From a biological perspective, the conception process is a complex and finely regulated natural phenomenon. The female reproductive system follows a cyclic pattern, called the menstrual cycle, which usually lasts around 28 days, but the length of this cycle can vary between women and fluctuate with age and physiological conditions.
One of the most critical events in the menstrual cycle is ovulation, the release of a mature egg from the ovary. Ovulation usually occurs about 14 days before the next menstrual period. This time is called the ovulation period. The ovulation period is the most fertile period for women, because the egg is in a fertilizable state at this time, and the survival time of sperm in the female reproductive tract is about 3-5 days, so having sexual intercourse within a few days before and after ovulation has a higher risk chances of conception.
Under normal circumstances, women of childbearing age ovulate once a month. After the egg is released from the ovary, it has the ability to be fertilized for only 24 hours, so it is necessary to grasp the ovulation period. If your menstrual cycle lasts 28 days, ovulation will occur in the middle of your period. If the menstrual cycle is one week early or late, ovulation will occur around the 14th day before the next menstrual period. In the pre-ovulatory period, a woman\’s basal body temperature is low, about 36.4 to 36.6. After ovulation, body temperature will rise by about 0.3 to 0.5 until it drops before menstruation. Therefore, measuring basal body temperature helps to understand the ovulation period. Having sex around the time of ovulation (including the time of ovulation and the day or two before and after) can increase your chances of getting pregnant. 
Some people are wrong It is believed that frequent or infrequent sexual intercourse can increase the chance of pregnancy. There is a \”moderate\” for everything. Women with regular menstruation can calculate it according to the above method. Women with irregular menstruation are best to check their basal body temperature for more than 3 months to find out their ovulation period. They can also use LH test strips to detect when ovulation occurs.
Throughout the ages, many people have believed that a woman can become pregnant only if both men and women reach orgasm at the same time during sexual intercourse. There is a right side to this too. Ancient Fangzhongshu emphasizes that \”sex comes before sex\”. Men and women \”enjoy love together.\” For example, \”Minutes of Guangsi\” says: \”When a man and a woman are moved by their feelings, have a spiritual connection, and then put them into action, yin and yang will be harmonious, and the essence and blood will be condensed. This is the way to give birth to a child.\”
In modern times, some scholars have proposed that human intelligence, physical strength, and emotions are both independent and unified. If the three are balanced, the body will be in optimal condition. When the cells in the body are active, the metabolism is strong, the thinking is quick, the mood is high, and the spirit is high, men and womenWhen orgasms occur simultaneously, the child born will be bright and smart. If a couple is unable to conceive, is inseparable, and has strange dreams in the same bed, ovulation is often suppressed. But it is undeniable that pregnancies such as rape, humiliation, struggle to escape, and \”artificial insemination\” do not occur consciously by both parties.
Therefore, in order to grasp the timing of conception, in addition to the man\’s normal fertility, the key is whether the woman has normal ovulation. Ancient physicians had observed this. For example, \”Guidelines for Treatment·Qiuzi·Knowing Time\” means \”there is one day at the end of a month, and there is an hour at the end of a day.\” Every woman will have a menstruation, and there will also be a day of marriage… If given at this time, the pregnancy will be completed. It is clearly pointed out that during the \”in-law period\”, which is what Western medicine calls the \”ovulation period\”, sexual intercourse can lead to pregnancy.
