Michael K. Laidlaw, M.D. is an academically trained, board-certified endocrinologist who has been in private practice in Rocklin, CA, since 2006. He has written extensively on the topic of harms from puberty blockers, opposite sex hormones and surgeries in locations such as California, Washington DC, the UK Parliament, and in front of the Florida Medical Board. He has worked and testified on behalf of states, including as an expert witness, for legislation to stop the use of harmful hormones, puberty blockers and surgeries provided to minors for gender transition.

We just had a great fourth of July in our corner of California, but I couldn't help thinking,
you know, what would the founders think about what's happening today? What would they think
if someone couldn't define what a woman is or what a man is, or that you could give chemicals
they didn't know about hormones to magically transform someone from a boy into an adult woman
or a girl into an adult man? Thank you. Again, I was first really took a deep dive into this when
this book, if you've heard of it, I Am Jazz, was read to kindergartners in our local school system,
and a parent urged me to read it as an endocrinologist, and this is a propaganda book
geared towards very young kids, kindergartners, and elementary school, and I found at least a
couple of things that were untrue claims in there, that a boy could be born with a girl's brain,
that a doctor could somehow diagnose a child as being transgender, and there was a lot of
information missing about types of medical harms that can happen with this treatment. So today,
I'm going to talk about what is gender dysphoria a little bit, how normal human sexual development
works, what is gender affirmative therapy, hormones and such, who are the major promoters, you've heard
a lot about that, I'll go through that a little bit, nations and states that have turned away
from this care, and about suicide, deaths, and a conclusion. What does all this hinge upon? I think
Dr. Grossman covered this well, objective biology versus subjective feelings. So gender identity is
an internal feeling of being a boy, a girl, or some variation. Gender dysphoria is a legitimate
psychological diagnosis found in the DSM-5, with an extreme discomfort with one's sex and perceived
gender, leading to significant distress and impairment of functioning, lasting at least six
months. And it's important to know that depending on which study you look at, so long as kids aren't
interfered with with hormones, the majority, 50 to 98 percent, will desist or grow out of this by
adulthood. Also important to know is that many of these people, as you've heard today, have other
coexisting psychological comorbidities, such as anxiety, depression, or autism, or self-harm. Now,
as an endocrinologist, I provide hormones to people. Hormones are very powerful medications
that alter body and mind. And so if I'm going to give insulin to a patient, I'm going to make sure
I have some objective evidence of diabetes. I want glucose results. If I'm going to refer a patient
for a thyroid cancer, I want a biopsy to show me for sure that this person needs this treatment.
So we're going to radically alter, as I said, people's bodies, kids' bodies, with hormones.
How can I prove that this person is transgender? Where do I find the gender identity? Can you do a
CAT scan, or an MRI, or chromosome testing, or other testing? And the answer is you cannot. Again,
there are only two sexes, in case you missed that earlier. Sperm comes from your father, an egg from
your mother, and there are no other gametes out there. There aren't 14,000 other gametes. There's
only two to make you and all of us. You can look in chromosomal evidence that's found in all cells
with nuclei in your body, an XX for a female, XY for a male, and these cause different processes
to occur, and sometimes in a sex-specific way within cells. During normal development, you
actually develop your reproductive track in organs around weeks 8 through 12, and so there
are primitive tubules. In the beginning, you have some that could become a male and some that could
become a female, but what happens is you develop into one or the other, and those other tubules are
completely eliminated, which means that you can go down one track or the other, but you cannot
cross tracks later. We don't have any medical way of doing that. Again, sex is identified at birth.
