There is no scientific basis for the statement that the best time to conceive is between 10 p.m. and 2 p.m. As long as there is ovulation, conception can take place, and there is no time limit. For women with regular menstrual cycles, ovulation usually occurs around the 14th day before the next menstrual period, and sperm can usually survive for 1-3 days after entering the female reproductive tract, so the 3-4 days before and after ovulation are easy time for conception. Fertilization occurs in most cases within a few hours after ovulation, usually no more than 24 hours. It is not possible to pinpoint the exact time of conception, nor is there an optimal time period for conception. The process of the sperm and secondary oocyte meeting in the fallopian tube to form a fertilized egg can occur at any time of the day. The health of the sperm and egg, and the uterine environment are closely related to the smooth and healthy growth of the embryo, so do not believe in prescriptions and statements that have no scientific basis.
