The whole growing process : sperm-egg binding - implantation - normal-birth. In this process we must first sperm-egg binding. So is the task of sperm from the vagina and cervix into the mouth, into the fallopian tube through the uterine cavity. egg in the fallopian tube and eventually, when the fertilized egg cell divisions after the return womb implantation. This process required to build a high-quality sperm, it will be very difficult to complete this difficult to travel long distances. Most sperm has been all sorts of obstacles, and the phagocytic cells of adverse environmental impact of such factors. "The strong survive and the weak perish" in the selection process, which is extremely beneficial for gifted students. Only those who make the most healthiest sperm can "go through five passes, the slaying of the six" and arrived at the end of fertilization and egg. Sperm seen shoulder such a heavy responsibility, and also served on the road is so difficult.
To be able to pass through the sperm and oocyte eorona transparent, but not for eggs and egg. Operate when sperm in the female reproductive tract, through a series of patterns, such as the reproductive, and biochemical changes that can be agreed. After the sperm capacitation, greatly enhance its vitality. However, if the sperm in the female reproductive egg with a thousand miles away from what he really could not meet within 48 hours, and then began to be most sperm denaturation recession, and he eventually lost the ability to fertilization.
Directly affect the quality of sperm fertilization process, then many factors directly affect male sperm quality. If congenital normal physiological development, physical fitness, good or bad, whether eating habits law, sexual function Are there obstacles and so on.
Male sexual function including : sexuality, and to arouse sexual excitement, penile erection. copulate ejaculation and orgasm meet a series of sexual activities. Where one aspect of this anomaly, it is sexual dysfunction in men. Directly related to the male reproductive and sexual dysfunction, mainly impotence. Premature Ejaculation and abnormal ejaculation (including ejaculation and reverse ejaculation). Semen because they are unable to be transported to the normal female reproductive tract, which led to male infertility. In addition, abnormal sexual men (including sex and sexuality lower hyperthyroidism) can cause sterility. The former because of the number of sexual intercourse too little, can make sperm and egg meet ovulation period, the latter too frequent sexual intercourse frequency, The total number of sperm in each ejaculation so little, so that women are unable to conceive.
The criteria are : normal semen volume : 1.5-6 ml of semen liquefaction time : 5-45 minutes, pH 7-8. no obvious pool : viscosity, density : more than 20 million sperm / ml, total : more than 40 million sperm. Sperm : greater than 60% survival rate of activity : 3, the majority of sperm that was straight forward movement : more than 70% of normal sperm morphology, microstructure habitats : WBC less than 10 per high-power field.
Abnormal sperm is the result of many different diseases caused by various factors, men generally can be divided into : congenital abnormalities or genetic diseases caused by infertility, infection of genitourinary system caused by infertility. reproductive infertility caused by immune from secretory dysfunction induced infertility, Varicocele induced infertility. There are many external factors, such as the environment : pollution, the toxic side effects of some drugs, and all kinds of bad habits : drinking. trace elements, etc., may also lead to male infertility.
In view of the causes for targeted therapy, but in clinical practice. Some patients with abnormal sperm often find out the real reasons for these sexual idiopathic male infertility. only the experience of various treatment modalities for the treatment of choice in order to achieve the purpose of improving the quality of semen.
