Requirements of IVF for sperm
IVF is a kind of assisted reproduction technology, which combines sperm and egg artificially and cultivates them to the embryonic stage, and then implants the embryo into the mother. The improvement of the success rate and the birth of healthy babies are related to many factors, among which the quality of sperm is crucial to the success of IVF. The requirements of IVF for sperm will be described in detail in the following aspects.
Number of sperm
A successful IVF requires a sufficient number of sperm. In the process of egg retrieval, doctors can obtain a certain number of eggs through ultrasound-guided follicle puncture technology. These eggs need to be combined with sperm to develop into embryos through culture technology. Therefore, the number of sperm is crucial to the success of IVF. Under normal circumstances, 1 ml of semen should contain more than 15 million sperm, of which mobile sperm accounts for at least 40%, so as to ensure sufficient sperm quantity to participate in the fertilization process.
Some hospitals, such as Peking Union Medical College Hospital and Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine, have accumulated rich experience in IVF and can provide resources with excellent sperm quality to ensure the success rate of IVF.
Sperm quality
In IVF treatment, not only sufficient sperm quantity, but also good sperm quality are required. The quality of sperm is mainly reflected in its shape and vitality. Normal sperm can better combine with the egg and provide enough genetic material during fertilization. At the same time, the sperm with high vitality can better penetrate the egg barrier and improve the fertilization rate.
Modern medical technology can determine the morphology and vitality of sperm through the sperm quality evaluation system. Some professional reproductive centers and obstetrics and gynecology hospitals are equipped with high-precision sperm quality detection equipment, which can comprehensively evaluate sperm. By screening high-quality sperm, the success rate of IVF can be improved, and the risk of poor pregnant women and embryonic development defects can be reduced.
Sperm DNA integrity
Sperm DNA is one of the important guarantees for fertility and healthy babies. The integrity of sperm DNA will affect the normal development of embryos. The damage of sperm DNA may lead to habitual abortion, embryo implantation failure and abnormal embryonic development. Therefore, one of the requirements of IVF for sperm is the integrity of DNA.
Some hospitals, such as the Guangzhou General Hospital of the Guangzhou Military Region, can assess the DNA integrity of sperm through sperm DNA fragmentation detection technology. Screening sperm with good DNA integrity can improve the success rate of IVF and reduce the risk of adverse pregnancy outcomes.
Sperm motility
The motility of sperm is one of the important factors that affect the success rate of IVF. Spermatozoa need to have enough mobility to successfully penetrate the egg barrier for fertilization. In the process of embryo implantation, the mobility of sperm will also affect its mobility and implantation ability in the uterus.
Some hospitals, such as the General Hospital of Chengdu Military Region of Chengdu Military Region, have rich experience in screening and evaluation of sperm motility. By screening out sperm with better mobility, the success rate of IVF can be improved, and the possibility of implantation and development can be increased.
Summary
IVF has many requirements for sperm, including sperm quantity, quality, DNA integrity and mobility. Only sperm with these requirements can improve the success rate of IVF and reduce the risk of embryo development defects and adverse pregnant outcomes. Choosing a regular hospital for IVF treatment can ensure the quality of sperm and provide a good guarantee for the birth of healthy babies.
