EXPLANATORY NOTE 
The number of rape cases and other sexual offenses has been 
alarmingly increasing, despite enforcement of more stringent laws 
enacted in recent years. In fact, statistics show that a considerable 
percentage of death sentences imposed are rape-related. 
Given the inability of the justice system to control rape and child 
molestation, there is a need to come up with measures, which in other 
countries, have proven to be effective in combating rape and other forms 
of sexual offenses. 
One of these measures is castration. 
Castration can be an ideal punishment for sex offenders. In fact, 
with surprisingly little fanfare, four states in the United States recently 
passed laws calling for castration - either chemical or surgical - of sex 
offenders. 
Florida, California, and Montana have all enacted more 
stringent laws to order involuntary chemical or surgical castration of 
these criminals. 
The Czech Republic and Germany have likewise introduced 
castration in a much more seemingly humane form, although only 
among sex offenders who volunteer for treatment. 
Castration is not actually a recent innovation. 
Compulsory 
castration, for instance, has been used as a punishment for crimes in all 
cultures dating back thousands of years. In Europe in the Middle Ages, 
the “eye for an eye” philosophy of jus talionis included castration as 
punishment for adultery or rape. In the 20th century, castration has 
been practiced in the Netherlands, Germany, Estonia, Iceland, 
Switzerland, and Scandinavia for rape, pedophilia and homosexuality. 
The technology for castration has evolved cansiderably, and there 
is evidence that, in some circumstances, it can dramatically reduce the 
likelihood a sex offender will strike again. 


More recently, research has produced powerful drugs, such as 
cyproproterone and medroxyprogesterone, which reversibly block 
testosterone production. The drugs’ primary use in men is to control 
prostate cancer, but when injected daily or weekly they reduce 
testosterone to castration levels. 
Surgical castration is less mutilating than it once was. 
Orchiectomy, as it is called is a day-surgery procedure done under local 
anesthesia. Each testicle is removed through a small scrotal incision 
similar to the kind made during a vasectomy. 
* 
In the US, castration laws are enforced with some variations. 
Florida requires judges to impose either injections or orchiectomy for 
repeat rapist. 
California does the same, 
but only for repeat child 
molesters. 
Montana allows, but does not require, judges to impose 
chemical castration on offenders who commit rape or incest after even 
one offense, if it is particularly heinous. 
The justification over the imposition of castration as a form of 
penalty is that it controls sex offenders’ irresistible urges to rape or 
molest again. Studies of the European experience would reinforce this. 
Of more than 700 Danish sex offenders castrated after multiple 
convictions, relapse rates dropped from between 17 percent and 50 
percent to just 2 percent. 
A Norwegian study showed the same for selected male and female 
sex offenders (the women had their ovaries removed). In smaller studies 
of cyproproterone in Scandinavia and Italy, chemical castration was 
equally effective in some groups of volunteer prisoners, with the most 
dramatic reductions among pedophiles. 
These studies suggest the common argument - that rape is all 
about power, not sex, and therefore castration won’t work - is wrong. 
Interestingly, a German study found that up to half of the castrated men 
still could have erections and sex, but their desire was weakened or even 
extinguished. Over 80 percent no longer masturbated while 70 percent 
gave up sex. 
Given all these developments, the proposed measure aims to 
mandate castration for sex offenders with the end view of achieving the 
same result. 
‘ 
Immediate enactment of this bill is earnestly sought.
