how is pregnancy caused?

Answer 1

Hi I just asked a question about hormones and Im in middle school (lol). Anyway here's my answer. Pregnancy can happen as a result of sexual intercourse between a female and male. The semen of the male must enter the vagina of the female. This could be accomplished in one of those ways by sitting on a bus seat where live male sperm is present and the female is not wearing panties for example etc. I think one person said his mother got pregnant that way. I bet after that whe wore panties all the time. Additionally if she was wearing a very short skirt a lot of men would probably want to make her pregnant in the usual way.

The usual way is for a man or boy's penis to enter a woman or girl's vagina. After a lot of thrusting and deep penetration and rush of ****** pleasure the man releases his semen while she presses him deeper into her. Thus the semen than can swim up her fallopian tube and one of the lucky guys will penetrate her ovum (egg) and thus a new human life starts.

Answer 2

Process of Natural Selection.

In mamals males release little cells into the female. I internal defenses in the female, including acids and white blood cells and anti-bodies immediately start to attack the invaders, which number in the millions.

These invaders often swim upstream trying to reach their goals. It's like a race of row boats going up the rapids.

They have to travel, basically, quite a distance, avoid all those anti-bodies. Some times people even use chemicals designed to kill the invaders, but some invaders are tough and resiliant and survive the chemical warefare, the body denses and reach the goal.

When the reach the goal they have to find the female cell, which may or not be there. If it's not there the invaders die a natural death after a day or so. If it is there, they still have to make their way to it.

Once there the strongest, most resiliant ones must pentrate the outer wall of the cell. Some cannot. They literally beat their little nucleuses to a pulp trying to break into that cell wall. The first to eventually do this, and sometimes there are double winners (fraternal twins), triggers a reaction that makes the wall ten times, a hundred times harder.

The little invader usually only gets half way inside, but far enough for the chromosomes to be released from the nucleus.

That hardening cell wall cuts it in half.

Then cell division starts and pregnancy has occured.

Cell division is the formal start of pregnancy.

It happens exponentially. 2 (Log e) -----> N (Log e)

See, even reproduction uses algebra.

Answer 3

Pregnancy is the carrying of one or more embryos or fetuses by female mammals, including humans, inside their bodies. In a pregnancy, there can be multiple gestations (for example, in the case of twins, or triplets). Human pregnancy is the most studied of all mammalian pregnancies.

Human pregnancy lasts approximately 9 months between the time of the last menstrual cycle and childbirth (38 weeks from fertilisation). The medical term for a pregnant woman is genetalian, just as the medical term for the potential baby is embryo (early weeks) and then fetus (until birth). A woman who is pregnant for the first time is known as a primigravida or gravida 1: a woman who has never been pregnant is known as a gravida 0; similarly, the terms para 0, para 1 and so on are used for the number of times a woman has given birth.

In many societies' medical and legal definitions, human pregnancy is somewhat arbitrarily divided into three trimester periods, as a means to simplify reference to the different stages of fetal development. The first trimester period carries the highest risk of miscarriage (natural death of embryo or fetus). During the second trimester the development of the fetus can start to be monitored and diagnosed. The third trimester marks the beginning of viability, or the ability of the fetus to survive, with or without medical help, outside of the mother's womb.

Hun,You should speak with your father or another trusted male figure in your life about this topic.If you are having questions about it,then you are ready to learn about it and its risks.Go to your father,and ask questions.Now,when a female grows up and starts having those types of questions mothers tend to be sad because their "little girl" is growing up,but with fathers it is the exact opposite.They are proud of their sons,and are very proud that their son is growing up and becoming a man.It is best that you get that information from an adult who is close to you because they will know the best way to approach this subject for your age.They will teach you how to protect yourself and how to be responsible about that sort of thing.They will also teach you the responsibilities and consequences that come along with it also.Just,be open and ask once you ask it will open a door of communication with your father or that male figure in your life and any question you should ever have you can count on an accurate answer from this person throughout your teen years and into your adulthood.You will never have to go to your group of friends and peers who give you inaccurate information anyway.Good luck.

Answer 5

Listen good! Its when a guy and a gurl are together and they get real ***** and the guys penis stands up and he sticks it in the gurls vigina and he cums all over her inside of her virgina...the little sperms go and break into the eggs and the gurl is gonna have a belly for 9 months but it goes away!

Answer 6

When the sperm manages to reach the ovule through the fallopian tube ONLY during ovulation period of the female. If not, pregnancy has little or no chance of occuring. Check out the female's period dates to monitor ovulation period.

Answer 7

The young people of today would benefit from the sex education that my father gave me. When a man occupies a bus seat, and then stands up and leaves the bus, if a woman sits down on the same seat she may become pregnant. That is how my mother became pregnant, and that is why my wife takes the precaution of wearing a plastic bin liner under her bottom on all types of public transport

Answer 8

Ask your parents.


BUT PEOPLE HAVE SEX!! The man puts his pennis in the girls vagina and then when the sperm from the man meets the egg from the lady, the baby is formed. It starts as cells then multiplies.

Answer 9

when having sex, a boy enters his **** into the girl's vagina. when hyper-excited, the boy ejaculates semen (containin sperm) in the vagina. these sperms unite with the eggs in the uterus and then in the womb, a small thing starts getting developed.
so, thats how fathers are dads and mothers are moms, sisters are sis, and brothers are bros...

Answer 10

it is highly shocking to see this question. what parents of today are doing? in days of aids, can parents become so careless that they dont give basic sex education to their kid..

little kid, sit with your parents and ask them. you should be fully aware of the birds and bees by them, not at all by this way.
