    2, past medical history: Is it suffered from gonorrhea, mumps, tuberculosis, epididymitis, prostatitis, pyelonephritis, cystitis or spinal cord injury, with or without dysuria, with or without diabetes or hypothyroidism, etc. and the effect of the treatment conditions .

     4, past examination and treatment: The man's semen test results, time and method of collection; and whether treatment effectiveness; woman inspections.
    5, family history: family, whether infertility, gender malformations, genetic diseases, and tuberculosis patients.
Second, physical examination
Including systemic and genital examination. Medical check-up with the medicine the same way, with particular attention to growth, nutrition and mental condition, but the focus is a genital examination, inspection include:
1, penis: watch for severe phimosis, induration, inflammation, tumors or developmental abnormalities.
2, urethra; whether the fistula hole, hypospadias, induration and so on.
3, prostate: After DRE can check its size, with or without sclerosis, tumor, but also to take prostate massage fluid examination.
4, testis: measurement of their size, hardness, palpation, with or without induration, tenderness, mass, whether cryptorchidism.
5, spermatic cord: touching which the hardness of the vas deferens, with or without nodules, tenderness, with or without varicocele.
Third, laboratory tests
In addition to semen as a necessary check items, the rest depends on the specific situation in patients with a choice:
1, semen analysis: This will help to understand the male fertility, male infertility is a necessary check items and check the contents, including color, volume, liquefaction time, pH, sperm count, motility, viability and morphology.
2, in vitro fertilization experiment heterogeneous: even completely normal routine semen analysis, but sometimes it still can not fully representative of sperm fertilization capacity. Heterogeneous in vitro fertilization experiments can more accurately estimate the fertilization ability of sperm, right to judge men's fertility was extremely valuable and commonly used is a human hamster egg sperm penetration heterogeneous fertilization experiment in the normal fertile sperm as controls.
3, prostate fluid examination: normal for the milky white, alkaline, high-powered microscope, full view of the small, refractive index of lecithin granules, a few epithelial cells, starch-like body and sperm, white blood cell count is less than 10/HP, there is inflammation increase in the number of white blood cells, or even to see the piles of pus cell, lecithin granules significantly reduced.
4, endocrine examination. By gonadotropin-releasing hormone and other tests, can understand the hypothalamus - pituitary - testicular axis function. Determination of testosterone levels can be a direct response to stromal cell function. Can be determined, if necessary, thyroid hormones, adrenal hormones, or prolactin sebum.
5, Doppler ultrasound examination.
6, X-ray examination. To determine the vas deferens obstruction Road site, can use the vas deferens, epididymis imaging, vas deferens, seminal vesicles or the urinary tract imaging such as imaging, photo sella hyperprolactinemia by X-ray tomography films (positive, side view) to determine whether pituitary adenoma .
7, immunological examination. Sperm agglutination test or by braking test for detection of serum or seminal plasma sperm antibodies agglutination antibody or braking. There are several detection methods should be chosen according to local conditions.
8, testis biopsy. Azoospermia azoospermia or less for a direct examination of the testicular seminiferous tubules of spermatogenic function and the development of interstitial cells, localized hormone synthesis and metabolism may, by immunohistochemical staining reflected.
9, chromosome karyotype analysis. For external genital abnormalities, testicular hypoplasia and azoospermia of unknown origin.
