Abstract excerpt

It has long been appreciated that spermiogenesis, the cellular transformation of sessile spermatids into motile spermatozoa, occurs in the absence of new DNA transcription. However, few studies have addressed whether the physical presence of a sperm nucleus is required either during spermiogenesis or for subsequent sperm functions during egg activation and early zygotic development. To determine the role of the...
