When it comes to the conditions for a woman to get pregnant, the most basic thing is that the reproductive system should be better prepared, in addition, in order to give birth to a healthy and intelligent baby, but also pay attention to the health of the mother-to-be p nutrition p emotional and environmental factors and so on. Only try to adjust all aspects of a relatively good state, in order to achieve “everything is ready, only waiting for fertilization”. So, what kind of physiological conditions women can get pregnant? (1) to have good quality raw materials – the normal discharge of the egg egg is the female reproductive cells. Women from puberty after the first menstruation, the ovaries began to play the function of ovulation, but at first not very regular, that is, not necessarily every menstrual cycle have ovulation, the quality of the discharged egg is not necessarily good. As the body grows and develops, the function of the hypothalamic-pituitary-ovarian axis is further improved and stabilized, and the function of ovulation becomes normal. As we know, women have two ovaries, one on each side of the uterus. Generally speaking, only one mature egg is released each month, and this is done alternately, with the left ovary ovulating one month and the right ovary ovulating the next. Occasionally, two eggs are ovulated at the same time, and this is the origin of the term “twins” such as “tornado”. Since normal ovulation is regular, when does it occur? Regardless of the length of the menstrual cycle, ovulation occurs approximately 14 days before the next menstrual period. For example, if you have a 30-day menstrual cycle, ovulation is likely to occur around day 16 of your menstrual cycle; if you have a 28-day menstrual cycle, ovulation will occur around day 14. However, nothing is absolute. Under the influence of certain factors, the ovaries may ovulate additionally, that is to say, ovulate another egg at a time other than the ovulation period, and if no contraception is used at this time, there is also a possibility of pregnancy. The egg can generally survive for 24 hours after discharge, during this period, if it can combine with the sperm to form a fertilized egg, it will be declared that the mother-to-be is pregnant; if the search but did not meet the sperm, it will be depressed, and thereafter, even if there is a “Romeo” rushed to the scene, but also can not be “Juliet” to produce a love child. “and Juliet will not be able to produce the fruit of love. (2) There is a weak sentry post – the thin cervical mucus – through which the cervical canal must pass in order to enter the uterine cavity and then the fallopian tubes as the sperm begins its slow journey from the vagina in search of the egg. The glands in the cervical canal produce cervical mucus, which is normally thick and sticky, and acts as a cork to seal the cervical canal, preventing sperm from passing through. During ovulation, however, the mucus becomes bright and thin, as if the barricade has been weakened, so that sperm can take advantage of the opportunity to get into the cervical mucus and swim to the uterine cavity. In addition, if there is cervical erosion or vaginitis and other inflammatory stimulation, cervical mucus is also easy to become sticky, not conducive to the passage of sperm. Therefore, thin cervical mucus is also one of the basic conditions for conception. (3) To have a normal operation of the conveyor belt – smooth fallopian tube The egg is discharged from the ovary to the pelvic cavity 8-10 minutes after the umbrella end of the fallopian tube will be like a finger to grasp the egg in, placed in the wider tubal potbelly. This is where the egg is waiting to be fertilized, or where the sperm is already waiting for the egg. The fallopian tube is also responsible for safely transporting the fertilized egg to the uterus, and if it fails to do so, resulting in an “ectopic pregnancy”, the embryo will die, or in some cases it will be amputated. Therefore, in order not to humiliate the mission, the fallopian tube should be kept from the umbrella end to the uterine cavity completely open, so that the egg, sperm and fertilized egg can pass through unimpeded; at the same time, it also has to have normal peristalsis to promote the advancement of the fertilized egg. And when the fallopian tube has inflammation or the neighbors in the pelvis are inflamed and spread to it, the fallopian tube will often be adhered or even blocked. Sperm and egg can not meet, the woman will not get pregnant, but in case there is a breakthrough “warrior” to find the egg, but also easy to have an ectopic pregnancy. (4) There should be fertile and safe soil – the endometrium during the secretion period. Little life settles in the uterus, just like a seed planted in the soil. Only a fertile soil can make the seed grow, so what kind of endometrium is considered nutritious? We already know that the lining of the uterus changes from a proliferative phase to a secretory phase, and the turning point is ovulation. After ovulation, the lining of the uterus undergoes a series of changes during the secretory phase and is ready to allow implantation of the embryo when it arrives and will continue to create a favorable environment for the development of the little one, providing it with high quality nutrients. If the lining of the uterus is inflamed or damaged, or if there is scarring from tuberculosis, the lining is like a hilly desert with poor soil, which is not conducive to the implantation of the embryo, and this may lead to miscarriage. In general, as long as the above conditions are met, and there are no other factors affecting conception (such as chromosomal, immune, endocrine and other diseases), the mother-to-be is ready to get pregnant.
