Collection of test tube baby semen
IVF semen is a kind of reproductive mode that male sperm and female egg are fertilized in vitro and then transfused back into female uterus through artificial assisted reproduction technology. Collection of semen is one of the necessary steps in the early stage of IVF. So, what should be paid attention to in the process of IVF semen collection?
First of all, when choosing a hospital to collect semen, you must choose a legal, professional and qualified hospital. In China, there are many famous top three hospitals with qualifications to carry out IVF technology, such as Peking Union Medical College Hospital and Shanghai Fudan University Affiliated Obstetrics and Gynecology Hospital. These hospitals have a high level of medical facilities, technical strength and medical experience, and can provide better services for patients.
Secondly, before the test tube baby semen collection, men should avoid overwork and strenuous exercise, so as not to affect the quality and quantity of semen. In addition, men should pay attention to maintaining the law of life before collection, and avoid staying up late and staying under high pressure for a long time. These factors can have a certain impact on the quality and quantity of sperm.
Finally, the collection of IVF semen is a sensitive and private process. The hospital will provide an independent collection room for men, and provide professional equipment and medical staff for guidance. Men need to follow the guidance of medical staff to collect semen into the container and ensure that the collection is complete. In addition, men also need to cooperate with doctors to carry out necessary physical examinations to ensure that their physical conditions are suitable for the implementation of IVF.
Preservation and transportation of test tube baby semen
The preservation and transportation of IVF semen is an important link to ensure sperm quality. After the collection is completed, the hospital will process and preserve the semen to prevent it from losing vitality. Generally speaking, semen is stored in special test tube baby semen preservation solution, and the vitality of sperm is prolonged through scientific preservation conditions.
Temperature and time should be strictly controlled during semen preservation and transportation. Generally speaking, semen preservation solution needs to be stored at low temperature (- 196 ℃ or - 80 ℃) to maintain the biological activity of sperm. In the process of transportation, professional low temperature transportation methods, such as liquid nitrogen tanks or refrigeration equipment, should be used to avoid interference from temperature changes and vibration.
In addition, the preservation and transportation of semen also need to pay attention to protective measures to avoid contamination and infection. The hospital will use sealed containers for preservation, and preserve them in a clean and sterile environment to ensure the purity of semen. At the same time, medical staff also need to follow strict hygiene requirements during operation, such as wearing gloves, masks, etc., to prevent the contamination and spread of pathogens.
Quality evaluation of test tube infant semen
The quality evaluation of IVF semen is an important means to judge sperm vitality and fertilization ability. Usually, the hospital will conduct a series of examinations and evaluations on the semen collected to understand the number, vitality, morphology and other indicators of sperm.
Common semen quality evaluation indicators include sperm concentration, total semen, sperm motility and sperm morphology. These indicators can be obtained through microscopic observation, calculation and statistics, and compared with normal values. By evaluating the quality of semen, doctors can be provided with more accurate diagnosis and treatment plans, and the success rate of IVF can be improved.
When conducting semen quality assessment, medical staff need to strictly abide by the operating specifications to ensure accurate and reliable results. At the same time, the interpretation of the evaluation results also needs an experienced professional doctor to analyze and provide targeted suggestions and treatment plans.
Use and precautions of test tube baby semen
The use of IVF semen is the core of IVF technology. The doctor will conduct in vitro fertilization of the collected semen with high vitality and good shape with female eggs, and then return it to the female uterus for pregnancy.
Before using semen, the hospital will handle and prepare it, including centrifugation, cleaning and dilution. These processes aim to improve the purity and vitality of semen to increase the success rate of fertilization.
During the use of IVF semen, doctors need to develop personalized medical programs according to the specific conditions of patients, such as fertilization methods (conventional in vitro fertilization or single sperm injection) and fertilization cycles. At the same time, patients and doctors also need to cooperate closely, follow doctors' orders, treat on time, and inform doctors of abnormalities in the treatment process.
To sum up, the collection, storage and transportation, quality assessment and use of IVF semen are all indispensable links in IVF technology. Following doctors' guidance and standardized operation can improve the success rate of IVF and help more infertile patients achieve their reproductive dreams.
