The five best positions for conception are not real and have no scientific basis. The process of conception is sexual intercourse, the male semen injection into the female vagina. The sperm swims to the uterus and into the fallopian tubes through the swinging of the flagellum at the end, and is generally not decisively related to posture, but the probability of conception increases with intercourse during ovulation. Under normal circumstances, a woman’s conception occurs at the time of ovulation. When menstruation is normal, ovulation occurs about 14 days before the next period. Intercourse during this period may increase the likelihood of pregnancy. The umbilical ends of the fallopian tubes of women of childbearing age catch the mature eggs discharged from the ovaries. Inside the fallopian tubes, the sperm and the egg combine to form a fertilized egg and move towards the uterine cavity as it develops due to the contraction and peristaltic movement of the tubes, and then complete the development of the embryo after it has been deposited in the uterine cavity. Before pregnancy need to go to the regular hospital for examination, men can check the quality of sperm, try to avoid the occurrence of fetal malformation.
