What is the process of conception
Conception - a complex physiological process, during which a woman's egg is fertilized by the sperm of men.The woman in each ovary contains about 200,000 immature eggs.By the time puberty full development and maturation of oocytes reach 400-500.
possibility of having children a woman is dependent on the menstrual cycle, during which under the influence of hormones going on oocyte maturation in the ovary and its access to the fallopian tube or peritoneal cavity to fertilize.The process of entering the mature egg from the ovary is called ovulation.In women ovulate each month for a certain period of time, which is called childbearing or fertile period.This period begins with the appearance of the first menstruation (menarche) in 11-16 years and ends with the last menstruation, in 48-55 years, after which menopause.
During ovulation, the egg is released from the ovary and into the abdominal cavity, where captured the funnel of the fallopian tube.In the fallopian tube meets the egg with the sperm.The fertilization is involved only one sperm nucleus is fused with the nucleus of the egg.From this moment begins a pregnancy.
fertilized egg divides and at the same time moving the fallopian tube, it is promoted by its peristaltic movements and movements of ciliated epithelium of the mucous membrane.At 7-8 day from the moment of conception, the egg gets to the uterus, which is embedded in the mucous membrane that contains all the necessary nutrients for the development of the embryo.The mucous membrane of the uterus is prepared to receive the embryo: under the influence of female hormones and pituitary hormones, it expands and becomes more friable - in a more easily penetrate the mucous membrane of the embryo.
most favorable time for fertilization and pregnancy is considered to be the middle of the menstrual cycle - the period of ovulation and one day after.Suitable for a ovulation and several days before ovulation Ovulation - How to determine as accurately as possible? , despite the fact that during this period the body yet ripe, ready to fertilize the egg.The fact that the sperm can maintain their livelihoods for about five days and then fertilize the mature egg.
Statistically, healthy couples who have sex 2-3 times a week without contraception, to conceive Conception, ovarian cycle, fertilization and genetics baby usually requires six months to a year, so do not panicIf pregnancy does not come at once.There are many moments of importance: the stresses associated with the wedding, a change of lifestyle, the recent use of hormonal birth control pills Hormonal birth control pills - a modern method of preventing preg (after receiving the hormones may be reduced in the period from one month to six months)and so on.
What can prevent conception
If you could not conceive a child for a year, then it is cause for seeking medical attention and complete examination.During the examination, the woman checked hormones, carried ultrasound genitals, laboratory tests to rule out infection and inflammation.Inspect and man: he also identify various infections, hormones checked and examined for the presence of semen and sperm viability.
may prevent conception:
- changes in the menstrual cycle, which are accompanied by violation of oocyte maturation;Today there exist various methods restore normal menstrual cycle using hormones;
- inflammation of the female genital organs, which can lead to obstruction of the fallopian tubes fallopian tubes - asymptomatic ;it also surmountable obstacle often after treatment tube patency is restored;if this is not possible, there is a method of in vitro fertilization (IVF), when a woman takes the egg from the ovary, fertilized in vitro with sperm of her husband, aged in certain circumstances, in special incubators, and then implanted into the uterus of the woman;
- gross changes in the structure of female genital mutilation, which do not allow to bear a child;It's tough, but also surmountable obstacle: the aid may come a surrogate mother;
- infertility husband;There are methods of increasing sperm fertilizing properties (if there are live sperm, but they are few and they are not viable);If a man is completely sterile, it is possible to use donor sperm.
Today, there is no reason to despair, if it is impossible to conceive naturally.Of course, all medical techniques require patience and work on them, but in most cases they give a positive result.
