Methods of sperm extraction from test tube babies
Test tube baby technology is an assisted reproductive technology that helps couples who cannot conceive naturally to achieve their reproductive aspirations. Sperm, as an important germ cell, its extraction method plays a vital role in the success rate of IVF. The following will introduce several common sperm extraction methods for IVF.
Natural ejaculation
Natural ejaculation, also known as masturbation, is a common method of sperm extraction. This method requires men to abstain for a period of time before collecting sperm to ensure the concentration of semen. The men then collected semen samples in sterile containers through hand-held masturbation or manual methods. In the process of sample collection, care should be taken not to pollute the container so as not to affect subsequent operations. In addition, during sampling, special sterile test tubes or instruments can be used to keep the sample clean.
In this extraction method, men can be guided by doctors or midwives to ensure the accuracy and safety of the operation. Natural ejaculation is simple and applicable to most IVF patients.
Vaginal Contamination Act
Vaginal contamination is an extraction method that allows sperm to enter a woman's vagina through sexual intercourse, and then draws sperm samples through the uterus. This method is suitable for men who cannot collect sperm samples through masturbation due to physical reasons.
In this method, couples need to have aseptic sexual intercourse and ensure that it is conducted during the female ovulation period to improve the pregnancy rate. After sexual intercourse, the sperm sample is sucked out by the protruded instrument that enters the uterus through the cervical opening and sent to the laboratory for the baby test tube operation.
Vaginal contamination sampling is simple and convenient, but some individual patients may need additional attention, such as avoiding sexually transmitted diseases, maintaining good privacy and hygiene.
Semen infusion method
The semen infusion method is an extraction method that improves the quality and vitality of sperm by further processing and processing semen directly. This method is applicable to cases where the quality of semen samples is poor or men cannot provide sperm samples by themselves due to special reasons.
In the semen infusion method, semen samples were centrifuged to separate better motile sperm, then stained in the staining solution, and observed and counted under the microscope. Similarly, this method needs to be carried out under sterile conditions to avoid contamination and infection.
The semen infusion method can improve the success rate of IVF and provide patients with higher quality sperm samples.
Testicular ejaculation
Testicular sperm extraction, also known as spermatic cord sperm extraction, is a method of extracting sperm samples directly from the surface of the testes by surgical incision. It is applicable to men whose sperm cannot be discharged naturally due to abnormal reproductive system.
In this method, the doctor will operate the testicle under painless anesthesia, and take out the sperm sample with the help of a microscope. After surgery, patients need to pay attention to recuperation and nursing during the recovery period to ensure the effect of surgery and health.
The testicular sperm extraction method is suitable for some special circumstances, and can provide better sperm quality and vitality samples.
summary
Several common sperm extraction methods for IVF are introduced above, including natural ejaculation, vaginal contamination, semen introduction and testicular ejaculation. Each method has its own applicable situation and key points of operation. In practical application, it needs to be selected according to the specific situation of patients. These sperm extraction methods provide a strong guarantee for the success rate of IVF, and bring good news to those couples who cannot conceive naturally.
