What should be paid attention to when storing IVF semen
With the progress of science and technology, IVF technology has enabled many infertile couples to realize their reproductive dreams. The storage of IVF semen is an important step. Correct storage conditions can ensure the quality of semen and the feasibility of preservation. The following details the precautions for the storage conditions of IVF semen in terms of temperature, storage time, sexual life rhythm and available equipment.
1. Temperature
Temperature is one of the important factors affecting semen quality. In order to maintain sperm vitality and reduce metabolic damage, the temperature of semen storage should be kept at 2-8 ℃. In this range, the metabolism of sperm slows down, which can extend the preservation time of semen. Different hospitals and laboratories may have different storage temperature requirements, so before storage, be sure to understand the storage requirements of the hospital or laboratory in detail.
At the same time, in the process of storage, it is necessary to avoid violent fluctuations in temperature. Temperature changes can lead to sperm damage or even death. Therefore, avoid temperature fluctuations in storage conditions.
2. Storage time
The storage time is another important factor for semen preservation. Generally, the longer the semen is stored, the lower the sperm survival rate will be. It is recommended to use within 48 hours after semen storage to ensure the best pregnancy effect. If the storage time is too long, the vitality and fertility of sperm will be seriously reduced.
In addition, frequent transfers should also be avoided during storage. Frequent transfer will increase the risk of semen damage and affect the quality and feasibility of semen.
3. Sexual life rhythm
In the early treatment of IVF, many couples need to take eggs and semen. Therefore, before starting treatment, you need to understand your own sexual life rhythm, and reasonably allocate sexual life time under the guidance of doctors.
It is generally recommended that there should be no sexual life for 2-5 days before the sperm removal or egg removal operation. This is to ensure the quality of semen and reduce the risk of possible infection. During this period, the number of sperm in the body will increase, and sperm vitality will increase, which will help improve the chance of pregnancy.
It should be noted that too long or too short abstinence period may have adverse effects on pregnancy. Therefore, when formulating the rhythm of sexual life, we should make reasonable arrangements according to our own conditions and the doctor's suggestions.
4. Available equipment
Special freezing tubes or containers are usually used for the storage of IVF semen. These containers are specially treated to maintain the quality of semen at low temperatures. When storing, ensure that the containers used are clean, dry and free from damage and pollution.
In addition, attention should be paid to the marking and recording of storage containers. During storage, the source, storage time and other necessary information of semen should be correctly marked so that the required information can be quickly and accurately obtained during subsequent use.
Summary
The storage condition of IVF semen is very important, which is directly related to the pregnancy effect and the smooth medical process. In the process of storage, the control of temperature, the assurance of storage time, the reasonable rhythm of sexual life and the correct use of equipment are all points that need attention. Only by strictly following the storage conditions can we ensure the successful implementation of IVF technology.
