Spermicide works by killing sperm. The copper IUD works by interfering with sperm motility.
Because if there is no sperm in the ejaculate there is no fertilization.
The barrier method
Not as far as I know. Even current attempts to create a birth control pill for men concentrate on killing the male sperm...not the female egg.
A condom would be a non-hormonal barrier birth control method.
Sperm is not affected by hormonal birth control; it does the same thing it does if you're not on birth control, except that there's some decrease in how much sperm can get into the uterus (due to thickening of the cervical mucus). Hormonal birth control affects the egg.
Yes, birth control can and does fail. The only 100% effective method of birth control is for eggs to not come into contact with sperm via either sterilization procedures or not having sexual intercourse.

Yes the pre ejaculation contains sperm. That is why the pull out method does not always work, and you still can get pregnant. So use condoms or another birth control method. There are many to choose from but you can still catch an std so condoms or abstain is your best method.
No, birth control pills taken on the first day are not immediately effective at killing sperm. It typically takes seven days of consistent pill use to provide contraceptive protection against pregnancy. It is essential to use alternate forms of birth control during this initial period.
If you're on Birth Control and using the Withdrawal Method then you're at the very least as safe as you would be on Birth Control. If you look at it as a percentage though... Less sperm in the vagina reduces the possibility of pregnancy and Birth Control lessens the possibility of Pregnancy as well. So, in effect, you're safer. -Note: The Withdrawal Method is not an effective form of contraceptive.
Dishwasher soap is not designed or recommended for killing sperm. It is best to use proper contraceptive methods or consult a healthcare professional for accurate information on birth control and pregnancy prevention.
