摘要

受精后，人类精子尾部在原核阶段失去纤维鞘，变成盘绕状，然后附着在第一个有丝分裂纺锤体的一个极上。精子尾的顶端呈分枝状，其程度从原核阶段到第二次有丝分裂期间没有变化。

Morphological analysis of the human sperm tail during the early post-fertilization stage

After fertilization, the human sperm tail lost its fibrous sheath at the pronuclear stage to become coiled and then attached to one of the first mitotic spindle poles. The tip of the sperm tail was branched and its degree did not change from the pronuclear stage to the second mitosis.

期刊介绍： Reproduction is the official journal of the Society of Reproduction and Fertility (SRF). It was formed in 2001 when the Society merged its two journals, the Journal of Reproduction and Fertility and Reviews of Reproduction. Reproduction publishes original research articles and topical reviews on the subject of reproductive and developmental biology, and reproductive medicine. The journal will consider publication of high-quality meta-analyses; these should be submitted to the research papers category. The journal considers studies in humans and all animal species, and will publish clinical studies if they advance our understanding of the underlying causes and/or mechanisms of disease. Scientific excellence and broad interest to our readership are the most important criteria during the peer review process. The journal publishes articles that make a clear advance in the field, whether of mechanistic, descriptive or technical focus. Articles that substantiate new or controversial reports are welcomed if they are noteworthy and advance the field. Topics include, but are not limited to, reproductive immunology, reproductive toxicology, stem cells, environmental effects on reproductive potential and health (eg obesity), extracellular vesicles, fertility preservation and epigenetic effects on reproductive and developmental processes.
