Story of sperm cell and egg

Researchers at the Swedish medical university Karolinska Institutet have been able to describe the 3D structure of a complete egg receptor that binds sperm at the beginning of fertilization. The results, published in the journal Cell , will lead to better understanding of infertility and may enable entirely new types of contraceptives. For centuries, the imagination of people has been grasped by the encounter of gametes -- egg and sperm-, whose union gives rise to a new individual. At the beginning of conception, sperm binds to proteins in the extracellular coat of the egg, called zona pellucida ZP. But the molecular details of this fundamental biological event have so far remained obscure.
