Read: More and more couples know that if they want to get pregnant, they should schedule intercourse during their wife’s ovulation period. It is said that some couples preparing for pregnancy are tired of having intercourse with a stopwatch or having frequent sex during ovulation in order to get the sperm on the “knife edge”! In fact, this is not the right way to go. How should we arrange intercourse during pregnancy preparation? Ovulation is an instantaneous event, how do you know when the woman is ovulating? The female cycle, or menstrual cycle, is a month of about 28 to 30 days. Theoretically, a woman ovulates only once in a menstrual cycle and most women ovulate only one egg. For women with regular menstrual cycles of 28 to 30 days, ovulation will usually occur on the 14th to 16th day of the menstrual cycle; for women with less regular periods, ovulation will usually occur around the 14th day before the next menstrual flow. The day of ovulation can also be inferred by combining basal body temperature and cervical mucus observation. For example, when basal body temperature is measured, the day before the lowest temperature rise is the day of ovulation; the day when the cervical mucus is thin, clear and egg-white like, with the longest stretch is the day of ovulation; the LH test paper, which is currently popular in the market, is also convenient to use, and about 1 to 2 days after a strong positive is the day of ovulation. All of the above methods can be used to predict ovulation, which is easy to do, but there is no way to know how well the follicles are developing and whether they can be expelled. For couples with fertility problems, it is best to go to a fertility center for ultrasound monitoring of ovulation to clarify the development of follicles and the endometrium, so as to better grasp the ovulation date and facilitate natural conception. After knowing the ovulation date, how to arrange the time for intercourse? Theoretically, sperm can survive in the female reproductive tract for up to 72 hours. If you have intercourse 3 days before ovulation, you will be able to conceive. However, in practice, the duration of sperm survival in the female reproductive tract depends on the environment in the female reproductive tract. If the reproductive tract has poor pH and microorganisms, this may affect sperm viability and survival time, which in turn may affect the ability to fertilize. The egg does not live long, and the average survival time of an ovum after discharge is 12 to 24 hours, waiting for sperm to fertilize it. If the egg does not meet the sperm, or if it does, but is not fertilized, it will dissolve and be absorbed on its own. Therefore, from 3 days before to 1 day after the day of ovulation, it is a prime time to have intercourse. Patients often ask whether to have intercourse in the morning or in the evening? What time should I have intercourse? It is important to understand that ovulation cannot be accurately predicted and captured. Even ultrasound monitoring of ovulation every cycle cannot be done to a precise point in time, and since the movement of the egg in the reproductive tract is not known, it is pointless to dwell on this point in time. During the estimated ovulation period, it is important not to be punctual and to keep intercourse every other day. The actual fact that you should not be “saving your sperm” during the non-ovulatory period is also undesirable, because a long time without sex will make the sperm stay in the testicles for too long, which will easily make the sperm aging, vitality decline, but lead to a decrease in fertilization ability, not easy to conceive. So even during the non-ovulatory period, maintaining a sex life of one to two times a week is beneficial to the physiological and psychological health of both parties. In fact, a proper sex life is a normal need for all animals. This is God’s “brilliant design” for all species to reproduce, and this is also true for humans. When the dominant follicle is mature, before ovulation, the level of estrogen in the body rises, the cervical mucus becomes thinner, the amount increases, and the vaginal exudate increases, which helps intercourse and more sperm enter the uterine cavity, so it is conducive to conception. In ancient times and even in ancient times, how did people know when they were ovulating? When to have intercourse? If you maintain a regular sex life of 1 to 3 times a week during non-menstrual period, there will always be sperm that will meet the egg at the right time to meet the requirements of fertility. Ultrasound monitoring of ovulation For women with regular menstruation, if ultrasound monitoring has shown good follicle development, it is not necessary to monitor every month. For women with sporadic menstrual cycles, ovulation disorders or follicular dysplasia, ultrasound monitoring of ovulation is required after pharmacological ovulation treatment to understand the development of follicles and endometrium. On the day of follicle maturation, the doctor will give chorionic gonadotropin (hCG) injection to (1) promote follicle expulsion; (2) better control ovulation time, about 36-40 hours after hCG injection; and (3) enhance luteal function after ovulation. It is appropriate to start intercourse every other day on the night of hCG injection, 2 to 3 times. The two most important steps after ovulation are fertilization and implantation in order to conceive. The so-called implantation is a physiological process in which the embryo adheres to the endometrial epithelium and invades the endometrial stroma. Successful implantation requires a functioning embryo, a tolerable endometrium, and maternal-embryonic tissue interaction, the mechanisms of which are complex and the focus of current research. The human endometrium is only receptive to embryo implantation for a short, specific period of time during the luteal phase, called the implantation or implantation window. This is the period when the uterus is most receptive to embryo implantation, usually 7 to 10 days after ovulation. At this time, in addition to a certain thickness of the endometrium (7-8 mm), the uterus needs to be “nourished” by sex hormones, especially progesterone. A word of advice! A word of advice! Finally, it is very, very important that those who are preparing for pregnancy should improve their lifestyle and maintain a good mental state! If you are too nervous and stressed during intercourse, especially if the woman is impatient and complaining, it will lead to greater psychological pressure on the husband, and in serious cases, even sexual dysfunction, that is, “impotence”, which is a greater tragedy. In the ovulation period, the couple should avoid tension, and do not need to deliberately pursue the time, easy to conceive position and so on. Don’t worry about whether your follicles are round or flat, or whether your lining is thin or thick. You just need to let nature take its course, as the saying goes, “Do your best and follow the will of God”.
