Shortly afterwards, the placenta is also pushed out.
Implantation

The process of implantation stops the uterus lining from breaking down and causes the menstrual cycle to stop.
Pregnancy

Sexual Intercourse
Sexual intercourse occurs when the erect penis of the man is placed in the woman’s vagina.
Movement of the penis in the vagina causes semen containing sperm to be released from the penis.
Fertilisation
Fertilisation is when the nuclei of the egg and sperm cells fuse to form a fertilised egg known as a zygote.
Fertilisation occurs in the fallopian tube.
Family
Planning
Natural methods of contraception aim to detect the day on which ovulation takes place and then to avoid intercourse during the fertile period.
Artificial methods
Using a barrier (e.g. a condom) which can prevent fertilisation from taking place. It also stops the passing of diseases (STDs) from a Man’s Penis to the Vagina.
The contraceptive pill uses chemicals (hormones) to prevent ovulation.
