also, hysterectomy is a major operation with myriad lifelong impacts on women's health.

You are totally wrong about no other conditions being approached with so much caution. Most medical practitioners and health insurance companies require patients to try all the treatments that are the least radical, least invasive, least costly, with the lowest rates of negative effects first - and only if they have ALL failed to bring about marked improvement is the patient allowed to try more radical, invasive and risky approaches. Even in cases where life is at risk, such as cancers, doctors advise and use caution when it comes to treatments that can leave a young person infertile. Even when people are in the end stages of terminal illness, caution is exercised about using drugs and other interventions that are unproven and have many negative "side effects."

People can change their mind, so what? That can literally happen with anything, they should take responsibility for their choices. If they chose not to bank sperm years ago when they had the option then that's no one's fault but their own.

But what about all the people who will never get the option to bank sperm or retrieve and freeze eggs because their parents and doctors decided to use drugs to halt their development before they reach the age when they are able to make sperm - or to make mature ova?

Are you really so cruel that you would tell Jazz Jennings or Trinity Neal, "So what? You made your choices. It's no fault but your own." Do you really think they should take responsibility for what was done to them when they were 11 and 12? Jazz and Trinity were were forced into adopting a trans identity as toddlers and put on "blockers" at Tanner Stage 2. Do you seriously think they freely chose what was done to them? BTW, now that Trinity's two younger male siblings have also been decreed trans by their mom, they're probably going to be put on "blockers" as soon as they start puberty - and mom will probably arrange for them to have their testicles removed and penises reconfigured at 16, the age when she had it done to Trinity. You really would tell these people when they grow up and have misgivings to suck it up because in your opinion, having healthy genitals and being able to enjoy sex not only are unimportant, but they make YOU personally uncomfortable - and as YOU see it, being able to reproduce is not only over-rated, the very thought of having children makes YOU "want to vomit." Then once the knife is in, are you going to twist it further by pronouncing that what happened to them as children was their own their fault anyways?

I don't see you rushing to try and prevent people from making literally any other kind of choice they might regret later, so you shouldn't for people transitioning either.

You have no idea what I do in my life, LOL. But as someone who has raised children, and been in education, I definitely have shared information and offered the benefit of my experience (and wisdom) in hopes that it would help stop some others from doing things to their bodies that they might regret later. As a parent, I also had to say "no" when an adolescent child who needed surgery for a health problem was in such a rush to get the health problem fixed right away that he wanted to go with the first surgeon we consulted who could do it - even though that surgeon was a) not well qualified; and b) would have used a radical surgical approach that was experimental, without an evidence base, and likely would have led to diminished sexual function. I had to put my foot down and tell my child that when you get medical care, you get second opinions - and when you get surgery you go to the very best surgeon you can find, even if this means waiting a while, extra expense and the inconvenience of traveling. In my own case, when I had a serious problem with chronic gynecological/pelvic pain, I traveled 3,000 miles to get surgery from the best specialist in female pelvic pain and endometriosis I thought there was - David Redwine.

As a parent, I have also taken action more times that I can count to prevent my children - and their friends when in my care - from making many other kinds of choices I thought they might regret later on. Such as putting things in their mouth they could choke on, eating all their Halloween candy in one sitting, snorting soda pop up their noses, not doing their homework or leaving their homework to the last minute, not studying for exams, refusing to brush their teeth, getting behind the wheel of a car when drunk or stoned, watching horror movies when high on hallucinogens, joining the military, running off and eloping, not using contraception when engaging in heterosex, being cavalier about STDs, trying out heroin to see what it's like to shoot up, agreeing to cockamamie plans and schemes their friends cooked up, blowing all their hard-earned wages on passing pleasures and cheap thrills, getting a lot of visible tattoos/ink sleeves, investing money in dodgy ventures, getting involved romantically with people they only met online who might have been catfishers, and engaging in activities things that can impair male fertility.

young trans women may be able to receive a womb transplant in the future which could also eliminate the need to bank sperm at all

Huh? Even if someone did somehow implant a uterus in a human male body, and the person wanted to try to use that uterus to gestate a child, pregnancy still would require the merging of male and female gametes. So if such a person didn't bank their sperm, they'd need to get both eggs AND sperm from other people. I don't get why someone such as yourself would want to become pregnant with a child who is not biologically related to them. Were you under the impression that uteruses come stocked with eggs?

Also, even if someone male did manage to get a uterus implanted, and got doctors to create embryos via IVF, there's no way a pregnancy could occur and be successful. First of all, how exactly would the embryo(s) get inside the uterus? Where would the uterus get the signals and biochemicals needed to create the new lining, and bring about all the changes in the uterine tissue and environment, to allow for implantation and the development of a placenta? No way that a pregnancy could come about, much less continue to full viability, without female genes, female immune function, a female endocrine system, female kidney function, a female pelvis and skeletal structure, female internal anatomy, etc. Even if a male pelvis could somehow accommodate the size of a uterus as it grows over the course of pregnancy, a male circulatory system and male kidneys could not handle the job of processing and cleansing all the extra fluid volume.

The considerably larger size of the other male organs - and the way they are suspended inside the abdomen and torso - would get in the way of the expanding uterus, too. One of the reasons women have much smaller hearts, lungs and livers is to allow room for pregnancy - and our internal organs are more mobile than male internal organs are too, which allows them actually to move out of the way of the growing uterus when we are pregnant.
