HOW ARE BABIES MADE
Motherhood
is a blessing and a woman is complete after she is
a mother. In order to conceive it is important that
you know exactly what your body will be going through
and how you will conceive and deliver your baby. In
this article we will try to explain the whole procedure
of conceiving and producing a baby.
Inside the woman's body
Women have two kiwi-shaped balls known as ovaries
attached to either side of your uterus which are full
of eggs. Every infant girl is born with more than
500,000 eggs (more than a lifetime's supply) in her
ovaries. Most of these eggs begin dying off almost
immediately but you are still justify with plenty
for your reproductive years. Altogether you'll probably
release about 400 eggs, beginning with your first
period and ending when menopause arrives, usually
between ages 45 and 55. Sometime during the middle
of your menstrual cycle (most likely between the 12th
and 16th days), an egg reaches maturity in one of
the two ovaries, which releases it into the abdomen,
where it's quickly sucked up by the tulip-shaped opening
of the nearest Fallopian tube; these are two 4-inch
canals leading from the ovaries to the uterus. This
release, known as ovulation, starts the conception
clock ticking. The average egg lives only 24 hours,
so it has to be fertilized soon if a baby is to be
conceived. If your egg meets up with a healthy sperm
on its way to the uterus, the two can join and begin
the process of creating a new life. If not, it ends
its journey at the uterus, where it disintegrates
and is expelled a couple of weeks later during your
period.
Inside
the man's body
While women are busy maturing a single egg at the
leisurely pace of about one a month, men are almost
constantly at work producing millions of microscopic
sperm, whose sole purpose in life is to swim for their
lives and penetrate an egg. While women come complete
with all the eggs they'll ever need, men aren't born
with ready-made sperm. They have to make them on a
regular basis - from start to finish it takes about
64 to 72 days to create a new sperm cell. With every
ejaculation a man releases around 200 to 350 million
sperms and an average sperm lives only a few weeks
in a man's body. Sperm production starts in the testicles,
the two glands housed in the scrotal sac beneath the
penis. The testicles hang outside the body because
they're quite sensitive to temperature. To produce
healthy sperm they have to stay at 94 degrees Fahrenheit
- about four degrees cooler than normal body temperature.
Once the sperm is created, it's stored in a portion
of the testicle known as the epididymis until it's
scooped up and mixed with semen just prior to ejaculation.
Despite
the millions of sperm that are produced and released
in each ejaculate, only one can fertilize an egg (this
is the case even for twins). The gender of the resulting
embryo depends on which type of sperm burrows into
the egg first - sperm with a Y chromosome will make
a boy baby, and sperm with an X chromosome will make
a girl.
What happens while you're
having sex
While making love your bodies build up tension that
results in orgasm. In men, orgasm propels rich semen
into the vagina and up against the cervix at roughly
10 miles per hour. This process, known as ejaculation,
gives sperm a head start on their way to the egg.
A woman's climax also aids conception. Some research
shows that the wavelike contractions associated with
the female O help pull the sperm farther into the
cervix. Certain positions like the missionary position
(man on top) or the rear-entry position (man behind
woman, both facing the same direction) are best because
they allow for deep penetration. It is also very important
to keep tract of your ovulation period if you are
planning to get pregnant. That means you should aim
to make love at least every other day during the middle
of your cycle.
The
Final Destination
If conception is going to happen, it will be in the
first few hours after sex. It is advisable for the
woman to stay on her back with a pillow under her
bottom for at least 20 or 30 minutes so gravity can
help the sperm get to the waiting egg. What is happening
inside your body is that those millions of sperm have
begun their quest to find your egg, and an easy journey
it's not. The first obstacle is the acid level in
your vagina, which can be deadly to sperm. Then there's
your cervical mucus, which can seem like an impenetrable
net except on the one or two days when you're most
fertile and it miraculously loosens up so a few of
the strongest swimmers can get through. But that's
not all; the sperm that survive still have a long
road ahead. In all they need to travel about seven
inches from the cervix through the uterus to the Fallopian
tubes. When you consider that they travel at a rate
of roughly an inch every 15 minutes, that's quite
a trip. The fastest swimmers may find the egg in as
little as 45 minutes, while the slowest can take up
to 12 hours. If they don't find an egg in the Fallopian
tubes at the time of intercourse, the sperm can wait
there in a resting stage for up to 72 hours.
The
attrition rate for sperm is so high that only a few
dozen ever make it to the egg. The rest get trapped,
lost - perhaps heading up the wrong Fallopian tube
- or die along the way. For the lucky few who get
near the egg, the race isn't over. They have to work
frantically to penetrate the egg's outer shell and
get inside before the others. When the hardiest of
the bunch makes it through, the egg changes instantaneously
so that no other sperm can get in. It's like a protective
shield that clamps down over the egg at the exact
moment that first sperm is safely inside.
Now
the real miracle begins. The egg will be fertilized
within about 24 hours as the genetic material from
the sperm combines with the genetic material in the
egg to create a new cell that will rapidly start dividing.
You're not actually pregnant until that bundle of
new cells, known as the embryo, travels the rest of
the way down the Fallopian tube and attaches itself
to the wall of your uterus. (Although you can have
an ectopic pregnancy if the embryo implants somewhere
other than the uterus, usually in the Fallopian tube.
An ectopic pregnancy is not viable, and the embryo
has to be surgically removed to prevent rupture and
damage to the Fallopian tube.) That final leg of the
trip can take another three days or so, but it may
be a few more weeks until you miss a period and suspect
that you're going to have a baby.
Once
you have missed your period - or noticed one of the
other signs of pregnancy - you can use verify to confirm
whether you are pregnant or not.
