Spontaneous germ cell death is very important for the removal of germ cells and control of the quantity and quality of sperm. But excessive germ cell death will lead to diminish spermatogenic function and decrease the quality and quantity of sperm. Excessive germ cell death triggered by various regulatory stimuli, including deprivation of gonadotropins and intratesticular testosterone or by estradiol treatment in rats via apoptosis.

生精细胞凋亡是哺乳动物精子发生过程中的一个显著特点，其生理性凋亡对于去除受损的生精细胞，控制细胞数量和保证精子的质量具有重要意义，但生精细胞的过度凋亡可引起生精功能低下，使精子的数量和质量降低。

ABSTRACT Objective To discuss the clinical pathologic features and differential diagnosis of mixed germ cell sex cord stromal tumorwith malignant variant of germ cell tumor Methods The clinical pathologic datum and immunophenotype were studied in the case of ovary MGCSCST with malignant variance of germ cell tumor Results The patient's genital anatomy and female phenotype were normal,karotypes was 46xx with uterogestation The tumor tissue consisted of mixed germ cells and sex cord stromal cells with evident malignancy of mixed germ cells There was no atypical structure of gonadoblastoma in tumor tissue Conclusion MGCSCSST has complex morphosis,thus,to prevent misdiagnosis,more samples should be collected and more slices be cut The patient may have prognosis malo when there are high malignant variants of mixed germ cells in tumor tissue

目的 探讨混合性生殖细胞性索间质肿瘤(mixed germ cell sex cord stromal tumor，MGCSCST)伴恶性生殖细胞肿瘤变异型的临床病理特点及鉴别诊断。方法卵巢MGCSCST伴恶性生殖细胞肿瘤变异型的病例进行临床病理特征和免疫表型分析。结果患者生殖器的解剖结构和女性表型正常，染色体组型是46xx，足月妊娠。肿瘤组织由混合性生殖细胞和性索间质肿瘤构成，混合性生殖细胞有显著的恶性特征。瘤组织中没有典型的性腺母细胞瘤结构。结论 MGCSCST有复杂的形态结构，因此更多的取材和切片可以防止误诊，当肿瘤组织中的混合性生殖细胞有高度恶性变异时，患者预后不良。卵巢肿瘤；生殖细胞性索间质肿瘤；免疫组织化学
