The position of the uterus is divided into anterior, horizontal and posterior. If the uterus is facing the direction of the bladder, it is anterior, and if the uterus is facing the opposite direction, it is posterior, and a posterior uterus can have a certain effect on conception. If a posterior uterus wants to improve the conception rate, it is better to kneel behind during sex, while raising the hips or putting a pillow under the woman’s buttocks after sex, so that semen can accumulate in the posterior fornix of the uterus and thus the cervix can be immersed in semen, which will improve the conception rate. If the woman’s posterior position is more severe, a uterine support can be placed to provide a temporary corrective effect. If you want to increase the conception rate, it is best to have sex during ovulation, which is four days before and five days after the day of ovulation, and if you have intercourse during this period, your chances of getting pregnant will be greatly increased. Under normal menstruation, the day of ovulation is counted from the first day of the next menstrual period, and 14-16 days backward is the day of ovulation, or you can use ovulation test paper or follicle ultrasound monitoring to determine the date. During intercourse, do not be too nervous and relaxed, preferably in the morning when you are more energetic.
