How can IVF sperm increase survival rate?
The development of IVF technology has enabled many infertile couples to realize their dream of becoming parents. The success of IVF is closely related to the survival rate of sperm. Therefore, improving the survival rate of sperm is the key to the success of IVF. How to increase the survival rate of IVF sperm is described in detail from four aspects below.
Environmental conditions for maintaining sperm vitality
In order to improve the survival rate of sperm, the vitality of sperm should be maintained first. In the IVF laboratory, environmental conditions are a very important factor. IVF hospitals usually control the temperature, humidity and air quality of the laboratory to create the most appropriate environmental conditions. In addition, laboratory personnel will follow strict operating procedures, including the use of aseptic technology, correct culture medium and storage conditions, to ensure the health and survival of sperm.
In addition, the transportation and storage of semen samples are also important links that affect sperm survival rate. Some advanced hospitals provide professional sperm freezing and storage services to ensure that sperm will not be damaged during transportation. These protective measures can improve the survival rate of sperm and provide high-quality sperm samples for IVF surgery.
Sperm processing and purification technology
Sperm processing and purification technology is an indispensable part of IVF surgery. The traditional sperm treatment methods include centrifugation, washing and dilution, aiming to remove harmful substances carried by sperm and improve its vitality and quality. These steps help to screen healthy and active sperm, so as to increase the survival rate of sperm in the process of in vitro fertilization.
In recent years, some new sperm purification technologies have also been introduced into IVF surgery. For example, ion separation, magnetic field separation and flow cytometry can further improve the purity and quality of sperm, thus improving its survival rate. These advanced technologies are more accurate in selecting sperm, which will help to improve the success rate of IVF.
Using assisted reproductive technology to improve sperm survival rate
In addition to traditional sperm processing methods, there are some assisted reproductive technologies that can improve the survival rate of sperm. These include single sperm injection (ICSI) and acrosome reaction.
Single sperm injection technology can directly inject a healthy and active sperm into the egg to improve the success rate of fertilization. This method is applicable to those couples with less sperm or poor sperm quality, which can greatly improve the success rate of IVF.
Acrosomal membrane reaction is a method of screening healthy sperm by conducting sperm natural reaction. In IVF surgery, the use of this technology can screen out sperm with vitality and high survival rate, thus improving the success rate of IVF.
Infant culture and transplantation technology
Infant culture and transplantation techniques also have an impact on the survival rate of sperm. In IVF surgery, doctors will fertilize healthy sperm and eggs in vitro, and then culture the fertilized eggs in vitro. Professional hospitals usually use advanced culture technology to provide appropriate culture media and conditions to ensure the normal development of fertilized eggs.
When the fertilized egg develops to a certain stage, the doctor will transplant it back to the female uterus to improve the chance of pregnancy again. The success of transplantation technology is related to the quality and quantity of sperm. Therefore, in the process of infant transplantation, it is very important to select sperm and fertilized eggs with high vitality to improve the success rate of transplantation.
summary
In order to improve the survival rate of IVF sperm, it is necessary to maintain the environmental conditions of sperm vitality, including the control of laboratory environment and storage process. Secondly, the choice of sperm treatment and purification technology is also crucial. Assisted reproductive techniques such as sperm injection and acrosomal membrane reaction can further improve sperm survival rate. The technology of infant culture and transplantation is also an important factor affecting the success of IVF. Through the comprehensive application of these methods and technologies, the sperm survival rate of IVF will be significantly improved, thus improving the birth success rate of infants.
