How to select sperm suitable for IVF
In vitro fertilization (IVF) is a kind of assisted reproductive technology. It is a process of pregnancy through in vitro fertilization of sperm and eggs, and then transfer the fertilized eggs to the mother's uterus. The selection of sperm suitable for IVF is an important step to ensure the success of reproduction. Here we will discuss how to select suitable sperm from four aspects.
1. Select matched genetic characteristics
Sperm carries the genetic information of male individuals, including genes, DNA sequences, etc. When selecting sperm, it is necessary to consider the genetic characteristics of matched genes. First of all, it is necessary to understand the history of genetic diseases of patients and their families, such as chromosome abnormalities, genetic diseases, etc., to eliminate the risk of transmission to offspring. Secondly, it is necessary to select appropriate genetic characteristics, such as height, appearance and intelligence, according to the patient's personal preferences and expectations. According to the needs of patients, doctors will select qualified sperm from the sperm bank for patients to choose.
In addition, some hospitals also provide genetic counseling services to provide more accurate genetic feature matching services for patients through the professional knowledge and technology of geneticists. Patients can select suitable sperm according to the doctor's suggestions to improve the genetic quality of IVF.
2. Consider the quality and quantity of sperm
The quality and quantity of sperm have an important impact on the success rate of IVF. Selecting sperm with high quality and quantity can improve the quality and quantity of fertilized eggs and increase the success rate of pregnancy. Generally speaking, sperm quality assessment includes morphology, motility and concentration. Morphological evaluation can be conducted by sperm morphology, and motility evaluation can be conducted by sperm viability test or sperm motility observation.
When selecting suitable sperm, we can refer to the sperm quality report and relevant data provided by the hospital. Some hospitals also provide pre implantation genetic screening (PGS) services, which can screen sperm for chromosomal abnormalities, so as to improve the success rate of IVF.
3. Ensure the safety of sperm
Safety is also one of the factors to be considered when selecting suitable sperm. The hospital needs to ensure that the source of sperm is legal and reliable, and that it has undergone relevant virus and infection screening to avoid transmitting harmful viruses or infections to the mother or pregnant women. Some hospital sperm banks have strict sperm collection, preservation and screening procedures to ensure the safety of sperm.
In addition, some hospitals also provide sperm storage services, that is, male sperm is stored in liquid nitrogen for future use. Patients can choose their own suitable sperm for storage, so that IVF treatment can be carried out at any time.
4. Consider the affinity between sperm and female physique
The affinity between sperm and female physique is also an important consideration in selecting suitable sperm. Affinity includes not only gene affinity, but also immune affinity. Some hospitals provide semen immunological tests to assess the affinity of sperm and female immune system. If there is improper immunity, sperm may be attacked by the female immune system, thus affecting fertilization and pregnancy.
When selecting suitable sperm, doctors will provide personalized selection suggestions for patients based on women's physique and sperm affinity, taking into account factors such as genetic characteristics, sperm quality and quantity.
summary
The selection of sperm suitable for IVF is an important step to ensure the success of IVF. The accuracy and success rate of selecting suitable sperm can be improved by comprehensively considering the genetic characteristics of matched genes, the quality and quantity of sperm, the safety of sperm, and the affinity between sperm and female physique. Choosing the right sperm means providing better genetic quality and pregnancy success rate for IVF, and creating better conditions for patients to achieve their dream of healthy babies.
