Methods for collecting semen of test tube infants
IVF is a kind of assisted reproductive technology, which usually needs to collect and process semen. The following is a detailed introduction to the collection methods of IVF semen from four aspects.
1. Selection of semen collector
The semen collector is a special container for collecting semen samples. At present, two types of semen collectors are commonly used in hospitals and reproductive centers.
The first is a sealed container to prevent semen from contacting the air, such as an airtight collector. The collector can ensure that the semen sample is free from external pollution during the collection process, and improve the quality of the collected sample.
The second is an open collector, such as glassware. This collector usually does not contact harmful substances on the surface of semen, but it also needs to use appropriate devices to keep the collection environment clean.
No matter what type of semen collector is used, doctors and nurses should follow strict hygiene requirements and operating specifications to ensure the accuracy and safety of semen samples.
2. Semen collection method
The time and place of semen collection have an important impact on the quality of samples collected. The best time to collect semen is after waking up in the morning, because the concentration of semen is the highest at this time. At the same time, the acquisition process is best carried out in a pressure free and interference free environment to improve the success rate.
The following are general semen collection methods:
1) Clean the external genitals first to ensure that there is no residue.
2) Stimulate the head of the penis using the given semen collector, for example by hand or by sexual stimulation with a partner.
3) When the semen begins to flow out, place the container on the penis head and collect the semen until the sample is completely collected.
4) Cover the collected semen sample tightly, and then send it to the hospital or reproductive center for further processing and analysis.
3. Storage and transportation after collection
After semen collection, the sample needs to be stored and transported to the reproductive center or laboratory for analysis. Here are some considerations:
1) Semen samples should be sent to the reproductive center or laboratory immediately after collection.
2) The storage temperature of samples should be between 2 ° C and 8 ° C to avoid freezing or excessive temperature.
3) The semen sample should be sent to the laboratory within 1 hour after collection to ensure the best vitality of the sample.
4) During transportation, the sample needs to be protected from severe vibration, so as not to affect the sperm quality.
4. Hospital services and privacy protection
When choosing a hospital or reproductive center for IVF, it is very important to consider the services provided and privacy protection.
1) High quality hospitals or reproductive centers should provide professional IVF services and have advanced equipment and technology.
2) Hospitals or reproductive centers should ensure that patients' privacy is protected when collecting, storing, and handling semen samples.
3) The hospital or reproductive center should fully communicate with patients and explain the collection process and possible risks to them to ensure informed consent of patients.
To sum up, the collection methods of IVF semen include selecting appropriate semen collectors, paying attention to the collection time and environment, and precautions for storing and transporting semen samples. It is also very important to choose a reliable hospital or reproductive center to provide professional services and privacy protection.
