Many women are distressed by the difficulty of conception, and even into the misconceptions, when you get out of the following seven misconceptions you may find that conception is not so difficult as you phenomena, I hope that the following content will help you. 1, the use of lubricants during sex: many couples use lubricants during sex, but most of the lubricants bought in stores can damage sperm, is the real “forbidden fruit”. 2, non-ovulatory period to avoid sex: many couples believe that non-ovulatory sex will waste sperm, so store sperm until ovulation before having sex. In fact, the sperm stored for too long will be too tired and sluggish to be fertilized. In order to have a good chance of conception, sperm must be constantly updated to preserve freshness, which means that sperm should be ejaculated at least once every 5 days. 3. Overdose of vitamins: All kinds of vitamins are certainly necessary for conception and prevention of miscarriage. For example, if you take more than 1G of vitamin C per day, your cervical secretions will become dry and thick, which is not conducive to sperm penetration into the uterine cavity, thus reducing your chances of pregnancy. 4. Pressure to conceive: People are often under great pressure to conceive, and most doctors will tell you to relax. Most doctors will tell you to relax, but actually forcing yourself to “relax” is very difficult to do. Why not try “laughter therapy”, such as joining a humor club or watching some funny DVDs. 5, eat fish: fish is delicious, but it contains very high levels of mercury, which can affect the neurological development of the embryo. The mercury that enters the body can be stored for 2 weeks before it is gradually excreted, so when you are ready to conceive or within three months after conception should avoid eating fish, if you really want to eat fish, you can choose salmon with low mercury content. 6, rely on coffee: Although the specific mechanism of action is not very clear, but there are studies suggesting that a cup of coffee per day can reduce the pregnancy rate by more than 50%, three cups of coffee per day will reduce the pregnancy rate by 17.5%. If you want to conceive, it is best to stop drinking coffee to refresh your lifestyle. When you are ready to conceive you need to consult your doctor if the medication you have been using can be continued or if you need to replace it with other medication. For example, cimetidine, a drug used to treat peptic ulcers, can affect male fertility and should be discontinued when preparing for pregnancy.
