Egg to embryo
From a tiny egg to a growing embryo take a look how conception takes place.
Each month a female releases an egg from one of her two ovaries. This is called ovulation
The egg travels into the fallopian tube where it awaits sperm
to fertilise it.
An average ejaculate discharges 40-150 million sperm which swim towards the fallopian tube, but only a few hundred will come close to the egg.
Once the sperm penetrates the egg the fertilisation process takes about 24 hours to happen.
The fertilised egg divides and grows into many cells. It then leaves the fallopian tube and enters the uterus.
Within a week pregnancy hormones
are present in the blood, but will take three to four weeks to be detected by home pregnancy tests.
At week five the baby’s heart begins to beat and the brain, spinal cord and other organs also start to form.
