Fertilization and Pregnancy

If a man and woman make love without using contraception at the time when a woman is about to occur during ovulation, it is very likely that intercourse will result in pregnancy.

When a man's penis is in the vagina, and he had ejaculation, the sperm in this case is at the far end of the vagina.If the sperm fertilize the recently release an egg in the fallopian tube, then it is a long and dangerous journey.The reproductive system of men and women is arranged so that the egg and the sperm have met anyway.Before ovulation clitoris produces a "life-giving" musk, which helps to ensure that the sperm found their way to the right place.This musk contains proteins and sugars that are fed sperm along the way.In order for the sperm was able to connect with the egg, it is necessary to swim a distance of 15 cm. This is truly a marathon swim, and, taking into account the size of the microscopic sperm, it can be assumed that it does so extremely rapidly.Every hour he swims 2.5 cm!At the same time it helps the rhythmi

c muscular contractions of the uterus and fallopian tubes.Fertilization occurs approximately during the next 10-12 hours after intercourse.However, there are cases where particularly nimble sperm were doing this way in just 30 minutes.Sperm cells remain viable for a further 7 days, but their reproductive ability

they lose three days later.It turns out that sperm are trapped in a woman's body before ovulation, remain viable for 3 more days and waiting for the female reproductive system will release a new egg cell ready for fertilization.

Sperm accumulate in the fallopian tube around the egg, which is to be released, then one of the sperm cells can break through the shell of the egg, then fertilization occurs.Male and female germ cells are merged into one.This egg is called diploid.Diploid oocyte is in constant motion.She is constantly divided and divided until it forms the embryo.It embryo comes down the fallopian tube, and then attached to the inside of the mucosal lining of the uterus.So there is a process that is called "implanting".His journey originated embryo is doing for 5 - 7 days.When the embryo is fully implanted, the process of conception is considered complete.

embryo is implanted in the uterus starts to produce HCG, which enters the bloodstream.It is this hormone present in the urine of a woman when she makes a pregnancy test.At

blood flow HCG nestles in the ovaries, which promotes the formation of the corpus luteum, iewhat becomes a sack, freed from the egg.The corpus luteum meanwhile continues to produce progesterone, which strengthens the walls of the uterus, thus creating favorable conditions for the passage of pregnancy.

Even if the sperm got into the woman's body, it does not mean that fertilization must necessarily happen.This is because, firstly, not every the released egg is fertilized.Secondly, because of the fertilized eggs may not always be implanted.Such egg subsequently rejected by the body after implantation.Therefore, a healthy couple during intercourse that takes place without the use of contraceptives, on average it takes about 24 months to produce a conception.However, this does not mean that a young man and a woman can not be from once to achieve the same result.Statistical data from different countries talking about a large number of unplanned pregnancies.
