目的：探讨不育男性５项内分泌激素与精子密度的相关关系。方法：采取放免法（ＲＩＡ）对１１０例男性不育症进行卵泡刺激素（ＦＳＨ）、黄体生成素（ＬＨ）、催乳素（ＰＲＬ）、雌二醇（Ｅ２）、睾酮（Ｔ）的测定，实验值与同期检测的精子密度进行统计学相关分析。结果：＜４．６μｇ／Ｌ的Ｔ值与精子密度的等级相关系数ｒ＝０．７６０７（Ｐ＜０．００１）；＞１０Ｕ／Ｌ的ＦＳＨ、ＬＨ值与精子密度的等级相关系数分别是ｒ＝－０．５２８３（Ｐ＜０．００１）、ｒ＝－０．４５３１（Ｐ＜０．００５）。结论：低于正常的Ｔ值与精子密度呈正相关；高于正常的ＦＳＨ、ＬＨ值与精子密度呈负相关。
Objective: To investigate the relationship between infertile male five endocrine hormones and sperm density. Methods: 110 cases of male infertility were treated with radioimmunoassay (RIA). The levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin (PRL), estradiol (E2) and testosterone (T) The correlation between the experimental value and the sperm concentration detected in the same period was statistically analyzed. Results: The correlation coefficient between the value of <4.6μg / L T and the sperm density was 0.7607 (P <0.001), and the correlation coefficients of FSH, LH and sperm density of> 10U / L were r = -0.5283 (P <0.001), r = -0.4531 (P <0.005). CONCLUSION: The subnormal T value is positively correlated with sperm density. Higher than normal FSH, LH value is negatively correlated with sperm density.
