As you know, to check male fertility, all semen tests are performed. How is a semen test done? Some people say they use electrical stimulation, some say the nurse helps to take, some say they solve it directly in the toilet itself, and some say they have to do surgery to take, so, in the hospital sperm extraction in the end how to take, the following for you to unveil the mystery of the sperm extraction process (minors under 18 years old, please consciously skip) The choice of sperm extraction methods Simply speaking, the main sperm extraction methods are masturbation sperm extraction, sperm extraction instrument assisted sperm extraction, sperm extraction in the same room as the couple, electrical stimulation sperm extraction and surgical sperm extraction. The choice of sperm retrieval methods varies according to the needs. If you are doing IVF and the previous methods are not successful, you can also use electrical stimulation and surgical sperm retrieval (to be determined by the doctor and the patient). Sperm retrieval by staff? It’s just a rumor. ”There are rumors that sperm donation is carried out with the help of staff members, and there are also so-called “beautiful women taking ‘sperm’ pictures” circulating on the Internet. The donor has to be ‘self-reliant’. Whether you are donating sperm at a sperm bank or checking your semen at a hospital, the sperm retrieval process will not and cannot be helped by staff. Masturbation is the simplest and easiest method of sperm retrieval and is the most adopted method of sperm retrieval. You can retrieve it yourself in a dedicated sperm retrieval room or in the toilet. In many places, sperm is obtained in the bathroom, but this method is very limited in terms of protecting patient privacy. People come and go in the bathroom, which has a great impact on the sperm retrievers. For humane reasons, the Reproductive Center of Sun Yat Sen Memorial Hospital of Sun Yat-sen University has a special sperm retrieval room for patients who come to the clinic. The sperm retrieval room is simply arranged with a sofa bed, hand sanitizer, hand sink, trash can, and tissue box. The walls are decorated with pictures of beautiful women or videos to help get into the mood. Sperm Retrieval Instrument Assisted Sperm Retrieval Many patients have concerns that it is difficult to retrieve sperm on their own and how they can’t get it out. Many fertility centers have had patients who ended up needing surgery to retrieve sperm because they had difficulty retrieving sperm on their own. Sun Yat-sen Memorial Hospital of Sun Yat-sen University has introduced a multi-functional automatic sperm retrieval machine to its reproductive center. The super large screen, adjustable and controllable massage frequency, pink body, super intelligent humanized design …… Yes, you read it right, this is the “miracle” automatic sperm retrieval machine that is infinitely “worshipped” by netizens. This “miracle” screen can play art movies, headphones can be connected to listen to surround sound, there is a high simulation of female genital tract massager under the machine, can adjust the speed frequency, in the process of sperm extraction, the machine massage pipe will simulate the physiological sensations of married life, help patients get into the state as soon as possible, can give patients a better sperm extraction experience, especially to solve the problem of many patients with sperm extraction difficulties, to a large extent It avoids the damage caused by having to surgically puncture the testicles or epididymis to retrieve sperm. After each use, there is a person to disinfect and replace the utensils, because ordinary condoms have spermicidal ingredients, so the use of sperm extraction machine must use a special condom without spermicidal ingredients (single-use), so as not to affect the results of semen examination. Sperm retrieval from the same room as husband and wife Patients who have difficulty retrieving sperm on their own can choose to retrieve sperm from the same room as husband and wife. They can take a special sperm cup from the doctor’s office to retrieve sperm at home (or at a hotel near the hospital). The sperm must be sent to the laboratory within 1 hour after retrieval. The semen specimen should not be exposed to too high or too low a temperature, and the transported semen should be kept warm against the body (not in a bag or paper bag). Electrical stimulation for semen retrieval (EEJ) is used to achieve the effect of inducing ejaculation by means of direct current stimulation. For infertility caused by non-ejaculation or when artificially assisted reproduction is used to treat infertility, ejaculation needs to be induced, and the help of a device such as an electronic ejaculator is needed in this case. The electronic ejaculator helps ejaculation in a wide range of applications, mainly for patients with insemination, such as those with recalcitrant insemination (those for whom conventional treatment is ineffective), those with high paraplegia, those who are unable to ejaculate after retroperitoneal lymph node dissection; those with cancer before marriage who need to preserve semen; those with diabetes secondary to insemination and those with brain death who have a need for artificial insemination, all of whom can ejaculate smoothly with the help of the electronic ejaculator. Surgical sperm retrieval For patients who are unable to retrieve sperm by conventional methods or have azoospermia, surgical sperm retrieval can be used for IVF. Preparation before sperm retrieval Do I have to prepare before sperm retrieval? Yes, abstinence is required for 2-7 days before sperm retrieval, of which 3-5 days is best. Many patients do not understand this point and come here for examination, some have been abstinent for half a month, some just had intercourse last night, in these cases the semen test results have very little clinical reference significance, the result is often the patient took time off work to come, but it was a wasted trip. If you want to do artificial insemination or IVF, your vulva must be clean (soap and chemicals such as shampoo, detergent and lubricants are not allowed to rub the penis to take sperm, as they can kill sperm when mixed with semen). Please check the name on the sperm collection cup carefully before taking the sperm. Open the lid of the cup only before sperm extraction. Cover the lid immediately after sperm extraction. Notes on the sperm retrieval process 1. It is very important to collect all the ejaculated semen, especially the anterior part of the semen. The semen is discharged in a certain order, with the first part coming from the prostate, epididymis and jugular, accompanied by a large number of spermatozoa, and the last part from the seminal vesicles, so the whole semen should be collected and no part should be missed, especially the first part. Because the first part of semen is easily lost, it is not recommended to collect semen by in vitro ejaculation. 2. The sperm collection cup is a disposable sterile cup. After opening the plastic package, be careful not to touch the edge of the cup, the inner wall of the cup and the inner surface of the lid (the penis should not touch the inside of the cup), with the inner surface of the lid facing upwards to avoid contamination. 3, if the sperm is taken for artificial insemination or IVF, the aseptic requirements of the sperm extraction operation are more stringent: do not touch the inside of the cup; the semen spilled out of the cup should never be put back into the cup. Take care to avoid pubic hair, clothing fibers, etc. from falling into the semen cup. If you find any, please ring the bell above the transfer window once in time, and the technician will replace another sperm collection cup for you and collect again. Immediately after the sperm collection, you should cover the lid of the cup, ring the bell above the transfer window once, wait for the laboratory technician to receive the specimen and confirm and sign in person, and keep a small amount of semen specimen for preservation, mainly for the identification of parentage. Many male friends are very worried before doing IVF, worrying that their sperm retrieval will be a difficult task and the embarrassment caused by a failed sperm retrieval on site. IVF is a highly precise procedure, but in regular IVF operating units, the success rate can be basically guaranteed by receiving pre-operative examinations and formal IVF trial cycle operations in strict accordance with the doctor’s instructions, and men who want to do IVF do not need to worry too much because of the procedure.
