Egg cells discharged from the ovary, into the fallopian tube; sperm in the process of passing through the cervix, the uterine cavity, by the influence of a variety of factors most of the deaths, of which only the strongest sperm cells, with the help of uterine contractions and peristalsis of the fallopian tubes, to reach the tubal jugular abdomen, into the egg cells, to complete the fertilization, that is, the sperm cells and the egg cells to reach the combination of “fertilized eggs “Fertilization is accomplished. The fertilized egg undergoes cell division, gradually moves towards the uterus, and finally stops at the endometrium, which is medically called “implantation”, and absorbs nutrients from the mother’s body through the placenta, and continues to develop into a hanging embryo until the human body is formed. The smooth progress of this process depends on good quality eggs and strong sperm. The Reproductive Center at Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University, carries out routine tests such as sperm viability, concentration and sperm morphology analysis, seminal plasma biochemical analysis, sperm acrosomal enzyme activity analysis, sperm DNA fragmentation analysis, sperm hyaluronic acid assay and other sperm function tests, and is able to provide a comprehensive assessment of male fertility and offer a wide range of solutions for different patients.
