A small embryo carries the sorrow and joy of many infertile families, and a good quality embryo can greatly increase the hit rate of pregnancy! However, the quality of embryos obtained during IVF is not the same for everyone. There are three major factors that affect the quality of embryos: the age of the couple, the quality of the sperm and eggs, and the laboratory incubation technique. We all know that we should have children while we are young, but the high pressure society nowadays makes many young couples afraid to have children without a stable financial base. But as we grow older our fertility declines or various factors cause infertility having to take the shortcut of IVF. In fact, the success rate of IVF is also related to the age of the couple, the older the couple, the lower the success rate, mainly because the fertility of older people is declining sperm and egg quality is not as good as the best period of fertility in the twenties. A good quality egg and sperm will form a beautiful embryo after fertilization and the baby will be relatively healthier. In addition to the age factor causing poor quality eggs in women or sperm in men, there are many other factors that can cause a young couple to have poor quality sperm or eggs! For women, such as ovarian chocolate cysts, premature ovarian failure, egg abnormalities, etc., can all contribute to poor egg quality. In men, stressful work, smoking and drinking, poor lifestyle or genetics can all contribute to poor sperm quality in young men. Once the fertility of one of the partners deteriorates, it will definitely affect the quality of the embryos produced. Another key factor in hatching good quality embryos is a high quality fertility center. The skill, experience, equipment and culture fluid of the technicians who hatch the embryos in the laboratory are all critical. Choosing a fertility center with high quality technology can help you get twice the result with half the effort. Unfortunately, choosing a fertility center with mediocre technology and equipment will definitely affect the quality of your final embryos!
