Conception to Birth
Conception
• In order to become pregnant an egg must be fertilised by sperm.
• When sperm is ejaculated from the penis it swims towards the cervix, through the fallopian tube until they meet an egg.
• The sperm then fertilises the egg (CONCEPTION)

Ovulation and Fertilization
• In the female, one of the ovaries produces an egg every 28 days. This is called ovulation.
• During sexual intercourse millions of sperm are ejaculated into the vagina.
• If a sperm meets the egg, the sperm’s nucleus can join with the egg’s nucleus.
• This fusing of the nuclei is called fertilization.
Conception
Length of Pregnancy
Pregnancy is divided in to three trimesters1-3 months 4-6 months7-9 months
Signs and SymptomsPregnancy – 40 weeksA missing menstrual periodMorning sickness and
nauseaFrequent urinationCravingsBreasts enlargeFatigue and dizziness
A simple urine test from the doctor will show whether or not a woman is pregnant.
Call the doctor if any of the following occur:
Vaginal bleedingSharp abdominal pain or crampingLoss of fluid from the vaginaSevere or prolonged nausea or vomitingFrequent dizzy spellsPainful urinationHigh fever over 100 degrees F.Vaginal discharge that is irritating
Other considerations:
No medications, including over-the counter drugs, unless approved by your doctor.
No drugs or alcohol.No x-rays.No saunas and hot tubs.No vaccinations during
pregnancy.Avoid cats, cattle, sheep and
pigs. They have a parasite that causes toxoplasmosis.
ZYGOTEA single sperm penetrates the
mother's egg cell, and the resulting cell is called a zygote.
Begins when egg is fertilized in the fallopian tube.
Ends 2 weeks later when the
zygote is implanted in the
wall of the uterus.The zygote contains all of the
genetic information (DNA) necessary to become a child.
Half of the genetic information comes from the mother’s egg and half from the father’s sperm
Upon implantation, complex connections between the mother and embryo develop to form the placenta.
The embryo may float freely in the uterus for about 48 hours before implanting.
EMBRYOThe cells of the embryo now multiply
and begin to take on specific functions. This process is called differentiation. It leads to the various cell types that make up a human being (such as blood cells, kidney cells, and nerve cells).
There is rapid growth, and the baby's main external features begin to take form. It is during this critical period (most of the first trimester) that the growing baby is most susceptible to damage.
From 3 to 8 weeks after
conception.
Body parts are formed during
this period.
By the end of the first month, the embryo is about 1/4 of an inch long.
The heart, no larger than a poppy seed, has begun beating
Head, mouth, liver, and intestines begin to take shape.
