精子发生

Spermatogenesis is the process by which sperm cells are produced in the testes of males.
精子发生是指在男性睾丸中生成精子的过程。
During spermatogenesis, diploid spermatogonia differentiate into haploid spermatozoa.
在精子发生过程中，二倍体的精原细胞分化为单倍体的精子。
Spermatogenesis begins during puberty and continues throughout a man's reproductive life.
精子发生始于青春期，并在整个生育期持续进行。
The first stage of spermatogenesis involves mitosis of primary spermatocytes, leading to the formation of secondary spermatocytes.
精子发生的第一个阶段是初级精母细胞进行有丝分裂，从而形成次级精母细胞。
In spermatogenesis, meiosis occurs in the secondary spermatocytes, resulting in four genetically unique sperm cells.
在精子发生过程中，次级精母细胞会发生减数分裂，最终产生四个具有遗传多样性的精子细胞。
Spermatids, which arise from the secondary spermatocytes, undergo complex morphological changes in the final stages of spermatogenesis.
由次级精母细胞形成的精子原细胞，在精子发生过程的最后阶段会经历复杂的形态变化。
Spermiogenesis is the phase of spermatogenesis where spermatids transform into mature spermatozoa.
精子变形期是精子发生的一个阶段，其中精子原细胞转变为成熟的精子。
Hormones such as testosterone play a crucial role in regulating spermatogenesis in the male body.
类似于睾酮的激素在调节男性体内精子发生过程中起着关键作用。
Impaired spermatogenesis can lead to infertility issues in men due to low sperm count or poor sperm quality.
精子发生障碍可能导致男性由于精子数量低或精子质量差而出现不育问题。
FSH (follicle-stimulating hormone) and LH (luteinizing hormone) secreted by the pituitary gland contribute to the regulation of spermatogenesis.
来自垂体腺分泌的FSH（促卵泡激素）和LH（黄体生成素）对精子发生的调控起着重要作用。
