The acrosome is an organelle found in sperm cells, containing enzymes that facilitate fertilization.
精子细胞中有一种称为顶体的细胞器，其中含有促进受精的酶。
During fertilization, the sperm's acrosome reacts with the egg's zona pellucida, dissolving the protective barrier.
在受精过程中，精子的顶体与卵子的透明带接触，溶解其保护层。
The acrosome reaction is a crucial event where the acrosomal enzymes cleave the egg's outer layer, allowing sperm to enter.
顶体反应是关键步骤，顶体内的酶会分解卵子的外层，使精子能够进入。
Scientists study the structure and function of the acrosome to better understand male fertility issues.
科学家研究顶体的结构和功能，以更好地理解男性不育问题。
In assisted reproductive technologies, doctors may manipulate the acrosome reaction to improve sperm-egg fusion rates.
在辅助生殖技术中，医生可能会操控顶体反应来提高精子与卵子融合的效率。
Successful fertilization often depends on the integrity of the sperm's acrosome and its ability to perform the acrosome reaction.
成功的受精往往取决于精子顶体的完整性及其进行顶体反应的能力。
The acrosome also contains a variety of proteins that play roles in sperm chemotaxis and recognition.
顶体还含有多样化的蛋白质，参与精子的趋化性和识别过程。
Researchers have developed drugs targeting the acrosome for potential treatments in infertility and other male reproductive disorders.
研究人员已经开发出针对顶体的药物，用于治疗不孕和其他男性生殖障碍。
After ejaculation, the acrosome begins to degrade, ensuring that only healthy sperm can participate in fertilization.
射精后，顶体会开始分解，确保只有健康的精子能参与受精过程。
The study of acrosomes has provided insights into the intricate dance of sperm and egg interaction during fertilization.
对顶体的研究揭示了精子和卵子在受精过程中复杂互动的奥秘。
