NEUTERSOL™ PEDIATRIC

Congratulations on your purchase of Neutersol™ Pediatric, the safe, 
painless, and inexpensive way to perform home castration of boys from 
one year of age to the beginning of puberty.  Neutersol™ Pediatric 
has been approved for non-prescription sale to perform home 
castrations.  It is a safe, inexpensive alternative to surgical 
castration by a physician either at his office or in a hospital.  No 
special care is required after castration, and, unlike surgical 
castration, the boy may resume his normal activities immediately 
following the procedure.  

The active ingredient found in Neutersol™ Pediatric has been used 
successfully for several years by orphanages and other institutions 
in countries around the world for the castration of young boys.  The 
only side effects noted to date have been a slight tenderness of the 
testicles for a day or two after treatment in about two percent of 
boys who have been castrated with Neutersol™ Pediatric.  Testicles 
turn soft and completely disappear within one to two months, 
depending on their size at the time of treatment. Since chemical 
castration is painless, leaves no scars, and the testicles disolve 
gradually, younger boys may not even realize that they have been 
castrated until they are older and someone points out that they have 
no testicles.   

WARNING:  
Before using Neutersol™ Pediatric on any boy after his eleventh 
birthday, you should consult a doctor to make certain that he has not 
yet entered puberty.  Once puberty has begun, most commonly not until 
the twelfth year,  Neutersol™ Adult should be used instead.  The 
changed homones within the testicles require a different formulation 
for them rapidly to wither and disolve.  Use of Neutersol™ Pediatric 
on a testicle which has entered puberty will be much less effective 
than the use of the Neutersol™ Adult formula.  Please read the 
information at the bottom of this sheet before purchasing Neutersol™ 
Adult for any home castration.  It provides essential information 
about selecting the appropriate size home castration kit for your 
use.  

INSTRUCTIONS FOR USE:
Neutersol™ Pediatric is simple and easy to use.  It requires less 
than 30 minutes to castrate a young boy, including all preparation 
time.  The procedure may easily be performed by any adult with no 
prior training.  Please read the instructions through completely and 
make certain that you understand them before beginning the 
castration.  

1).  The castration should, ideally, take place in a very warm room.  
85° to 95° will provide the best results.  If a cooler room is used, 
an electric hot pad may be used, if necessary, to properly relax the 
scrotum (the skin sac holding the testicles).  The boy to be 
castrated should be undressed and placed on a bed or table with his 
legs dangling over the edge.  It is usually easiest for you to stand 
between his legs to perform the castration.  For younger boys, it may 
be helpful to have another adult present to hold the boy steady as 
you castrate him.  

2).  If the room is cool and the boy’s scrotum is holding the two 
testicles too tightly against his body for you to be able to grasp 
them easily, an electric hot pad may be draped over the lower body 
for a few minutes to relax and loosen the scrotum.  You should be 
able to put your index finger and thumb around the base of the 
scrotum and stretch the skin tightly over the two testicles so that 
they can be held steady as you work.  

3).  Once the boy is properly positioned and ready to be castrated, 
tear open the plastic safety wrapping and place the enclosed plastic 
tray with the two Neutersol™ Pediatric syringes where you can reach 
them easily while you perform the castration.

4).  Take the boy’s scrotum and testicles in one hand and stretch 
them so that you can easily stick the needles through the skin of the 
scrotum into both of the testicles.  

5).  Take one of the syringes with your other hand and,holding the 
barrel between your thumb and fingers, push the needle full length 
into the center of one of the testicles.  The needle should be pushed 
in as far as possible in one smooth movement.  The needle is the 
right length to put the Neutersol™ Pediatric formula near the center 
of the testicle.  

6).  Depress the plunger on the syringe to inject its entire contents 
into the center of the testicle.  Remove the needle.

7).  Using the other syringe, repeat steps 5 and 6 with the other 
testicle.  

8).  OPTIONAL:  Briefly massage the scrotum and testicles.  This 
helps both to minimize any discomfort from the needle pricks and to 
speed the process of dissolution of the testicles.  

