Is there any requirement for sperm quality of IVF?
Test tube baby is an assisted reproductive technology, which combines sperm and eggs through artificial insemination, and finally transplants them to the mother to achieve pregnancy. In the process of IVF, sperm quality plays an important role in the success rate. The following will elaborate on the sperm quality requirements of IVF from different aspects.
Number of sperm
Before IVF, doctors will first conduct semen analysis on the man, mainly checking the number of sperm, which is one of the important factors determining whether IVF technology can be used. Generally speaking, more than 15 million sperm are required per milliliter of semen to ensure sufficient quantity for fertilization. If the number of sperm in semen sample is lower than this standard, the success rate of IVF will be lower.
Moreover, the number of sperm will also affect the potential for obtaining healthy embryos. As the number of sperm increases, the chances of obtaining high-quality embryos will also increase. Therefore, the requirements for sperm quality not only require sufficient quantity, but also require excellent quality to improve the success rate of IVF.
Sperm motility
Sperm motility is one of the important indexes to judge sperm quality. The doctor will check the motility of the sperm to assess its swimming speed and activity. Generally speaking, at least 50% of spermatozoa should have good swimming ability so that they can successfully enter the egg during fertilization. If the sperm vitality is insufficient, it will affect the success rate of fertilization.
The lack of sperm vitality may be caused by many factors, such as bad living habits, health problems, environmental factors, etc. In the process of IVF, doctors will give corresponding treatment and suggestions to improve sperm vitality and the success rate of IVF.
Sperm morphology
In addition to quantity and vitality, sperm morphology is also an important indicator of sperm quality. Sperm morphology is usually evaluated according to the shape and structure of the head, neck and tail. The morphology of normal sperm should be more than 30%. If there are too many abnormal sperm, the success rate of fertilization will be affected.
Bad sperm morphology may be related to genetic factors, environmental exposure, living habits, etc. In the process of IVF, doctors can give corresponding suggestions and treatment according to the specific situation to improve the sperm morphology and increase the success rate of IVF.
Sperm DNA integrity
The integrity of sperm DNA is another important factor in evaluating sperm quality. If sperm DNA is damaged or missing, it will affect the normal development of the embryo and the success of pregnancy. Therefore, the requirements of sperm quality also include the integrity of sperm DNA.
Doctors can assess the integrity of sperm DNA through sperm DNA fragmentation test. If the degree of sperm DNA fragmentation exceeds a certain standard, corresponding treatment measures need to be taken to improve the integrity of sperm DNA.
Summary
To sum up, the sperm quality of IVF is very important, which is directly related to the success rate of IVF. The requirements for sperm quality include adequate quantity, good vitality, normal morphology and DNA integrity. Through comprehensive evaluation and treatment of sperm quality, the success rate of IVF can be improved and more couples can realize their reproductive dreams.
