104TH GENERAL ASSEMBLY
State of Illinois
2025 and 2026
HB4482

Introduced 1/20/2026, by Rep. William E Hauter

SYNOPSIS AS INTRODUCED:

New Act

Creates the Prohibition on Gender Reassignment Procedures Act. Sets
forth findings. Defines terms. Provides that a health care provider shall
not perform or offer to perform on a minor, or administer or offer to
administer to a minor, a medical procedure if the performance or
administration of the procedure is for the purpose of: (1) enabling the
minor to identify with, or live as, a purported identity inconsistent with
the minor's sex; or (2) treating purported discomfort or distress from a
discordance between the minor's sex and asserted identity. Provides for a
private right of action for a minor or a parent of a minor that was injured
as a result of the Act and a right of action for the Attorney General.
Provides that a violation constitutes a potential threat to public health,
safety, and welfare and emergency action shall be taken by an alleged
violator's appropriate regulatory authority. Provides that a minor upon
whom a medical procedure is performed or administered must not be held
liable for violating the Act. Makes other changes.

A BILL FOR

HB4482
LRB104 14836 AAS 27980 b
1

AN ACT concerning regulation.

2

Be it enacted by the People of the State of Illinois,
3
represented in the General Assembly:

4

Section 1.
Short title.
This Act may be cited as the
5
Prohibition on Gender Reassignment Procedures Act.

6

Section 5.
Findings.
The General Assembly finds the
7
following:
8

(1) The General Assembly must take action to protect
9

the health and welfare of minors.
10

(2) Medical procedures that alter a minor's hormonal
11

balance, remove a minor's sex organs, or otherwise change
12

a minor's physical appearance are harmful to a minor when
13

the procedures are performed for the purpose of enabling a
14

minor to identify with, or live as, a purported identity
15

that is inconsistent with the minor's sex or treating
16

purported discomfort or distress from a discordance
17

between the minor's sex and asserted identity. These
18

procedures can lead to the minor becoming irreversibly
19

sterile, having an increased risk of disease and illness,
20

or suffering from adverse and sometimes fatal
21

psychological consequences. Moreover, the General Assembly
22

finds it likely that not all harmful effects associated
23

with these types of medical procedures when performed on a

HB4482
- 2 -
LRB104 14836 AAS 27980 b
1

minor are fully known as many of these procedures, when
2

performed on a minor for such purposes, are experimental
3

in nature and not supported by high-quality, long-term
4

medical studies.
5

(3) There is evidence that medical procedures that
6

alter a minor's hormonal balance, remove a minor's sex
7

organs, or otherwise change a minor's physical appearance
8

are not consistent with professional medical standards
9

when the medical procedures are performed for the purpose
10

of enabling a minor to identify with, or live as, a
11

purported identity inconsistent with the minor's sex or
12

treating purported discomfort or distress from a
13

discordance between the minor's sex and asserted identity
14

because a minor's discordance can be resolved by less
15

invasive approaches that are likely to result in better
16

outcomes for the minor.
17

(4) Medical procedures are being performed on and
18

administered to minors in this State for such purposes,
19

notwithstanding the risks and harms to the minors.
20

(5) Dr. John Money, one of the earliest advocates for
21

performing or administering such medical procedures on
22

minors and a founder of the Johns Hopkins Gender Identity
23

Clinic, abused minors entrusted to his care, resulting in
24

the suicides of David and Brian Reimer.
25

(6) Such medical procedures are being performed on and
26

administered to minors in this State with rapidly

HB4482
- 3 -
LRB104 14836 AAS 27980 b
1

increasing frequency and supposed guidelines advocating
2

such treatment have changed substantially in recent years.
3

(7) Minors lack the maturity to fully understand and
4

appreciate the life-altering consequences of such
5

procedures and many individuals have expressed regret for
6

medical procedures that were performed on or administered
7

to them for such purposes when they were minors.
8

(8) Many of the same pharmaceutical companies that
9

contributed to the opioid epidemic have sought to profit
10

from the administration of drugs to or the use of devices
11

on minors for such purposes and have paid consulting fees
12

to physicians who then advocate for the administration of
13

drugs or the use of devices for such purposes.
14

(9) The integrity and public respect of the medical
15

profession are significantly harmed by health care
16

providers performing or administering such medical
17

procedures on minors.
18

(10) This State has a legitimate, substantial, and
19

compelling interest in the following: (1) protecting
20

minors from physical and emotional harm, (2) protecting
21

the ability of minors to develop into adults who can
22

create children of their own, (3) promoting the dignity of
23

minors, (4) encouraging minors to appreciate their sex,
24

particularly as they undergo puberty, and (5) protecting
25

the integrity of the medical profession, including by
26

prohibiting medical procedures that are harmful,

HB4482
- 4 -
LRB104 14836 AAS 27980 b
1

unethical, immoral, experimental, or unsupported by
2

high-quality or long-term studies, or that might encourage
3

minors to become disdainful of their sex.

4

purported discomfort or distress from a discordance between

HB4482
- 6 -
LRB104 14836 AAS 27980 b
1
the minor's sex and asserted identity.
2

(b) It is not a violation of this Section if a health care
3
provider performs or offers to perform a medical procedure on,
4
or administers or offers to administer a medical procedure to,
5
a minor if:
6

(1) the performance or administration of the medical

9

(2) the performance or administration of the medical
10

procedure on the minor began prior to the effective date
11

of this Act.
12

The minor's treating physician must certify in writing
13

14
upon the facts known to the physician at the time, ending the

medical procedure would be harmful to the minor. The
16

parent of a minor, consented to the conduct that constituted

14
enabling the minor to identify with, or live as, a purported
15

violation on behalf of the minor.

and both of the following are met:
19

(1) the minor's death is the result of the physical or

2
this Section must be liberally construed to effectuate its
3

8
that end, this Section is severable.

16
procedure, and recover a civil penalty of $25,000 per
