I'm talking about sterilization of humans... not cats and
dogs.
Would anyone opt to undergo such procedures? If so, would you do it
before or after you have kids of your own? If you're intending to
do it wihout having kids of your own, what are your reasons?
If you have no intention of having any of such procedures performed
on yourself, do you take a neutral stand or will you advise against
it strongly?
Religious issues aside, that
is.
And NO, don't think so much about why I'm asking this. 
edit: have to add that I am not fishing for information to do
homework

Sterilization is a surgical technique leaving a
male or female unable to procreate. It is a method of birth
control. For non-surgical causes of sterility, see
infertility.
Common sterilization methods include:
Vasectomy in males. (permanent,
irreversible)
The vasa deferentia, the tubes which connect the testicles to the
prostate, are cut and closed. This prevents sperm produced in
the testicles to enter the ejaculated semen (which is mostly
produced in the seminal vesicles and prostate). Although the term
'vasectomy' is established in the general community, the correct
medical terminology is deferentectomy, since the structure known as
the 'vas deferens' has been renamed the ductus deferens.
Tubal ligation in females. (intended to be
permanent, reversible in some cases)
Known popularly as "having one's tubes tied". The Fallopian tubes,
which allow the sperm to fertilize the ovum and would carry the
fertilized ovum to the uterus, are closed. This generally involves
a general anaethetic and a laparotomy or laparoscopic approach to
cut, clip or cauterize the fallopian tubes. Less commonly used is
the Essure office procedure of inducing scarring and occlusion of
the tubes by the effects of small pellets inserted by a catheter
passed through the cervix and womb.
Hysterectomy in females. (permanent,
irreversible)
The uterus is surgically removed, permanently preventing pregnancy
and some diseases, such as uterine cancer.
Castration in males. (permanent,
irreversible)
The testicles are surgically removed. This is frequently used for
the sterilization of animals, with added effects such as docility,
greatly reduced sexual behaviour, and faster weight gain (which is
desirable in some cases, for example to accelerate meat production
[more for animals]).