You can do it as an adult, as a four-year-old. They could look at their little brother or sister and
it's not assigned at birth. No one flips a coin or pulls out a lotto ball. This is a male or a
female. It's very easy to identify. There are people with disorders of sexual development,
which is outside of the scope of this and really not relevant here, but it doesn't make any
different sex. It's just a disorder of sex development. I'm going to talk about what I
call gender-affirmative therapy, which really has four phases, one or more of the social transition,
puberty blockers, cross-sex hormones or opposite-sex hormones, and surgical modifications,
which you'll hear more from Dr. Lappard. Doctors and pediatricians and doctors can examine patients
and find out what stage of pubertal development they're in by looking at what we call Tanner
stages. Tanner 1 is the undeveloped prepubertal person, and Tanner 5 is an adult, fully adult,
reproductive organs are present and fully developed. Stages 2 through 4 are various
in-between stages of development. It's important to know here for our purposes that around Tanner
stage 4, sometimes 3, that's when fertility is established. Now, all of this amazing process
is under the control of glands, one being the pituitary, which is a small piece-sized shape
organ in your brain. That activates the testicles to make testosterone or the ovaries to make
estrogen, and that rolls into place all the processes for developing puberty. Now, sometimes
persons can develop conditions where they have problems with this communication and it stops
puberty or they may not begin puberty, and this is diagnosed and treated by endocrinologists.
But other types of medications, such as Lupron, which you may have heard of, can also chemically
interfere with this process and stop puberty. Now, this has legitimate uses in central precocious
puberty for very young kids, say they're age 3 or 4, who go through puberty early, but there's no
FDA approval and there's no good evidence, as you've seen, for using this for the purpose of
gender transition. And as you might imagine, blocking puberty blocks this normal advancement
and normal advancement of fertility. So, different side effects of blockade of normal puberty.
In the male, you'll stunt penile and testicular growth, which makes future surgeries problematic.
Sexual dysfunction, as you might imagine, impairment of erection, orgasm, ejaculation,
prevention of sperm production. In both sexes, you'll have disruption of normal brain development,
which occurs under the influence of hormones, and disruption of normal bone development. In the
female, if you stop puberty at an early stage, as recommended by WPATH and Endocrine Society,
Tanner Stage 2, you'll develop an early menopause-like state with blockade of normal
breast development, decreased blood flow to vagina and vulva, sexual dysfunction with thinning
of vaginal epithelium, vaginal atrophy, anorgasmia, problems with orgasm, and, of course, interferes
with menstruation and infertility. And you'll hear more about infertility from Ms. Lal later.
You can also read labeling and note that there's many neuropsychiatric effects of puberty blockers
right on the labeling. And this is ultimately, for many, a pathway towards sterilization because
first you've impaired or perhaps destroyed sex organs with these medications, and then many,
particularly from earlier studies, go on to have their testicles or ovaries removed,
which is complete sterilization. Now, I just want to talk a little bit about bone development.
So, the pubertal phase and up through the 20s is an important time for developing bone and
bone density. And so, you can see at the bottom here, kids and adults ages and years and bone
density. And you can see a rapid increase in both males and females, you know, from a 10-year-old to
late 20 years. What happens with puberty blockers is that relative to their peers, they cannot put
down as much bone and end up with a lower bone density than you would otherwise expect. And so,
there's this flat lining of bone density, which is important because this can lead to risk of
osteoporosis and debilitating fractures when a person is older. Now, taking cross-sex hormones
after may mitigate some of these effects. But again, as you'll see, that is not a healthy way
to go either. Here is a female who had undergone mastectomy surgery. And you can see evidence of
what we call hyperandrogenism or high testosterone levels. You can see the abdominal hair, facial
hair. And I just want to show you, and I think this was covered earlier, but the normal female
range of testosterone, and females make testosterone as well, is 10 to 45, 10 to 50 in blue there. But
in the orange is what they're recommending for this gender transition, some 6 to 100 times higher
than normal female levels. And this leads to multiple risks, increased risk of heart attack
and death due to cardiovascular disease, high red blood cell counts, potential liver dysfunction,
as you heard earlier with Kayla, hypertension, various potential risks for the reproductive
tract, ovarian, breast, uterine cancer, some of that still being worked out. Of course,
hirsutism or hair growth, deepening of the voice, sexual dysfunction, infertility. This is a
controlled substance and it's being used off-label. And this is important because this is data from a
paper about the Food and Drug Administration adverse event reporting. And I want to note
the similarities to anabolic steroid abuse, in which we've written in a paper actually a comment.
