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]).(above extracted from Wikipedia)
