The way of sperm extraction from test tube babies
IVF is a kind of assisted reproductive technology, which combines sperm and egg in a test tube, and then transfers the embryo back to the mother to achieve pregnancy. So, what are the sperm extraction methods of IVF? The following will be elaborated from four aspects.
1. Natural ejaculation
Natural ejaculation is a common method for IVF sperm extraction. In this method, men discharge sperm when their genitals naturally erect and reach orgasm. Sperm collection can be completed independently in the hospital or at home, and the samples can be sent to the hospital for processing. Before handling sperm samples in the hospital, it is necessary to ensure that the semen is clean and collected in sterile containers to avoid bacterial infection. Sperm samples are then sent to the laboratory for further processing.
The advantage of natural ejaculation is that the process of ejaculation is relatively simple and does not require too much medical equipment. However, because men are required to reach orgasm, this method may not be applicable to men with sexual dysfunction.
2. Vaginal self-excited method
Vaginal self excitation is another common method of sperm extraction from test tube infants. In this method, the male stimulates self stimulated orgasm through the penis and collects the discharged semen in a container. Compared with natural ejaculation, vaginal self-excited ejaculation is more convenient for men with sexual dysfunction, because they do not need to achieve natural erection and orgasm.
The quality of semen samples taken by vaginal self-excited method is generally good, but it is also necessary to pay attention to hygiene to ensure that the samples are not contaminated. Men should communicate with doctors in detail to ensure that they get the correct sampling containers and instructions from the hospital.
3. Electric stimulation of penis
Penile electrical stimulation is a method of extracting semen by using electrical stimulation. In this method, the doctor will place an electric stimulator on the male penis to guide ejaculation through appropriate electric stimulation. When men reach orgasm under the stimulation of electrical stimulation, semen will be collected.
The advantage of the penis electrical stimulation method is that there is no need for sexual stimulation and self stimulation. For men with sexual dysfunction, semen extraction is relatively easy. However, this method needs to be carried out in the hospital, which requires the professional operation of doctors, so it needs to be carried out in formal hospitals.
4. Testicular puncture
Testicular puncture is a complicated method of sperm extraction from test tube infants. In this method, doctors will insert a needle into a man's testicle through surgery to extract sperm directly. This method is applicable to men who cannot obtain semen by other methods, such as abnormal sperm development or sperm unable to ejaculate.
Sperm samples taken by testicular puncture are usually of good quality, but there are certain risks due to the need for surgery. Therefore, this method can only be carried out in formal hospitals and requires professional guidance from doctors.
summary
There are many ways to extract sperm from IVF, including natural ejaculation, vaginal self stimulation, penis electrical stimulation and testicular puncture. Each method has its advantages, disadvantages and applicable population. When choosing the method of semen extraction, men should fully communicate with doctors and choose according to their personal conditions and professional guidance. If necessary, formal hospitals should be selected for operation to ensure the safety of semen extraction process and the quality of sampling.