So in the adverse event reporting, they found evidence of aggression, anger reported, euphoria,
depressed mood, dissociative identity disorder, affect-lability, emotional disorder, antisocial,
self-destructive behavior, homicidal ideation, suicidal ideation. And many of these are similar
as to what can be found in anabolic steroid abuse. Now let's talk about estrogen. Using estrogen in
very high doses, maybe 2 to 40 times higher than the normal estrogen levels of males. This leads to,
and Dr. Schwartz has a great paper and company about this, increased risk of, again, heart attack
and death due to cardiovascular disease, thromboembolism risk, 2 to 5 times increased risk of
blood clots, deadly blood clots, possible stroke risk, high triglycerides. The breast cancer risk
in males, and males can get breast cancer, has increased some 22 to 46 times, depending where
you look, benign tumors of the brain, prolactinomas, germ cell neoplasms, or other possibilities.
Endocrine Society is an otherwise legitimate medical organization. I have been a member since
2006. They do great work except in gender stuff. They wrote guidelines in 2009 and 2017.
Nine out of the 10 authors of this 2017 guideline were WPATH or WPATH-affiliated.
So I've often been asked, you know, why are medical organizations following, you know, this
sort of treatment? And I think it's because WPATH early on in 2009 got involved and recognized,
why not use the Hormone Association to legitimize what we're doing? Systematic reviews of evidence
have been done, and common themes in looking at this is that limited high-quality evidence for
most interventions, primarily low-quality, problems with methodology, small sample sizes,
lack of control groups, a lack of long-term follow-up, mental health benefits unproven.
And so many nations have turned away from this, including the UK. There's Dr. Hilary
Kass you heard about earlier. And we have our own HHS report, which is still under peer review,
but in many ways expands on the Kass report and is very extensive and worth a read.
I want to talk finally about death in this sort of treatment paradigm,
because that's the ultimate thing that physicians are trying to prevent. And now,
if you look at back in 2011, a study was published looking at the entire nation of Sweden,
general population compared to some 300-plus persons who had gotten hormones and surgeries.
And so you can see time in years across the bottom and survival with 100% at the top.
And the top two continuous lines are males and females in the general population. And if you
look at the dashed lines, that shows what they call trans males and trans females,
how their survival dropped off rapidly after 10 years. In fact, there was nearly three times the
all-cause mortality rate and 19 times the rate of completed suicide.
Now, what about children and young people? This is Dr. Johanna Olson-Kennedy,
who you heard about earlier, gender clinician and researcher at Children's Hospital Los Angeles. And
here's a quote you've heard what she tells parents. We often ask parents,
would you rather have a dead son than a live daughter? Which is quite a claim in a way.
It's a question, but it's also a claim that if your kid receives these hormones, they're going
to live, though they may be different gender than you had thought. And if not, they will die by
suicide, which if true, would be maybe an important way to discuss this. But if not true, it would be
seen as, in my opinion, extreme form of coercion. And Jane Robbins is attorney and author. She
alerted me early on to a study from the NIH, NIH-funded study. And we looked for more information
using FOIA requests to NIH. The title of this now 10-year NIH study is The Impact of Early
Medical Treatment on Transgender Youth. There's four sites, academic institutions across the
country. And so they were looking at two arms, a puberty blocker arm, starting puberty blockers
at a very early age, say eight for girls or nine for boys, and monitoring the effects over two
years. And also cross-sex hormones starting at age 13, though that was lowered later. And they
were studying mental health, psychological well-being, metabolical and physiologic parameters,
bone health, and so forth. Now, we found information on that around 2018. And in 2019, one of my
colleagues, Dr. Will Malone, who is also an endocrinologist, and my colleague Hachi Horvath
of epidemiology, wrote a letter to the Office of Human Resource Research Protections asking for a
moratorium on this study because of all the things I mentioned earlier, which would clearly happen.
