The frequency of intercourse during pregnancy preparation is a problem for many couples preparing for pregnancy, but it is difficult to talk about this issue and they are always embarrassed to ask people about it. If the frequency of intercourse during pregnancy preparation is high, husbands tend to be less energetic and it is difficult to ensure the quality of sperm; if the frequency of intercourse is too low, they are afraid of missing the ovulation period – we should know that both sperm and eggs have their own survival time and the waiting time for meeting is not long, so if the best time for conception is missed, then we have to wait for another cycle. If you miss the best time to conceive, you will have to wait for another cycle. Many sisters ask, “If this is the case, what is the scientific way to schedule intercourse for pregnancy preparation? How often should we have intercourse during pregnancy preparation? There is no universally accepted standard for the frequency of intercourse during pregnancy preparation. There is no universally accepted standard for the frequency of intercourse. However, American sexologists announced a sex formula in a sexology forum organized in China: “Frequency of sex = first digit of age x 9”. According to this formula, a person in the twenty age group (20 to 29 years old), his (her) sex formula is 2 × 9 = 18, 18 can be seen as a combination of 10 and 8, that is, the frequency of sex suitable for him (her) is 8 times in 10 days; a person in the thirty age group (30 to 39 years old), his (her) sex formula is 3 × 9 = 27, that is, he (she) is suitable to have sex 7 times in 20 days. Does the frequency of your intercourse meet this formula? My guess is that most people do not conform. In fact, in the 20-29 age group, if 8 times in 10 days, in fact, is considered more exaggerated. To put it another way, in the thirty age group of 30, and in the twenty age group of 29, the age difference is not much, but the frequency is very different, obviously is not reasonable. Besides, if the wife is in the twenty age group and the husband is in the thirty age group, who prevails? Suppose the wife is 28 years old, the husband is 32 years old, then the wife 10 days to have sex 8 times, the husband 20 days to have sex 7 times, the wife is not very embarrassed? Is this to make people cheat? The same room during pregnancy preparation: to have moderation, according to the ability from the above we can know that the frequency of sex follows the formula is unquestionable. It is definitely not a good idea to have intercourse every day in order to get pregnant. According to the traditional Chinese theory, when having intercourse, a person loses sperm and blood. A person’s sperm blood is limited and needs to be maintained. Therefore, couples need to abstain from sexual intercourse, so many husbands also need to nurture the “essence” to store up. Of course, not too much restraint, if too much attention to the “sperm” is not desirable, because on the other hand, the number of intercourse is not conducive to conception. If the number of intercourse is too low, the sperm will stay in the testicles for too long, which will make it easy for the sperm to age, thus decreasing the vitality and resulting in a low quality fertilized egg, which will not easily produce a healthy and smart child. So generally speaking, 1-2 times a week is about right during the non-ovulation period, and a little more frequently during the ovulation period, depending on the situation. Therefore, it is still very important to measure ovulation. The frequency of intercourse during ovulation is recommended: once every 2 days during ovulation. After the egg is discharged, it can only survive for 12 to 24 hours, and sperm can only live for 1 to 3 days in the female reproductive tract, so generally speaking, it is most likely to conceive from 3 days before ovulation to 1 day after ovulation. If the sperm start early, that is, 1 week before ovulation, have intercourse every 2 days, this can ensure the quality of the sperm to reach the fallopian tube early, or on time, and meet with the egg to form a fertilized egg. Therefore, the best time to have intercourse during ovulation is once every other day after the start of ovulation to ensure the quality of sperm and to maximize the chance of conception, and after intercourse, it is best for women to lie on their backs for a while to promote conception. When should I have intercourse during ovulation? Many “experienced” people say that it is easier to conceive when the ovulation test is strong and weak. “The best time to conceive in the eyes of many people is therefore the time when the ovulation test is strong and weak. Many sisters do not know what is going on when the ovulation test paper becomes weak. If the ovulation test paper is used in the right way, you can predict ovulation by looking at the ovulation test paper and have intercourse as early as possible when you find that the ovulation test paper becomes strong and weak. There are many factors that affect the basal body temperature, so when you find that the basal body temperature has risen and you have already ovulated, it may be too late to have intercourse. If you find that the ovulation test has changed from strong to weak, you need to combine it with the basal body temperature, which rises after the ovulation test has changed to weak. Theoretically, sperm can survive in the female reproductive tract for up to 72 hours, so it is theoretically possible to conceive if you have intercourse 2 days before ovulation, but in reality, the survival time of sperm in the female reproductive tract depends on the environment of the female reproductive tract, if there is cervicitis, vaginitis, etc., it may affect the vitality and survival time of sperm, which in turn affects the ability to fertilize. That is why many people also recommend intercourse after the ovulation test turns weak. Therefore, theoretically, it seems to be more likely to conceive when the ovulation test is strong and weak. However, I don’t agree with the idea of having intercourse to a certain minute or second at a certain time, as long as it is during ovulation and you feel it, you should have intercourse without worrying too much. In general, there are several reasons for infertility during ovulation: 1. Fallopian tube factor: Fallopian tube obstruction has always been the main cause of female infertility. When the fallopian tube is inflamed, the mucosal secretion is reduced, the lumen is adhered, and the entire peristalsis of the fallopian tube is weakened, which can not only lead to infertility, but also induce ectopic pregnancy. When suffering from pelvic endometriosis, it can also cause the fallopian tubes to adhere and distort and cause infertility. 2. Vulvar and vaginal factors: deformities such as imperforate hymen, transverse vaginal septum and congenital absence of vagina can prevent sexual intercourse; or in case of severe vaginitis, a large number of pathogenic microorganisms and white blood cells can engulf sperm and lead to infertility. 3, ovarian factors: congenital absence of ovaries, infantile ovaries, polycystic ovaries or premature ovarian failure, ovarian inflammation, etc., can affect ovarian ovulation and infertility. 4, uterine factors: the normal position of the uterus is forward leaning and forward flexing, the cervical opening backwards, after sexual intercourse ejaculation cervical opening immersed in the pool of semen and conducive to conception. If the uterus is posteriorly inclined and retroflexed, the cervical opening is upward, which can affect the entry of sperm into the uterine cavity and lead to infertility, and endometritis hinders the implantation of pregnant eggs. 5, cervical factors: the cervical opening during ovulation is 1 mm in diameter after menstruation to 3 mm, and the cervical mucus is clear and transparent with a pH value of 7.0-8.2, which neutralizes the acidity of the vagina and facilitates the passage of sperm. In case of chronic cervicitis or low estrogen level, the cervical mucus can contain a large number of white blood cells or be sticky in texture and affect conception. If you are suffering from cervical polyps, you can block the passage of sperm. 6, immune factors: there are a few couples, the examination of both sides did not find obvious causes of infertility, but by the infertility caused by anti-sperm antibodies in the serum of infertile women. 7, mentality is also very important: in the ovulation period together, do not be too nervous, relax, let nature take its course, do not be too deliberate to pursue the online said easy to conceive position and so on, in short, how easy casual how to come.
