acrosome reaction









































during fertilization, a sperm must first fuse with the plasma membrane and then penetrate the female egg cell in order to fertilize it. fusing to the egg cell usually causes little problem, whereas penetrating through the egg's hard shell or extracellular matrix can present more of a problem to the sperm. therefore, sperm cells go through a process known as the acrosome reaction which is the reaction that occurs in the acrosome of the sperm as it approaches the egg. the "acrosome" is a cap-like structure over the anterior half of the sperm's head.

acrosome









































the acrosome is an organelle that develops over the anterior half of the head in the spermatozoa (sperm cells) of many animals including humans. it is a cap-like structure derived from the golgi apparatus. acrosome formation is fully completed 5–10 years after testicular maturation. in eutherian mammals the acrosome contains digestive enzymes (including hyaluronidase and acrosin). these enzymes break down the outer membrane of the ovum, called the zona pellucida, allowing the haploid nucleus in the sperm cell to join with the haploid nucleus in the ovum.
