n.囊胚形成

Blastulation is the first stage of mammalian development, where the sperm fuses with the egg to form a single cell called a zygote.
合子形成是哺乳动物发育的第一阶段，精子与卵子结合成一个单一细胞，即受精卵。
After fertilization, the blastula undergoes rapid cell divisions, eventually forming a gastrula for further organogenesis.
受精后，囊胚经历快速分裂，最终形成原肠胚，用于器官形成。
The blastulation process in sea urchins involves the sperm swimming through the female's mucus to reach and fertilize the egg.
海胆中的合子过程包括精子游过雌性的黏液以到达并使卵子受精。
In invertebrates, blastulation often occurs externally, while in vertebrates, it takes place internally within the female's reproductive tract.
在无脊椎动物中，合子通常在体外发生，而在脊椎动物中，则在雌性生殖道内进行。
Scientists study blastulation to understand the early stages of embryo development and potential genetic abnormalities that can arise during this critical period.
科学家研究合子阶段以理解早期胚胎发育以及在这个关键时期可能发生的遗传异常。
Blastulation is a crucial step in the creation of new life, as it marks the beginning of the embryo's journey towards becoming a fully formed organism.
合子是新生命创造的关键步骤，标志着胚胎向完整有机体发育的起点。
The blastulation process is regulated by various hormonal cues and environmental factors, ensuring proper timing for fertilization.
合子过程受到多种激素信号和环境因素的调控，确保了受精的恰当时机。
Some researchers use blastulation techniques in vitro to study fertilization and early embryo development in a controlled environment.
一些研究人员在体外使用合子技术来研究受精和早期胚胎发育，以实现可控环境下的研究。
Due to advances in reproductive technology, scientists can now manipulate blastulation artificially, allowing for better understanding of embryonic development and potential applications in assisted reproduction.
随着生殖技术的进步，科学家现在可以人工操纵合子，从而更好地理解胚胎发育，并在辅助生殖方面找到应用。
In some cases, blastulation may not occur naturally, leading to infertility or requiring medical intervention, such as in vitro fertilization (IVF) procedures.
在某些情况下，合子不能自然发生，导致不孕或需要医疗干预，如试管婴儿（IVF）程序。
