Infertility: How to test if sperm can penetrate a woman's egg
During fertilization, a sperm must first fuse with the plasma membrane and then penetrate the female egg in order to fertilize it. Fusing to the egg usually causes little problem, whereas penetrating through Upon coming into contact with the zona pellucida, the acrosomal enzymes begin to dissolve and the actin filament.
Read and learn for free about the following article: Egg meets sperm. Cortical granules filled with enzymes line the inside of the cell membrane, and will help all of which help sperm penetrate and navigate the female reproductive system.
Acrosome reaction
Sperm require beta-N-acetylglucosaminidase to penetrate through the egg zona acrosome reaction, as expected for an enzyme involved in zona penetration.
Description:By the end of this section, you will be able to: Describe the obstacles that sperm must overcome to reach an oocyte Explain capacitation and its importance in fertilization Summarize the events that occur as a sperm fertilizes an oocyte Fertilization occurs when a sperm and an oocyte egg combine and their nuclei fuse. Because each of these reproductive cells is a haploid cell containing half of the genetic material needed to form a human being, their combination forms a diploid cell.
