The process of IVF sperm extraction
IVF technology is a kind of assisted reproduction technology, which combines sperm and eggs in vitro and cultivates them, and then implants the embryos into the mother, so as to realize the fertility desire of infertile couples. In IVF technology, semen extraction is a very important step. The process of IVF sperm retrieval will be described in detail below.
Select semen extraction mode
In vitro sperm retrieval can be carried out by natural ejaculation, manual stimulation of ejaculation and testicular aspiration. According to the specific situation of the patient and the doctor's advice, select the appropriate method of semen extraction.
Natural ejaculation refers to the collection of semen for IVF operation during ejaculation. This method does not require special equipment and technology, but requires patients to have good self-control. Manual stimulation of ejaculation is to stimulate the patient's external genitalia to achieve the purpose of ejaculation. This method is applicable to men whose ejaculation function is limited, but there are available sperm in the semen.
Testicular aspiration is a kind of operation, through puncturing the testicle, to extract sperm. This method is applicable to those patients who are unable to perform natural or manual stimulation of ejaculation due to sperm delivery barrier or sperm production reduction. Testicular aspiration should be performed by professional medical personnel under sterile conditions.
Inspection and preparation
Before IVF sperm extraction, patients need to undergo a series of examinations to assess fertility and determine the best method of sperm extraction. These examinations include semen analysis, testicular ultrasound, reproductive hormone examination, etc. Semen analysis can evaluate the number, vitality and morphology of sperm, and provide reference for selecting appropriate sperm extraction methods. Testicular ultrasound can examine the structure and blood flow of the testis. Reproductive hormone test can evaluate the reproductive function of patients. According to the examination results, the doctor will develop a personalized semen extraction program for the patient.
Before IVF sperm retrieval, patients need to make some preparations. First, keep good living habits, pay attention to diet, nutrition and regular work and rest. Secondly, avoid contact with harmful substances, such as nicotine, alcohol, etc. Finally, according to the doctor's advice, stop or adjust some drugs that may affect sperm quality.
Sperm extraction process
Sperm extraction is generally carried out in the sterile operating room of the hospital or clinic. First, the patient needs to remove the lower body clothes and carry out personal hygiene. Then, doctors use sterile containers to collect semen, which can be obtained through natural ejaculation, manual stimulation of ejaculation or testicular aspiration. The semen extraction process requires the patient to keep relaxed and avoid tension and pressure.
The semen collected will be sent to the laboratory for sperm quality analysis. According to the quality and quantity of sperm, the doctor will determine whether sperm extraction or standby is necessary. If there is no available sperm in the semen, sperm extraction techniques, such as follicular cell extraction or testicular sperm extraction, can be carried out to obtain available sperm. The spare semen will be used in future IVF operations.
summary
IVF sperm retrieval is an important step in assisted reproductive technology. The success rate of IVF can be improved by selecting appropriate sperm retrieval methods, conducting relevant examinations and preparations, and carefully operating the sperm retrieval process. However, the situation of each patient is different, so it is recommended that the IVF semen extraction should be carried out under the guidance of a professional doctor.
