Generally speaking, after marriage, there have been no defense measures, and there are no children for more than two years.If the wife is not a problem, the man should go to the hospital for examination in time in order to find out the cause and treat early treatment. The following examinations can be performed in sequentially in the hospital's urology or male department.
1. Laboratory inspection
Except for the semen examination as a compulsory item, the rest should be selected depending on the specific situation of the patient:
1. Semen analysis: This helps to understand the fertility of men. It is a compulsory item for infertility. The inspection content includes color, quantity, liquefaction time, pH, sperm count, activity, survival rate and form.
2. Exposure of in vitro heterogeneity: Even if conventional semen analysis is completely normal, sometimes it is still not possible to represent the essence of sperm.In vitro heterogeneous insemination experiments can more accurately estimate the fertilization ability of sperm, and it is very valuable to judge men's fertility. Commonly uses the heterogeneous insemination experiments of human sperm penetrating hamster eggs, with the sperm of normal fertility as a control.
3. Prostate liquid examination: Normal is milky white, alkaline, and the tiny and folding lecithin particles are seen under high -power mirrors., Or even seeing pour pus cells, lecithin particles are significantly reduced.
Second, endocrine examination.Release hormones or clonetin stimulation tests by promoting gonadotropin, you can understand the function of the hypothalamus-testicular axis.Testosterone levels can directly reflect the function of cells.If necessary, you can determine thyroid hormone, adrenal sebum hormone or prolactin.
3. Doppler ultrasound examination.Help to confirm the varicocele.
Fourth, X -ray check.In order to determine the obstructive area of the vasia pipeline, vasters, epididymal angiography, vascus tubes, seminal vesicles, or urethral angiography can be used.Essence
Fifth, immunology examination.Detecting sperm coagulation antibodies or braking antibodies in serum or slurry in the sperm condensing test or braking test.Although there are many types of detection methods, it should be selected according to local conditions.
Six, testicular biopsy.For sperm non -sperm or sperm, directly check the sperm function of the testicular sperm tubular and the development of interior cells. The synthesis and metabolism of local hormones can be stained by immunohistochemistry.
Seven, chromosome nuclear analysis.For external reproductive organs, testicular dysplasia, and unknown sperm -free.
