Abstract
Upon fertilization, the sperm nucleus undergoes reactivation. The pore less sperm nuclear envelope is replaced by a functional male pronuclea r envelope and the highly compact male chromatin decondenses. Here som e recent evidence is examined: that disassembly of the sperm lamina is required for chromatin decondensation, that remnant portions of the s perm nuclear envelope target the binding of egg membrane vesicles that form the male pronuclear envelope, that functional male pronuclear en velopes containing iamin B receptor assemble prior to lamin import and lamina formation, and that lamina assembly drives male pronuclear swe lling. Several unresolved issues are discussed.
