- Pregnancy can happen the first time a guy and girl have sex, or if they are 'virgins'. Actually, more than half of all teenage pregnancies in Australia occur in the first 6 months of starting to have sex.
- You can get pregnant or give/get a sexually transmitted infection (STI) even if the withdrawal method is used - which is when the guy withdraws or 'pulls out in time' (before he ejaculates or cums).
- Sperm can hang around and stay alive in the vagina for 3-5 days after sex, so it's really hard to pick safe times.
How does pregnancy happen?
Getting pregnant is called conception. Around 14 days before a girl's period is due, her ovaries release an ovum (egg). This point of the menstrual cycle is called ovulation. Ovulation is the ideal time for a pregnancy to occur if a male and female have unprotected penis to vagina intercourse. During sex, when a male ejaculates (cums, reaches climax, orgasms) inside a female's vagina, about one teaspoon of semen - containing millions of sperm - is released into the vagina. The sperm swim into the womb and fallopian tubes. If just one sperm implants itself into the released egg, fertilisation occurs. If the fertilised egg implants in the wall of the womb, conception occurs and a new human life begins.
The above conditions are ideal for conception. But it is quite possible for a female to get pregnant even if:
- Sex occurs at another time in the menstrual cycle.
- The male has not ejaculated (this is because sperm is also present in the pre-cum, the clear fluid released from the penis prior to ejaculation).
- Any semen, including pre-cum, is deposited in or just outside the vagina.
- The female has not had an orgasm during intercourse.
