Louisiana’s chemical castration law, codified at Louisiana Revised Statute 14:43.6, lets a sentencing judge order a convicted sex offender to receive ongoing injections of medroxyprogesterone acetate (MPA), a hormone that suppresses testosterone and is intended to reduce sexual urges. The order is discretionary on a first conviction for one of the covered offenses and mandatory on a second. The law has been on the books since 2008, and in 2024 the legislature added a separate statute authorizing surgical castration for certain crimes against children under thirteen.
Which Convictions Can Trigger Chemical Castration
R.S. 14:43.6 lists a specific set of offenses that make an offender eligible for an MPA order:
- First or second degree rape (formerly aggravated rape and forcible rape)
- Sexual battery, when the victim is under thirteen
- Second degree sexual battery
- Molestation of a juvenile, when the victim is under thirteen
- Aggravated crime against nature
A conviction for any offense outside this list cannot trigger an MPA sentence under 14:43.6, even if the conduct involved is similar.1Louisiana State Legislature. Louisiana Revised Statutes 14:43.6 – Administration of Medroxyprogesterone Acetate (MPA) to Certain Sex Offenders
First Conviction vs. Second Conviction
The difference between “may” and “shall” controls almost every case under this statute. On a first conviction for a listed offense, the judge decides. The court weighs the circumstances of the crime and the offender’s background, and many first-conviction cases end without an MPA order, particularly when the judge concludes other sentencing conditions are sufficient.
On a second or subsequent conviction for any of the listed offenses, the court has no discretion. An MPA order is required, and it stacks on top of the prison sentence, fine, and any supervision the offender receives. It does not replace or reduce them.
The one way out of mandatory MPA on a second conviction is for the offender to file a written motion electing permanent surgical castration instead. The election must be knowing and intelligent, and this provision has existed since well before the 2024 surgical castration law.1Louisiana State Legislature.

How the Injections Are Given
MPA is administered as an intramuscular injection on a recurring schedule set and monitored by the Department of Public Safety and Corrections. Clinical literature on sex-offender treatment indicates initial dosing typically starts around 400 mg per week, adjusted for the offender’s body size and clinical response, and usually tapers after roughly six months.
For offenders being released from prison with MPA as part of a parole treatment plan, injections must begin at least six weeks before the release date. Once the offender is in the community, parole or probation officers track compliance with the injection schedule, and the Department of Public Safety and Corrections coordinates with the medical providers.
The statute does not address who pays for the injections. Costs may be assigned to the offender in practice, but 14:43.6 itself is silent on financial responsibility.
What Happens If an Offender Refuses or Misses an Injection
Refusing an MPA injection or failing to appear for a scheduled appointment is a separate crime under R.S. 14:43.6. A conviction carries three to five years of imprisonment, with or without hard labor, and the sentence cannot be suspended or reduced through probation or parole.1Louisiana State Legislature. Louisiana Revised Statutes 14:43.6 – Administration of Medroxyprogesterone Acetate (MPA) to Certain Sex Offenders
There is no graduated warning system in the statute. A single missed injection or a single refusal is enough for prosecutors to bring a charge, and because it is a separate criminal case, the resulting prison time runs on top of whatever sentence the offender is already serving.
MPA as a Parole or Probation Condition
A second Louisiana statute, R.S. 15:538, authorizes MPA treatment as a condition of parole, probation, or a suspended sentence for offenders convicted two or more times of certain sex offenses. The treatment plan is developed through a mental health evaluation, and MPA or a chemical equivalent is identified as a “preferred method” of treatment.
The consequences for noncompliance under this pathway look different from the sentencing statute. Instead of a separate felony prosecution, failure to complete treatment is grounds for revoking the parole, probation, or suspended sentence, which sends the offender back to prison on the original conviction. Good-time credits already earned can also be forfeited.
An offender who voluntarily undergoes permanent surgical castration is exempt from the chemical treatment requirements under this parole provision.
The 2024 Surgical Castration Statute
In 2024 the legislature enacted R.S. 14:43.7, making Louisiana the first state in the country to authorize court-ordered surgical castration as part of a criminal sentence. The law took effect August 1, 2024.2Justia Law. Louisiana Revised Statutes Title 14 RS 14:43.7 – Administration of Surgical Castration for Certain Sex Offenders
Surgical castration under this statute reaches a narrower set of cases than chemical castration under 14:43.6. The offense must qualify as both a “sex offense” and an “aggravated offense” under the definitions in R.S. 15:541, the victim must be under thirteen, and the crime must have occurred on or after August 1, 2024. Sexual battery prosecuted under R.S. 14:43.1(C)(2) and second degree sexual battery are explicitly excluded from surgical castration eligibility, even though both can trigger chemical castration.2Justia Law. Louisiana Revised Statutes Title 14 RS 14:43.7 – Administration of Surgical Castration for Certain Sex Offenders
Surgical castration is always discretionary. The judge may order it but never must. A court-appointed medical expert has to find within sixty days of sentencing that the offender is an appropriate candidate for the procedure, and the statute explicitly bars the sentence when surgery is not medically appropriate. Offenders under seventeen are excluded entirely. For offenders sentenced to prison time, the surgery must be performed no later than one week before release.2Justia Law.

Refusing or avoiding the surgery carries the same three-to-five-year penalty as refusing MPA injections, prosecuted as a separate criminal case.2Justia Law. Louisiana Revised Statutes Title 14 RS 14:43.7 – Administration of Surgical Castration for Certain Sex Offenders
Health Risks of MPA Treatment
At the doses used for hormone suppression in sex offenders, MPA carries documented risks of serious cardiovascular events, including heart attack, stroke, and deep vein thrombosis. Blood clots can form in the legs and travel to the lungs. The medication is also associated with pancreatitis and with metabolic changes that compound heart disease risk, particularly in offenders who are overweight or who have diabetes or high cholesterol.
Other documented effects include significant weight gain, vision changes, and loss of bone density over time. Chest pain, sudden severe headache, slurred speech, difficulty breathing, and sudden loss of coordination are warning signs that require immediate medical attention. These risks continue for as long as treatment continues, which in some cases runs for years or indefinitely as a condition of release.