9).  Replace the two syringes in the plastic tray and slide them into 
the box for easy and safe disposal.

10).  Congratulations, your home castration is now complete and the 
boy may dress and return to any normal activities.  You should check 
the progress of the castration in two or three weeks by massaging the 
testicles.  They should feel soft and mushy and have no pain 
sensations.  Depending on their size, they will completely disolve 
and disappear in one to two months.  Should either testicle remain 
firm and sense pain after two weeks, you can either repeat the 
chemical castration with Neutersol™ Pediatric or ask your physican 
to perform a surgical castration of the boy.  Properly injected, 
Neutersol™ Pediatric has a failure rate of less than one boy per 
thousand.  




Selecting the proper size NEUTERSOL™ ADULT for home use

Once a boy enters puberty, the hormonal content of his testicles 
changes and you will need to use Neutersol™ Adult formula.  To 
castrate any boy after his eleventh birthday, you should first have 
him examined by a physican or school nurse to determine if he has 
begun puberty.  If he has (or for adult castrations), please read the 
following to help you choose the proper size Neutersol™ Adult home 
castration kit for your use.  

Neutersol™ Adult comes in three sizes to properly disolve testicles 
of different sizes.  They differ both in the length of the needle to 
reach the center of the testicle and the amount of Neutersol™ Adult 
in the syringe.  Each is designed for optimum castration of a range 
of testicle sizes.  If you are uncertain of the size of the testicles 
of the older boy or adult male whom you wish to castrate, you can 
purchase an inexpensive Testimeter™ at any drug store which carries 
Neutersol™.  

The Testimeter™ consists of a soft plastic rod with several 
testicle-shaped beads molded on it.  These can be compared to the 
size of the testicles which you want to remove in order to determine 
whether you need to purchase the Youth, Regular, or Large size 
Neutersol™ Adult home castration kit.  

 The five plastic testicles on the Testimeter™ are 6, 12, 15, 20, 
and 25 cc. in size.  The Youth size kit of Neutersol™ Adult is used 
to disolve testicles up to 15 cc in size and is most frequently used 
to castrate boys from about 12 to 15 years of age.  The Regular kit 
is for testicles from 12 to 25 cc and is used for most adults and for 
some boys as young as 13 or 14 whose testicles grow faster than 
normal. The Large kit should be used for testicles over 20 cc.  The 
overlapping sizes allow both for less needed accuracy in measurement 
and for the slightly different sizes of the two testicles.  

Boys usually begin puberty with testicles that are 4 to 5 cc in size 
and their testicles usually reach 15 cc by about the age of 14 or 15 
years.  A few adult males will have testicles in this smaller size 
range and also require use of the Neutersol™ Adult home castration 
kit in the Youth size.

Most adult testicles are 12 to 25 cc in size, as are those of some 
older boys.  They require the Regular size home castration kit.  The 
Regular size may be used for all adult home castrations, although you 
will have better results with the appropriate size of Neutersol™ 
Adult.  

Less than one quarter of adult males have testicles larger than 25 cc 
in size, some as large as 30 cc or more.  They require the 
Neutersol™ Adult home castration kit in the Large size for a quick 
and efficient castration.

Neutersol™ Adult is as simple and easy to use as Neutersol™ 
Pediatric and the instructions are the same as those above.  Larger 
testicles may require as long as three months to completely disolve, 
however.  Both adult male testicles and those of older boys will 
continue to produce viable sperm for a month or longer as they 
disolve.  If you require a quicker sterility with your adult 
castration, surgery is still recommended over chemical castration for 
any male old enough to begin producing viable sperm.  

If you have any questions about the use of this product, please call 
the Neutersol™ hot line at 1-888-CASTRATE  (227-8728).  Operators 
are on duty 24 hours per day to help you with any questions about 
your home castration.  

We appreciate your purchase of this Neutersol™ product and hope that 
you will again choose Neutersol™ for your next home castration.
