In vitro xenofertilization experiments

In vitro xenogeneic insemination experiments, even though conventional semen analysis is completely normal, sometimes does not fully represent the insemination ability of sperm. In vitro xenogeneic insemination experiments can more accurately estimate the fertilization ability of sperm, which is of great value in judging male fertility. Commonly used is the heterologous insemination experiment of human sperm penetrating hamster eggs, and the sperm of normal fertiles is used as a control. Basic Information Specialist classification: male examination check classification: semen and prostatic fluid examination Applicable gender: whether the male is fasting: not fasting Tips: Before leaving semen, the patient should stop sexual intercourse for 4 to 7 days. Normal value The ability of human sperm to penetrate hamster eggs is consistent with normal fertility. Clinical significance Abnormal results: According to in vitro xenogeneic insemination experiments, sperm fertilization ability can be estimated and male fertility can be judged. People who need to be examined: male infertility. Precautions Taboo before inspection: 1. Before leaving semen, the patient should stop sexual intercourse for 4 to 7 days. Testosterone propionate, testosterone phenylacetate, and nantrolone phenylpropionate could not be used 1 week before the test. Drinking should be stopped within 1 month before the test. This must be done. 2, when taking semen, soft soap or paraffin oil can be used for penile massage, the specimens are collected in sterile test tubes; condoms can be used (washed clean, no spermicide drugs) or semen can be collected by sexual intercourse, but this way The amount collected is often small. 3. If the semen is not obtained by the above method, the seminal vesicle and the end of the vas deferens can be massaged through the rectum, and the urine can be collected to check whether there is sperm in the sediment. 4. Do not expose semen to overheated and cold environments. Hand it to the doctor for reference, no more than 30 minutes. Keep warm in cold weather, and keep it in your underwear pocket when you send it. 5. If bacterial culture is to be carried out, the urethral opening should be rinsed and disinfected, and the semen should be collected in a sterile test tube. Requirements for inspection: If you are not giving birth, both husband and wife must go to check. Inspection process Human sperm penetrated the heterologous insemination experiment of hamster eggs, using the sperm of normal fertiles as a control. Not suitable for the crowd Inappropriate people: not yet known. Adverse reactions and risks There are no related complications and hazards.
