fine... i'll spell it out for all the fucktards who are too stupid to use the mass abundance of resources around you. this is the
less technical version.

here to see the version for retards like you.
this info is from
http://en.wikipedia.org specifically articles that can be found from the
Contraceptives article.
how an "egg" is made
Quote
Ovarian follicles are the basic unit of female reproductive biology, they are roughly spherical aggregations of cells found in the ovary. They contain a single oocyte (aka ovum or egg). These structures are periodically initiated to grow and develop, culminating in ovulation of usually a single competent oocyte.
Quote
The follicular phase (or proliferative phase) is the phase of the estrous cycle, during which follicles in the ovary mature. It ends with ovulation. The main hormone controlling this stage is estradiol.
Quote
Ovulation is the process in the menstrual cycle by which a mature ovarian follicle ruptures and discharges an ovum (also known as an oocyte, female gamete, or casually, an egg)
how female oral contraceptives ("the pill") work
chance of still getting pregnant
- Perfect use -- 0.3%
- Typical use -- 8%
Quote
prevention method #1
Combined oral contraceptive pills were developed to prevent ovulation by progestogenic and estrogenic suppression of gonadotropin release. Combined hormonal contraceptives, including COCPs, inhibit follicular development and prevent ovulation as their primary mechanism of action.
Quote
prevention method #2
A secondary mechanism of action of all progestogen-containing contraceptives is inhibition of sperm penetration through the cervix into the upper genital tract (uterus and fallopian tubes) by decreasing the amount of and increasing the viscosity of the cervical mucus.

stuff that doesnt happen
Although endometrial effects have been hypothesized as a possible mechanism of action of combined hormonal contraceptives, insufficient evidence exists on whether cellular or biochemical changes in the endometrium could actually prevent implantation. However, the possibility of fertilization during COCP use is very small. Hence, endometrial changes are unlikely to play an important role, if any, in the observed effectiveness of COCPs.
how spermicide works
chance of still getting pregnant
- Perfect use -- 18%
- Typical use -- 29%
Quote
Spermicide is a substance that kills sperm, inserted vaginally prior to intercourse to prevent pregnancy.
oh... so you are really retarded and didnt understand that? ill explain it in terms you can understand.
Sean Taylor = sperm
end zone = egg
touchdown = egg becomes fertilized
The Pill
how it prevents Sean Taylor from scoring a touchdown:
- prevents the line painter from painting lines to make the end zone.
- turns the field into ice so that Sean Taylor slips and falls, never actually making it to the end zone
what it doesnt do:
- shoots Sean Taylor
- burns the end zone
- after making the touchdown it catapults Sean Taylor and the end zone turf out of the stadium
Spermicide
how it prevents Sean Taylor from scoring a touchdown:
"the wisdom of the wise will perish, the intelligence of the intelligent will vanish."