We stated, we contend that neither children nor their parents can meaningfully consent to
permanent infertility or other potentially serious medical harms to treat a non-medical condition.
We question whether these parents were fully informed of the health risks or the possibility
of tragic regret. We received a reply from NIH basically stating that they would not have a
moratorium, that that would only stop the data collection in any ways these parents were informed
of what would happen, and they weren't going to do anything about it. Now, in 2023, a study was
published in New English Journal of Medicine with the cross-sex hormone outcomes, or at least some
of them, of 315 patients who were given this treatment of cross-sex hormones. And the most
common adverse event was actually suicidal ideation on 11 participants. And two kids or young people
actually died by suicide, which is, I thought, that's what we were trying to prevent with this,
weren't we? Now, in medicine, it's been common practice for centuries to do autopsies of patients,
especially people with rare or unusual conditions, and compare that with their clinical course during
life to advance what we know about different things. For example, adrenal insufficiency is
one thing I know about where they had done that. So in the New England Journal, what did you find
about these deaths? Well, nothing really. It's just a statistic. Were they males or females? We don't
know. What were their ages? We don't know. What were their psychological care leading up to that?
What were their diagnoses? Were autopsies performed on the study subjects? If not, why not?
What were their testosterone levels, or estrogen, or progesterone, or blood levels? What did the
first responders' reports say? None of this is known at this time, so information is being concealed,
in my opinion, and so the first participant was enrolled in this study in 2016. We wrote our
letter in 2019, and then the New England Journal published this data in 2023, and I was quite
surprised because we had been following yearly progress reports and never found, I never saw,
that death was mentioned. So it was concealed until our wonderful attorneys in the state of
Alabama subpoenaed HHS documents in late 2023 and found out the first death actually occurred
way back in 2017, before we had written our letter, and I could not find any information
about the second death. Now, someone we do have information about, many of you probably know about,
Jallie Martinez and her mom, Abigail Martinez. The only reason we know about her case is because
her mom has been very outspoken about it. Jallie had depression. She was referred to
for gender transition at Children's Hospital Los Angeles because of a school psychologist who said
that she needed gender transition, and she was administered testosterone. Her mother relates
that the daughter was taken away by the county and placed into foster care. She committed
suicide by train in Los Angeles County at age 19. The mom says around 9 30 p.m. that night, she walked
in front of the train tracks, facing a train. She went on her knees, raised her arms up, and just
laid on the tracks. So, if you want to find out more information of a case report, you could look
in your medical journals, right, and find that. No, but you can do a public record request to Los Angeles
County Coroner's Office, which is what I did, and found the record. And I don't want to be graphic here,
but you can get a picture of it from here. She was identified as a 19-year-old female.
Importantly, she had scars on both arms. This was not from a train collision. These were old healed
scars from her history of self-harm, and her body was so badly destroyed that mom wasn't even allowed
to see the child afterwards. So, we'd like to prevent that from happening. We'd like to prevent
other deaths from happening. We'd like to prevent all of the stories we've heard today of young
people being severely injured or mutilated from this treatment. Just to know, this is not
standard of care. I skipped over that slide, but Endocrine Society even said it. We don't have the
technology to turn girls into boys, boys into girls, so kids may believe it. Medications are being
used off-label at high doses without proper FDA risk assessment. Multifold harms are evident or
predicted. Proper long-term studies haven't been done. Multiple systematic reviews of evidence have
found poor quality of evidence of benefit. Young people have been permanently maimed and killed
during the course of these treatments. And finally, the WPATH Standards of Care 8 is an extreme
document, presents a grave danger to minors, and should not be followed by any clinician or physician. Thank you.
