In order to improve the “hit rate” of conception, it is necessary to first understand the basic conditions that must be met in order to conceive. Conception is a complex physiological process. The following conditions must be present: the ovaries must produce normal eggs, the semen must contain normally moving sperm, the egg and sperm must meet in the fallopian tube and be transported into the uterine cavity as a pregnant egg, and the endometrium must be suitable for the egg to settle. Just one of these conditions can prevent conception and lead to infertility if one of them is not normal. The second thing is to grasp the best time to conceive, as the timing of conception is prescriptive. Therefore, the best time to conceive is to arrange sex by accurately grasping the ovulation date. Self-determination of ovulation date With the use of ultrasound or laparoscopy, the doctor can directly observe how the ovaries slowly expel a mature egg. In the vast majority of cases, a woman cannot observe this on her own, but can only know from the arrival of her next period that she has ovulated once more this month. However, with some simple knowledge, women can tell if and when they are ovulating. Basal body temperature The temperature of a normal woman taken immediately after waking up after a full night’s sleep is called the basal body temperature, and is usually taken early in the morning before she wakes up. During the period before ovulation day, the basal body temperature is usually below 36.5℃, and then drops a little bit until the day before ovulation day, when the body temperature is the lowest. Each woman can calculate her ovulation day from the lowest day according to this regular basal body temperature. Cervical mucus method Many human organs (cavernous organs) have a wonderful ability to open and close themselves, and so does the uterus. On the surface, it appears that the cervix is connected to the vagina and is unobstructed. But this is not the case. During menstruation, it allows menstruation to pass, and in the second half of the menstrual cycle, the mucus secreted by the uterus is sticky and thick, forming a “plug” that blocks the opening of the cervix, when even the most powerful sperm cannot pass through this “barrier”. The sperm can easily pass through the cervix and enter the uterus. 24 hours later, the cervix closes again on its own. Therefore, you can tell if you are ovulating by observing the state of the mucus in your cervix, which is like a clear nasal discharge. The intermenstrual pain sensation method The human egg matures from one ovary once a month, “squeezes” out of the ovary and is released to swim to the fallopian tube. This is a kinetic process. This process of leaving the ovary takes about 1 to 2 minutes. At this point, the follicle ruptures and the egg emerges, causing a slight bleeding. If this bleeding is right against the peritoneum, it can produce an uncomfortable sensation, a vague pain, called intermenstrual pain. Some women do not feel pain, but only a soreness in one side of the lower back, while others feel a swelling in the lower back, and some women do not even experience any discomfort. Women who experience this sensation can predict their ovulation day and arrange the time of conception by paying attention to their sensations around the estimated ovulation period based on their past experience. Calendar method Women who have regular menstruation can use their calendar cards to predict their ovulation date. Generally speaking, the day of ovulation falls on the 14th day before the next menstrual period. If you mark this date on your calendar card and arrange your sex life accordingly, you will be most likely to conceive. Points to note on self-testing the ovulation date: These methods of determining the ovulation date by self-perception without instruments are simple, but they must be used skillfully and correctly to be effective. It is recommended that women who use this method pay attention to the following points: 1. It is best to use several methods in combination to improve accuracy. 2. It is difficult for women with irregular menstruation to measure accurately by self determination. 3. It is not easy to measure accurately when there are endocrine disorders, chronic and long-term use of certain drugs and other conditions that interfere. 4.When there are really other organic causes of infertility
