Successful fertility
Whether a couple can have children is indispensable.
First of all, whether sperm can enter the vagina, including whether there are two aspects of transportation ability and sperm.The former is commonly clinical is erectile dysfunction, genital malformations, non -ejaculation, and retrograde ejaculation. The latter can be divided into two types: non -obstruction and obstruction.At present, this part of patients can obtain "offspring" through surgery, drugs and husbands artificial insemination (AIH), and fine artificial insemination (AID).
Secondly, whether the sperm can reach the fallopian tube and the eggs.Clinically, men generally show that there are too few sperm or poor sperm activity. The treatment is generally mainly treated with Chinese and Western medicines.The most common woman is the fallopian tube obstruction or uninterrupted, which causes sperm to be unable to combine with eggs. The main treatment method is laparoscopic surgery or IVF.
Finally, whether sperm can get into the eggs to complete normal fertilization.The standards formulated by the World Health Organization is that the semen that men each time should be 2-6ml, and the sperm in each mL semen should be no less than 20 million.The sperm should be above 15%.Patients who fail to reach the standard have been treated with drugs after finding less causes; artificial insemination can also be artificially injected into the uterine cavity after washing in vitro, which has a high success rate.On the other hand, the fertilized process also requires the woman to provide good eggs, and sometimes it is necessary to perform "single sperm puncture in the egg cells", which is to use precision instruments under a microscope of 200-400 times.Inside the cytoplasm, put the well -developed embryo back to the uterus after fertilization.
