Effect of low sperm motility on test tube infants
IVF is an assisted reproductive technology that helps couples who cannot conceive naturally realize their dreams of pregnancy through in vitro fertilization. However, low sperm activity may affect the success rate and health of IVF. This will be elaborated from four aspects: sperm quantity, sperm quality, success rate and health problems.

1. Number of sperm
The number of sperm is an important factor affecting the success rate of IVF. When male sperm vitality is low, it is often accompanied by a decrease in the number of sperm. This means that the number of sperm available for selection is limited during in vitro fertilization. This is a challenge for IVF, because the reduction of sperm number will lead to a lower success rate.
In some cases, special techniques may be needed to increase the number of sperm, such as sperm donation or extraction of more sperm for in vitro fertilization. Although these techniques can solve the problem of insufficient sperm quantity, the vitality and quality of sperm still need to be fully considered.
2. Sperm quality
Low sperm activity will also affect sperm quality, even if the number of sperm is sufficient. Low sperm vitality means that the motility of sperm is weakened, which may lead to sperm unable to pass through the ovarian tube to reach the egg. This has a direct impact on the success rate of IVF.
In addition, low sperm motility may also lead to abnormal sperm morphology, such as head deformation, tail defect, etc. This abnormal sperm often cannot successfully combine with the egg, thus affecting the process of fertilization. Therefore, in the process of IVF, low sperm activity may lead to a reduction in the success rate of fertilization.
3. Success rate
Low sperm motility has a direct impact on the success rate of IVF. Low sperm activity will reduce the selection range of sperm during in vitro fertilization, thus reducing the possibility of successful fertilization. Although modern medical technology can help to deal with the problem of low sperm vitality, the success rate is still limited to a certain extent.
In addition, even if fertilization occurs, low sperm activity may affect the quality and development ability of the fertilized eggs, thus further reducing the success rate of IVF. Therefore, before IVF, it is necessary to fully evaluate the male sperm vitality and other related factors, so as to improve the success rate.
4. Health problems
Low sperm motility may also have some impact on the health of IVF. Low sperm motility means that the DNA quality of sperm may be poor, which increases the risk of chromosomal abnormalities in IVF. Chromosome abnormalities may cause embryos to stay in the early development stage, or even lead to abortion or congenital malformations.
In order to reduce this risk, some hospitals will carry out a series of screening and testing to exclude embryos with chromosome abnormalities, thus improving the health rate of IVF. However, low sperm motility may still increase the risk of chromosomal abnormalities, so this should be highlighted during IVF.
summary
The influence of low sperm motility on IVF is mainly reflected in four aspects: sperm quantity, sperm quality, success rate and health problems. The decrease of sperm number and motility caused by low sperm motility will reduce the success rate of IVF. In addition, low sperm activity may also lead to chromosomal abnormalities, affecting the health of IVF. Therefore, before IVF, couples with low sperm motility should seek the help of professional hospitals to assess the possible risks and develop appropriate treatment plans to improve the success rate and health of IVF.
