As a rule, a successful pregnancy requires adequate preparation, knowledge of the right methods and techniques, and knowledge of pregnancy-related expertise, which will yield twice the result with half the effort. The first step is to know when to ovulate and choose the best time for the sperm and egg to unite. For women with regular menstrual periods, you can calculate the ovulation period yourself, which is usually around 14 days before the next menstrual period. For women with irregular periods, you can use ovulation test paper combined with ultrasound to detect ovulation. If there is a need for fertility, the chances of pregnancy can be increased by keeping intercourse once every two days starting from the first day of ovulation and keeping the woman’s buttocks elevated with a pillow for about one hour after intercourse. Secondly, it is important to have a good preconception checkup, especially for those who are of advanced maternal age or have a history of genetic diseases. Men need to ensure that they have healthy, strong and sufficient number of sperm, thus improving the chances of egg fertilization. The woman should ensure that she has healthy eggs that can be discharged properly before preparing for pregnancy. In terms of diet, both spouses should ensure a balanced diet and adequate nutritional intake. Men should eat more zinc-rich foods, such as fine meat, chicken and seafood. Also, stop smoking and drinking, take rest and keep your mood happy.
